MT-Propeller has received STC from EASA for the five-blade Quiet Fan Jet MTV-27 composite propeller on the Quest Aircraft Design Kodiak 100 series with Aerocet 6650 floats powered by a Pratt & Whitney PT6A-34 propeller turbine. The FAA STC is in progress.
MT-Propeller VP Martin Albrecht says, that the installation feature the following advantages: a takeoff improvement of 20 per cent; no propeller speed restrictions on ground while operating in low idle; lower ITTs during start-up for less engine wear; significant cabin noise of up to 5 dB(A) and vibration reduction; aesthetic ramp appeal; compliance with the strict German 2010 Landeplatz Lärmschutz Verordnung noise regulations for unrestricted airport operations in Germany and other European countries; and a maximum RPM reduction to 2,000 RPM with increased torque for 750 shp.
Due to its smaller diameter, the MT-Propeller when compared to the original metal propeller for the Kodiak 100 series has more ground clearance for less blade tip erosion and FODs. The natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of a 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.
