The TV7-117ST-01 turboprop engine developed by ODK-Klimov has passed a set of tests that simulated conditions as close as possible to flight conditions. This was reported in the press service of the United Engine Corporation.
The upgraded propulsion system for IL-114-300 includes a boosted turboprop engine TV7-117ST-01, AV-112-114 propeller with RSV-34S-114 propeller regulator, FADEC-type automatic control system (ACS) BARK-65STM and fuel system units NR-65SM, NP-65, AZRT-65. The type certificate for the TV7-117ST-01 engine was issued in January 2023.
According to the press service representative, before certification it is necessary to pass a set of tests, including bench certification and resource tests in ODK-Klimov, as well as special tests in CIAM, which include checks in a thermal barocamera, for resistance to ingress of foreign objects, such as birds or hail. Individual engine components underwent autonomous fire tests and external impact tests.
Flight tests of the engine were conducted as part of the IL-76LL flying laboratory. The tests lasted for four years, the flight time under the wing of the LL was about 120 hours. One of the results of these tests was confirmation of reliable operation of TV7-117ST-01 and AV-112-114 propeller with RSV-34S-114 propeller regulator.
The tests in the thermobarochamber lasted for two years. During them, the engine was simulated under conditions as close as possible to flight conditions – altitude, ambient air temperature and speed.
ODK-Klimov continues to perform certification work to expand the engine’s performance characteristics, as well as to certify the TV7-117ST-02 engine version for use as part of the powerplant of the TVRS-44 Ladoga aircraft.
