What are High Lift Devices? | Impact of High Lift Devices on an Aircraft Operation | Flaps & Slats
Hi. In this video we look at high lift devices installed on an aircraft wing. We focus on 2 high lift devices: Flaps and Slats. We see the operation of these devices in different configurations and the impact of these configurations on an aircraft.
We also look at the biggest concern when flying at low speeds: Stall. We see the variation of lift with the angle of attack and the variation of Stall Angle when flaps and slats are used.
Thank You!

Glad it was helpful!
Thanks for your awesome video! Compared with the trailing edge flap up configuration the maximum Angle of attack for the flaps down configuration is SMALLER! ❤

3:13 False. Extended flaps usually makes lower critical AOA (stall at lower AOA).

Wrong, you stall at the same aoa. Using flaps increases the angle of attack as the chord line has been modified, which makes you reach the critical aoa sooner or with less pitch.

@@Hk-uw8my nope. Thats why bigger planes use slats when flaps are lowered. Mostly not for lower speed, but to make same critical AOA. But yes, chord line is changed, but also shape - so calculating angle if incidence for this "new chord" is not useful - it will give little wrong data (stall aoa will be different than calculated in that way).

@@norbert.kiszka but the stall aoa is always the same. It's just a matter of how long you're gonna take to reach it , or how far will you pitch up. it might be easier to assume that you have a lower critical aoa if you want to make calculations but it doesn't change the fact that it is not the case. It is both the increase in camber and aoa that give more lift when trelling edge flaps are used. And since the aoa has been increased, what happens factually is that you will just reach the critical one sooner than without flaps. The leading edge slats are used to delay the stall from the moment as you are about to reach the critical aoa , which artificially increases the critical aoa, again to make things easier. But if we look closely it is not the case.

@@Hk-uw8my maybe You are confusing stall AOA with stall speed. With lowered flaps stall speed is lower (due to higher CL for same AOA) and stall aoa is lower.
Good

Are slats in every commercial aircraft?

In most of the aircraft, yes!
Flaps and slats trick the wind into thinking you have bigger wings. :D
