Comprehensive advanced and maintenance research of newly constructed engines, engine systems, and auxiliary engine units is performed using multipurpose flying labs based on the production aircraft II-76, An-12, etc.
“The unique technique of determining stall characteristics was developed, including deep stall of heavyweight transport aircraft at Mach numbers equal to the actual ones and large Reynolds numbers, involving large-scale models. ”
Flight tests and research of prototype and production systems of satellite and long-range navigation, inertial instruments, as well as development of new techniques and methods for flight-testing flight control and navigation equipment, are conducted aboard the II-76MD multipurpose flying laboratory.
For concept development of a unified system of communication,
navigation and observation in accordance with the ICAO's construct, the
multipurpose An-72-based flying lab is used. The An-26K and Tu-134UBL
flying laboratories are used to flight-test new airborne weapon systems.
The An-12BK multipurpose flying laboratory equipped with the experimental
movable cockpit in the fuselage stern allows testing emergency escape
means - ejection systems and parachutes.
Aboard the MiG-25U flying lab, research
and tests of dynamics and high-altitude stabilization of the K-36 ejection
seat family are carried out. Since 1978 the Institute has been conducting
advanced flight research into critical flight behaviors with the aid of
dynamically similar free-flight models. The unique technique of determining
stall characteristics was developed, including deep stall of heavyweight
transport aircraft at Mach numbers equal to the actual ones and large
Reynolds numbers, involving large-scale models. This technique helped
to dramatically reduce complexity and cost of model research maintaining
at the same time high reliability of the obtained data. . <
