ABSTRACT:
A fuel injector 14 passes through wall 10 to inject fuel into a hot supersonic air flow 12. Wedge seals 26, 28 seal against leakage in cooperation with injection air flow 37, being compressed within seal carrier 16. Face seals 30, 32 are compressed by cover plate 34. Inboard seals 26, 44 are preferably more porous than the outboard seals so that there is a leakage of cooling air through crevice 44.
