Eurocopter EC-120B Colibri
Helicopter ES120 Colibri created to replace the successful family of helicopters AS350 Squirrel. When designing a new helicopter used modern technology, widely used in the construction of composite materials, the development of technology has a screw-in fenestron tail, thereby ES120 became in its class quietest helicopter.

The helicopter, which was named ES120 Colibri, was launched in 1990, when the French company "Aerospatiale" with CATIC (China National Import and Export Corporation of Aviation Technology) and "SingaporeTechnologiesAerospace" formed a joint venture to series production and development of promising 4-5-Local light helicopter.
The helicopter, which is able to meet the military and civilian customers, was named P120L. Design work started in February 1990, the first flight of the prototype planned for 1993, but the beginning of deliveries of machines in the series - on 1996.
Initially, the project single-engine helicopter P120L alleged use The four-rotor screw type Spheriflex development "Aerospatiale", screw-fenestron in the wake of reduced noise and easy ski gear. The design considered the use of a large number of composite materials from which the blades and the tail rotor, and a large part of the fuselage of the helicopter. It is expected that the replacement helicopters P120L AerospatialeLama and Gazelle helicopters and light to press the type Bell Jet Ranger on the world market. Emphasis is placed on a small noise and greater range.

In this project, initially leading role was in "Aerospatiale", which carried out the work 54 percent, whereas the share of CATIC was 30 percent, a "Singapore Technologies Aerospace" -16 percent. In October 1992 partners were able to sign a contract for a full-scale design of the helicopter.
Helicopter P 120L planned to be built in two versions: the "economic" base and improved for use at high altitudes and heat properties. In the process of designing the initial project has gone through significant changes, becoming more standard. Designers went to the decrease in maximum take-off weight of the helicopter at 500kg, carrying a three-blade propeller installed and made changes to the powerplant.
Project work completed, mainly to 1993. Then "Aerospatiale" has teamed up with the German company MBB, forming a group "Eurocopter", and helicopter P120L changed the designation on ES120 while undergoing further changes. The share of "Eurocopter" in the new version has to 61 umarnogo percentage of the volume of work, the share HAIC (Hafeyskaya Aviation Industry Company), owned by CATIC - 24 percent of the total amount of work, a for "Singapore Technologies Aerospace" left 15 percent. During final assembly, flight testing and certification of responsible European concern.

The plant of the company "Eurocopter" in the French city of Marignane built two prototypes. The first (F-WWPA) began to collect in the first half 1995, as he soared 09.06. 1995 years. Second (F-WWPD) prototype made its first flight 17.07.1996. Before the start of serial production of the helicopters passed tests for certification, including testing with the motor TurbomecaArrius2F, power 504l.s. and testing of the cold climate.
