Aug 19,  · Aerodynamics of autorotation in forward flight Autorotative force in forward flight is produced in exactly the same manner as when the helicopter is descending vertically in still air. However, because forward speed changes the inflow of air up through the rotor disk, the driving region and stall region move toward the retreating side of the.

A relatively simple method of predicting the performance of a propeller (as well as fans or windmills) is the use of Blade Element Theory.

In this method the propeller is divided into a number of independent sections along the length. Principles of Helicopter Aerodynamics Second Edition The helicopter is truly a unique form of aircraft and a mastery of modern aeronau-tical engineering that fulfills a variety of civilian and military roles.

The understanding of low speed propeller aerodynamics was fairly complete by the s, but later requirements to handle more power in a smaller diameter have made the problem more complex.

Propeller research for National Advisory Committee for Aeronautics (NACA) was directed by William F. Durand from Most aerodynamic text books only give a brief view of propeller aerodynamics; however this book Propeller Aerodynamics delves more deeply into this subject.

A propeller, like an airplane wing, is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of a moving propeller on an airplane, the air pressure in front of the propeller is reduced, and the air pressure behind the propeller is increased.

A lateral rolling tendency which starts when the helicopter has one skid on the ground and it becomes a pivot point for lateral roll. Each helicopter has a critical rollover angle beyond which recovery is impossible. If the critical rollover angle is exceeded, the helicopter will roll over on its side regardless of cyclic corrections by the pilot.
