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 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.
The design featured two engines driving four rotors through a system of v belts. No tail rotor was needed and control was obtained by varying the thrust between rotors. [14] Flown many times from 1956, this helicopter proved the quadrotor design and it was also the first four-rotor helicopter to demonstrate successful forward flight.
This reduces rotor hub drag since there are no exposed linkages. A scaled model of an exhibition full-size mock-up of a single-rotor helicopter, proposed in 1912 by students of the IMTS headed by Boris Yuriev (1889-1957). No details of the mechanism are shown on the mock-up. Other swashplate and control design have been used.
Multi-rotor drones are inherently limited in speed and range compared to fixed-wing drones but have better control and manoeuvrability, including the ability to hover in flight.
A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau.
