Space Shuttle Discovery
This was the twenty-sixth flight of Invocon hardware on the Space Shuttle. During STS-120 mission, the Discovery crew delivered the Harmony module to the International Space Station. Two IVC systems were present on the orbiter.
Below is a list of the IVC systems that were present on Discovery during the mission. The EWB MicroTAU-WLE system is the IVC system used for detecting impacts on the leading edge of the Orbiter’s wing.
|Wing Leading Edge
Enhanced Wide-Band Micro-Miniature Tri-axial Accelerometer Unit
This is the seventh flight of the EWB MicroTAU system, a high-speed data acquisition network for dynamic acceleration sensing and recording. On STS-120, 44 units were used to detect, locate, and characterize impacts on the RCC panels on the wing leading edge.
Micro-Miniature Strain Gauge Unit
Twelve Invocon MicroSGU™ sensors were installed in the engine compartment to measure the stresses imparted to the trunnion arms on the Space Shuttle Main Engines (SSMEs).
