Abstract :
A gas gun accelerator (GGA) based on magnetodynamic suspension (MDS) can repeatedly launch heavy objects. An object is stably suspended in the magnetic field and flies inside the launch tube without any support and friction, keeping a small gap (<0.01 m) from the tube´s inner surface. The launch tube is cut into two parts, joined on each side by special cameras with slits between the upper and lower parts. Steel cores of the MDS stator are installed inside each camera. Two holders with levitator magnets are attached to the object on both sides. To start launching, an object is inserted into the tube and is accelerated by pressure of combustive gases burning behind the object.
