Description

Variable magnetic pole linear accelerator

Technical field

The present invention relates to the linear accelerator in a kind of electromagnetic propulsion technical field, relate in particular to a kind of variable magnetic pole linear accelerator; Specifically, relate to the structure that composition becomes the electrical supply rail and the synchronous core of magnetic device.

Background technology

Along with the develop rapidly of aeronautical technology, at present, the domestic rocket that can utilize starts the punching type aircraft, but rocket can only use once the cost height.And developed countries such as the U.S., France utilize B52 aircraft+rocket to start the punching type aircraft, and are more advanced than China, but because of the use of B52 aircraft repeated multiple times, thereby it is very low to start total cost, but still undesirable; In order to find high-tech with practical value, the U.S. has planned development test punching type aircraft startup in three stages new technology, i.e. X-43A, X-43B, X-43C.In a word, the U.S. studies stage by stage and its objective is:

(1) starting punching type aircraft one-tenth should be very low;

(2) fail safe is good;

(3) linear thrust is big;

(4) space rate height has 2～5 overtone speed (M);

(5) electrical source of power requires very little;

(5) no difficulty is easily gone in operation.

The U.S. has entered second stage at present; Phase III still can't carry out, difficult labour.

Summary of the invention

The objective of the invention is to overcome the shortcoming and defect that prior art exists, and a kind of variable magnetic pole linear accelerator is provided.

The object of the present invention is achieved like this: the synchronization principles of main utilization " linear accelerator " and the mutual grafting of the expansion of DC motor running principle form.

As Fig. 1, Fig. 2, the present invention mainly is made up of change magnetic device 1, orbit 2, motion electromagnet 3;

Become magnetic device 1 and be provided with orbit 2, motion electromagnet 3 is arranged on orbit 2;

Described change magnetic device 1 is the 1st electromagnet the 1.1, the 2nd electromagnet the 1.2, the 3rd electromagnet 1.3 along linear array ... N electromagnet 1.N; The direction of the magnetic pole of each electromagnet is to make motion electromagnet 3 along the direction of orbit 2 continuous accelerated motions (among Fig. 1 for to the right).

Operation principle of the present invention is:

As Fig. 1, suppose that motion electromagnet 3 upper ends are the S utmost point, then the upper end of the 1st electromagnet 1.1 should be the S utmost point, and the upper end of the 2nd electromagnet 1.2 should be the N utmost point.According to the same sex is repelled each other, there is a natural attraction between the sexes principle as can be known, then motion electromagnet 3 leaves 2nd electromagnet 1.2 motions of the 1st electromagnet 1.1 to the right.

As Fig. 3, the upper end strain of crossing the 2nd electromagnet 1.2, the 2 electromagnet 1.2 when motion electromagnet 3 one is the S utmost point, and the upper end strain of the 3rd electromagnet 1.3 is the N utmost point.According to the same sex is repelled each other, there is a natural attraction between the sexes principle as can be known, then motion electromagnet 3 leaves 3rd electromagnet 1.3 motions of the 2nd electromagnet 1.2 to the right.

And the like, make motion electromagnet 3 along the continuous accelerated motion of the direction of orbit 2.

Feature of the present invention and technique effect:

1, the present invention utilizes direct current machine to launch principle, make two magnetic poles near the time interaction force maximum (axiom) that produced, thereby linear thrust is big.

2, because introduced the synchronization principles of linear accelerator, magnetic pole change-over time is zero, and space rate is fast.

3, the preliminary experiment by power is measured, every 12V automobile batteries can produce the linear thrust of 10Kg.If it is 15～20 tons that certain punching type aircraft needs thrust, then need automobile batteries 1500-2000 only; Electrical source of power of the present invention requires very little, just 8～10% of U.S.'s electromagnetic propulsion test (with the power contrast of Lauren).

4, operating cost of the present invention is low, can repeatedly use (rocket can only use once).

5, security performance is good, can not explode.

6. the present invention is an open type, processing ease.

This shows that the present invention is the desirable technique that starts the punching type aircraft, is the high-tech that fills the domestic gaps, surmounts U.S. X-43C, thereby, can reduce the start-up cost of punching type aircraft greatly, and fail safe is good, economical and practical, the cost performance height, defense spending is saved in useful national defense construction; Realize catching up with and surpassing the target of U.S.'s high-tech technically.
