MT- PROPELLER
the industry standard for performance propellers
Significantly reduce noise inside and outside your aircraft while increasing the performance of your PC-12. More ground clearance for fewer FODs. Easy field installation with no engine modifications necessary, FAA Certified, and unlimited blade life.
7 BLADE
MT-PROPELLER
The Silent 7 is the world’s first 7-bladed prop for general aviation and defines a new level of comfort and performance never experienced on any turboprop aircraft before.
The world’s first 7-bladed Unducted Prop FAN MT-Propeller is now supplemental type certified on the Pilatus PC-12 powered by a Pratt & Whitney PT6A-67B or PT6A-67P propeller turbine. (PT6A-67P Engine Installation according to EASA STC 10065179 only applicable in EASA region).
When starting to develop the world’s first 7-bladed propeller for general aviation in 2016, MT-Propeller had the same vision as in the year 1999 when we came up with the first 5-bladed prop for turboprops. The 5-bladed prop became an industrial standard with more than 2500 propellers sold for various kinds of turboprops, and it is still an ongoing success story. The 7-bladed propeller is pushing the new limits for specific applications to go beyond the achievement of the 5-bladed propellers.
- Supplemental Type Certification (STC) from the FAA
- Best vibration-damping characteristics for almost vibration-free propeller operations
- Bonded on nickel alloy for best erosion protection of the blades
- No engine modifications necessary
- Certified Ground roll distance reduced by approx.10%; AFMS amended
- Certified Take-off distance over 50 ft obstacle reduced by approx. 15%; AFMS amended
- Climb performance improved
- Unlimited blade life
- More ground clearance for less FODs
- FOD repairable blades
- Significant inside and outside noise reductions
- Aircraft noise level is about 4 dB(A) less than with the original metal propeller
- Cabin noise is reduced by 6 to 7 dB(A) depending on location
- Comply with the strict German noise regulations 2010 — “Landeplatz Lärmschutz Verordnung” for unrestricted airport operations in Germany and other European Countries!
Due to the smaller diameter, the 7-bladed MT-Propeller for the Pilatus PC-12 has more ground clearance for less blade tip erosion and FODs.
