TO Multirole Twin-Engine Aircraft

Another plane intended to transport passengers, the 101N project is also another twin-boom twin-engine, but the short rectangular wing of the 101M is replaced by a tapered wing of higher aspect ratio; the power unit consists of two TVD-1500 turboprops rated at 957 kW (1,300 ch-e).

The 101N is a commuter aircraft designed to hold nineteen passen­gers, but different cabin layouts can accommodate mixed cargo, all cargo up to 1,700 kg (3,750 pounds), training for civil aviation schools, ambulance runs, parachute drops, and other transport roles. The air­craft can be equipped with special systems such as 360-degree scanning radar, rotating infrared and ultraviolet radiometers, thermal sights, and cameras for various missions: around-the-clock, all-weather maritime surveillance (including over the 200-nautical-miles zone); ecological sur-

veillance; maritime search-and-rescue (plus survival kits can be dropped by parachute); shoal mapping, or forest fire surveillance.

The aircraft can be operated in adverse weather conditions, in cold climates, and on unpaved strip whose strength is at least 6 kg/cm2 (85.3 pounds per square inch). The aircraft’s APU starts the engines and provides the necessary power for some on-board systems, the load­ing and unloading devices, and the cockpit’s heat when the plane is on the ground. Like the 101M, the 101N can be equipped with floats or skis.
