Twin Mustang-F82 with  4 blade Propeller MTV-4-1 The new 4-bladed Warbird MTV-4-1 MT-Propeller is now certified by FAA TC P00066IB for the use on the Twin Mustang F82 and was initially installed there, but it can be also installed on the P51.

By designing this brand-new propeller model, MT-Propeller has solved the problem that it is becoming increasingly difficult sourcing old airworthy propeller parts to keep those aircrafts flying with the original propellers. The F82 has already accumulated many flying hours with the MTV-4, by flying across the US airshows.

This propeller is already type certified by EASA TC EASA.P.501

The power rating of the MTV-4-1 is certified up to 2200 shp, this will cover most of the applications requiring such a propeller system.
TThe propeller looks like the original classic propeller, but the blades are made of the MT natural composite material with an aluminum hub and a steel spline adapter for the #50 spline.
These blades are certified and tested for unlimited life.

Several propellers for Warbirds have already been manufactured.

This proves again the MT-Propeller philosophy - engineered by aviators for pilots - to make the best products available for the aviation community.

Brand new project - Piper Meridian converted to a PT6A-135A , to make it a XR135A Conversion


July, 2023
M500 Meridian converted Having ideas how to make aircraft quieter and more efficient, MT-Propeller took the Piper M500 Meridian as a new program, replacing the original PT6A-42A engine with a PT6A-135A engine. Initial flight test data show basically the same performance, reduced noise with a maximum propeller RPM of 1900 and an increased range of:
RANGE:
(Max. range with max fuel (ISA, MTOW, no wind, one pilot, 45 min fuel reserve)

  • 203 KTAS cruise speed: 1340NM (2479km) @ 30000ft
  • 203 KTAS cruise speed: 1290NM (2387km) @ 28000ft
  • 240 KTAS cruise speed: 1160NM (2146km) @ 28000ft
  • 258 KTAS cruise speed: 960NM (1776km) @ 25000ft

The flight tests were performed with a 5-bladed Quiet Fan Jet MTV-27 Propeller, the propeller is already certified on the original Piper Meridian and can be used also – if already installed – on this conversion.

Maintenance cost will be reduced by installing the new engine.
Changing the engine family from the mid-size category to the small-size, makes an impressive difference for the operating cost.
Direct cost per mileage will be similar to the PA46- 350P Lycoming-powered Mirage, but with a top speed of up to 260 KTAS @ 30,000 ft. EASA certification is planned for second quarter of 2024 with the FAA STC following.

75 FLYING PC-12 enjoy MT's Silent 7 propeller

July, 2023
PC-12 with MTV-47 The silent 7 Propeller The world's first 7-blade propeller is now installed on 75 Pilatus PC-12 aircraft in Europe and the USA.

The installation of The Silent 7 MT-Propeller on the Pilatus PC-12 sets new limits for certain applications, exceeding the performance of 5-blade propellers.

The advantages of The Silent 7:


  • certified takeoff performance improvement by 20%, improved climb and cruise
  • a very low noise level both in the cabin and outdoors , like jet-like noise
  • a very smooth operation

The Pilatus PC-12 STC with The Silent 7 MT-Propeller meets the highest noise regulations in European countries for unrestricted airport operations.
In April 2023, the STC for the Pilatus PC-12 combined with the 7-blade MTV-47 propeller was again updated to reflect the improvement in certified performance in the AFMS, reducing the required take-off length by approximately 20% compared to the original certified data. Already converted PC-12 aircraft can receive the latest certified performance range of MT propellers.

The 100 000th MT-Propeller blade was manufactured May 2023


July, 2023
PC-12 with MTV-47 The silent 7 Propeller MT-Propeller natural composite blades have been a success since they were first built.

Because of their natural composite construction, they are much lighter than aluminum propeller systems, have a higher vibration dampening coefficient compared to foam core composite blades.
By this they also reduce vibration because the composite material does not support harmonics. No restricted rpm ranges, red bands for those blades on certified installations. Those blades have an unlimited blade life, because they can be brought back to the exact factory dimensions during overhaul. Even after a ground strike the blade tips can be rebuilt to the new original dimensions.

The first MT-Propeller blades manufactured in year 1981 are still in service.
Their light weight makes it possible to add more blades to a propeller system, which means that 3-blade conversions, for example, can run more quietly than large 2-blade systems, and in addition, smaller propeller arc disks have less drag than larger diameter propeller arc disks. Even 7-bladed propellers for turboprops are now available with lower loads on the engine during operation, compared to classic propeller systems.

This makes MT propellers the first choice for many aircraft owners and aerobatic pilots.

MT propeller blades are also the best choice for wind tunnels, airships and hovercraft.

EASA STC for Kodiak 100 series on floats with 5-blade MT-Propeller MTV-27

Atting, February 2021

Kodiak 100 on floats with MT-Propeller MTV-27 MT-Propeller Entwicklung GmbH has received the EASA STC Nr. 10069627 REV. 1 for the 5-blade Quiet Fan Jet composite propeller MTV-27-1-E-C-F-R(P)/CFR240-55( ) on the Quest Aircraft Design LLC Kodiak 100 series with Aerocet 6650 floats powered by a Pratt & Whitney PT6A-34 propeller turbine.

The FAA STC is in progress.

MT-Propeller Vice President Martin Albrecht says, that the installation feature the following advantages:




  • Take-Off improvement by 20%
  • No propeller speed restrictions on ground while operating in low idle
  • Lower ITTs during start-up for less engine wear
  • Significant cabin noise [up to 5 dB(A)]and vibration reduction

MT-Propeller President Gerd Muehlbauer announces, that the installation features the following advantages compared to the original 4-blade propellers:



  • The 5-blade MT-Propeller has a smaller diameter of about 8 inch compared to the original 4-blade propeller, this means more ground clearance of about 4 inch for less FOD and also more clearance to the fuselage, therefore less cabin noise from the prop tips
  • Take-Off of the Beech 1900 is improved by 4%, so compared to the original AFM a higher safety for the calculated take-off run
  • The MTV-27 has no propeller ADs
  • The 5-blade MT-Propeller reduces the propeller noise by up to 5 dB(A)
  • The MTV-27 has bonded on wide chord nickel alloy leading edges for superior erosion protection of the blades
  • TBO for the MT-Propeller is 4500 hours or 6 years, whatever comes first, for low maintenance costs
  • No intermediate inspections are needed between the TBO which requires the propeller removal
  • Reduced costs for spare parts, like blades and lower overhaul costs, for the complete propeller assembly
  • No rpm restriction for the complete operational range
