Abstract: A reusable flyback satellite system comprises a refly apparatus and accelerating and positioning apparatus. The refly apparatus provides acceleration and injection into orbit, on-orbit functions services for supporting a payload, de-orbiting, re-entering and landing on a runway. The accelerating and positioning apparatus is attached to a carrier aircraft, the accelerating and positioning apparatus releaseably supporting the refly apparatus. The carrier aircraft positions the accelerating and positioning apparatus at a desired first position wherein the accelerating and positioning apparatus is detached from the carrier aircraft. Thereafter, the accelerating and positioning apparatus positions the refly apparatus to a second position wherein the refly apparatus is detachable from the accelerating and positioning apparatus. The second position is such that the refly apparatus can achieve a desired orbit.

Abstract: A shock and vibration mount includes a resilient elastomeric member arranged to act with two spaced spring units, each of which includes a group of stacked, disc-shaped annular springs. Low level impacts and vibrations are transmitted from a rod, that is movable with the impacted member or with a member reacting to an impact, to the elastomeric member through either of the stacked units, high intensity shocks being attenuated first by the elastomeric member and then by one of the stacked units.

Abstract: An object restraint system is provided with a collar for gripping the object and a plurality of struts attached to the collar and to anchor means by universal-type joints, the struts being arranged in tangential relation about the collar.
