Combustion in high pressure. I made this to explain to students why a jet has a compressor section before the combustion section.

The Problem of Aileron Effectiveness in a Stall
Lembra muito bem deste aeroporto de angoche, estava la de 1977 a 81.e muito lindo cidade da angoche ,conhesia minhas amigas mozambicanas otro trabalhava na supermercado. Mais deast que voltei na Tanzania nunca mais tivemos contacto ,mais gostaria uma veis vir la, e mostral meu filho donde nasseu. 06.08.24.
Excellent explanation!

could you tell me why the stall strip is before aileron in DA 20? Its quite unfounded to put it there as we want to have our aileron stalled last.

Hey this was an amazing job of explaining with both visual and verbal.
Thank you!
You saved my life, many thanks🔥🔥
I never heard the stall warning go off while landing. Is this only when there is no ILS? Because I also never heard the TAWS give a "too low, terrain, pull up" warning either during landings.
Grady: "There should be at least 1 stall every single flight..." Me: 😳 Grady: "And that during landing" Me: 😌
Awesome 👍
Nice idea ❤
Well explained video... 👍👍.....thanks a lot
Greetings! I have a quick question, I was looking over one of the aviation questions that asks, “ If the airspeed is increased from 110 knots to 150 knots during a level 45° banked turn, the load factor will...” At first I chose the load factor will increase as well as the stall speed. But the correct answer appears to be the load remain the same but the radius turn will increase. But at the above quiz question, I thought when you make a turn your load factor and stall speed will automatically increase? Or is it because the throttle is increased that’s why there’s no change in load factor and stall speed? Or that’s just say I don’t increase the throttle, and I make a turn, then in this case both the load factor and stall will increase? Thank you!
Hello, sorry it took me so long to respond. In a level turn the load factor depends only on bank angle, because load factor is lift divided by weight, and the more you bank an aircraft the more total lift you have to create in order for the vertical component of lift to still be equal to weight. It is a function of trigonometry, so in a level 60 degree banked turn you have a load factor of 2, your wings are creating twice as much lift as you have weight, and your stall speed will increase significantly with the increased load factor. The airspeed doesn't matter in terms of the load factor - in a sixty degree banked turn for example your load factor is 2 whether or not you are going 50 knots, or 250 knots, but as you correctly said, you turn radius at 250 knots would be much larger than at 50 knots. To generate enough lift to pull 2 G forces your angle of attack would also need to be much greater at 50 knots than at 250 knots. Does that answer your question?
Nice video, I've done this myself but instead of increasing the pressure with a pump, I just squeezed the bottle, similar results 😀
Useful. It would be nice and more accurate if your whiteboard sketches were oriented the same flow direction as the wind tunnel video.
It sounds like you are calling wing shape, "platform" as opposed to planform.
Stall speed is the lowest airspeed at which the aircraft is capable of supporting the aircraft's weight, whilst AT the critical AoA.
Well explained! Thank you very much.
Could you please make a video on delta wing and its effect on achievable min speed, max speed, lift to drag ratio and max sustained rate
Glorified referee's whistle LOL!!
can u explain how ailerons (?) work?
this is so helpful! I'm starting flight school (ppl) soon
Where did you find that old school FAA video? Link would be great. Thanks
Going to do this experiment tomorrow with first graders and I was looking for a simple explanation. This was the best one I've found, the drawing really helped! I hope I can explain the concepts well enough that they can understand, or at least make them curious for science. Thanks for the video!
I came from a guy sucking a Cessna to this. Very interesting
Good information.
