Bright Star Assemblies is a small company dedicated to the design, building, and testing of our own aircraft designs. Those of you needing to contact me you may do so at: brightstarassemblies@yahoo.com I do not check this email that often but I do check it.
Speed boat shapes are more about stability. The edges and ridges allow the vessel to grip the water and stay straight. Your stages between ridges could help plane up but they will also cause drag
You can do away with pedals if you use fly by wire controls that include a “twist stick” for yaw control. It’s not a product on the market. It’s just a thing in my head that I want to use in my design. You build it first and you’ll own it.
You probably already know by now but you need more wing, either in length or in width and profile. Wings for this end of the aviation design work has pretty thick wings because lower speeds require lots more wing lift
I have a plan of making Hydrogen fueled planes based on the F15 just a bit smaller because the F15 is 19 meter long and my plane will be around 6-7 and i will put two 50 litre high pressure hydrogen containers at 700 bar and if i make the engines well they will be able to run it for 4-5 hours at 300 km/h or more.
Are you sure that the market is ready for this aircraft ? it has so many features that I'm starting to think it's going to be really expensive for the targeted audience.
You can design aircrafts in a game called Flyout, it won't be suitable to turn it into a real thing but it's really fun and fast and easy compared to CAD software, while still relatively realistic.
I'm a "Wet" flyer. I like the engines. Single cylinder, cast aluminum, Alcohol oil fuel mix. 2 cycle, little screamers. I Design and build primarily with Balsa Wood. "Build-up" ribs and wings. Flat sided Fuselage. Been flying R/C since 1976. Lastest.... 48x36 Blended Body Delta, this is build-up. Flown with 4 channels using Ail & elv mixed. Tri gear for the wheels. Engines used, .25 BB with a 9x6 prop, .46 BB with a 10x6. This thing is crazy fast. Hammerhead stall drop it's nose back flying in a heartbeat. Other planes, used or broke. 56 - 60 in Trainers, 40 sized engine 4 -6 channel radios. Look thru the dumpsters at flying fields salvage any airplane part (s) broken planes. Bring them all home and fix them. It's a hobby. I something new every day.
Great to hear. We have decided for the prototype to switch to the UL520si engine. The Aeronautical Engineer recommended more power than the BMWs could make. Daily because the aircraft is wide and has a lot of form drag. We have reduced the with of the fuselage by a foot as well. Thank again for in info on the engine.
I wish you luck. You can do it. One concern, the thrusters may pull in sea weeds. I had great deal of hassle with my water craft Yamaha wave runner and I had to dive under to pull them out by hands. If you can install a kitchen garbage disposal blades in the front of the thrusters will be great . GOD BLESS YOU
I have this idea of an asymetrical airplane for my fictional story, i feel like it would work flawlessfly but everyoen else tells me otherwise. Could you tell me if this would fly? It's shaped like a P-38 Lightning but the airliner-like passenger tube is on one of the sides where one of the propellers would be, and on the other is a giant engine the same size as the passenger area. The only engine is the one on that one side. Would this fly properly?
Thanks for watching the videos. Sure, I could send a file once I have the design finished. Recently we have moved the tail back a foot. We made the rudder and vertical stabilizer larger and we made the fuselage a bit skinnier. Next we will get the shape of the pontoons (floats) dialed in.
Really impressed by your hard work. I am an aeronautical engineer and recently I have been searching for a new aircraft design that can work with hydrogen fuel cell. You gave me hope to get a design and process too. Thank You so much.
Thanks a lot! It is a really cool design. We are still working on it. It is my passion and will get done. I presently have a lot going on in my life right now as does my CAD guy. We spoke yesterday and will be getting back to work on the shape soon.
Hahaha Thanks for watching. I sure hope you don't tell people who ride jet skis they are "Stupid". Maybe you never heard of water jets before and how powerful they are that they can cut steal. Humm
At 12:50 in the video, it shows the different compartments of the pontoon; I would recommend having flooded compartments (ballast tank) to balance out the aircraft while on water for a more comfortable ride. Which should be adjustable so when in flight it may be dumped to provide better flight control and filled in water.
Amazing video sir!! Hats off to your never give up spirit, its really apprciating, i was actually looking for an idea where i can design an aircraft of my own without spending hell lot of money over it and that's where i found your video. Thanks for the guidance sir .. 👍😊
I’m not an expert, but the sharp edge on the leading end of your fuselage may cause some separation. I’m also intrigued by your pusher prop idea, you need to be careful with that though and keeping it out of the water.
It would be cool to convert a small plane into a tilt rotor aircraft, but I know I can’t do it alone, I would require a team of experts who understand the aerodynamics of any aircraft as well as experienced engineers
Thank you. I thought that up on my own. I didn't want to use water rudders that have to be raised and lowered like most sea planes. I wanted something sleek and clean sheet design. At first it started off as a small troller motor that would extend out of the fuselage. But that idea felt cartoonish and maybe a bit hard to integrate. Then I ran across the idea of small water jets like they use on jet skis. But those are a bit to big for this. The idea isn't to go fast, it is just the maneuver the aircraft up to the dock with the engines shut down at maybe 3-5kts of speed.
Thank you so much! It took a lot of work. Now, I am much faster at editing videos. I have a second RU-vid channel called Retired Dream Life. Feel free to check it out.
Yea, don't worry about aerodynamics, structure, safety, manufacturability, function. Just get something "sexy" down on paper, then into a computer. Yea, that's the ticket. Function follows forum right or something like that. If you 'identify' as an aeronautical engineer, then you are one. I mean, after all, what's the point of surviving a trip, if you can't look "sexy" doing it. Good for all you commenters for validating his truth. Speak truth to power✊, what could possibly go wrong.
Hahaha Jeff, your sarcasm is not lost on me. I am the same way with my humor. I think if you watch all my videos and subscribe to this channel for future videos, you will see that this design will have all the components that you mentioned it is lacking. I never said I was an Aeronautical Engineer. I am sure Elon Musk never said he was a rocket builder, yet, he is putting them into space. I am not an Aeronautical Engineer and that is why I hired one. I am not a composite (structural) engineer either that is why I hired one of those. I am not a CAD 3D guy, that is why I have one of them working with me. You see, what I bring to the table is my dream and unwavering desire to get this product to market. This video you commented on is just a quick video to help inspire other out there who want to get their dreams off the ground. This is why so many positive comments. I offer hope and a little guidance. What did your comment offer? Was it constructive or helpful in anyway?
Fair enough,. Let me try and be a little more constructive. My concern is that your idea amounts to little more than a form. At least from the way it was presented here, it seems your primary design consideration is aesthetics. It seems you're trying to get the look of the product nailed down and have your engineers shoehorn their work into that envelope. This reminds me of the mini 500 project. So concerned was that guy, that his aircraft look like a scaled down version of the MD500, that the result was an aircraft with severely compromised performance and safety. Still, the aesthetic was sufficient to generate both sales and fatalities. Best case scenario with this approach is you create an aircraft that appeals to some because they think it looks cool, but is far to expensive to actually sell in any quantity. Think I'm being to critical? Fine, it's just one guys two cents on the Internet, freely given, and worth at least what you paid for it.
20 yr seaplane pilot. Interesting design. You will find that the sharp vertical inside edges of your floats will cause you grief when landing. It is not uncommon to have a little lateral drift as you land and that edge will cause large lateral force on the pontoon as it contacts the water.
Ken, thanks for your comment. The floats will be completely changed. They will look like all the rest of the floats on bottom by the time we finish this design. We have already made many changes to the shape of the aircraft and engines since my last video. There is a lot more to some. Thanks again
Having worked as a drafter for an aluminum jet boat manufacturer, i can tell you a bit about hulls, which you can use to inform the pontoon design. Also, while you may think the building of a scale model may not help prove the aerodynamics, I think that it is quite applicable to to helping evaluate the hydrodynamics, and the weight and balance at various speeds, taking off and landing. The jet boats I worked on had angled vee-shaped hull bottoms (called the Deadrise angle) The river boats that had to run in shallow water had 8 or 10 degree angles from horizontal, each side. The lake boats had steeper angles up to 20 degrees, for dealing with larger waves. The larger the deadrise angle, the more the hull can pierce the waves. (less slap.) So I think you want a steep angle at the front, and flatter at the rear.. so when you are landing at 140 knts, you benefit from planing at the rear, and piercing at the front.. but your pontoon volume along the length must also be proportional to the weight distribution. Your design looks a bit skinny at the front, meaning that it will be pitched forward sitting in the water.. so I do recommend spending some time with a model in the water and adjusting the weight distribution. Then you can optimize the shape of the deadrise for the planing and wave piercing aspects.. again.. experiment as much as possible.. fail early fail fast, and challenge all of your assumptions..
Chris, than you very much for your incite and wisdom. I would love to have a conversation with you on the phone. Please email me at brightstarassemblies@yahoo.com I can give you my number there. Thanks
Thanks for your comment. I am sure glad you cleared that up for me. In future videos you will hear me call them pontoons and sometimes floats. I prefer pontoons because it is a boat until it flies for the first time. As they say, it doesn't matter what you call them, they do what they are suppose to do.
Man thanks so much for making this video, I don’t want to design a full scale aircraft just yet, but designing an RC aircraft would be awesome! I’m going to dedicate time to learning about design, aerodynamics, and electrics to design a good RC aircraft!
You do not even sound as a technician. You need to be very good in drawing and 3D modeling if you want to get something created. Solidworks is a really good program to be in but you took classes and still could not make a part, come on...? I learn more about engineering just from reading books, watching youtube and create small projects then I do at school.
Thanks for your comment. I'm sure you watch Elon Musk building all those rockets as well right? haha It doesn't take anything other than a dream to make something.
I have a dream to build an aircraft of some sort that focuses on photography, I want to follow in my Great-Grandfathers footsteps in designing aircraft as he had contributed to the design of the A-5 Vigilante. I am only 13 and have no experience but I believe I can make it happen.
I hope you do as well. It took me years trying to find the right team members. There were several that tried their hand at it, but all lost interest and left. Now I have a solid core I'm sticking with. Best of luck to you.
So where do you put all the 12 volt batteries for the elec jet pumps? Much better weight problem solved using small jet ski engines. Or just use your already ample plane engines and leave out the jet pumps. Did I hear you right, its 400 HP?
Batteries? How many hours do you think you need running these two jet thrusters?? On any normal day one might run both thrusters at half power for a total of three minutes backing off a dock and three minutes taxing up to a dock. Sounds like you want to go cruising around the lake just using these electric thrusters. hahahaha But that is not what they are made for. To answer your question there will be one 12 vt battrie that weighs 11 lbs because it is an aircraft grade battery and it will run these thrusters for probably 30 minutes. But it gets recharged while the engines running. So, any normal person will only use them to back off a dock and then start up the engines. 400hp?? Nope, there is nothing on this aircraft that is 400hp. Those electric thruster motors will maybe be 1/2 hp each and the engines that we have switched to is 200hp each. For a total of 400hp combined. Maybe that is what you heard. Thanks for watching my video.
Dream on, a 12 volt deep cycle battery weighs about 60 lbs, That will last you about 20 minutes, and how do you charge that battery? I know put solar panels all over the wings,, thats another 60 or so pounds. So how do you make up that weight in an airplane? Well I guess you can make the plane a single seater. Its clear you havent thought this through much.
Honestly I have no idea what you are referring to. The battery I will probably go with is an aircraft 12vt battery weighing 15lbs. There is a link below to one if you want an idea what it looks like. To charge it there are two alternators on this aircraft (one on each engine) that will charge this battery when the engines are running. There will not be any solar panels on this aircraft at all. Anyway, I hope this helps clear up any confusing about these small electric thrusters on the floats. As stated above. These electric thrusters are not for powering around on. They are for pulling up to a dock or pulling away from one. They will only be run for maybe three minutes. Probably less. They will also not be at full power. www.aircraftspruce.com/catalog/elpages/odysseydry7.php?clickkey=9055811
Amazing, I am on the same path. I am finishing my master of science in the field of Ocean engineering Naval Architektur. I had been studing in Lisbone (member of Erasmus+ for best students). Still I have the same dificulties with using CAD software. In my proffesion seferal of those are used to design and produce any vessel or off shore unit or platform, like: Catia, Forran, Ansys, and many others. Huge respect for you, like your passion and how you overcome your weaknesses. Gain your knoldge and completed your vision. I know for sure that in the future I will see your design in operation.
Thank you so much for the comment. It is nice to hear such things. The design is moving forward but at a slower pace because I have gone through two jobs since the last video and my CAD guy has move to another country and gotten married. I have moved three times and spent countless hours looking for land large enough for a runway. I finally foundnit and purchased it. These days I am back to training at the airlines. Once I get finished with my training, I will get an update video out.
Very cool!! I wouldn't personally bother with the thrusters, just added weight and complication. The twin props will work perfectly for maneuverability. The pontoons, could be joined into a hydrofoil, creating both lift in the water and air, make for some smooth take offs!!! thanks for sharing!!! I'm subscribing :-)
Thank you for the comment. I agree with you on all aspects. Keep watching to find out where this design goes. I am in the process of making the next view but it will be months before it is out as I am presently training at an airline and can't focus on getting out a video yet. But it will come. We have made many changes already.
