i believe it is going at a relatively slow speed. Not enough air is going over the foil to generate lift so it doesn’t need a steep angle of attack to stall.
at 0:53 in, I don't understand how a stall will "always occur at the same angle of attack regardless of airspeed..." ? I thought if you have enough power and airspeed you can almost go straight up, like jets do.
Hello, Do I understand it right that, Stall will happen when you have a large angle of attack at relative low speed? But if, with the Same Angle of Attack, the speed is much higher, then stall won't happen. Right? And the plane will climb up of course. Right? If right, What are those speeds and angle of attacks? If not right, Then how come that fighter jets and other acrobatic planes can climb strait vertically? I suppose this is because of their high speed, which provides enough lift, no matter in what direction they move. So why can't normal plans in a critical angle of attack give full throttle to gain more lift?
It's airflow. Jets fighters are different. So the wing won't stall of the airflow is not hitting it from a different angle. As the jet goes fast, and it's the engine pushing it. Makes a difference
Hiya! I've just started my PPL training and I've done a couple lessons on stalls. Here's what I've picked up: So like it says in the video, a stall can still happen at high speeds. It really is due to the angle of attack and how the airflow separates as shown by the airtunnel visual. When the air is turbulent and doesn't flow smoothly over the wing it cannot create lift as it normally does. Also the angle of attack is defined as the angle between the relative airflow and the chord line of the wing. This means that if there is a sudden gust of wind it could cause the aircraft to stall. Fighter jets and acrobatic planes have enough power in their engines to climb without the help of the lift produced by the wings (you'll notice how these aircraft often have less camber to their wings as they do not need an aerofoil to produce so much lift). In a smaller plane as demonstrated in the video, even at full power the engine cannot pull the plane vertically through the air. The only way it can produce enough lift to keep it in the air is through the lift from the wings. So once the critical angle is reached (usually ~ 15°) the amount of lift produced by the wings becomes smaller than the weight of the plane and it begins to drop.
@@Ricardinyo1 OK. If I understand it right then, stall happens because the flight path is not exactly the same as the pitch and the nose of the plane. Therefore the angel of attack increases. But if a plane can climb exactly in the direction of its nose, then stall won't happen. Right?
the noise pollution from the constant low-level flights from noisy airplanes from embry-riddle over the same areas all day long is criminal and daytona and the mayor won't do anything about it :(
Great explanation, I came here to know how stalls happens and I learnt more about the angle of attack!
I must say, I feel way more comfortable with an aircraft stall after watching this video
THank you for the explanation, it's easy to understand!
It seems like the Cessna, at 0:55 in, doesn't seem to be climbing too steeply but it still stalls?

Need some more video it’s very helpful

Right?
Fantastic instruction
And how exactly the nacelle chine works?
what are the causes of turbulent flow?
Super explained , sir

Shouldn't have moved there, literally your own fault
