New Blades Provide Improved Cruise Speed, Faster
Aero-News has learned
that Italy's GT Propellers has finished testing its new wood and
composite-bladed propeller specially designed for Russian Vedeyneev
M-14 engines, commonly seen on Yak aerobatic aircraft.
The new two-blade propeller features a slightly increased
diameter over standard propellers, with scimitar tips the company
says help decrease noise noticeably, both inside and outside the
Representatives with GT Propellers told ANN this week that the
new blades have been tested on a Yak-52 and Yak-52TW. The company
is still conducting tests on Yak 18, 50 and 55 applications.
So far, the results have been encouraging. Here are the figures
cited by GT Propeller:
- Increased cruise speed at 62 percent power, from 108 kts to 118
- Faster acceleration times, resulting in a 150-ft shorter
takeoff distance on grass
- Reduced hourly fuel burn at 62 percent, 74 percent and full
- Cleaner dive penetration, at 200 kts.
The new blades are available in custom finishes and sizes,
ranging from 98 inches to 104 inches in diameter. An upgraded blade
retention system is available from the company for M-14 engines
producing more than 360 hp.
A matching composite spinner and new scimitar blade design are
also in the works, according to GT Propeller.
