Abstract
Rotary engines have been proposed as an alternative to reciprocating internal combustion engines. Among many rotary geometries, rotary-piston engines present sealing advantages. However, some points of their sealing grid are simply neglected even in the absence of experimental data validating their efficiency. Hence, it’s important to better understand the leakage mechanisms in order to avoid sealing problems in rotary-piston projects. This paper presents an experimental methodology to test new rotor sealings configuration for a rotary-piston engine. Two different leakage paths were assessed: radial and circumferential leakages. Non-contact sealing and a mechanical sealing configuration were designed and tested. The results have shown better sealing efficiency using mechanical configuration and higher leakage on the circumferential direction.
