Abstract: A high-precision magnetic suspension accelerometer for measuring the linear acceleration of a spacecraft is provided, comprising a magnetically shielded vacuum chamber system, a magnetic displacement sensing system, a magnetic suspension control system and a small magnetic proof mass. A optical coherence displacement detection technique is utilized for precisely measuring the position and the posture of the small magnetic proof mass in real time, and a magnetic suspension control technique is utilized for precisely controlling the position and the posture of the small magnetic proof mass to be brought back to the origin, so as to keep the small magnetic proof mass in the center of the systemic inner chamber. When the spacecraft is subject to a non-conservative force, the magnitude and direction of the acceleration can be precisely measured via the measurement of currents in the position control coils due to the acceleration of the spacecraft proportional to the currents of the position control coils.

Abstract: A chemical-electromagnetic hybrid propeller with variable specific impulse. Fuel gas ejected out from a spraying tube of the chemical propeller through chemical propulsion enters an ionization chamber through a first magnetic mirror tube for ionization. The fuel gas after ionization is heated up by radio-frequency ion cyclotron waves in an ion cyclotron wave heating chamber so as to improve the kinetic energy. Then a second magnetic mirror tube is used, so that ions in the fuel gas after the ionization are heated up many times in a reciprocating manner between the magnetic mirror tubes, and ejected to generate forward propulsion force. By means of the propeller, the propulsion force and the specific impulse are greatly increased.

Abstract: An air connector is described mountable opposite an intake or exhaust port in an associated intake or exhaust pipe of an internal combustion engine to allow the port to communicate selectively with the associated pipe and with a compressed air storage tank. The connector comprises a stopper mounted on a rod movable by an actuator between an open position in which the port communicates with the associated pipe and a closed position in which the stopper seals around the entrance of the port to isolate the port from the associated pipe. An air passage is provided in the stopper and the rod to allow communication between the port and the compressed air storage tank when the stopper is in the closed position, and a check valve is arranged in the air passage and biased in a direction to prevent escape of air from the compressed air storage tank in all positions of the stopper.
