Technodinamika has developed a power pack for prospective air-transport aviation

Rostec State Corporation affiliate Holding Technodinamika has developped high-speed synchronous generators GSR-90/120 prototypes for a prospective aircraft with a hire electric power consumption feature.

"The serial production of generators like GSR-90/120 will significantly contribute to the reduction of the Russian aircraft industry dependence on foreign components," - said Igor Nasenkov, Technodinamika General Manager."In the long run, such power plants may be installed on a wide range of aircraft, from MC-21 and wide-body long-haul liners in civil aviation to transport aircraft."

Currently, Technodinamika is completing the GSR-90/120 prototypes preparation for full-scale testing, including functional, mechanical and thermal tests. The technical solutions applied will make it possible to create a product line of a smaller or larger variety depending on the need and power generation capacity.

A distinctive feature of the generator is the possibility of its use on board an aircraft without a constant speed drive in a range from 10800 to 24000 rpm. The generator GSR90 / 120 nominal power over the entire range of rotation frequencies is 120 kVA, the maximum power (within 5 s) is 180 kVA.

The GSR-90/120 synchronous generator has been designed for use as the main 115 / 200V electricity source in on-board three-phase alternating current systems with a frequency, varying from 360 to 800 Hz.

The generator is being developped out under the supervision of Valery Kaliy, the design bureau director and chief designer of the Technodinamika affiliate Ufa Aggregate Production Association, in the context of implementing a more electrically-intensive aircraft concept.
