The world's first nine bladed prop started its flight test programme on March 11th 201, flying at 220 kias and 1700 rpm with maximum torque on a PT6A-135A turbine powered Cheyenne test aircraft. According to the developer MT-Propeller, the initial results are very promising and the function, handling and operation of the aircraft are like those props have already been in service 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 the design of the propeller driven airplane, top speeds of up to 430 ktas are realisable with such a installation, by reducing at the same time the fuel consumption to a turbo prop from a jet.

With this milestone MT-Propeller proves that the innovation in propeller driven airplanes is just at the beginning. Flying an airplane powered by props but with the comfort of a jet and the lowest fuel consumption is now attainable.

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 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.

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 210 STCs worldwide and the OEM supplier for more than 90% of the European aircraft industry as well as 30% of the US aircraft industry. 22,000 propeller systems with more than 74,000 blades are in service.

150 million fleet hours have already been performed on MT-Propellers. The first MT-Propeller was shipped 37 years ago.
