ROTARY WING
A helicopter;
ROTATIONS PER MINUTE (RPM)
A unit of measure for such things as engine speed.
a rotary wing aircraft intermediate in type, hereinafter referred to as "Gyrodyne", between a rotaplane (with the rotor free for autorotation and an upward total axial flow through the rotor disc), on the one hand, ...
The ability of a rotary wing aircraft to land safely without engine power. This maneuver uses the stored energy in the rotor blades to produce lift at the end of decent, allowing the model to land safely.
Auto Rudder ...
VFR operations: 30 minutes by day and 45 minutes by night for fixed wing and 20 minutes for rotary wing.
Rotary Wing Planform
Common terms used to describe the helicopter rotor system are shown here. Although there is some variation in systems between different aircraft, the terms shown are generally accepted by most manufacturers.
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), ...
AUTOGYRO - An aircraft with an unpowered rotary wing, which autorotates as the machine is propelled through the air by a conventional power plant. "Autogiro" is the trade name for autogyros developed by Juan de la Cierva.
...
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.
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), and collective (rotary wing); ...
another reason the hellicopters can't fly faster: At a certain speed the airflow does not pass anymore vertically through the main prop, therefore the rotary wing acts only as a wing, ...
Disk Term describing the shape of the rotary wing or propeller formed by the spinning blades.
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.
Autogyro development ceased before World War II, and with few exceptions, has not benefited from modern rotary wing advances applied to helicopters. When improvements in helicopters made them practical, autogyros became largely neglected.
moves along the chord line when angle of attack changes, because the two vectors are separated. This characteristic of nonsymmetrical airfoils results in undesirable control forces that must be compensated for if the airfoil is used in rotary wing ...
