ABSTRACT:
A missile launcher having fore and aft two-stage double-acting ejection rams is provided with 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, the ejection gas being admitted down the interior of the shroud tube. The aft ram has a yoke to engage the missile and the forward ram a side plate. The forward crutching assembly comprises a spring-loaded coned nut and the aft crutching assembly a spring-loaded wedge.
