Atting, November 2017
Cessna P210N Silver Eagle with 5-blade MTV-5 MT-Propeller Entwicklung GmbH has received the FAA STC SA3976NY for the next generation 5-blade Quiet Fan Jet scimitar composite propeller MTV-5-1-D-C-F-R(A)/CFR210-56 on the Cessna P210N Silver Eagle equipped with a Rolls Royce 250-B17F/2 turbine (Modified as per LBA STC 0779/625b and FAA STC SA1003NE).
The installation is already certified by EASA STC 10060053.

MT-Propeller Vice President Martin Albrecht says, that the installation

  • reduces ground roll & takeoff distance over 50 ft obstacle by more than 15%
  • enhances climb performance by 4%
  • provides a jet like noise and vibration level
  • has approx. 3,7 kg (8,1 lb) less weight than the original 3-blade metal propeller
  • complies with strict German noise regulations 2010
  • improves the ramp appeal of the aircraft

Due to the smaller diameter, the 5-blade MT-Propeller has more ground clearance for less blade tip erosion.
The MT-Propeller natural composite blades provide significant inside and outside noise reduction.
They have no life limitation and are repairable in case of an 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.

MT-Propeller announces new FAA STC for the high performance  5-bladed QFJ Propeller MTV-27 on the Honeywell powered Cessna 208 Supervan.
   

Atting, January 2017
Cessna 208 Supervan with 5-blade MTV-27 Performance improvement for the Cessna 208 Supervan is easy now with the new 5-bladed MT-Propeller.
The MTV-27 Propeller, called the Quiet Fan Jet Propeller, takes the skydiving enthusiasts up in the air with a lot of new features, which can only be provided by a natural composite 5-blade Propeller.

MT-Propeller President Gerd Muehlbauer says, that due to the best damping characteristics of the natural composite MT-Propeller blades, vibration is reduced up to incredible 60% on aircraft fuselage, reducing maintenance cost compared to 4-bladed prop. The light weight MT-Propeller blades reduces the weight of the original OEM propeller by approximately 31 lbs.. Due to the reduced moment of inertia the wear on the starter and battery is also reduced and cooler engine starts are the result.

The extensive certification flight tests have shown, that the high tech engineering computer technology used in the MT-Propeller design department, has delivered a blade profile, which is not just aesthetically, it also improves the overall performance. Ground roll is reduced by 10%, which are approximately 162ft, climb performance is improved by 5-8% and a speed is increased by 2-3 KTAS.

The ongoing engineering research at MT developed a propeller, which reduced the inside and outside noise significantly and all models of the Cessna 208 Supervan series comply with the strict European noise regulations. Due to the smaller diameter ground clearance is increased for less blade tip erosion and the scimitar blade design has an unbeatable ramp appeal. Bonded on nickel alloy leading edges provide superior erosion protection of the blades in all weather conditions. Like all MT-Propeller naturally composite blades, the blades of the MTV-27 have no life limitation and can even be repaired in case of a ground strike.

The installation is already certified by EASA STC 10054488 with a lot of happy customers around Europe and now available for all US customers with FAA STC SA03850NY.

FIRST 7-bladed composite full feathering reversing propeller on a General Aviation Airplane designed, flight tested and now starting the endurance certification testing on a turbine test bench.

Atting, January 2017

New MT-sevenblade Prop


MT-Propeller - more than 35 years of Innovation.

  • first electric certified Constant Speed Propeller installed on General Aviation Airplanes
  • first electric-hydraulic reversing propeller certified on General Aviation Airplanes like the C206/ Husky A1, Lake …
  • first 5 bladed composite prop for General Aviation Airplanes on- TBM-, PC12, KA, C425, PA31T, Metro ...

All this has become an industry standard.

NOW - FIRST 7-bladed composite full feathering reversing propeller on a General Aviation Airplane designed, flight tested and now starting the endurance certification testing on a turbine test bench.
Noise files can be requested from MT-Propeller.

MT-Propeller, when founded in 1981 by Gerd Mühlbauer, always had the aim to make propeller powered traveling more comfortable. Gerd Mühlbauer, an engineer and test pilot, always focused on the customer’s needs, like all his management and engineering staff is doing.

With this vision, MT-Propeller created many firsts in history for the General Aviation World:
In 1981 the worldwide first electric constant speed propeller was created and certified. It improved performance of motor gliders and light aircraft.

Looking for more options and different airplanes, MT-Propeller created more than 27 worldwide certified propeller models until now. These propeller models can be combined with more than 220 aerodynamic blade designs to make a custom fit for every application.

This has already led to more than 210 STCs worldwide to retrofit existing airplanes with MT-Propellers.

Now MT-Propeller is already supplying 90% of all new European aircraft and 30% of the new US aircraft using a piston or turbine engine with the 2,3,4,5 bladed propellers.

In year 2004 the first 5 bladed full feathering prop with reversing was certified on the Shorts Skyvan SC-7.

In the turbine powered world many Firsts can be claimed again from MT-Propeller:
First 5 bladed certified composite turbine powered propeller on:

  • TBM 700/850 Series, the fastest in production single engine airplane Pilatus PC12, more than 150 are flying already with MT-Propellers.
  • King Air 90/200/300 Series with the low noise, improved overall performance, MT 5 bladed propellers.
  • The new Blackhawk PT6A-67A King Air 350, pushing this aircraft with MT 5 bladed props to 340+ KTAS and making it the fastest conventional turbo prop available today
  • Cessna 425 Series
  • Piper Cheyenne PA31T and T1
  • Piper Cheyenne PA42-1000, flying 360 KTAS with the MT-Propellers
  • Cessna 208 Caravan and many more.

With more than 1500 propellerturbine powered aircraft converted to the MT-Propeller system, MT made the 5 bladed prop an industry standard, leading the innovation and made competitors to follow.
Lower noise, lower vibration for a more comfortable ride with lower fatigue for pilots and passengers combined with a better take off, faster climb and cruise was the result after 35 years research in propeller design.

ANOTHER BIG FIRST, which we believe will change the General Aviation Propeller Powered Aircraft in the near future, happened in October 2016.

MT-Propeller egineers and test pilots flight tested the WORLDs first 7 bladed propeller used on a General Aviation Airplane.

The test flights, 8 flights in total with 5 hrs flight time contained a functional test, performance test and noise test with very promising results. In an uneventful test flight, the entire system performed on the PT6A-135A turbine installed in a Piper Cheyenne like used already for many years.

MT-Propeller is in technical talks with turbine engine manufacturers, to work together for the certification and customizing the gear box to get the best out of the UNDUCTED PROP FAN, how MT likes to call the 7 bladed prop.

More information on the MT-Propeller systems and also a sound file of the fly by with the WORLDS FIRST 7 bladed prop can be requested from techsupport@mt-propeller.com

With more than 18000 propellers systems and 65000 blades in service, which have accumultated 130 millon flying hours, MT-Propeller will continue pushing the propeller powered airplanes.

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.
