한국형 전투기 (KF-X) 첫 풍동시험 전 과정 첫공개! KFX 구조와 성능, 개발계획 등 KFX의 모든 것 소개하는 18분 짜리 풀영상 공개!
KF-X를 개발중인 한국항공우주산업이 한국항공우주연구원 저속풍동실험실에서 KF-X의 기체 형상 설계를 위한 풍동시험을 시작했습니다.
풍동시험에 쓰인 축소모형은 C105 형상을 13분의 1로 축소한 것이라고 하는데요
풍동시험 관련 내용은 풀영상을 참고하세요

Korean fighter (KF-X) The first wind tunnel tests before the first public course! KFX structure and performance, development plans, including full 18 minutes video to introduce the public to all KFX!
Is being developed by the Korea Aerospace Industries KF-X began wind tunnel testing for gas-shaped design of the KF-X low-speed wind tunnel at the Korea Aerospace Research Laboratory.
I’d spent a scale model wind tunnel testing would have reduced the C105 1 13 minutes into shape

Турбовальный двигатель ТВ7-117В (TV7-117V engine)

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

Universal platform

Two versions of the engine are produced:

  • with the power shaft in front – the TV7-117V/VM model for the Mi-38 helicopter and its versions;
  • with the power shaft in the rear – the TV7-117VK model for upgrading Mi-28 and Ka50/Ka52 helicopters.


  • To be installed on Mi-38 helicopters
  • Certification expected in 2009
  • Power class: 2500 – 3000 hp
