Abstract:
A machine for generating actuation force with rapid, precise, and large displacement motion comprising:a power source; a pneumatic power supply system operably connected to said power source for providing compressed air; an electric power source connected to said power source such that said electrical power source is recharged as needed by said power supply; an actuation system which comprises two burners, a push burner and a pull burner, each burner connected to said power supply and to said electrical power supply, said burners each having an exhaust port; two control valves, one for each burner, each connected to said pneumatic power source to receive compressed air, each connected to said control operator such that said control operator can only activate one of said two control valves at a time, and one of said control valves feeding compressed air to said push burner and the remaining of said control valves feeding air to said pull burner; a reversing turbine operably mounted next to the exhaust port of each burner such that said reversing turbins spins one direction, clockwise due to one burner's exhaust port and spins the opposite direction, counterclockwise due to the second burner's exhaust port; a speed reducing transmission operably connected to said reversing turbine to provide a predetermined rate of motion change to variations in speed of said reversing turbine; a ball-screw push rod mounted to said speed reducing transmission for providing preselected force and motion output; and a control operator connected to said actuator system to direct changes to the motion of said push rod in a predictable manner.
