Variable inertia launch ramp

Abstract

A launch ramp includes a hollow body having first and second ends and upper and lower walls which converge to a relatively sharp edge at the first end of the body. Support legs are mounted to the body adjacent to the second end thereof, the legs being extendable an appreciable distance from of the bottom wall so that when the edge and the legs rest on a horizontal surface, the top wall is inclined at an appreciable angle relative to that surface. The hollow body defines a fluid-tight chamber which may be filled with a fluid substance to change the weight, inertial characteristic and stiffness of the ramp body.
