Abstract
Abstract A dual structure aerospace vehicle 10 having an aeroshell structure 11 and an internally disposed separable and reusable integral tank/thrust structure 13 is disclosed. Tank/thrust structure 13 is insulated for cryogenic fuels and the cavity 24 within aeroshell 11 is insulated from the tank/thrust structure (FIG. 2). An internal support ring 26 within cavity 24 serves as attachment for lugs 30 on tank/thrust structure 13 via double hinges 50 (FIGS. 3 and 4). The aft end of tank/thrust structure 13 is provided with rocket engines and exit nozzles 33, 34, 35 with trunnion support 37 supporting the tank/thrust structure within aeroshell 11.

Claim 2
Dependent Claim
63 words
An aerospace vehicle comprising a reusable aeroshell structure and a releasably contained reusable separate integral fuel tank/thrust structure disposed within said aeroshell vehicle structure, connection means releasably attaching said aeroshell structure and said fuel tank/thrust structure, said connection means providing unrestrained thermal growth between said aeroshell structure and said integral tank/thrust structure while concurrently transmitting aero-inertial loads without relative motion between said structures.
Claim 3
Dependent Claim
84 words
The aerospace vehicle of claim 1 wherein said movable connection means comprises at least two integrally secured frame structures disposed about the periphery and spaced longitudinally within a cavity within said aeroshell vehicle structure; a plurality of hinges removably secured to one of said frame structures at spaced intervals thereabout; a plurality of spaced lugs integrally secured at said spaced intervals about the periphery of said fuel tank/thrust structure and attachments serving to connect said plurality of spaced lugs to said plurality of hinges.
Claim 4
Dependent Claim
41 words
The aerospace vehicle of claim 2 wherein each said plurality of hinges comprise a face plate fixed to said one frame structure and a pair of pivotal plates connected to said face plate via a pair of parallel hinge joint connections.
Claim 5
Dependent Claim
26 words
The aerospace vehicle of claim 3 wherein said attachments comprise ball joints integrally secured to one of said pivotal plates and pivotally secured to said lugs.
Claim 6
Dependent Claim
27 words
The aerospace vehicle of claim 4 wherein said ball joints are pivotally secured to said lugs via a pivot pin extending through said joint and said lugs.
Claim 7
Dependent Claim
58 words
The aerospace vehicle of claim 2 including a trunnion connection provided between said aeroshell structure and said integral tank/thrust structure, said trunnion connection comprising a trunnion secured adjacent the aft end of said tank/thrust structure and a bearing surface receiving said trunnion and supported by another of said frame structures adjacent the aft end of said aeroshell structure.
Claim 8
Dependent Claim
45 words
The aerospace vehicle of claim 1 including thermal insulation means disposed adjacent to said tank/thrust structure and additional thermal insulation means disposed adjacent to the cavity of said aeroshell vehicle structure to insulate said vehicle structure from said tank/thrust structure and from external environmental heating.
Claim 9
Dependent Claim
117 words
An aerospace vehicle comprising: (a) an aeroshell vehicle body having a pair of wings, a canopy, a payload compartment, and an elongated internal cavity extending substantially the length of said aeroshell vehicle body; (b) a propulsion system for said aeroshell vehicle body removably disposed within said internal cavity of said aeroshell vehicle, said propulsion system including at least one liquid fuel tank and at least one rocket engine in operative connection with said fuel tank, first thermal insulation means disposed adjacent to said at least one liquid fuel tank, and second thermal insulation means adjacent to said elongated internal cavity of said aeroshell vehicle body, and connection means releasably attaching said aeroshell structure and said fuel tank.
Claim 10
Dependent Claim
117 words
An aerospace vehicle comprising: (a) an aeroshell vehicle body having a pair of wings, a canopy, a payload compartment, and an elongated internal cavity extending substantially the length of said aeroshell vehicle body; (b) a propulsion system for said aeroshell vehicle body removably disposed within said internal cavity of said aeroshell vehicle, said propulsion system including at least one liquid fuel tank and at least one rocket engine in operative connection with said fuel tank, first thermal insulation means disposed adjacent to said at least one liquid fuel tank, and second thermal insulation means adjacent to said elongated internal cavity of said aeroshell vehicle body, and connection means releasably attaching said aeroshell structure and said fuel tank.
