Technical Field

The invention relates to the technical field of superconductivity and aerospace launching, in particular to a supersonic launching system based on electric and pinning hybrid magnetic suspension.

Background

The emitting system requires low vibration in the motion process due to the particularity of carrying the tested object, and the tested object is prevented from being damaged due to overlarge vibration amplitude. The existing near-ground launching mainly realizes supporting and guiding in a mode of constraint matching of a sliding shoe and a sliding rail, and achieves the aim of vibration reduction by isolating vibration response caused by collision between the sliding shoe and the sliding rail through vibration reduction design of the sliding shoe. When the high-speed transmission is carried out, the collision amplitude is increased sharply, and great challenges are brought to the vibration reduction design of the sliding shoes. Therefore, supersonic launch systems are mostly supported in a magnetic levitation manner, as Holloman launch base in the united states is developing a magnetic levitation bearing, a launch system around Ma 10.

However, the existing magnetic suspension supporting mode cannot realize the full-speed suspension operation of the launching system from low speed to supersonic speed.

The induction and synchronous hybrid linear motor is adopted as a power source, and the following advantages are achieved: 1. improving the thrust of the system: the power of the launching system is provided by the synchronous motor and the induction motor together, the total thrust of the power system can be improved according to the optimized design, and meanwhile, the proportion of the thrust generated by the synchronous and induction motors is reasonably distributed, so that the design difficulty of the motor is reduced; 2. the system reliability is improved: the superconducting magnet is formed by low-temperature or high-temperature superconductors, external electromagnetic or mechanical disturbance exists in the running process of the synchronous motor, the temperature rise of the magnet can be caused, and the superconducting magnet can be quenched and lose the propelling function under the severe working condition. The induction motor can continuously provide power for the launching system after the superconducting magnet is quenched, so that the failure risk of the power system is reduced; 3. reducing the cost of the power system: by adopting a single linear induction motor, the rigidity and the strength of the induction plate are insufficient under the condition of high thrust of a power system, the design and the processing are difficult, and the development cost is high. The single superconducting synchronous linear motor is adopted, the superconducting magnet has large size under high thrust, the refrigeration, the design and the processing are difficult, the magnet through-flow is large, the safety margin is low, and simultaneously, the quench possibly further loses the propulsion capability. The induction and synchronous hybrid power is adopted, the system reliability can be improved under the condition of ensuring high thrust, and the design difficulty and the system cost of the motor are reduced.

It should be understood by those skilled in the art that, when the positions of the suspended superconducting magnet and the sensing unit are determined respectively, the positions of the ground stator coils corresponding to the respective positions can be determined accordingly, and the present invention is not described herein again.

In summary, the power source of the launching system can be a double-side superconducting linear synchronous motor, a double-side linear induction motor, a single-side superconducting linear synchronous motor, a single-side linear induction motor or a rocket engine to boost and achieve supersonic speed.

According to one embodiment of the invention, the high conductivity metal is copper or aluminum.

For example, the ground conductor 5 may be any one of the following: copper plate, aluminum plate, copper coil, aluminum coil, etc., which are not limited in the present invention.

The above embodiment shows that the supersonic emission system based on electric pinning hybrid magnetic suspension integrates the respective characteristics and advantages of electric and pinning magnetic suspensions, and compared with a single magnetic suspension support mode, the hybrid magnetic suspension support overcomes the defects that the pinning magnetic suspension has insufficient guiding rigidity and suspension rigidity and weak anti-interference capability under high-speed and ultrahigh-speed operation, and the electric magnetic suspension must be supported by mechanical assistance under low speed, can realize stable suspension operation from low speed to supersonic speed within a full-speed range, and solves the problems of mechanical vibration, abrasion and the like caused by the traditional sliding shoe and sliding rail constraint or the electric suspension emission mode of low-speed mechanical support. And the pinning suspension structure is simple and light, a complex control system (required by electromagnetic suspension) is not required as a static and low-speed support mode, and the mass of the vehicle-mounted superconducting block is lower than that of a vehicle-mounted electromagnet, so that the effective load of the launching system can be further improved, and the structure of the launching system can be simplified. In the static and low-speed operation section, the pinning and the electric magnetic suspension work in a combined mode, so that the rolling resistance, the yawing resistance and the pitching resistance of the launching system can be further improved, and the stability and the reliability of the operation of the system are further improved. In addition, the electric and pinning hybrid magnetic suspension launching system can be compatible with various power sources such as a rocket engine, a unilateral linear induction motor, a unilateral linear synchronous motor, a bilateral linear induction motor, a bilateral linear synchronous motor and the like, can be used for hot launching and cold launching, and is strong in system compatibility and expansibility.

In general, the transmitting system according to the above embodiments of the present invention can realize stable suspension operation in the supersonic transmitting full speed range, create a low-resistance and low-vibration operating environment, and is a passive self-stabilizing suspension system in the range from low speed to supersonic full speed. The vehicle-mounted high-temperature superconducting block/stacked coating superconductor and the ground permanent magnet track form pinning suspension; the high-speed and ultra-high-speed operation is realized by adopting a vehicle-mounted superconducting magnet and a ground conductor to form an electric suspension system and realizing the full-speed-domain suspension stable operation by adopting different suspension systems at low speed, high speed and ultra-high speed.
