What Does OHGVT Stand For?

OHGVT stands for Orbiter Horizontal Ground Vibration Test

The Orbiter Horizontal Ground Vibration Test (OHGVT) is a critical assessment procedure used to evaluate the structural integrity and dynamic response of spacecraft in a controlled ground environment. This test simulates the vibrational conditions that the orbiter may experience during launch, ensuring that it can withstand the forces encountered in space. By conducting the OHGVT, engineers can identify potential resonance issues and validate design specifications, thereby enhancing the reliability and safety of the spacecraft before its mission.
