Modular Piston Engine for Aviation


Total Cost of Ownership of turbines (compared to performance) is too high

Aircraft turbines have a high purchase price, high MRO* costs and high fuel consumption!

For example, for a turbine with 450 hp, the total cost at 5,000 flight hours is approx. 1.7 million €.
In general, the power loss in the higher altitude of these turbines is higher than in piston engines.

*MRO = Maintenance, Repair, Overhaul


We introduce a new generation of a modular aircraft piston engine 

The Engineers of KTW SYSTEMS challenge the “existing”.

We develop more fuel-efficient and low-emission engines for aviation, which meet the highest standards of operational safety.

Our successful team of engineers have built engines for racing sport, formula 1 and aviation and developed now the first:

modular aviation piston engine 8/12/16 cylinder

In the period of time from 1903 to 1945 piston engines were successfully implemented in aviation.
Since 1950, when most aircraft engines were replaced by gas turbines, piston engine technology has undergone an intensive evolution, for example engines which fly with Avgas*. This evolution initiated KTW SYSTEMS to improve the overall efficiency and quality of ‘piston’ powered aircraft engines.

Our internal project name is “Generation II”, because our founder Norbert designed the Generation I engine (not modular, V12), as he worked as Technical Director in the aerospace industry.

Based on our experience in developing high-performance engines and the integration of new technologies, the designed modular engines (diesel/kerosene principle) with water-cooling, set new standards in terms of cost and performance efficiency and fuel economy. The engine flies with kerosene (Jet-A1 EU, Jet-A US, RP-1,RP-2), which is available at every airport.

Due to the unique design of the engine, up to 3 engines (8/12/16 cylinders from 400 to 900 hp) can be developed during a development phase.
In addition to the high savings on development time and costs, the engine uses many identical components (valves, pumps, etc.). This reduction in complexity also has a huge impact on the cost structure.

No comparable engine under license to purchase.
For cost reasons engine trend is heading towards
aluminum/titanium light-weight aviation piston engines

25-40 % less fuel consumption compared to turbines with the same power

Fuel Specification: Kerosene (Jet-A1 EU, Jet-A US) or Diesel
– available at every airfield worldwide

Min. 50% lower purchase price than turbine,
TCO min. 30% lower than a turbine

Because of low consumption, more cargo can be taken
or with the same tank size can be flown longer.

Last but not least:  MORE PROPULSIVE POWER as turbine


without pressurized cabin up to 4,000 m

Small Aircrafts

Small transport and business aircraft

(altitude 7,600 m)


Max. Altitude for drones 16,000 m


Future Market

Key Figures compared to Turbines / Turboprops:

25 - 0 %
less fuel consumption
> 0 %
in TCO savings
> 0 %
lower acquisition costs
