ABSTRACT:
An improved cased telescoped ammunition round includes a propellant charge disposed in a tubular case and having an axial bore. The case is composed of a skin tube and forward and aft end caps on opposite ends of the tube. The case defines a chamber that contains the propellant charge. Separate forward and aft tubes are disposed in the case extending at least partially through the axial bore of the propellant charge from respective forward and aft ends of the bore. The separate tubes are attached respectively to the forward and aft end caps of the case. A projectile is housed within the separate tubes and the axial bore of the propellant charge, and a primer is disposed within an aft end of the aft tube. The primer is actuatable for igniting the propellant charge to cause firing of the projectile forwardly from the case. Internal spider-like flexure springs having slightly different configurations are associated with the forward and aft ends of the separate tubes adjacent the forward and aft end caps and with the opposite ends of the case skin tube. The flexure springs are capable of resiliently and yieldably flexing to provide positive end cap retention during round firing and end cap retraction after firing to ensure dimensional recovery of the case after firing of the projectile so that the case can be ejected from a gun chamber.
