Abstract
An improved high energy impulse rocket includes a motor case containing propellant composed of individual, free flowing granules of a predetermined shape and unbonded to said motor case. The propellant has a high burning rate of 100 milliseconds or less and generates chamber pressures of up to about 50,000 psi. The rocket motor includes a reentry nozzle open at one end and connected to an exit nozzle, the reentry nozzle forming an annulus to contain the propellant and also forming a barrier to prevent ejection of the propellant during burning. Acceleration of the rocket assists in maintaining the propellant within the motor case, which acceleration may be as high as 20,000 g generating a velocity as high as 10,000 fps. Such a rocket offers unique advantages, especially as a device to punch an opening in a wall structure, the details of which are described as well as other details of the improved and relatively inexpensive impulse rocket.
