TsAGI transonic wind tunnel at the request of JSC OKB Crystal completed a cycle of research on the system of turboprop emergency generator (TVAG) for the SSJ-New aircraft, the press service said TsAGI.

The TVAG is designed to generate the electricity needed to supply first category consumers in the event of a failure of the main power supply system of the aircraft in flight. Installations of this type are essential for all modern civil aircraft.

For the tests we designed and built a stand for the installation of TANK in the working part of the wind tunnel. The tests were to verify the performance of TANK throughout the entire speed and altitude range of the aircraft. The issues of time and safety of the installation release, as well as the possibility to realize the maximum electric power at all operating speeds, including the minimum flight speeds were studied. In order to meet the altitude conditions the possibilities of pumping and vacuumization of the wind tunnel circuit were used. In this way, a flight altitude of up to 12 km from the ground was simulated.

“As a result of the tests, specialists of the Kristall design bureau together with TsAGI scientists confirmed the design solutions incorporated in the design of the TVAG, as well as the implementation of its design parameters,” said the head of the design department of JSC OKB Kristall Mikhail Gankin.

“The practical experience gained during such experiments will be taken into account in the future. These tests confirm TsAGI’s competence not only in scientific research, but also in certification of full-scale elements of aircraft in wind tunnels,” said Pyotr Savin, candidate of technical sciences and head of the laboratory of the Aerodynamics of Aircraft Centre at TsAGI.
