ROTARY COMBUSTION ENGINE TROCHOID COATINGS AND SEALS

This paper presents a review of Curtiss-Wright's efforts to identify or develop sucessful apex seal/trochoid sealing systems for the rotary engine. Included are descriptions of the various wear test rigs utilized to evaluate apex seal/trochoid coating combinations. Laboratory seal-coating screening procedures are detailed along with engine test results. Seal-coating design considerations including factors affecting seal loading and wear are described. Data are presented on a newly developed plasma spray coating containing titanium carbide.
