Rus­sia over­comes im­port de­pen­dence on he­li­copter en­gines

SP's MAI - - AEROSPACE DEVELOPMENTS -

The United En­gine Cor­po­ra­tion (UEC) has started a se­rial pro­duc­tion of new en­gines TV7-117V de­vel­oped by JSC ‘Klimov’ for he­li­copters Mi-38. Tur­bo­prop en­gine mod­i­fi­ca­tions can be also used on the air­craft IL-114 and IL-112V. The emer­gence of TV7-117V en­gines al­lows to carry out a com­plete im­port sub­sti­tu­tion of pro­duc­tion in this seg­ment.

“In terms of ef­fi­ciency, re­sources, re­li­a­bil­ity the en­gine is among the world’s top sam­ples in this class,” an­nounced the of­fi­cial UEC rep­re­sen­ta­tive Anas­ta­sia Denisova to Izves­tia. “By 2020 it is planned to pro­duce to­tally at least 200 dif­fer­ent mod­i­fi­ca­tions (for he­li­copters and planes). Ear­lier our en­gines for civil and mil­i­tary ve­hi­cles were made only in Ukraine. Now TV7-117V en­gines are made of de­tails and en­gine com­po­nents, that are en­tirely mas­tered in the coun­try. The pe­cu­liar­ity of TV7-117V en­gine fam­ily is to en­sure he­li­copter’s safety in ex­treme sit­u­a­tions.

“Be­fore 2020 we plan to re­lease more than 200 en­gines of TV7-117V en­gine fam­ily. To­day the cor­po­ra­tion has fully ex­panded the se­rial pro­duc­tion of en­gines TV7-117V.”

Ma­jor sup­plier of com­po­nents for the fi­nal en­gines’ as­sem­bly will be com­pa­nies that are part of UEC JSC ‘ V.V. Ch­erny­shev MME’, JSC ‘SPC Gas Tur­bine Salute’, as well as other en­ter­prises.

The de­vel­oper claims that TV7-117V is bet­ter than PW127T/S in al­most all char­ac­ter­is­tics: it has a higher power on mode, the best in­di­ca­tors of mass per­fec­tion and fuel econ­omy. In ad­di­tion, TV7-117V en­gine can op­er­ate in any cli­matic con­di­tions — in the trop­ics and in the Arc­tic. These ad­van­tages will en­sure Mi-38 an im­pres­sive ex­port po­ten­tial.
