Launch Equipment Test Facility (LETF)
Capabilities: LETF Capabilities Document
The LETF’s unique facilities/services include:
- 600-ton test fixture for multipurpose proof loading of large testing articles in either the vertical or horizontal orientation, and in either tension or compression
- Two independent Vehicle Motion Simulators recreate all of the motions that a launch vehicle (6 Degrees of Freedoms) will experience from rollout to the launch pad through the first second of launch
- Qualification testing of umbilical systems in both pre-launch and launch environments and launch vehicle access arms in pre-launch environment
- Verification of operational procedures, clearances, disconnect systems performance and margins, and vehicle loads throughout the vehicle processing flow
- Ability to create LN2 and LH2 flows to subject test articles to cryogenic temperatures and pressure
- Ability to perform component testing using LN2, LH2, GN2, GHE, water or hydraulic fluid
- Vehicle Stabilizer Test Fixture — motion control system capable of simulating large biaxial load profiles
- Data Monitoring and Acquisition – Data acquisition system/software and video system available in fully equipped control room with test team communication system
- Mobile Instrumentation Support – mobile, self-contained control room with National Instruments PXI-based Data Acquisition System, operates off facility or generator power
