- MAGMA Fluidic, the second of the MAGMA aircraft, has performed controlled flight without the use of external moving parts, a breakthrough in aviation technology. A team at the University of Manchester has designed and built the aircraft in partnership with BAE Systems which uses circulation control and fluidic thrust vectoring to control in pitch and roll.

What commentators must realize is that the purpose of this project is not to shake up the aerospace research community. It is to give these students experience that will help land them careers soon. Excellent sponsorship.
Jeti radios and Hacker parts. Interesting how the FAA wants to deep six all the modelers in the US but if it weren't for all of our modeling products this nice test would have been very hard to get in the air to even test. Marvelous.
Thrust vectoring and blown controls have been in use for quite a while on some high performance aircraft it was called laminar flow control a series of slots cut into the wing with a kind of fan blowing air out of those slots
Henri Coanda discovered the effect around 1910, so 110 years ago, not 200.
reactive is air braking using flaps, proactive is this, vectoring is well known.
Control surfaces, control jets, no one is looking at the worst case scenario
minus both = redundancy. No harm to investigate concepts further.
That was great, something new i learnt. thanks
so... what's your conclusion? any real benefit? or just more complex engineering to maintain, like the laminar flow suction ports.
Very impressive!
Any ideas how this could potentially help blended wing aircraft? This could potentially help stealth planes by not requiring them to change their shape & keep their signature low when maneuvering or also give commercial blended wing concepts a potentially more efficient way to control itself, especially since now the force output can be from the air pressure sent through and is not limited by the airflow over the wing
Very interesting approach. Congratulations!
But you still need actuators to control the flow of air. How do they compare to typical control surface actuators?
Just perfect .....
Interesting engineering.
Impressive 👍
I thought this system will works beter as hydrofoil control due to more dense fluid? Maybe, but to steer a flying boat is diffrent because not using rudder instead using back foils, i dunno but this area are still sexy to observe
I thought the same, a ruder makes a lot of drag so that tech could be used in fins or hydrofoils to improve efficiency and reliability.
I don't doubt they have a powerful and effective control system but what happens if the engine shuts off ,movable control surfaces still work unless its some kind of fly by wire
Bail?
what if the mecanism of servo fail? is the same. For that we invent redundancy sistems. they can add 2 dyson to blow air on each tail when motor fail and the plane is planing.
Might be OK as long as the air flow for the vectoring is produced by a subsystem (blowers) that are completely independant of the thrust system. It does, however (to a layman) appear to introduce several new points of failure.
external moving parts are always easier to replace than internals
External moving parts increases RCS
Internal, non-moving parts generally require replacement much left often. On the majority of full-sized aircraft control surface actuation is all internal anyways.
How well do the circulation controls work, in the event of disrupted airflow over the lifting surfaces. If I understand the circulation control system correctly, at that point you wouldn't be redirecting laminar flow, the jets of air would be acting as thrusters. Do they have enough thrust to reassert control authority over the aircraft. This is very fascinating & I have so many questions.
What are the sizes, all up weight, wingspan etc.
A thrust vectoring triangle design🤔 makes me wonder if future Stealth Planes such as The B-21 Raider will have thrust vectoring lol probably not🙃
🔵 @ 1:07 the illustration used for explaining the 'Coanda' effect does not make sense to me, you say "The air is exiting the slot at the rear of the wing at supersonic speeds",.... however, the illustration does not show where the air enters anywhere INTO the wing to be able to exit OUT-of-it by way of the rear-slot.
yeah, definitely not supersonic. likely a mix-up since the air IS going much faster than it was inside the wing due to the compression
the air into the wing is likely fed by the engine intake in some way, that way the engine can use its intake fan to force air into the control system without needing to use unreliable ram pressure
EDIT: supercritical not supersonic, its a fluid mechanics term that likely got mistyped
The Coandă effect or the diversion of fluid jets near curved surfaces is an effect that bears the name of the Romanian academician, scientist, physicist and inventor Henri Coandă.The effect that bears his name was first observed by Coanda in 1910 during the test flight of this aircraft, called Coanda-1910. However, the test resulted in the destruction of the plane. So is not 200 years old
How do you control the aircraft when the engine(s) fail?
do you get more or less thrust.. what creates the compressed air
what happens when you lose power
Hi Johnny, there’s a paper in the description, have a read
isn't it a problem at high altitudes with freezing up those airchannels?
That's been a problem with lots of aircraft components for a long time. Heating wouldn't be an issue I don't think that heating would be an issue should this be implemented on a full-scale aircraft.
4 meters plane?
Iran has them now.
Why not use a standard aircraft body?
Why not think outside the box, stretch their wings and challenge their brains? Only then there will be innovations, new ideas and technologies. If they got it right, they got a new knowledge. If they got it wrong, they got to know of a solution that won't work!
☺👍💚👏
Very interesting. But please never, ever use that god-awful background electronic noise - thank you. It would be good to compare effectiveness of the two systems too.
Huh??
Sony i'm on japanese
コイツは、一風変わった、リアクションコントロールですね。
まあ、物理学的に言えば、操縦翼面を使って操縦する方法もリアクションコントロールなんですが。
スラスターモーターを使う方法と比べて、構造が簡単で、デッドウェイトも少ない、良い方式の様に思えます。
今後は、有人機を制作して、操縦者の操縦感覚に如何に整合させて行くか？。が課題になると思います。
Why aren't ALL planes flying wing style?
Lol millions of reasons.
Flying wings have lower performance due to low values for Oswald's Efficiency Factor. It is the result of having high Cdo due to the washout or reflex needed to achieve static stability. Fly by wire active control systems with an unstable aircraft config might avoid these low performance issues.
Fascinating stuff. But that incessantly repetitious "music" bed became downright maddening! Why do videos absolutely HAVE to have some kind of idiotic score under them to be deemed worthy of airing?
A small company in India without any funding is trying something unique on similar idea ...but not the same since 2018 ... but hey ... words
Do you mind sharing the link or name that company?
Are there any real pilots here who agree wholeheartedly with the claims? This looks like a promotional piece to me.
Too complicated and unreliable .
Read as "Official MAGA............."

Great, throw out all your control surfaces and your plane turns into a rock when the engine dies. Oh I get it, there's no pilot or passengers. It's cheap, simple weapons tech. Good job.
What a wasted effort, wasted money.
