Encyclopedia - Robinson R22

The Robinson R22 is one of the most successful helicopters in production today, serving as training, law enforcement, livestock mustering, pipeline patrolling and general aviation platforms. With its large windows and cheap operating costs, the Robinson R22 is an excellent choice in the light helicopter market.

Designed by Frank Robinson in 1973, the Robinson R22 made its first flight on 28 August 1975 and has been in production since October 1979. Powered by a 93kW (124 hp) Lycoming engine, it drives a semi-rigid two-bladed main rotor. No hydraulic assistance is available, and combined with the low-inertia rotor system it gives a very light feel on the controls. Fitted with skids, the Robinson R22 can also be fitted with floats as the Mariner version. The fuselage is of a chromoly steel construction, covered by aluminium and fibreglass.

To date, more than 3,600 Robinson R22's have been built.
