The United Engine Corporation has launched production of TV7-117V engines for the newest Mi-38 multi-purpose helicopter, as well as for the Ka-52 and Mi-28 attack helicopters. Previously, these rotorcrafts used engines made by Ukraine’s Motor Sich plant.

The decision to design and produce Russia’s own technology was made after the introduction of U.S. and EU sanctions and the complete rupture of military and technical cooperation between Russia and Ukraine in 2014. The original plan was to equip the latest Mi-38s with engines made by U.S. aerospace manufacturer Pratt & Whitney for supplies to Russia’s European and American partners.

The helicopter can carry out transport and landing tasks for the armed forces, oil and gas companies and search and rescue services. The Russian Helicopters design and manufacturing company has already received a series of orders from the Russian Ministry of Defense and commercial entities for the production of the new engine.

Dmitry Safonov, the Izvestia daily newspaper’s military correspondent, told RBTH that the TV7-117V engine ensures flight safety during operations in any weather conditions.

“It is able to achieve a force of 2,800 to 3,750 horsepower depending on the operating mode,” Safonov said. “The developer is currently designing around 200 engine modifications for different models of helicopters and airplanes.”

According to Safonov, this engine can be used in other helicopters weighing up to 15 tons.

The Klimov TV7-117 is a Russian fourth-generation turboprop engine developed in 1997 to power the Il-114 regional aircraft. The new engine features enhanced reliability, fuel economy and greater service life compared with its predecessors produced in the former Soviet Union. Its design is based on modules that may replaced under operation conditions. In 2002, Klimov introduced the TV7-117SM variant featuring a Full Authority Digital Electric Control (FADEC) as well as improved reliability, manufacturability and maintainability.

The TV7-117V is a turboshaft engine developed to power Russian rotary-wing aircraft that builds on the certified TV7-117 turboprop engine. Both engines share 90 percent of power plant components. the TV7-117V engine aim is to power the Mi-38 (TV7-117V and TV7-117VM), Mi-28 (TV7-117VK), and Ka-50/52 (TV7-117VK) helicopters and all modifications. The variants provided with the power take off shaft forward are known as TV7-117V/VM and with the power take off shaft backward TV7-117VK.

The TV7-117V design introduces emergency power (2,800 to 3,750 horse-power) for safe flight in extreme conditions and a new type of FADEC. The 30-second emergency power is 3,750-hp, 2.5-min is 3,500-hp and 30-min is 3,000-hp compared to 2,000-hp maximum continuous power. Source deagel.com

The engine’s turboprop versions can be mounted on the Ilyushin Il-114 and Il-112V planes.
