Large "Length over Diameter" Projectiles

During projectile transit through the acceleration spiral, the "evaporating surface" shown above vaporizes and creates a gas bearing region which separates the projectile from the spiral surface. 
Please also see  Publication Link for additional description.  

The above 2 images show the straight "locked" flight position (left) and the "unlocked" firing position (right).  Large L/D projectiles with rigid segments and flexible connections can conform to a curved track for acceleration in a Slingatron.  At exit the projectile traverses a straight section of tube in which alignment of the segments allows pressure-loaded or small "charge fired" rods to be driven into neighboring segments to lock the projectile into a rigid straight condition for flight.
Images above and below show detail of spring detent locking mechanism which will lock projectile segments in "straight" or "flight" position upon projectile launch.
