The ECl20 helicopter was jointly developed by China, French and Singaporean. The project started at 1993.
ECl20 is a multipurpose light helicopter for 2 1 century, and its civilian type is called "hummingbird". This kind of helicopter is first-class in design. The spherical flexible main rotor with three high-performance composite blades and a new type of low-noise ducted tail rotor are equipped with reliable high-power engines and advanced electronic equipment. It has the characteristics of low fuel consumption, low noise, comfortable ride and low maintenance cost, and can be widely used in public security patrol, official transportation, general aviation, aviation medical transportation, training and other fields. It is one of the most advanced light helicopters in the world.
EC 120 helicopter has become the first choice for the new generation helicopter trainer of our army aviation because of its good take-off and landing, maneuverability and versatility. It has been put into use, which meets the needs of teaching and training of flight cadets of Army Aviation, and will play an important role in shortening the training period of flight personnel, improving the training quality and improving the combat effectiveness of Army Aviation.
The rotor system of aircraft consists of a spherical flexible hub, three blade rotors and a two-stage reduction gear transmission. 8-blade ducted tail rotor. The rated rotor speed is 406 rpm and the tail rotor speed is 4567 rpm. Sliding landing gear. Rotor blades, tail rotor blades, sled landing gear and most of the fuselage are composite structures, and the middle fuselage is metal structure. The ball flexible paddle and rotor shaft are composite kits. Equipped with anti-collision seat and fuel system. The first batch of 300 ECl20 aircraft are equipped with turboshaft engine TM 319 "AAGJE" of Tubomeka Company, with a single power of 376 kW and a transmission power of 330 kW. The total fuel quantity is 4 16 liter. It is possible to develop another type of PW 206 engine. 1 driver 4 passengers. The luggage compartment is located under the engine, flush with the cockpit floor, and the luggage can be reached from the cockpit. Equipped with side doors and back doors. Equipped with helicopter and engine fault display (VEMD), VEMD is a dual-redundancy 3-module data processing system, which can monitor performance and maintenance information using a glass screen.
