Japanese portable helicopter. In the unloaded state of the individual helicopter GEN H4 weighs only 70 kg, and the four motors of 10 horsepower allow him to fly at a speed of about 90 km/h.
The helicopter was developed in 1999, the Japanese company “GEN Corporation”, a subsidiary of the company “Engineering System”. Designed as a civil helicopter. The first flight was made in 2000. The helicopter is equipped with four light engines. The designers claim that the helicopter which comes-to-order unassembled, you can collect under the instructions independently for 30-40 hours.
Compact aircraft a long time do not give rest to designers all over the world. Reports on the development of single helicopters regularly appear in the press over the past decades. Doing this both military and civil aircraft. For example, in 2002, the Omsk space Association “Flight” have been successfully tested backpack assault helicopter “Yula”, developed in 1999. This helicopter is designed for strikes on ground targets and perform search and rescue operations.
However, to mass production, none of the developments never came. Another attempt to create a serial personal helicopter has taken the company GEN Corporation, created by Gennem Yanagisawa. The concept of the helicopter began to develop in the early 1980s, when Yanagisawa has created its own lightweight two-cylinder two-stroke engine volume of 125 cm3 and a power of 10 HP Because the engine power was small, the motor has been used in gliders and then in model helicopters.
