Presented engine is a compilation of well-known KJ-66 and GTM-7o with some corrections. The engine reaches about 120000r/min, which are measured through a hole made in the cup and the measuring element is a phototransistor. The measurement of engine thrust is realized by the hook weight. Predicted thrust is about 13-15kg.
Due to the high speed and temperature, ceramic bearings were applied. The entire engine is fuelled with propane/butane gas, the outlet temperature is about 680 degrees Celsius.
