Abstract:

A launch tube assembly, including an aft launch tube portion, a forward launch tube portion, and a transfer sleeve having a first end fixed to and adjacent to the forward end of said aft launch tube portion and a second end adjustably receiving the forward launch tube portion. A forward end of the aft launch tube portion faces a rearward end of the forward launch tube portion within the transfer sleeve. An adjustable plenum is present having a volume within the transfer sleeve defined by an adjusted distance between the facing ends of aft and forward launch tube portions. An end cap is pinned to a forward end of the forward launch tube portion, a gas generator housed in the aft launch tube portion, and a countermeasure device is housed in the forward launch tube portion. An adjustably selected volume of the plenum is such that a gas generated by the gas generator will enable propulsion of the countermeasure device at a predetermined acceleration from the forward launch tube portion. 1 figure
