Abstract

A tri-rotor ballistic engine comprising a frame, a drum rotatably mounted on the frame having an output shaft, with a power cavity and an energy absorbing cavity defined therein. A power shaft is rotatably mounted in the drum. A reaction shaft is also rotatably mounted in the drum and axially aligned with the power shaft. A differential gearing or linkage device interconnects the power shaft, reaction shaft and drum. A pair of inner power pistons are connected to the power shaft and extend radially outwardly thereof and into the power cavity of the drum. The drum includes a pair of outer power pistons which are integral with the drum and extend radially inwardly into the power cavity to define four power chambers with the inner power pistons. Two or more energy storing paddles extend radially outwardly from at least one of the power and reaction shafts and into the energy storing cavity of the drum. The drum, in this area, is provided with two or more energy storing separators which extend into the energy storing cavity and define a plurality of energy storing chambers with the energy storing paddles.

Dependent claims

A tri-rotor ballistic engine comprising:

a frame;
a drum, rotatably mounted on said frame, having an output shaft, a power cavity defined therein;
a power shaft rotatably mounted in said drum;
a reaction shaft rotatably mounted in said drum;
a differential interconnection means interconnecting said power shaft, reaction shaft and drum so that when said drum is rotated at a constant angular velocity and one of said power and reaction shafts is held at zero angular velocity, the other of said power and reaction shafts rotates at twice said constant angular velocity;
at least one inner power piston connected to said power shaft extending radially outwardly thereof and into said power cavity of said drum;
said drum including at least one outer power piston extending into said power cavity to define at least two power chambers with said at least one inner power piston;
first hydraulically operated holding means connected to said power shaft for holding said power shaft at zero angular velocity;
second hydraulically operated holding means connected to said reaction shaft for holding said reaction shaft at zero angular velocity;
control means connected to said first and second holding means for selective activation thereof;
and
power fluid means connected to said at least two power chambers for selectively pressurizing said power chambers and rotating said drum.
