ENGINE FOR PARAGLIDING

The unceasing research, the constant development, together with the experience acquired during the races, set up THOR, the new 2 stroke paramotor engine proper for the paragliding usage. The project was born from the studies and the planning skills of the R&D’s technicians who were able to find out the possibility to manufacture a compact and light 2 stroke engine. Afterwards the developments and the perfect set up were possible thanks to the testing technologies and to the test benches available at Polini together with the know-how acquired during many years of experience in the races world.

HIGH PERFORMANCE AND PURE TECHNOLOGY

Polini Thor engine features advanced technical solutions. It was projected to achieve the best weight-power ratio but, at the same time, to optimize the thermal and moving parts functions. The cooling system was studied with great care and Polini opted for the forced air. The transmission group includes the clutch in oil bath with maximum stability.

ROLLER TEST BENCH

THOR is an engine that has been tested for a long time on this specific test bench in order to find the longest torque arc to make it able to fly at every rpm rate and with the best and constant performance.

FINAL TEST BENCH

At the end of assembly line, the engine is always tested on the test bench at the fly conditions with the propeller fitted: we calibrate the carburation and after a running-in cycle we measure the maximum thrust value provided by the propeller. The thrust value must respect a short tolerance range to pass the final inspection and it must be able to grant a high performance constancy between all the engines produced.

PROPELLER THRUST TEST BENCH

This test bench was developed expressly for this engine. Through a charge cell with digital visualizer together with a digital revolution indicator we can measure the thrust at every rpm. In this way we are able to test the propellers to achieve the best thrust and the most performing propeller.

TEST FLIGHT

The engine was tested while flying in a variety of weather conditions and the results achieved turned out to be very good. It demonstrated great reliability with low fuel consumption and suited for race use too.
