Abstract

A method provides for shooting a missile-rocket. The missile-rocket has two movable parts and a propellant. The propellant is disposed between the one movable part and the first end of the other movable part. The missile-rocket undergoes three phases of acceleration. During the first phase, the method includes the steps of activating the propellant, moving one of the movable parts in response to the activation of the propellant, and urging the one of the movable parts to engage the other one of the movable parts. During the second phase, the method includes the step of urging the other one of the movable parts in response to the engagement. During the third phase, the method includes the step of releasing gases formed by activating the propellant from the missile-rocket to further urge the missile-rocket. The movable parts are preferably a shell and a core. In one embodiment, the core is moved in response to the activation of the propellant and urged to engage the front end of the shell. The shell is urged in response to the core engaging the front end of the shell. Further urging of the core and the shell is by releasing gases formed by activating the propellant from a chamber formed by the core and the shell. In another embodiment, the shell is moved in response to the activation of the propellant and urged to engage the core. The core is urged in response to this engagement. Further urging of the core and the shell is again by releasing gases formed by activating the propellant from a chamber formed by the core and the shell.

A method of shooting a missile-rocket having inner and outer parts one of which is movable relative to the other in a primary acceleration phase and both of which are movable together in a secondary acceleration phase and in a subsequent rocket phase, the inner and outer parts forming a chamber therebetween containing a propellant, wherein there is a launching device for the missile-rocket, comprising:

igniting the propellant in the primary acceleration phase thereby creating gas pressure in the chamber to move one of the parts in a predetermined direction relative to the other part and into engagement therewith, thereby to initiate the secondary acceleration phase wherein the gas pressure in the chamber causes the one part to move the other part in said predetermined direction;
maintaining said other part immobile relative to the launching device during the primary acceleration phase;
blocking escape of gas from the chamber during the primary and secondary acceleration phases whereby substantially all of the energy of the gas pressure in the chamber is used to accelerate first the one part and then both of the parts respectively in the primary and secondary acceleration phases;
and
enabling gas to escape from the chamber following the secondary acceleration phase thereby to initiate the rocket phase and provide reactive forces to sustain propulsion of the missile-rocket in said predetermined direction.
