Silent 7 MT-Propellers

Silent 7 - MT-Propellers


Just bringing the QFJ improvements, many customers enjoyed and experienced over the last 20 years, to another level with our latest designs.

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 ... and more STCs are planed

The 7-bladed propeller is pushing the new limits for certain applications to go beyond the achievement of the 5-bladed propellers.

The advantages of the Silent 7:

  • improved performance in take off, climb and cruise
  • a very low noise level inside the cabin as well as outside
  • a jet like sound
  • a very smooth run

The Pilatus PC-12 STC with the Silent 7 MT-Propeller is fullfilling the highest noise regulations in European countries for unrestricted airport operations.
