Development of metal corrugated/flexible hoses
Objectives

Objective(s): ​

  • Flex hoses design phase and derisking activities (including breadboard manufacturing and tests) to achieve a TRL = 6​
  • Pressure drop tests​
  • Resistive torques characterization​
  • Vibration tests​
  • Static characterization
Description

Achievements and status: ​

  • TRL = 6 achieved for three different type of hoses (for different ranges of movement)​
  • Pressure drop preliminary measured​
  • Resistive torque characterized in various conditions (temperatures, pressure)​
  • Tested in relevant mechanical environment (vibration): test permits to highlight the need of some system level design improvements (i.e. retaining system for the hoses during launch) ​

Benefits: ​

  • Improved knowledge of the ¾” flexible hoses (previous limited to smaller diameter) behavior in relevant environment
