Fundamental study on reconnection Electromagnetic Launch Assist technology1

With the ever-increasing cost of getting to space and the need for safe, reliable, and inexpensive ways to space, many researchers are taking a look at technologies that will get us to space. One of these technologies is Electromagnetic Launch Assist (EMLA). This is the concept of providing the rocket with an initial velocity by using electrical power from ground sources to save fuel and cut down cost. In this paper, the shortages of chemical launch and the fundamental work process of reconnection electromagnetic launcher is described briefly, the fundamental performance of simple reconnection electromagnetic launcher and the effect law that the parameter of driving coil and planked projectile pose on their fundamental performance, and all of these will be a basis of the design for reconnection electromagnetic launcher. And then, based on the features of simple reconnection electromagnetic launcher, the simulation and research for simple system of reconnection EMLA are put forward. The result shows that, using this system, we could make the load of about 10000kg accelerate to the velocity of 180m/s with 32 times the acceleration of gravity and then save cost of launch vehicle.
