World's first 11-bladed propeller takes first flight

MT-Propeller Entwicklung GmbH has completed another world's first to explore the possibilities in propeller technology.

On a Piper PA31T1 equipped with P&W PT6A-135A turbine engines, the world's first 11-bladed propeller took the sky with an impressive noise and sound signature. The very promising results in static thrust, which demonstrated a 15% increase over the standard certified five-bladed propeller, and the jet-noise signature showed another time what could be possible in propeller developments. This propeller system combined with a low rpm power supply from a turbine or an electric engine opens new possibilities for performance, efficiency and noise.

MT-Propeller is the world leading natural composite propeller manufacturer with 30 propeller models from two-blade to seven-blade hydraulically controlled variable pitch propellers for engines producing up to 5,000hp, 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.

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 or hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners.

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

MT-Propeller is the holder of over 220 STCs worldwide and the OEM supplier for more than 90% of the European aircraft industry as well as 30% of the US aircraft industry. More than 28,000 propeller systems with over 90,000 blades are in service, and 180 million fleet hours have been performed on MT-Propellers. With the longest industry TBO of 4,500 hours or six years for the five-bladed turbo prop MT-Propeller has proven the reliability of its products over the years.
