Abstract
Abstract A yieldable mounting ring of teardrop cross section is mounted between a solid wall rocket engine thrust chamber wall and a sleeve holding the gimbal assembly which provides for the thrust direction control capability of the engine. The ring is segmented to expand and contract and allow unrestricted dimensional changes in the thrust chamber while maintaining the chamber in alignment with any attached structural elements.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
Means for attaching structural elements to a solid wall rocket engine thrust chamber, said attachment means comprising a yieldable ring partially disposed in a shallow groove machined in the surface of the outer wall of the thrust chamber, a gimbal mounting sleeve surrounding the outer wall of the thrust chamber and spaced therefrom, said ring being positioned between the chamber and said sleeve, said sleeve having a shoulder thereon for operative engagement with a part of said ring, an injector bolted against the upstream face of the thrust chamber, the bolts holding said injector threadably engaging said sleeve and serving to transfer the compression load thereby produced through said ring to the chamber, said attachment means allowing substantially unrestricted thermal growth of the chamber while maintaining the chamber in alignment with the attached structural elements.
Claim 2
Dependent Claim
135 words
Means for attaching structural elements to a solid wall rocket engine thrust chamber, said attachment means comprising a yieldable ring partially disposed in a shallow groove machined in the surface of the outer wall of the thrust chamber, a gimbal mounting sleeve surrounding the outer wall of the thrust chamber and spaced therefrom, said ring being positioned between the chamber and said sleeve, said sleeve having a shoulder thereon for operative engagement with a part of said ring, an injector bolted against the upstream face of the thrust chamber, the bolts holding said injector threadably engaging said sleeve and serving to transfer the compression load thereby produced through said ring to the chamber, said attachment means allowing substantially unrestricted thermal growth of the chamber while maintaining the chamber in alignment with the attached structural elements.
Claim 3
Dependent Claim
33 words
The attachment means defined in claim 1 wherein said yieldable ring is segmented to allow movement thereof in the groove in the wall of the thrust chamber in response to dimensional changes thereof.
Claim 4
Dependent Claim
57 words
The attachment means defined in claim 2 wherein the cross-sectional shape of said yieldable, segmented ring is of teardrop configuration, the larger end of said ring being disposed in the shallow groove in the outer wall of the thrust chamber and the smaller end of said ring being positioned against the shoulder on said gimbal mounting sleeve.
Claim 5
Dependent Claim
16 words
The attachment means defined in claim 3 wherein said yieldable, segmented ring is fabricated of titanium.
