An advantage of multirotor aircraft is the simpler rotor mechanics required for flight control. Unlike single- and double-rotor helicopters which use complex variable pitch rotors whose pitch varies as the blade rotates for flight stability and control, multirotors often use fixed-pitch blades; control of vehicle motion is achieved by varying ...
The Robinson R22 has a "teetering" cyclic design connected to a central column located between the two seats. Helicopters with fly-by-wire systems allow a cyclic-style controller to be mounted to the side of the pilot seat. The cyclic is used to control the main rotor in order to change the helicopter's direction of movement. In a hover, the ...
The original OH-6 Cayuse helicopter proved its worth during the Vietnam War in the light helicopter role. The designers at Hughes realized there was a market for a light multi-mission helicopter with an improved equipment fit than the OH-6 and Model 500M. The resulting design was the Model 500MD Defender which first flew in 1976
The first aerobatic manned drone, as this type of electrically powered multi-rotor helicopter is known, had 12 rotors and could carry 1-2 people. [37] Manned drones or eVTOL as they are called typically multirotor designs powered by batteries gained increasing popularity and designs in the 2020s. [38]
Future Vertical Lift (FVL) is a plan [1] to develop a family of military helicopters for the United States Armed Forces.Five different sizes of aircraft are to be developed, sharing common hardware such as sensors, avionics, engines, and countermeasures. [2]
The unique design enables maintainers to conduct all aircraft maintenance at the operational level. [ 11 ] The helicopter is propelled by two FADEC -controlled Pratt & Whitney Canada PT6 turboshaft engines, housed in separate engine turbine burst containment boxes, each with independent inputs to the main gearbox.

The TAI/AgustaWestland T129 ATAK is a twin-engine, tandem seat, multi-role, all-weather attack helicopter based on the Agusta A129 Mangusta platform. It was developed by Turkish Aerospace Industries (TAI) [1] in partnership with Leonardo S.p.A. [2] The helicopter is designed for armed reconnaissance and attack missions in hot and high environments and rough geography in both day and night ...
