Although precession is not a dominant force in rotary-wing aerodynamics, it must be reckoned with because turning rotor systems exhibit some of the characteristics of a gyro.

Rotary
An aircooled engine whose cylinders, arranged like the spokes of a wheel, rotate around a fixed crankshaft. The fuel is supplied to the engine through the crankshaft and the engine normally exhausts straight out the top of the cylinder.
ROTARY ENGINE - A powerplant that rotates on a stationary propeller shaft.
Rotary Engine: A radial aero-engine in which the crankshaft is stationary and the cylinders revolve, carrying the propeller on an extension.

ROTARY ENGINE - Cylinders disposed as for radial engine, but in this case the crankshaft is fixed, and cylinders and crankcase rotate around it.

You need a sharpie marker, a straight edge, a measuring device, and a good pair of scissors or a rotary cutter. When you make a cut, allowance for small deviations is usually built into the dimensions.
They are suited to rotary-wing applications because they have almost no center of pressure travel.
Robinson's R22 is the company's official rotary-wing trainer, but that's not to suggest that the R44 can't be used for teaching missions. Earlier this year, a Compton, Calif.
VFR operations: 30 minutes by day and 45 minutes by night for fixed wing and 20 minutes for rotary wing.
In rotary-wing aircraft, induced drag decreases with increased aircraft airspeed. The induced drag is the portion of the total aerodynamic force which is oriented in the direction opposing the movement of the airfoil.
We will pay special attention to rotary motion, since it is less familiar to most people than ordinary straight-line motion. Gyroscopes, in particular, behave very differently from ordinary non-spinning objects.
Helicopters are classified as rotorcraft or rotary-wing aircraft to distinguish them from fixed-wing aircraft because the helicopter derives its source of lift from the rotor blades rotating around a mast.
Primary Flight Control System: The most basic part of the flight controls operated by a pilot, including wheel (fixed wing), yoke (fixed wing), cyclic (rotary wing), pedals (fixed wing and rotary wing), throttle (fixed wing), ...
Hours flown per crew per month in MTOE rotary wing aircraft assigned in FORSCOM, USAREUR, USARPAC, EUSA, USARSO, ARNG, and USAR.
Parachute
A device used or intended to be used to retard the fall of a body or object through the air.
A flight control operated by moving left or right with hand in rotary-wing aircraft, primarily to control roll (heading); controls differential pitch of the rotors as they rotate from one side to the other on a rotary-wing aircraft; ...
Disk Term describing the shape of the rotary wing or propeller formed by the spinning blades.
In 1884 and 1892 he experimented with monoplane models, and in 1889 he constructed a rotary airplane engine, driven by compressed air.

touchdown zone - (1) For fixed wing aircraft, the first 3000 feet of runway, beginning at the threshold. (2) For rotary wings and vectored thrust aircraft, the portion of the helicopter landing area or runway used for landing.
Aircraft powered by turbine engines including turbojets and turboprops but excluding turbo-shaft, rotary-wing aircraft. Such aircraft normally use Jet-A fuel (AC 150/5200-33A).
Helicopters are classified as rotorcraft or rotary-wing aircraft in order to differentiate them from fixed-wing aircraft. While aircraft achieve lift from their wings, helicopters achieve lift with rotor blades which rotate around a mast.
