Летно-исследовательский институт имени М.М. Громова

Development of new technologies based on the Institute-conducted basic research holds the most ranking place in its scientific and practical activities. By now, the Institute has developed and put on the market the following products:
  • flight testing techniques - onboard trajectory measurement complex, flight test planning expert systems, methodology of new engines' testing using only flying laboratories, new principles of information and measurement systems' construction.

    “ Use of the GLL-31 and GLL-VK Flight Experimental Complexes the Institute is carrying out research into crucial problems of hypersonic flight, among which the following are the most important: - construction of an effective engine unit; - determination of an aircraft's aerodynamic configuration; - creation of heat-protective material and development of a structure of aircraft and engine heat-protection and etc.”

    The Institute produces up-to-date onboard measurement systems, including trajectory measurement systems.
    Among the available products are the following:
    • low- and high-frequency data collection and accumulation solid storage systems;
    • vibration parameters measuring devices ;
    • instant temperature sensors;
    • miniaturized flat piezoresistance beat and pressure distribution sensors;
    • hot-wire airflow velocity vector transducers and instrumentation for aerodynamic friction stress measurement.
    • aircraft performance improvement - mobile ramp, aeronavigation complex based on satellite technology, screw vibration reduction, aircraft operation on gas fuel, high reliability airborne communication, mid-air refuling automation;
    • Flight safety - ejection seat path control, icing shape calculation techniques, methods of reducing damage to an engine caused by foreign objects, aircraft protection from anti-air missiles, unified computerized training class, recovery technique for crash-damaged records of emergency recorders;
    In accordance to its status of a parent enterprise in charge of prototype flight testing, the Institute offers the following testing-support services to construction offices:
    • the testing airfield with a proper service package;
    • the airborne command and measurement post based on the II-76MD aircraft
    • for information support when testing manned, unmanned, and space objects - on long unequipped ranges;
    • advanced development of various issues of flight dynamics, engine units, - control systems, and instrumentation components using flying laboratories and flying models;
    • self-supported conduction of the most complex tests, such as critical flight modes, structural strength, flutter, assessment of flight control and navigation equipment and weapon system components,electromagnetic safety, etc.;
    • participation of the Institute's experts in aerospace machinery prototype testing, including certification;
    • use of the GLL-31 and GLL-VK Flight Experimental Complexes in carrying out research into crucial problems of hypersonic flight, among which the following are the most important:
    • construction of an effective engine unit;
      1. determination of an aircraft's aerodynamic configuration;
      2. creation of heat-protective material and development of a structure of aircraft and engine heat-protection;
      3. research into flight dynamics and construction of a control system. Traditionally, the Institute gives recommendations and exercises assessment of aircraft operational and performance characteristics.
