BASIC INFORMATION
The VK-800V, a 5th generation turboshaft engine (horsepower class 500-800 hp), is now being developed for small and medium-load helicopters with one or two engines (Ansat, Mi-54, Ka-126, Ka-226 and others).
The engine is currently being tested. Certification is expected in 2008.
PRODUCT QUALITY
Engineering excellence
The goal is to design a modern, reliable, lightweight, inexpensive and cost-efficient engine. The VK-800V is based on a well-known model involving a centrifugal compressor and uncooled single-stage turbines. This simple design will cut production and maintenance costs, while the excellent performance of individual components will translate into remarkable cost-effectiveness.
Universal platform
The VK-800 project involves the development of a turboprop model (VK-800S) for multi-purpose aircraft with 1000-1500 kg payload capacity.
FACTS
- To be installed on Ansat, Mi-54, Ka-126, Ka-226 and other helicopters.
- Certification is expected in 2008
- Power class – 500-800 hp
