A-8: 1 TRMC T&E/S&T BAA Enclosure 1.4: page 1 Return to Table Domain 2 – Threat Induced Effects Fabrication of a High-G Centrifuge for Inertial Measurement Unit (IMU) Testing The Nuclear Environments Test environment requires an affordable and sustainable high-G centrifuge to conduct successful testing. The centrifuge must be capable of testing future high-G and high-accuracy passively cooled strap-down IMUs. Although high-G and precision centrifuges exist, achieving an extremely high precision/high-G centrifuge with counter-rotation for the element under test has proven difficult to realize. The precision requirement presents challenges necessary to establish inertial environment “truth” that can be compared with the output from the IMU under test. The Government seeks a solution that ensures precision and reliability during IMU testing.

Desired Objectives:

Technologies are needed to:

· Enhance testing accuracy to minimize radius and rate errors, such as employment of an arm radius of 5-8 feet.

· Provide a counter-rotating platform (CRP) to keep gyros and accelerometers from saturating and accumulating error.

· Permit a test item acceleration capability of 300 g or higher.

· Provide a micro-inch and arc-second level precision in measuring position, rate, and attitude.

· Allow multi-axis test article repositions by control system or remounting to achieve maximum observability of all sensors inertial error terms.

· Provide continuous power and signal connections to the IMU during operation.

· Provide a safety built-in test (BIT) to ensure desired probability of detected failure or impending failure.

· Minimize vibration exposure to the IMU during operation.

· Provide a design that incorporates the required facilities and sustainment plan for long-term use and affordability.

As part of this solution, the Government also seeks to identify Risk Areas for Transition, such as sustainment plans and facility requirements.
