what allows a helicopter to fly forward,backward, and laterally? - correct answer -helicopters are equipped with a source of thrust -an engine produces power and delivers it to overhead and tail rotor via one or more transmissions and drive shafts two types of helicopter engines - correct answer -piston -turbine (offers more thrust per pound) define fuselage - correct answer the main body of a helicopter or plane define cowling - correct answer shaped metal skin that covers the en...

The four forces acting on helicopter in forward flight are...? correct answers Thrust, drag, weight, lift Bernoulli's Principle or the "venturi effect" correct answers As air flows over upper surface of airfoil, camber (curvature) of airfoil causes increase in speed of airflow which decreased pressure. Pressure is increased on bottom and this gives lift. Newtons Third Law of Motion and how it applies to helicopters correct answers "for every action there is an equal and opposite reacti...

Shaft b. Rotor c. Shroud ring d. Fixed blades e. Diaphragms c - correct answer The great majority of...

Helicopter Structure correct answers The typical structure of a helicopter is a fuselage (the body of the craft) with a mast protruding upward out of it. The engine of the craft drives power upward through the mast to the rotor blades, which are controlled by the pilot. This main rotor is used to generate thrust. This thrust is balanced by a second rotor, usually a tail rotor, which is intended to account for the effects of torque. In the USA, UK and Germany, it is conventional for the main roto...
