Enstrom 480B
The Enstrom 480 is a small, light helicopter produced by the Enstrom Helicopter Corporation. The 480 fuselage consists of a welded steel-tube framework with an aluminium cover and tailcone. The pilot controls the aircraft from the left seat, which is unusual for helicopters. The aircraft does not have a hydraulic system; a trim system absorbs rotor feedback and allows the pilot to position the desired stick setting. The 480B engine is capable of producing 420 shp, but in this application, it is derated to 305 shp for 5 minutes and 277 continuous shp, which is available to 13,000 MSL on a standard day. Thus hot-temperature or high-altitude operations have a considerable degree of power available. The engine drives a three-bladed rotor of 32 feet diameter and a tail rotor of 5 feet diameter. The main rotor and hubs weigh a total of 300 pounds, so there is considerable inertia in the system during a loss of power. Autorotation landings are uneventful.
