Beginning of May 2018 MT-Propeller tested the new UNDUCTED PROP FAN, how MT likes to call the 7 bladed prop, on a Pilatus P-12 powered by a PT6A-67P. The flight tests showed that the 7-bladed prop reduces the noise level clearly and the performance tests showed very promising results. MT-Propeller is in technical talks with the turbine engine manufacturer for customizing the gear box to reduce the fuel consumption, to get the best out of the UNDUCTED PROP FAN.

Back in October 2016 MT-Propeller egineers and test pilots started flight testing the 7-bladed propeller on a Piper Cheyenne powered by the PT6A-135A turbines and the entire system performed with outstanding results. The endurance tests for certification were successfully performed on a turbine test bench for 3 months and 110 hrs.

All test bench tests inclusive flight testing have now accumulated more than 250 hrs of operation on the 7 bladed prop series.

MT-Propeller is working with high priority for the worldwide propeller certification. The first OEM has already ordered the 7 bladed propellers for a new project.

With more than 22,000 propellers systems and 74,000 blades in service, which have accumultated 150 millon flying hours, MT-Propeller will continue pushing the propeller powered airplanes. Worldwide, more than 210 STCs are available, 62 factory certified service center provide best service all over the world.

If you want your piston be smooth and low noise like a turbo prop and your turbo prop be smooth and sound like a jet, choose YOUR MT-Propeller.

MT-Propeller is the world leading natural composite propeller manufacturer with 30 certified propeller models from 2-blade to 7-blade hydraulically controlled variable pitch propeller, for engines producing up to 5000hp, and 2-blade to 4-blade electrically controlled variable pitch propeller, 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 and hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners.

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