FAA OKs the Silent 7 MT-Propeller on the PC-12 Series

Atting, April 2021

World's first 7-bladed Propeller for General Aviation is now supplemental type certified by FAA STC SA02742NY on the Pilatus PC-12 powered by a Pratt & Whitney P&C PT6A-67B or PT6A-67P propeller turbine.
(PT6A-67P Engine Installation according to EASA STC 10065179 (FAA STC SA02266LA) ).

The Silent 7 defines a new level of comfort, performance, so far never experienced on any turboprop aircraft before.

When starting developing the world's first 7-bladed propeller for general aviation in 2016 MT-Propeller had the same vision like in year 1999 when we came up with the first 5-bladed prop for turbo props. The 5-bladed prop became an industrial standard with more than 2500 propeller sold for various kinds of turbo props and it is still an ongoing success story. The 7-bladed propeller is pushing the new limits for certain applications to go beyond the achievement of the 5-bladed propellers.

The Silent 7 is already supplemental type certified on the PC12 by EASA STC 10014953 R3.

MT-Propeller Vice President Martin Albrecht says that the installation of the 7-bladed MT-Propeller on the propeller turbine driven aircraft PC-12 features the following advantages:

• 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
• 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.

The MT-Propeller natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of an FOD.
They also provide best vibration damping characteristics for almost vibration free propeller operation and have bonded on nickel alloy leading edges for superior erosion protection of the blades.

MT-Propeller is the world leading natural composite propeller manufacturer with 30 certified propeller models from 2-blade to 7-blade hydraulically controlled variable pitch propeller, for engines producing up to 5000hp, and 2-blade to 4-blade electrically controlled variable pitch propeller, for engines producing up to 350hp as well as two blade fixed pitch propellers.

The high performance, light weight and durable MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels and hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners.

Fulfilling the highest certification requirements they are also supplemental type certified on Part 25 aircraft.

MT-Propeller is holder of over 220 STCs worldwide and OEM supplier for more than 90% of the European Aircraft Industry as well as 30% of the US Aircraft Industry. More than 25,000 propeller systems with more than 85,000 blades are in service.

World's first 7-bladed MT-Propeller - The Silent 7 - 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 (FAA STC SA02266LA) only applicable in EASA region).

When starting developing the world's first 7-bladed propeller for general aviation in 2016 MT-Propeller had the same vision like in year 1999 when we came up with the first 5-bladed prop for turbo props. The 5-bladed prop became an industrial standard with more than 2500 propeller sold for various kinds of turbo props and it is still an ongoing success story. The 7-bladed propeller is pushing the new limits for certain applications to go beyond the achievement of the 5-bladed propellers.

The FAA STC is in progress.

MT-Propeller Vice President Martin Albrecht says that the installation of the brand new 7-bladed MT-Propeller on the propeller turbine driven aircraft PC-12 features the following advantages:

• 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
• 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.
The MT-Propeller natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of an FOD.
They also provide best vibration damping characteristics for almost vibration free propeller operation and have bonded on nickel alloy leading edges for superior erosion protection of the blades.

MT-Propeller is the world leading natural composite propeller manufacturer with 30 certified propeller models from 2-blade to 7-blade hydraulically controlled variable pitch propeller, for engines producing up to 5000hp, and 2-blade to 4-blade electrically controlled variable pitch propeller, for engines producing up to 350hp as well as two blade fixed pitch propellers.

The high performance, light weight and durable MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels and hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners.

Fulfilling the highest certification requirements they are also supplemental type certified on Part 25 aircraft.

MT-Propeller is holder of over 220 STCs worldwide and OEM supplier for more than 90% of the European Aircraft Industry as well as 30% of the US Aircraft Industry. More than 25,000 propeller systems with more than 80,000 blades are in service.

Worlds first 9 bladed prop started the flight test program

Atting, March 19

Worlds first 9 bladed prop started the flight test program on March 11th 2019 and initial results are very promising.

Function, handling and operation of the aircraft is like those props have been in service already for years.

This new development is made for low noise, high performance future airplanes driven by electric powered engines, turbine engines or geared piston engines for propellers with low RPM.

Depending on propeller driven airplane designs, top speeds of up to 430 KTAS are realizable with such a installation, by reducing at the same time the fuel consumption to a turbo prop from a jet.

MT-Propeller proves with this milestone that the innovation in propeller driven airplanes is just at the beginning.

Flying a Jet comfort airplane powered by props combined with the lowest fuel consumption becomes a near future.
