Aerodynamics is the branch of fluid mechanics that studies the motion of air, particularly when affected by a solid object. It is a core part of science and engineering, from cars, aircraft, and engines, to buildings and bridges, to atmospheric science, sports science, and even throughout biology. Join the discussions, share your questions, and learn more about aerodynamics.

I know that mechanical advantage is the conversion of same power to a lower working velocity and thereby higher force. I have always wondered how airplane engines with lesser combined thrust than the plane's weight can generate lift more than that. And I suspect it is the same mechanical advantage that is working here, where the engine puts out air with lesser force and higher velocity, in turn lifting the plane with higher force and lesser vertical velocity conserving the power after all kind of losses.
If this assumption as I suspect is correct (even though chatGPT says otherwise), can anyo ..read more

If the pressure above a slip line is slightly lower than the pressure below the slip line, how would we adjust the guess of the orientation of the slip line? I assume that you would just increase the angle of the slip line in small increments until the pressure above and below the slip line are close enough to each other. Thoughts?

I am deeply concerned that the "school of aerodynamics" is founded on invalid scientific principles:
The applicability of Bernoulli's Principle to aerodynamics.
The incompressibility of air below Mach 0.3.
The existence of Prandtl's no-slip boundary in air.
The applicability of Kelvin's theory of the conservation of circulation (requires incompressible fluid and conservative forces)
etc., etc., etc.
Since Einstein, Bohr, Rutherford, Planck etc., physicists have been understandably seduced by the excitement of QM, cosmology, black holes, superconductivity, particle physics, etc. and have aba ..read more

Where can I find something that can read values such as pressure and speed for a car wing in the cheapest and easiest way? Can anyone who has used something like this help? (Pitot Tube, pressure sensor)

I've been trying to figure this out for a few days now. I've drawn isobars on forward and aft swept wings and this is what they are supposed to look like going by the books. I read an explanation that said that unlike an infinite sheared wing, the finite wing has kinks at the root and tip which is assume are discontinuities. But they did not explain what the kinks did to the flow to make the issobars curve this way.
Why is it that at the Tip of the Aft swept wing the isobar curves forward but at the Tip of the Forward swept wing it curves backward? (Same issue with the root)
Or am I comp ..read more
