Centrapetal Projectile Accelarator
The surface of the moon is covered by the hard regolith. To penetrate this hard layer, it is necessary to beam the projectile with high velocities to the surface of the moon.
Working: At first, the extensible elastic string containing the projectile is attached to the motor. When the electric current is made to flow through the circuit, the motor begins to rotate. The string unwinds and starts to revolve under the influence of the centripetal force given by F=MV^2/R and an acceleration of V^2/R where M is the mass of the projectile, V is its velocity and R is the length of the string. The increase in the power of the motor would increase the acceleration further, till the string containing the projectile touches the internal surface of the accelerator. When the projectile reaches the desirable velocity, and the centripetal projectile accelerator aligns with the launch angle, it is detached from the string released through the tube. The projectile travels in straight line through the tangential component of the centripetal projectile accelerator as shown in the above image.
