Specifications

The Stuttgart Engineering Turboprop STV 100 and STV 130 Engines

provide a complete new approach to the motorisation of ultralight, light aircraft and helicopters.

This is not about a conversion of some jet starter, but a real new turboprop engine build from scratch to meet the requirements and satisfy the demands of light and ultralight aircraft of the new generation. The result is a light two shaft, strong, fuel efficient, affortable turboprop engine. Great features, such as the dual independent fuel system provide an unmatched reliability.

 

 

What we have done so far

Until October 2016 the turboprop has more than 800 hours on simulated flight circle tests with power settings for takeoff, climb, cruise and descent. These tests showed a vibration free, robust, agile and flexible engine that can constanly provide the full power from zero and up to 33.000 ft. The fuel consumption lies at about 27 kg/hr of Diesel for the 100 hp engine.

 

Extended flight tests are to start in 2017.
