Abstract

A cradle for supporting a space vehicle such as an upper stage in a reusable launch vehicle (such as a space shuttle orbiter) cargo bay. The cradle includes means for supporting the space vehicle and any satellite attached thereto against launch loads and against abort landing loads. The cradle consists of two radial sections of a tube which, when closed, surrounds the space vehicle. One section is secured within the cargo bay. The second section is latched to the first edge of the second section and is hinged along the second edge. When the cargo bay doors are opened, the space vehicle is deployed by unlatching said latch and activating a first actuation means to rotate the second section about the hinge to move the second section outwardly of the cargo bay. A deployment probe connects the space vehicle to the second section. When the first section is fully rotated, a second actuation means rotates the deployment probe to move the space vehicle from the position in contact with the inner surface of the second section to an extended position extending away from the orbitor. The probe is then operated to release the space vehicle into space.

Dependent claims

A support structure for carrying a spacecraft in a cargo bay of a reusable launch vehicle during launch and for deploying the space vehicle in outer space comprising:

a bi-sectional cradle having generally annular configuration, with an outer surface conforming generally to the inner surface of a reusable launch vehicle cargo bay and an inner surface generally conforming to the outer surface of a space vehicle to be released in space;
said cradle being longitudinally divided into a first fixed section secured to said launch vehicle and a second movable section adjacent to an openable side of said cargo bay;
one abutting edge of said first and second sections including a releasable latch means;
the second abutting edge of said first and second sections including a first hinge means having a hinged line lying substantially parallel to the cradle centerline;
first actuator means for rotating said second section about said first hinge from a closed cradle position to an open deployed position upon release of said latch;
deployment probe means for securing a space vehicle to said second section for rotation with said second section;
said deployment probe means including second hinge means having a hinge line lying substantially parallel to said centerline;
and
second actuation means for rotating said probe and any space vehicle secured thereto from a first position with said space vehicle in contact with the inner surface of said second section to an extended position extending away from said section.
