After a construction period of about two years, MT-Propeller has now opened three new buildings with a total of about 8,000 sqm (86,000 sqft), in order to further increase its production and service capacities due to the continuous growth in orders and new developments.
All metal parts for MT-Propellers can now be manufactured at the headquarters, providing short transport distances and greater flexibility. A new aircraft hangar provides additional space for direct installation of propellers on customer aircraft, and the new buildings also increase sales, spare parts and shipping capacity, as well as areas for the training of the MT-Propeller staff and the worldwide service stations.
In total, MT-Propeller now operates six buildings with a total of 15000 sqm (161000 sqft) at Straubing Airport, plus the composite blade production facility (4 km) 6 miles from the airport with a further 5000 sqm (54000 sqft).
When Gerd Muehlbauer started MT-Propeller in 1981 with 5 employees, the company was located in one small airport building which is still part of the company today. Over the last 43 years, the company has grown into a world leader in high performance aircraft propellers with 280 employees at the headquarters in Germany and additional places in the Czech Republic and the USA.
The key to MT-Propeller's success, is that the company is owned and operated by Aviators for Aviators and this comes with a continuous investment in innovative new developments by its engineers - most of whom are pilots themselves - the company’s own test pilots, many long-experienced employees who use and pass on their experience and knowledge in the development and construction of the ‚Propellers Made in Germany’, continuous training of all employees and highest quality standards.
MT-Propeller serves the General Aviation market with over 230 propeller STCs for aircraft models ranging from motor gliders to regional airliners. The product range extends from 2 to 7 blade propellers for aircraft up to 5,000 hp, as well as airships, hovercraft and wind tunnels.
Over 33,000 MT propeller systems with over 115,000 natural composite blades are in service, having accumulated over 180 million flight hours.

MT-Propeller received the ANAC Brazil STC 2023S08-11 for the installation of the 5-blade MTV-27 MT-Propeller on the Piper PA-46-350P (Malibu Mirage) powered by P&WC propeller turbines.
The 5-blade MTV-27-1-E-C-F-R(P)/CFR203-58d propeller provides a general performance improvement (10% shorter take-off distance, 10% better climb performance, 3 kts faster in cruise), approximately 3 lbs less weight than the original metal propeller and a cooler ITT on ground with the condition lever at low and high idle position.
The installation is already certified by EASA #10081080.
The installation provides a TBO of 4500 hours or 6 years, whatever comes first, for low maintenance costs. There are no intermediate inspections needed between the TBO which requires the propeller removal and there are no rpm restriction for the complete operational range.
The world's first 7-blade propeller is now installed on 75 Pilatus PC-12 aircraft in Europe and the USA.
he 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 take-off performance improvement by 20%, improved climb and cruise
- a very low jet-like noise level both in the cabin and outdoors
- 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.
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.
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.
MT-Propeller received the amendment of the FAA STC for the installation of the MTV-27-1( )-C-F-R(P)-J/CFR300-82( ) Propeller on the Airtractor AT-802() with an engine power of up to 1700 SHP. This STC is already certified by EASA 10072601 R1.

The installation of the 4-blade MTV-14 Propeller on the Cessna ()210() significantly reduces the noise, so that the aircraft can be operated also in Switzerland in the lowest noise category.
On a Piper PA31T1 equipped with P&W PT6A-135A propeller turbines, the World’s first 11-bladed aircraft propeller took the sky with an impressive noise and sound signature.
The very promising results in static thrust, 15% increase over the standard certified 5-bladed propeller, and the jet-noise signature showed another time what could be possible in the propeller developments.

The Silent 7 defines a new level of comfort, performance, so far never experienced on any turboprop aircraft before.
When starting developing the world's first 7-bladed propeller for general aviation in 2016 MT-Propeller had the same vision like in year 1999 when we came up with the first 5-bladed prop for turbo props. The 5-bladed prop became an industrial standard with more than 2500 propeller sold for various kinds of turbo props and it is still an ongoing success story. The 7-bladed propeller is pushing the new limits for certain applications to go beyond the achievement of the 5-bladed propellers.
