The geometrical twist of wings is characterized itself by:
Increasing the lift on the wing causes a change in the induced drag:
Increasing the angle of attack alpha > alpha cr causes:
What kind of rule is? "In the tunnel by which an air flows a product of cross-sectional area and an air velocity is constant S * v = const"
What kind of rule is? "In the tunnel by which an air flows, the sum of static and dynamic pressure is constant at every point of the movement"
To describe the movements of aircraft (airplane, helicopter, glider, etc.) in the space system is used three axes. How the vertical axis is marked?
