Clean Tech Aviation Introduction video 

CTA is a company that is positioning itself with an R&D unit in prototyping, testing and certifying aviation engines on various Bio Fuel blends. The initial testing and prototyping takes place on piston and turbo propeller engines followed by gas turbine (electricity plants) engines and jet engines in the business jet market.

The focus is initially on General and Business Aviation. This market is heavily underestimated and overlooked in size, numbers, volume and commercial and environmental footprints. Only in Europe there are 175.000 and in the world some 500.000 registered General and Business Aviation aircrafts.

CTA aims in the second phase on bio diesel piston engines and in the third phase on small gas turbine engines of the business jet market.

CTA aims in the third phase on the business jet and small freighter airline market for the same tactical reasons as the General Aviation, and secondly because the public psychological acceptance can be steered via the freighter trajectory, launching customer principles understanding it’s better for the environment and the consumer’s wallet, and proven to be safe to fly with over a period of time.

CTA executes prototyping, blending and testing on static testing lab at the University of Eindhoven and EnTrance location and dynamic testing lab at the Airport Teuge and Braunschweig location with the Bio CNG and Bio LNG on the aviationpiston and jet engines in use with  the General aviation aircrafts and through use of the FTO’s AOC’s.

We use a  rapid prototyping proces using  the Antanov 2 and its 9 cylinder radial engine as a Rapid Prototyping test platform because it is originally designed for usage of unstable fuels and therefore ideal to work with, until the Bio Fuel is proven stable for mass production and usage.

CTA purchased in september 2015 the Piper 44 twin engine seminole as the first testbed for the future bio fuel dynamic engine testing.


With the scientific test location CTA contracted the University of Eindhoven with a Promovendi trajectory used to define the bio fuel composition and usage as well as engine management components and systems.

The CTA static Bio Engine Testlab at EnTranCe Groningen will be used for the duration tests on each to be certified aviation engine following the Technical Readiness Levels.

The NLR supports CTA with following the TRL´s in its certification processes with the engine and aircraft manufacturors and Aviation Authorities.

CTA executes the dynamic bio engine duration flight tests from her locations at Airport Teuge and soon followed through her daughter company CTA GMBH at development at the airport Braunschweig in Germany.
