The Yak-40 flying laboratory, operated by the Siberian Aeronautical Research Institute (SibNIA) and named after S.A. Chaplygin, has successfully completed its maiden test flight using the VK-800 turboprop engine, developed by JSC "UZGA" (Ural Civil Aviation Plant).<br /><br />During the experimental flight, engineers evaluated the engine’s performance under various operating conditions. The aircraft remained airborne for approximately 15 minutes, reaching an altitude of 700 metres and a top speed of 340 km/h. According to the test engineers, the VK-800 operated stably throughout all phases — taxiing, take-off, cruising, and landing.<br /><br />Source and images: SibNIA | Telegram @AviaCT<br /><br />
