Missile launching system on aircraft - has two stage double acting rams at ends to eject missile downwards

摘要

The missile launcher has fore and aft ejection rams, pref. two-stage double-acting rams. It has a choked flow gas system to prevent interaction between the rams and avoid back pressure in the breech chambers. Two gas cartridges in two breech chambers supply ejection gas pressure and a third cartridge in a third breech chamber supplies gas for subsequently retracting the rams. The ejection gas pressure also actuates mechanisms for releasing fore and aft missile suspension hooks and crutching assemblies, and for withdrawing an umbilical electrical service plug. Each ram comprises an outer casing, an inner fixed hollow shroud tube and two relatively-moving members with annular pistons that extend telescopically from within the space between the casing and the shroud tube.
