PROPELLANT GRAIN CUTTING ASSEMBLY

摘要

A cutting assembly (10) for cutting propellant from a rocket motor. The cutting assembly (10) includes first and second cutting wheels (18, 20) and secondary cutters (22) mounted to a mounting head (14). The cutting wheels are mounted for rotation about am axis transverse to the axis of rotation of the mounting head. Each cutting wheel includes cutting blades extending outwardly from a rim (24). The cutting blades each have a cutting edge for cutting in a direction normal to the axis of rotation of the mounting head. The amgle of orientation of the cutting blades of the second cutting wheels (20) is opposite in direction to the angle of orientation of the cutting blades of the first cutting wheels (18). The secondary cutters (22) include a circular cutting blade for making cuts transverse to the cuts made by the first and second cutting wheels (18, 20).
