The aircraft engine TV7-117V developed by the St. Petersburg-based enterprise UEC Klimov of the United Engine Corporation, which was designed for Mi-38 helicopters, has successfully proved its operability.
During the tests, the engine worked in continuous and alternating icing conditions in all operating modes, at heights of up to 4000 meters, at temperatures as low as minus 30 degrees Celsius.
As a result, confirmation of the possibility of efficient engine operation was obtained. This greatly expands the possibilities of operating helicopters. It is planned to obtain approval of the main modification from the Russian Air Register after completing the documents in the third quarter of 2019.
Testing the aircraft to perform operations under icing conditions is a prerequisite from the point of view of aviation regulations. Icing of an aircraft in clouds greatly affects the design characteristics which were formed by the engineering designers.
The TV7-117V turboshaft engine with a free turbine is designed and mass-produced at the UEC Klimov. The constructive design, electronic systems of automatic control and monitoring with full responsibility of the FADEC type provides high power with low fuel consumption and increased flight reliability. There are no analogues in fuel efficiency and take-off power in this class of engines.
The main technical characteristics of the TV7-117V: power on take-off mode – 2800h.p. (in emergency mode - 3140 h.p.), specific fuel consumption - 205 g / h.p. per hour, dry weight - 435 kg, the assigned life span of the main parts according to the resource management system - 2110 flight cycles.
