🤔I'm not sure if it counts as within the scope of his project, but I'd imagine you could put a tiny computer in there, to automate some of the control-adjustment. (For example, near 20:00 when he's got issues switching between forward flight and hovering, and the pitch changes abruptly.) Although maybe that'd require a bunch of speed/accel sensors, and then all become un-calibrated with varying wind speed or something. 😆

@@AileTheAlien yeah, it’s in an « attitude hold » mode, meaning that whatever manual angle he puts it in, it will attempt to keep. So it’s not like a mavic or something, but that not the point.

@RobofGabriola
@RobofGabriola 10 месяцев назад
Retired helo test pilot here. I think that the abrupt pitch you experience during deceleration might be rotor flapback. Most helos exhibit similar behaviour to varying extents, and yours is exacerbated by having turned off the stability augmentation. A partial cure might be a VERY slow and shallow deceleration to the hover, with correspondingly low nacelle rates. I agree that the longitudinal movement of CG is also a big factor. Incredible project! Congrats.

"The tailheaviness" when you go back to hover mode is not only because of the motors changing their position. When going back to hover mode you still have some velocity thus wings still produce some lift especially when the flaps are down. In real or simulated V22 Osprey you can also observe the same behaviour. It is up to pilot to take a correction for the nose going up on transition. Impressive work!

@samos343guiltyspark
@samos343guiltyspark Год назад
@@billmiller4800 this is exactly the solution real airplanes use. As airplane velocity changes, tail angle changes. Pitching downwards lifts the tail which is good for low speeds where not enough air is being compressed under the tail to give lift. Pitching upwards eases off this angle and consequent tail lift for high speeds where there is ample lift under the tail. BUT here's a thought, maybe, if the thrust the motors provide is actually good enough, then for full speed mode tilting the tail even more to get the nose to point upwards just a bit should keep the aircraft climbing... Unless the wingspan and/or thrust really is just not good enough.
@nekononiaow
@nekononiaow Год назад
Indeed but for a drone, it seems undesirable to require the pilot to do such compensation. It is probably better to have three distinct stabilization mechanisms: one for rotor mode, one for forward mode and one for transition mode where pitch is used to compensate while the rotors tilt.

@KptnAutismus

i think there would be an insane amount of drag and slop in such a system, it would make the motor-pulsing part very hard. the weight shifting via moving the battery is more plausible imo.
@BladeScraper
@BladeScraper Год назад
@@KptnAutismus A long shaft and a couple of bearings wouldn't add much drag at all. Plus, the latest design doesn't do pulsing anymore, it's just using regular (ish) props with a fixed angle. I think it could be a solution worth looking into. The main issue I can see with that idea would be the added weight of the shaft in general, but that could be minimized greatly by using hollow shafts. The load on them isn't all that much, RC helicopters almost always use hollow steel shafts these days and the forces there are much much greater. It wouldn't need to be a very large, heavy driveshaft.
@RiderAnton
@RiderAnton Год назад
@@KptnAutismus it probably depends on the material used for the shaft and how long it would be. A steel shaft offset by only a few inches might not cause too much twisting when pulsing the motors. I think it would be interesting to see tested even if it doesn't end up working
@chris993361
@chris993361 Год назад
Instead of a shifting weight, I can't help but think moving the motors further down into the nacelle with an extension shaft out to the prop would give you a more balanced weight profile in the nacelle that doesn't change when they rotate.

@DZARO
@DZARO Год назад
*Improvement suggestions:* I would start by increasing the transition time from half-hover to full hover to at least 7 seconds, if not more. A slow transition will help you with the gyroscopic effect created by the rotating props. Secondly, you have a lot of slack in the servo connetion that is controlling your gears for both the rotation of the main axis as well as the rotation of the individual motors. You can fix this by adding some damping oil (such as the one used to dampen the throttle stick on transmitters) to all the those gears or by adding multiple intermediate gears to have a more gradual torque transition. In the shots where you were showing the tilt mechanism working, it was a bit juttery. Finally, ballance the whole motor mount on the axis of roatation by adding counter weights to the bottom / back part of the motor housing. This will ensure that you have no changes in CG when the motors are rotating between hover-mode and forwards-flight-mode (or any stage in between). Another thing to note is that not only are the props are actying as a gyroscope, pulling the body down when you change orientation, but your whole body-wing system has to oppose the motion of the motor mounts rortating in the opposite direction. You can easily do this by removing one gear and just ballancing while the whole thing is free rotating. Alternatively, as suggested by @Cassius Wilhelm, you could add two separate batteries as counter weights. But make sure you have enough mass in the centre of the aircraft because if you make the arms too big, yaw intertia can become a problem. Try to have a 1-3-1 or 1-2-1 weight ditribution, i.e. first digit for left wing, second for main fuselage and tail, third for right wing. Relatively speakeing, the less mass you have in the wings and the more mass you have close to the CG, the better you plane will perform in almost every way. *Things to check:* Make sure that the thust angle is not sagging , i.e. becoming negative, when you transition your motors to forwards-flight-mode and make sure that you have disabled the two servos that control the pitch of the motors themselves. Check that the final position of the motors is not below the the chord line of the wing. If they are effectively pointed down, then just adjust the endpoint of the main tilting servo to allow to finsh the rotation with a little positive thrust angle. *Things to re-design:* Just by looking at the wing to body ratio (18:46), I can see that your wings do not have enough surface area for what you are trying to do with it. It is not uncommmon to have a longer chord line when trying to build scale planes of any kind, simply because the wing loading and the generated lift is very different and for a plane like this, you should have as much wing area as visually possible, i.e. if get's too large, it will look strange and no longer "to scale". Just compare the lift-to-weight ratio between the full scale aeroplane and yours and you'll see the point that I'm making.
@cassiuswilhelm9640
@cassiuswilhelm9640 Год назад
For the counterweights I would like to suggest using two batteries, one in each motor pod wired together as that eliminates the need for a dedicated weight shifting mechanism and allows using the weight that would have been on the plane anyways more efficiently. Please feel free to add that little idea to the root comment.

@@cassiuswilhelm9640 I added your comment and tagged you because it is a good idea, but I don't know if this will be very benefitial for roll and yaw stability and overall stability because he uses differential thrust to control yaw in horizontal flight and well as roll in hover mode. You can think about it like this: You and your equaly weighing friend are sat on a seesaw at the park and you are oscillating up and down. The further out you sit and/or the more you weigh, the more force you will require to slow yourself down and bounce back up. If you are light and/or sit towards the middle, you don't need as much force because your rotational inertia is not as high as in the other case. In @Tom Stanton 's case, it would be beneficial to have as little weight as possible in the wings so that when he rolls or yaws, there isn't much roll or yaw intertia, respectively. Also, adding weight far away from the CG will have a huge impact on PID tuning, but he will have to do that anyway. Hope this makes sense. :)

@bladesofthunder9778
@bladesofthunder9778 Год назад
very nice. The solution to your Centre of Gravity shift during transition is to balance the nacelles so as they move the balance point doesn't shift. you will need to move the motor back as a counter balance to the head. I would even consider mounting the batteries in the nacelles too. Also the swash plate design is a far better method of control as it allows for a constant head speed even in wing borne flight using collective pitch to control airspeed and very precise cyclic control in hover. Suspect to get it fly nicely in all aspects your going to have treat it like a conventional Tandem helicopter and plane rather than a drone. But its is great to see.
@unclejoe1116
@unclejoe1116 Год назад
Came here to say this. The simplest solution would probably be to add a longer axle to the motors, moving them closer to the pivot point, which also moves more weight much closer to the center of lift and the center of gravity, both of the nacelles and the aircraft as a whole.
@benanddadmechanical6573
@benanddadmechanical6573 Год назад
Is there any reason why the motor can’t be mounted at the level on the wing spar and drive the rotor head via a shaft? Still tilt the rotor head but have a universal joint at the rotation axis for the head. The other options you brought up with weight shifting a battery or counter weights in the nacelles sound … overly complex? I’d think the only acceptable ‘counterweight’ in the nacelles would be the battery(it’s) them selves.

I don't think that the plural of software is softwares, in the same way that the plural of lego bricks is not "laygoes", the singular of saving is not savings, and the name of the bit of a race track which isn't curved is not the "straightaways".

That Cg shift could be fixed by offsetting the motor tilt servo to the back of the nacelle and using a linkage instead of gearing. You have plenty of space inside the nacelle so it should be possible. In general rotating things should always be balanced, especially if it's a flying thing 😉 Anyway, awesome project as usual. It would be great if you could show a bit more of the process that goes into the stabilizing algorithm and the command and control. Also hope you get to use all these weird rotors in another project.

Had the same thought. Moving the motor back to the center of rotation and using a "drive shaft" to the front of the nacelle where some kind of ball joint (like in a FWD car, I don't know the technical term) sits, to enable the pivot motion of the rotor.

Yep, I had the same thought. Also might cheat the motor position and/or the pivot location to help achieve a balanced nacelle. Might lose a tiny bit of scale perfection, but it might be worth it.

Really an awesome project :) What about adding two smaller batteries to the lower (back) part of the nacelles? I imagine the original has the pivot point around the center of mass of the nacelle and by moving the batteries in there you might automatically shift the battery as needed.
@markdriedger9464
@markdriedger9464 Год назад
My first thought also! Use the batteries as the counterweight. And consider the suggestion of a longer shaft on the motor below. Combine these two, and you can probably get the CG to stay put during the transition.

Very nice. I’m a ex Spacex employee/current helicopter pilot. From the video, it looks like it needs more tail pitch authority. It was interesting watch you work through designing a rotor head. The reason that the wind sent your “fully articulated” version into uncontrolled flight would be due to dissymmetry of lift. Very neat project. Well done.

Regarding the shifting of mass of motors. I think another solution to balancing the motors would be to drop the motor further down into the pod and add an axle to transmit power to the prop. Of course this would mean adding another bearing but the weight would be significantly smaller than a counterweight while still achieving the desired effect.

I believe what you are experiencing in transition to hover can be a mix of two things, the weight distribution and something called Vortex Ring State (VRS) which is common in both helicopters and tiltrotors like the V-22. I recommend lowering the servos in the nasales to help with COM, and for VRS you could and a function to the transition key on your control to modulate your throttle to be less powerful in half and forward flight. When switching back to hover you increase throttle to maximum to flush the VRS phenomenon. I hope this will help can't wait to see more videos on the topic.
