リニアアクセラレータの発射性能の安定化と飛翔体の発射速度向上

抄録

This paper describes the improvements in launching stability and launching velocity of the linear accelerator (LAC).
The authors have designed and produced a railgun using the LAC for weaving loom shuttles. The LAC is an electromagnetic launcher which enable a projectile to be launched at a speed of more than 50m/s. It basically consists of an uni-pole linear DC motor and operates the same principle as DC rotary motors, the most difficult problem in this system being the stabilization of the current collection on the projectile.
Then we have conducted the various launch experiments. As a result, we have achieved that the carbon projectile was launched at a speed of 73m/s using double-stage type LAC.
