Impulsive propelling system

An impulsive propelling system comprising:

• a stationary base frame;
• a movable frame body disposed adjacent to one side of said stationary base frame and movable in an advancing direction away from said stationary base frame;
• an energy storing member having a first end secured to said stationary base frame and a second end secured to said movable frame body, said energy storing member resisting movement of said movable frame body in the advancing direction, and
• a pushing device having one end secured to said stationary base frame, and an opposite end abutting against said movable frame body to apply force to said movable frame body in the advancing direction, said force being resisted by tensile stress in said energy storing member which holds said movable frame body in place, until the tensile stress in said energy storing member reaches a value to produce fracture thereof, said energy storing member being disposed between said stationary base frame and said movable frame body, and said movable frame body is freely movable independent of said pushing device and said stationary base frame without being restrained by said pushing device and said stationary base frame so that the movable frame body moves impulsively and upon the fracture of said energy storing member, wherein said movable frame body is adapted to support a test dummy which is propelled, upon fracture of said energy storing member, at a high instantaneous speed in said advancing direction of up to 108 km/hr. to simulate conditions of a car crash.
