The Line through the Clouds is called a Distrail - or dissipation trail, the opposite of a Contrail - or Condensation trail. Both have the same cause - heat and condensation nuclei from the engine exhaust creates localized areas where the water vapor is condensed into tiny ice crystals or water droplets. In the Distrail- the effect creates larger droplets from already condensed mist (the cloud) which are large enough to fall away, leaving an open lane in the cloud.

"so that's why we can't have sharp hydrofoils" I think what you meant to say was:"so that's why we need to make this thing supersonic" 👍🏻

@shurmurray Год назад

My 5 cents about sharp foils: recently I dove into hydrofoils thing too, designing impeller blades for waterjets. And when I was about to use some basic airfoil I suddenly found the airfoils for water are actually different (surprise) from airfoils for the air. The main reason is the cavitation. And the other reason - much higher water resistance: many hydrofoils do use sharp leading edge. Anyway - within working range of allowed angles of attack (usually something from -13 to +13 deg.) the sharp leading edge works ok.

@pawelrelidzynski680 Год назад

Was about to say that, due to the viscosity of water, a sharp leading edge is better. Look at boat/yacht shapes the sharp edge is at the front, contrary to airplanes where the sharp edge is at the back.

In water there is less resistance with a pointy shape in front, and i have seen it in a controlled environment. Same with air, less resistance when the frontsurgace is rounded and pointy in the back

The transition from hydrofoil lift to flight on the Regent aircraft seems to depend on a pitch-up "launch" to get more lift by increasing the angle of attack. While this might work, passengers might find such a maneuver more than a little unsettling.

@@XenoWiz more motors does increase the safety in case of a failure

@inventor121 Год назад

@@XenoWiz more motors actually generate more power than a single big motor due to tip speed limits. If your tips start hitting the sound barrier they won't generate as much thrust and will generate a ton of drag. As such you can run a smaller motor at much higher speeds and have more of the blade in the "optimal thrust region" For electric motors having a bunch of smaller motors has major benefits, the first being that you don't need to put huge amounts of current through a single wire (fire hazard). The second is for motor cooling, third is cost (a bunch of small motors is cheaper than a single big motor). The Blown Wing isn't a new technology, it's been used for decades on drones and has a long history with STOL. It actually does work since the effect of the wing is independent of the ground this allows for a functionally higher airspeed over the wing than your actual groundspeed, it's like taking off into a headwind. Momentum is conserved since the lift and thrust are (mostly) perpendicular to each other. The reason why airplanes traditionally favoured having one or two big engines is because that was also their main powerplant. ICEs are big and heavy, their power to weight ratio is actually very low compared to electric motors (batteries and fuel not included). Gas turbines have a thrust to weight ratio comparable to electric motors. So why aren't electric motors used in aviation as much? Well batteries are heavy, much heavier that fuel, and that tends to be the deciding factor. And jets generate just so much power so easily that it's kind of dumb not to use them despite their complexity.

@BikingVikingHH Год назад

Yeah, you dweebs are just noticing a particular movement of a test vehicle and trying to extrapolate it into an inescapable aspect of the final product’s operation. Nice try dorks. The reason why the flying boat has hydrofoils is exactly to *prevent* what you geniuses think it will cause; jarring vibration/shock. A normal flying boat rides on the surface of the water, planing before it rotates. That means that the roughness felt by the passengers is directly related to the roughness of the water’s surface. If a seaplane has hydrofoils, it can quickly lift off *above* surface irregularities, causing a smooth ride as it builds enough speed to rotate. The only time you’d feel the rough surface/waves is at initial acceleration stages when the speed is low and affect on the airframe minimal. Basically a little rough right at the beginning, then transitioning to an incredibly smooth hydroplane affect, followed by a rotation that I’m sure can be modified in it’s severity. They probably just made it look like it was “jumping” out of the water for a cool promo video. Y’all really need to look at the big picture, how the entire machine operates, and not just autistically and pedantically notice one single aspect and think your assumptions are that of a smart person….

@kinderdm Год назад

In regard to what you mentioned on the jet. Why wouldn't skis be the ideal solution to most of these problems? At low speed the waves aren't an issue on the hull. At higher in water speeds the skis will plane, lifting the body/wings away from the waves. And then at highest speeds, when your airborne, then the skis could be retracted like landing gear against the body for a smooth hull. This seems to give you the best configuration for all three speeds for takeoff/landing transitions.

@wiegraf9009 Год назад

Skis would induce a lot of turbulence and drag but yeah if they were retractable it seems like a good idea. I just wonder if they would really help ekranoplans with the choppy water problem because they wouldn't be very useful at cruising speeds?

@patrickmulvany6479 Год назад

Just a gut feeling - when there is no physical connection between an air cushion vehicle and the water, there must be less drag than if you dangle some shape, any shape down into the water. Your interesting experiments proved just that. The air cushion principle is so elegant in its simplicity. One hypothesis I'd love to see you try is fencing - i.e., Run a raked vertical fin down into the wateron the rear inner faces of your sponsons. Seems to me that you could extend the cushion of high pressure air further back, negating form drag from any horizontal surface touching the water. My theory is that fins would yield two benefits - first, lower form drag, and second, better lateral stablility. I'd love to see you throw some fins on your mature research aircraft!

@surfcello Год назад

This is the video I've been waiting for for ages! Your closing remarks are the most valuable to me: 1) Hydrofoils could help get GEVs and seaplanes out of the water, and perhaps aid in landing. 2) They'd have to be retracted to make efficient use of GE. 3) This bonus is not present at RC scales (likely due to smaller mass to surface ratios and lower Reynold's number). This had indeed been my hunch, but I'm so grateful to you for actually doing these tests and giving your expert's opinion. My motivation for the idea has always been the tell-tale fact that the Ekranoplan allegedly used 8 turbines to take off but only 2 for sustained flight. Perhaps one could also improve efficiency at sub-takeoff speeds by propelling the craft against the water rather than the air - e.g. by a mounting a boat prop to the back of the hydrofoil, or by creating a water jet with water sucked in through a hollow foil.

@RegisMichelLeclerc Год назад

Hi! I was so happy to see my mug in the "instigators' list" 😊 Thank you so much for making all the research and the tests. As you suggest in the discussion, hydrofoils would need to be short and possibly retractable (although they provide a tiny amount of lift in the air too, with some added instability). The goal is to leave the water as soon as possible to make the transition to and from airborne as fast as possible, especially in choppy waters -- the goal is to fly over the sea, which is *never* flat, even in a cove. From what you show and the Regent experment (I wasn't aware of this one), you'd use T-foils as they seem to provide more lift and less drag at low speed, and more than just one at the front spread around the CoG (i.e 1 ahead and 2 on the sides behind, or 2 and 2, adding to the same surface). Currently, I'm more on the Lippisch design (inverted delta) with 12º anhedral to which I add canards, the idea being to add 1 hydrofoil under the fuselage and 1 under each of the floats located at the ends of the wings, so to transition as quickly as possible to airborne. So far, the canards are attached to a nacelle at the front (like big ears on the head of a flying duck) because I wanted to have wings swept 30º forward (making an skirt open 120º in front), but I probably drop that to no-sweep and have the canards attached to a straight edge so to modify the entire wing geometry by moving the canards'edges up and down. Thank you again for all the work and the actual experimental results you provide. Keep up the fantastic job!

@bjrn-oskarrnning2740 Год назад

Just to save you some money in the future: the steel you buy usually isn't hardened, so high carbon steel isn't harder than regular steel (mild or construction steel) unless you actually temper and aneal it. Not that it matters a lot in those quantities, but tool steel is about twice as expensive as mild steel :) Additionally, brazing might be a better (easier) way to to attach pieces like that without sacrificing much strength. Anyway, awesome and educational video as always!

@FiltyIncognito Год назад

PSA: Be cautious about what craftsmen/tradesmen tell you about heat treatment. Many of them are notorious for getting it wrong because they tend to learn by word of mouth and trial&error rather than reading about material science. And we all know how the game of telephone tends to go. Heat treatment is a science. A branch of material science, to be exact. And it's complex enough to require highly educated and dedicated specialists when doing R&D for big expensive projects. Anyway, annealing undoes tempering, and tempering improves strength, not hardness. Quenching fast makes it hard, though also much more brittle. Tempering reduces brittleness whilst retaining higher hardness than other processes, which ultimately increases its' overall strength. Coincidentally, that metric is called 'ultimate strength', which is different a completely different metric from 'hardness'. Look up the tests for measuring those two. Annealing is the process which kind of 'resets' steel, typically used to maximize machinability (make it softer/more easily workable) and remove internal stresses due to forging and machining processes. It's also typically quenched more gently so you aren't left with an overly-brittle product.

Hey I'm in a video, cool! Thanks for the mention. Excellent exploration of the concept! It's cool to see the historical applications of the tech, so thanks for including those. Ventilation is the WORST when winging, I think that's the appeal of high dihedral front foils, although you rarely see it in rear stabilizers. I'm sure you've done plenty of research while making this thing, but if you want to get into hydrofoiling, there's plenty of money in the industry now, particularly wingfoiling, since it's the new hot thing, so lots of watersports companies have been investing in research to create the best hydrofoils. It's neat to see the differences in performance, high/low aspect, lots/no dihedral, thick/thin wings. I was toying with the idea of creating a biplane style hydrofoil, where the lower wing is smaller, creating less lift, but less drag to provide a gradual transition to flight, but you've proven pretty well the combination with ground effect aircraft isn't super compatible. Well done, keep playing!

16:20 looking at it, I'd say that it's almost certainly possible to land it without stalling at 52kts-- taking off would be more difficult, but the ground effect should help it reach the speeds it needs (for example, in soft field takeoffs, we lift off much sooner by applying full back elevator pressure-- however, once in the air, we immediately let off pressure, and stay in the ground effect until rotate speed). I'm pretty sure that plane's wingspan is long enough that it can be in ground effect without the hydrofoils being in water, so I imagine that's how they'll do it.

Wonder if having a different wing profile would be better for hydrofoils, maybe even capturing the ventilation/cavitation air bubble and using it for lift. I know there are some boats with flooding compartments (flooded when not moving, for stability. Empty out as the boat starts to move for higher speeds.) Applying this concept to a hydro wing make me think of basically one with a front slat, but the slat is attached at the bottom. Or just a channel slightly behind the top of the wing profile. My thinking is that at speed this would create a pocket that would either just help with lift, air is lighter than water an all that, or serve as a vent to bring the gasses along the foil and out of the water, away from the wing itself.

Excellent video as always! With regards to the use of hydrofoils, Regent are selling their addition as a different phase they can operate in. Ie they can operate in an area close to shore on the foils at relatively high speeds without the wake. When they then get out in the open they can proceed to flying. Rather than solely a way to get the craft out of the water more efficiently. The thing to be concerned about with foils is the possibility of ''hooking' them in the water at high speed as happened with the X114. The Seaglider retracts them to avoid this. But there is still the concern about the conflicting aerodynamic/hydrodynamic forces/moments between foil and wing lift. They are very hard to marry up.

@BikingVikingHH Год назад

The reason why the flying boat (Regent) has hydrofoils is to prevent jarring vibration/shock; A normal flying boat rides on the surface of the water, planing before it rotates.

Basically a little rough right at the beginning, then transitioning to an incredibly smooth hydroplane affect, followed by rotation. It actually makes a lot of sense. Same thing with landing; land on the hydrofoils, then by the time the plane decelerates enough they don’t generate enough lift to lift the airframe above the water, the plane is going slow enough that the rough water won’t be too abusive to the airframe.

@rctestflight : Maybe the submerged part could be used as an automatic pitch control if its design was different: I imagine a boom protruding 30 cm at the front, on the central axis, an a curved ski (like a comma) attached to the end. It could be a thin (5mm wide?) carbon strip, like the one we use to reinforce wings etc, which elasticity will provide the curved shape under the stress, and a dampening of the waves. Maybe you will have to overlay several strips like a leaf spring to have a more rigid front. Then tune the angle of the entry in water so it maintains the plane pitch close to the stall angle...

You know its technically illegal to sell titles in the UK. I see this time and time again of companies using US RU-vidrs to advertise this. There has been many instances of people "flaunting" or attempting to advertise their Lord or Lady title they have bought and being arrested. YOU GAIN NO UK HONOURS FROM THIS. The company that sell these small plots of land just has "permission" (which is dodgy as it is, as they could literally just make it up that you are buying a piece of land) from a land owner who has ACTUALLY been properly given the Lord or Lady title. In ANCIENT English law, if any land owned by any such title holder was sold to anyone else, than that person would also adopt the title themselves. However, this is not real today as no in those olden times, sold a singular sqft piece of land. It was a waste of time and land was precious. Lord or Lady titles may only be used when anointed by a member of the royal family, Duke(Duchess) or Baron(Baroness) in today's law. The ONLY way to gain any title properly in Scotland is to buy a Scottish Feudal Barony. They can start at $100k, with recent ones auctioning off for over $2m... Claiming a title such as Lord or Lady can be tried and prosecuted in court. This is known as "Cash for Honours" which you can look up if you wish.

I learnt from one of your videos that I can replace the battery on a Dyson vacuum. This saved me from buying a new one. Thanks mate!

Very cool have always wanted to see if a hydrofoil would work on a plane. On my electric foil board it has 2 wings front and back to stop pitching. Or try the piercing foils plus making them retractable could ultimately work the best.

I imagine we will be getting a full version of the song at the end??? that was amazing and earned my sub!

@dennishudson9723 Год назад

My thought is to have hydrofoils that have a slight downward pull or rake angle I’m using a little more power could find an equilibrium that would keep it from lifting out of the water? No idea if it would work but that’s the hydrofoil use I was thinking of.

Your best video dude! wrapping it up with another hilarious jingle

@Kael87full Год назад

Look into Moth (Ship class) they use submerge foil and a analog simple system to adjuste the foils at the depht needed

Very interesting video. I'm impressed. How did you achieved stability control? Any links?

@dvlofaustin Год назад

@rctestflight - Could you try moving the Surface Piercing blades to the outside? Seems like your setup down the middle is creating more drag?

Great take on an interesting area of developemnet , The Americans spent a lot of time on foils on seaplanes ,in the 1940s ,not a lot came of it ,I now see why maybe . An Aussie guy has gone water ski waywith his boats, 'sea ski', may be the best solution for a lighter 'water form' for amphibian and sea planes . Of course modern materials can make lighter stronger hulls too .

There are hydrofoils that use supercavitation. This is just forced cavitation at higher speeds and can increase both top speed and efficiency. I think the largest benefit to adding both ground effect and hydrofoils into one vehicle would be it’s very high weight capacity; high weight would also help with the foil staying close or in the water… last thing, foils can also be used to pull the craft towards the water preventing the bouncing created with ground effect.

Good work on finding the camera. I lost a GoPro 10 at 35' depth. Found it a day after I lost it with a fresh tank, There is not a good GoPro mount available to anchor one for static underwater video. I have been filling goosenecks with lead pearl weights. Works OK.

Best example of book/internet knowledge and actual knowledge. Lots of people think they know stuff because they read about it, but real life have its own rules. People love to comment trying to correct someone or give suggestion when they never saw or try that in real life by them self.

@latemanparodius5133 Год назад

Given the high drag, would sweeping the hydrofoil wings be beneficial? There would be more material, but the angle might make it shear through the water better. I'm reminded of the transition between subsonic and supersonic flight, and also of the machining principle of an angled cutting tool shearing material better than a tool that is flat on.

@powwow151 Год назад

I think the skis might work like the Sea Dart used. A newer aircraft Burt Rutan made called the Skigull uses a similar approach as well

@phibin777 Год назад

watching your progression with the ground effect stuff, 'take off' always seems to need more power to achieve breaking the surface? with the hull drag on water, and you cure this with your par thrust tilt motor set up you said with an aircraft having a hydrofoil hanging is a lot of drag? could you make a retractable foil? so you can get lift from the surface really easily with its lift then as soon as you get enough airspeed for the ground effect? retract the foil :) i guess the challenge there would be to make a boom that didnt have tons of drag. and to keep the foil in line with the aerofoil while retracting im sure with all your engineering know how.. you could make it happen as your half way there already ;) love the vids dude keep it up !

@mattymerr701 Год назад

Would making the arm of the foil more rounded or have less depth fix the yaw issues? Make it so that at whatever angle of attack, the forces balance out more?

Back in the 70s the Air Force Research Lab put a hovercraft guts on the bottom of an airplane (a C-7 Caribou IIRC, called the Air Cushion Landing System or ACLS). Not sure what their results were, but it sounds like something you would try.

@sgt-stealth9949 Год назад

Hello, I am an embedded systems and aeronautics engineering student and I think you can keep the hydrofoil in the water by increasing its surface by making it longer but also larger. u could also place the rotors behind the aircraft (like the sr71 for example) and move the hydrofoil more towoards the nose/front of the aircraft. so the thrust is coming from behind and its helps stabilisation, or even better ur can do the opposit keep the rotors in front and bring the hydrofoil more the back you should try it actually it could be interessting keep in mind that performing these two ideas might introduce the need to add a variable angle hydrofoil for way better stabilisation !

@kiuperhyper5795 Год назад

Remembering what you said about all ground effects being able to, with enough power, fly, I thought about how crazy it look to see a lun class ekreno plan flying at the same altitude has a fighterjet

@justusschiszler1926 Год назад

I would try to do it the other way around. Like a foiling boat that also uses groundeffect. With a propeller in the water and not in the air. just using Ground effekt for extra lift.

@nikolatasev4948 Месяц назад

About the Regent Seaglider - their prototype also has wingtip pontoons whose holders (not sure of the technical term) prevent the air from escaping sideways and thus increase efficiency. For added bonus, I suppose they act like winglets and help in airplane mode as well. Not sure why they don't have them in the final design. Plus, as mentioned - high wingspan helps keep efficiency even if the wing absolute height is... well higher. Which, in turn, helps operate in rougher weather. Reverse delta ground effect vehicles can also get away with higher wings (at least their leading edge). Also not sure why we don't get more of these.

8:00 This is so fascinating. It's like how a truck has better fuel efficiency with the tailgate up even though you'd think that would produce drag, but it actually doesn't as it's designed to create a pocket of turbulent air that the other air just flows around. Driving with the tailgate down removes a tiny bit of theoretical drag from the tailgate, but adds more drag around it because it gets rid of that pocket.

I love, love, love the hydrofoil. Tweaking the placement is great. Since water is 800x denser than air, would it make sense to make the foil 800x smaller than the wing for a comparable lifting force?
