Abstract
Nozzle-extending apparatus for a rocket engine of a space vehicle formed by placing a telescoping, extendible sleeve section of nozzle around a short fixed section of nozzle in a rocket engine. The extendible nozzle section (ENS) is extended by inflating a main inflatable pressure vessel (MIV), which is located within the fixed section of nozzle. The expansion of the pressure vessel drives the extendible section rearward to the end of the fixed nozzle section (FNS) where it is locked into place. A secondary inflatable pressure vessel (SIV) is then inflated to activate devices which decouple the MIV from the nozzles and allow the MIV to pressurize the engine cavity, thus jettisoning the MIV from the extended nozzle volume. This is accomplished by opening valves in the front surface of the MIV inflatable bag at several locations allowing pressurized gas to be released in the front space of the FNS (engine cavity), the pressurized gas then exerting rearward ejecting force against the bag and other components positioned inside the extended nozzle.
