@ryguy81538 2 месяца назад

Someone may have already commented on this and it might be obvious to you, but a big reason the plane is so unstable during the motor burn is it's not pushing through the center-of-mass. It's strapped haphazardly to the top of the craft causing it to nose dive down as soon as it's ignited. Placing it centrally in the back or adding another motor underneath is a possible way to correct this. Always love your uploads though. Keep up the good work.

I was on my way to comment the same thing! also mounting the rocket motor further back on the plane will help.

@avialexander 2 месяца назад

Or, you could angle the rocket to point back and up, so that the thrust vector passes through the CG. It will also push the plane down, but if it's already moving through the air all you need to do is increase your angle of attack to get a little more lift. Or you could do what JATO's do, and hang the rocket underneath or to the sides, pointing it back and down but still through the CG.

@baudouindesaintroman6337 2 месяца назад

I don't do avionics, only pyrotechnics and solid booster engineering, but yes it seemed to me that it would be much more stabilizing to put the booster under the wing level... Also he modified the balance and weight of that plane way to randomly 😂

@avialexander 2 месяца назад

@@baudouindesaintroman6337 Rockets are one of those things that mess up the whole "if it looks like it will fly, it probably will" heuristic. I think that's what we're seeing here, the complicated dynamics of rocket thrust and mass are hard to optimize around, so most people just slap a rocket on top of the plane since it feels correct. I blame 50's-70's pop sci artwork for this misconception.

@mike1261 3 месяца назад

Back in 1980, in a time before computer aided design, I build a SR-71 Estes-type rocket from scratch. I referenced photos from a magazine and used balsa wood & paper tubes for most of the materials. It was about the size of yours. Being a fairly heavy rocket, it had two D-size solid propellant motors, one in each engine. I was quite fascinated by the Blackbird at the time, but extremely inexperienced at building rockets. Needless to say, it flew, but not very straight!

I made mine in about 1990. I even followed the guide to paint it with different black paints, some flat, some gloss, to simulate the different surfaces. It was maybe my 3rd rocket. I never actually flew it. I spent so much time on it that I was afraid to launch it. Years went by, got interested in girls, and it hung in my room for years. My mom probably threw it out at some point after I moved out. It was beautiful though. I spent so much time on it. After spending months staring at it at the hardware store. Wish I would have launched it.

you need to stop mounting the rocket engines to the top of the plane . they need to put in the back like the fans but in the middle . desing the same plane model but with the option to put in the rocket engines in the back like a fighter jet . and put 2 rocket engines in the back not one .

You can can rocket motors that are essentially just multi stage boosters, you literally cellophane tape them together and when the flames hit the tape, it melts, drops off the dead Booster while igniting the second stage. More boost with less weight. Mounted underneath it with 2 boosters then the final motor with recovery chute.

@richardm.newlands2417 2 месяца назад

Ah James, this is your best one yet, brought a tear to my eye! Brilliant idea brilliantly executed! Just a few minor thoughts: Agree with everyone else who's suggesting a bungee-launch. FYI these incredibly low Aspect ratio deltas are a bitch in roll, because the stubby wings provide damn-all roll damping. And at higher angle of attack, the vortices spiralling off the leading edges tend to bang into each other over the aircraft centreline, causing a roll oscillation. So if you can shoe-horn a rate gyro into the roll channel it'll make life so much easier. I so just love this video!

@jordanliszewski6549 2 месяца назад

@@TheRattleSnake3145 Kind of a silly comment. ELRS wins over older control links like spectrum in basically everything, it's cheaper, receivers are smaller, it's range and link stability is insane and it's open source and always improving further. People have gotten over 100km of range with 2.4 GHz ELRS, basically for a normal usecase you never have to think about range ever again with ELRS. Additionally it comes with lots of additional features, adjustable data rates, model match, the ability to access settings on the flight controller flashing over WiFi. You don't have to switch to a different control link if what you have is working fine for you but for controlling things that fly, especially fpv, having a long range, high performance control link that never failsaves is a very good idea.

@Aero-100 2 месяца назад

Removing the engine cone was a good idea because it's used to compress air, but if you wanted more power you should add a compressor stage (from the turbofan engines) and put a primary fan in the front to suck all of the air in, and by that, where you put the rocket engines you should put in the front a intake because air sticks into a body when moving, then connect it after the primary fan. You could also have heaters inside of the engine so cold weather heats and you get more force. If you did that with only 1 engine vs 4 old ones you'll get even better power.

A standard planform airplane designed for subsonic flight would be more easily controlled, easier to see the orientation and easier to launch. Perhaps you could try a small diameter folding prop with a motor brake to stop rotation of the prop when the rocket is ignited. Having the rocket pointing out of the tail cone should make it easier to keep the center of thrust aligned with the center of drag.

Great video, very fun to watch. Few tips though, don't do high speed runs without a gyro because not only you were losing speed going right, but also losing speed going up and down. For that though, you will need better avionics and custom code depending on the airplane's characteristics. i think doing that first is better than hastily slapping on a rocket motor. Also, there is no problem going a little bigger and doing the aircraft shape yourself.

Really nice video. I just thought it would be really helpful if you add for example a DJI O3 or some Walksnail system to your planes. You would have HD transmission and onboard 4K recording. On top of that you can use the gyro data from the O3 to stabilize the Video. And with up to 10 km of range you could easily test long burn rocket motors without having to turn around. Overall the handling would be much easier.
