ABSTRACT:
A linear thruster (10) comprises a thruster assembly (15) and a compliant head assembly (100). Thruster assembly (15) includes a housing (20), a pair of guide rods (30) supported by bearings (29) in housing (20), a thrust plate (40) attached below housing (20) to guide rods 30, a power unit, such as pneumatic cylinder (50), and a thrust rod (60). Compliant head assembly (100) includes a translation block (120), a set of first leaf springs (140) supporting translation block (120) above thrust plate (40) such that translation block (120) can move forward and rearward, a compliant head (160), and a set of second leaf springs (180) supporting compliant head (160) from translation block (120) at a position below thrust plate (40) such that compliant head (160) can move left and right due to resiliency of second leaf springs (180) and forward and rearward with movement of translation block (120).
