Application: Interplanetary Exploratory Vehicle
Problem: Spring must operate in extreme temperature range, be fully corrosion-resistant, and not damage a softer base material.
The MWI Solution:
- Designed an Inconel
® 718 spring, optimizing for the clearance available
- Worked with the customer to develop a complete qualification testing procedure
- Performed tests at almost absolute zero and in high temperatures
- Measured all directions of the force developed by the spring to know the stresses that would be applied to the base
The prototype spring passed all qualification tests, production springs were produced and are currently functioning successfully on Mars.
