ABSTRACT:
A multi-stage vehicle separation system and method that facilitates an active separation on the booster by igniting a small quantity of propellant in the dead volume between the second stage rocket motor nozzle and the booster dome. In the most general embodiment, the invention includes a nozzle; a first fuel propellant disposed within the nozzle; a thermal barrier separating the first and second fuel propellant, an environmental seal protecting the second fuel propellant and an arrangement for activating the first fuel propellant. The nozzle is disposed in an upper stage of a two-stage vehicle. An arrangement such as a V-Band clamp is included for retaining the lower stage of the two-stage vehicle. Electronic commands release the lower stage and activate the first propellant in a timely manner to effectively separate the lower stage from the upper stage. The embedded propellant is activated with an arm fire device.
