Joey B out here controlling an aircraft over a WIDEEEEE envelope on his f̶i̶r̶s̶t̶ second try, and I hope ya'll know just how hard that is! Aircraft control derivatives scale with dynamic pressure (combo of airspeed and air density)... This basically means an aircraft behaves very differently at different speeds/altitudes with the same control deflection. The successful flight is a testament to Joe's math all collapsing down and "un-coupling" the rocket from its environment, from aero modeling to control system design to sensing. Next video is gonna be good! TL;DR: 😍🚀😍

When you started in on canards, I started muttering "elevons". When you started talking about talking about rotation the whole fin, I nearly yelled "elevons" at the TV as well as grumbling in 737 Max overcontrol. Then when you showed your solution, I was like, DUH, elevons. Yes, I know the shuttle used a separate rudder, but honestly you should be getting the point since you had four "wings" instead of two. This is how supersonic aircraft control their flight. And if you see my name and picture, and recognize them, LONG LIVE THE PID. Glad I found your channel, we did know each other. And to really induce swearing you need to botch a Kalman filter.

My dad helped develop a few rockets for General Dynamics, they used something called “dithering” which made the fins vibrate(?) and when they wanted to steer in a particular direction they just made the fins spend more time on one side by interrupting the occultations, favoring the direction they wanted to go

It's fun seeing you go through the same problems I encountered about 15 yrs ago. I built a rocket with canard driven by high-powered rc servos. I put together a controller with an $1100 Analog Devices IMU and a custom microcontroller with SD card parameter control and data recording. I initially wanted to control roll. had 9 flights without success. At first I thought I had a control system bug, then I thought I might have a hardware problem. Finally I mechanically fixed the canard at a constant angle. I had roll reversal in every flight. I finally installed a camera to verify the data collection. Unfortunately the rocket came in ballistic and the 8 foot rocket was compressed into 8" long wad. I researched this problem and ran across a group in the NW that was having the same problem and had identified AIAA research that identified the problem many years ago.

@ledocteur7701 25 күн бұрын

The fins extra thickness didn't seem to be an issue, but if you do want to reduce there thickness in the future one option is to mount the servos inside the fuselage and have a thin shaft go up into the fin to control the tab. This could also allow almost all the cables to be inside the fuselage as well, further reducing drag.

Actually, building a supersonic wind tunnel in itself is not that difficult. Gathering the relevant amount of currency to do so, while building it in a place that is about 500 miles from your nearest neighbour........ different story.

@technikchaot 25 күн бұрын

As someone that studies Engineering Informatics (mixture of computer science and electrical engineering) I often have to work with computer science that had never heard any physics or mechanical engineering lectures and they are most times better at algorithmic and similar thinking stuff but don't let have mechanical or electronics ideas. Wind tunnel up to a couple of hundred km/h no problem use a fan big and fast enough and you are good to go. You still need to think about how to reduce the effect of the turbulance of the fan, maybe build a pull configuration the expected wind speed for the same input power is slightly slower but should still work. But now the trans and supersonic Problems. These speeds are not possible with a fan alone. And the pull configuration does nothing. If your fan is to powerfull you suck a vacuum but still don't get mach 1 and in the push configuration you still would only near to mach 1 and than produce a high preassure zone. So you need a nozzle the same type as the one on the bottom of a rocket engine. It solves the Problem of converting high pressure gas to high speed gas. BUT the gas goes from very high pressure (tens or hundreds bar (atmospheres)) to 1 bar or below every expanding gas cools down. And this kind of depressurization would lead at least to freezing water and CO2, but depending on the pressure drop even to liquid nitrogen or oxygen (unlikly in home build variants). So you don't need to start with a high pressure gas. You need to start with a high pressure high temperature gas. Problem is most materials get weaker under high temperature but the high pressure is really high so the whole thing is near its failure before you even have moving gases. Second Problem you don't want to see effects of pressure waves reflecting of the tunnel walls because that would cause similiar uncontrolable feedback loops as the canards to the fins earlier in the video. So the wind tunnel should be at least factor 5 to 10 bigger to the test object (model rocket) now we test a small model with a fin can that is only 5 cm in with (to be honest to tiny to have good estimates on how a big one would react). The wind tunnel has at least to have a diameter of 25 cm. 0.25m*0.25m*pi/4=pi/64 m² this times the desired speed of 300 m/s (yes I know speed of sound is faster under normal pressure and temperature but I will not estimate which temperature we could manage to reach in our tunnel) at 0.5 bar is pi/64 m²*300 m/s*0.5=7.36 m³/s. So you would need every second of testing 7.4 kubic meters of air delivered to your wind tunnel, forget it. This is for each second 4 full (and not the smallest ones) air bottles that divers use. Because there is no for not that rich individuals available solution that would produce this preassure and quantity of compressed gas on the fly (exeption rocket motors but they burn to hot to hold a normal test object in exhaust).

@manfredgawlas9936 25 күн бұрын

I'm working on aerodynamics of rockets myself. From what I've heard from a people who works directly with that kind of aerodynamic tunnels, just the cost of preforming a single set of tests on subsonic tunnel capable of fitting rocket this size is at minimum few thousand dollars. Not to mention building a supersonic tunnel. You can get good results just by simulations alone tho, I basicly work with that, Solidworks is a pretty good tool for obtaining such data and is extreamly easy to use. However I would questions it's results for trans sonic flows.

@petergudden 17 күн бұрын

There is a reason for all moving fins other than extreme manouvrability. At the end of WW2 aircraft became uncontrollable due to the elevator being behind the shockwave (where it looses effectiveness) just when they were very much needed because of the onset of Mach tuck (which is a nose-down moment on the lifting surface in transonic flow). The problem of controllablility was solved on the Bell X-1 with an all moving horizontal stabilizer. On supersonic missiles this is the all moving fin. Your trim tab seems to function more as a spoiler (so to create drag) than as an aerodynamic surface to direct the airflow. It definitely gets credits for a shoestring approach. Hope you don't mind me making a suggestion: spoilers don'' t necessarily have to be in the fin section, they might as well be in the aera where you would expect the canard fins or anywhere else on the vehicle. The obvious advantage of moving the spoilers away from the fins is the available space for the servo's. Now your fins can be thin again to reduce the drag. I hope this suggestion will help you past Mach 2 and eventually into space in a controlled manner.

Before I finish watching the video; there is a neat trick that the first AIM-9 Sidewinder missile used to avoid needing to compensate for things like density altitude: it used force servos on the fins rather than position servos. The result is that, with a few assumptions about the center of force on the fin staying more or less the same distance behind the pivot, a given turning force on the fin created the same side force on the missile body more or less regardless of speed or altitude. The entire guidance and control system on the first marks of the AIM-9 are a fascinating cases study in how a spec project with almost no budget can force better designs.

I think you bumped into the problem they had breaking the sound barrier with the oldschool split control surfaces. You've gone smart and made a teeny tiny control surface, but the split control surface becomes basically useless in the transonic region, which is why they moved to all moving control surfaces. You've probably already come to this conclusion, but if you put a teeny all moving contol surface at the tip of your fin, you'll retain control authority at speed. Having the surfaces that far out will make them more potent in roll as they have a longer lever, but hey, make smaller movements. Keep it up, it's an instant click whenever I see one of your videos!

Would having both perhaps help improve control through the transonic region? I would love a video on why that speed is hard to control flight at. I'm also curious about the fluid modeling, and how accurate different modeling approaches are. What data can you get before launching? What tools do you use? How much uncertainty do you have in the results? Looking forward to the next episode!

Amazing video, can't wait to see what happens next! I would love to see real footage side by side with the simulated footage for the next flight.

I've been following the Sugar Shot to Space project for what seems like 20 years. I dare say you're going to beat them to space. Subscribed. Good Luck!

As an Aerospace Control Engineer, this is absolutely amazing! Yes we would actually love to see more videos on control architecture and if you had implemented gain scheduling for pre and post mach flight!! Thanks a lot these video! All the best for future control missions

Love it! This is why I love engineering. There's always something you did not think about and finding the solution can be the most fun part. :D

Great video as always! I have one idea. Instead of going down the route of preventing the rocket / cameras from spinning, what about attaching cameras to each side of the rocket such that you get 360 degrees of coverage, then, stitch the footage together from all the cameras and un-spin it using the recorded gyro measurements during flight? You would likely need some high frame rate cameras to help avoid motion blur but from what I've seen on 360 degree videos on youtube, you can spin those puppies to your heart's content!
