A helicopter is
A type of rotorcraft
Helicopter turbine engines produce ___________ thrust per pound than piston engines
More
The four main forces working on a helicopter are
Lift, weight, thrust, drag
Helicopters typically have between ___ and ___ main rotor blades
2 and 6
Depending on the type of helicopter, main rotor system components can include
A stabilizer bar, upper/lower swashplates, counterweights, pitch horns, teeter/coning
hinges, blade grips, pitch/scissor links, control rods
The function of the flybar is
To decrease crosswind thrust on the blades and enhance flight stability by keeping the

Thrust acts _____ to the aircraft's _____
Parallel, longitudinal axis
Profile drag consists of
Profile drag is usually defined as the sum of form drag(Shape of the object) and skin
friction(imperfections)
Vortices produced by spinning rotor blades create
Induced drag
When plotted on a graph, L/DMAX is the point where the helicopter's _____
Total lift-to-drag ration is the greatest
A helicopter's potential energy is affected by
The aircraft's height above the ground
