- Shikadi 7y agoAh, thanks! Yeah that makes a lot more sense
- Tuxer 7y agoIf we're in nitpick land, it truly is important (especially in that 737 case) to remember that stalls on wings has nothing to do with speed, and everything to do with angle of attack (the angle between the wing and the apparent wind). Now, to be fair, going faster DOES create apparent wind coming from the front, so it decreases your angle of attack, but that's it. (the sensor that failed on the 737s was the angle of attack indicator, trying to estimate if the wing was going to stall).
- JorgeGT 7y agoWell, both are basically the same physical phenomenon: too much adverse pressure gradient leading to flow detachment from the airfoil, either the wing airfoil or the compressor blade airfoil.
