Germany-based manufacturer MT-Propeller Entwicklung has received EASA STC 10069627 for the Quiet Fan Jet composite propeller MTV-27-1-E-C-F-R(P)/CFR240-55( ) on the Quest Kodiak 100 series. Application for the FAA STC is in progress.

Vice president Martin Albrecht says that the installation features a number of advantages, namely: take-off improvement by 20 per cent; no propeller speed restrictions on ground while operating in low idle; lower ITT temperatures during start-up for less engine wear; significant cabin noise [up to five dB(A)] and vibration reduction; unbeatable 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 maximum rpm reduction to 2,000 rpm with increased torque for 750 shp.

Due to its smaller diameter, the MT-Propeller for the Kodiak 100 series has more ground clearance for less blade tip erosion and foreign object damage (FOD). The natural composite blades provide significant inside and outside noise reduction. They have no life limitation and are repairable in case of an FOD, they 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 produces 30 propeller models, from two-blade to seven-blade hydraulically controlled variable pitch propellers for engines producing up to 5000hp, and two-blade to four-blade electrically controlled variable pitch propellers for engines producing up to 350hp as well as two blade fixed pitch propellers. They are high performance, light weight and durable and can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels and hovercraft. In fact they can be developed for nearly every aircraft type from motor gliders to regional airliners. They are also supplemental type certified on Part 25 aircraft.

MT-Propeller is the holder of over 210 STCs worldwide and the OEM supplier for more than 90 per cent of the European aircraft industry as well as 30 per cent of the US aircraft industry. Currently, 22,000 propeller systems with more than 74,000 blades are in service. The first MT-Propeller was shipped 37 years ago and 150 million fleet hours have already been performed.

A factory certified network of 62 service centres provides service and maintenance all over the world.
