When the shaft of the helicopter rotates, it creates a low pressure. Because of the low pressure, the helicopter lifts. Is my understanding that this is just an application of Bernoulli's theorem?

An airplane wing creates a faster air flow on the upper side and slower air flow on the lower side. Pressure of a gas and the speed of the gas molecules are directly related. If the speed of molecules ...

There is a grade-school explanation of how a wing works that goes approximately like this (although I'm leaving out an erroneous bit): Because of the geometry of the way the wing meets the air, air ...

I hope this is a physics topic. I thought it may be appropriate because of conservation of momentum. I was under the impression that lift in an airplane wing ( an airfoil ) was due to difference in ...

I learned, in grade school, that lift was generated via the particles on either side of the wing having to reach the other end at the same time. Looking back, that indeed has no physicality to it. So ...

I'm a computer scientist that likes to read about math and physics occasionally. A local author at a nearby aviation center brought bernoulli's flight equations into question. It was clear enough ...

At first I thought that the lift force of an airplane wing came from the buoyant force of the air. Thus we can calculate it's lift force using $$ F_b={\rho}gV$$ However, that does not seem to be ...

Why is the pressure on the inside of air flow curvature considered be low pressure and it is considered to be high pressure above? I read and seen videos that this is the case but I want to know why. ...

I read it somewhere on the internet that wings of an aeroplane are designed in such a way, that they increase the velocity of air above the wings and so pressure above the plane becomes less than the ...

One explanation I read: Because of the wing's geometry, the "upper" side of the wing is longer, so the air has to travel faster: My wondering: Who said (and what was his/her explanation) that air ...

Why is the flow above the wing faster than the lower one? Most people say it's because the pressure above is lesser than the bottom one But for the pressure to be low... The velocity must be high.So ...

I have heard part of the explanation and that is that air on the top part of the aircrafts wing wants to move in a straight line, but the air is pulled down the slope or camber, but that's as far as I ...

On aircraft wings, the bottom is flat and the top is curved. I know this benefits the aircraft by producing lift, but I wish to understand how. I'm told it has something to do with how fluids behave.

I am not here to continue any debate about what really allows airplanes to fly. Rather, what I am looking for is an informed, thoughtful, illuminating and self-contained explanation of Bernoulli's ...

I remember in the high school physics, my teacher told us that the design of the plane wing is because we want the air above the wing flowing faster than the air flowing below so the pressure above ...
