PERFORMANCE AND ADVANTAGES.
Thanks to a greater diameter and modern airfoils adopted on GT blades, tested in various flying conditions for years, many Yak 52 achieved outstanding performance compared to standard original blades :
- Greater static thrust.
- Shorter take off distance, both grass and hard surfaces.
(watch video)
- Higher cruise speed @ any power setting.
- @ 70% of power setting an average of 15 / 18 KMH / 8 /10 KTS faster. ( standard day )
- Shorter landings thanks to greater propeller diameter.
- More energy feeling during all aerobatic manoeuvres.
- Very good cooling in hot places.
- Reduced noise level both in the cockpit and outside.
- Smoother engine running.
- Lower fuel consumption.
- Both GT and V-530 blades reduced engine damage when propeller ground impact compared to blade made of aluminium or all composite.
