Purpose:
Universal Joint is used for gimbal joint in Rocket engines
Criticalities involved are:
These Joints must have least resistance/friction, and minimal slack to ensure precise control/gimballing of the rocket engines.
Tolerances & Accuracies involved are:
+/- 2 Microns
Number of Parts involved are:
16 parts
Special Operations Involved
Precision CNC Machining, Jig Grinding, Rubber 'O' Rings, Jig Boring, Precision Boring, Precision Grinding, Clean Room Assembly, Load Testing, Backlash Test.
Failure to perform:
Can lead to errors in orbit of the rocket - Mission Failure.
