Abstract

The 55 hp rotary engine did not achieve the rpm beyond 7500 because of leakage as a result of damage on the apex seals. Investigation showed that a foreign hard object got embedded in the coating on the inner surface of the trochoid. This had acted as a cutting tool and made grooves on all the three apex seals. The foreign abject was found to be made of a tool steel. It appears most probable that the source of the foreign object is a tool used during machining of the trochoid. The hard particle was present either in the drilled holes or elsewhere in the trochoid which came out and entered into the combustion chamber during engine runs. A detailed analysis of the failure is presented in this report.
