Testing Disciplines
Acceleration
| An acceleration test is performed to assure that Test Specimens can withstand steady state inertia loads. |
| Structural Test |
| The Structural Test is used to demonstrate that equipment will withstand the loads induced by in-service accelerations without mechanical damage. |
| Operational Test |
| The Operational Test is used to demonstrate that equipment will operate without degradation during, and after, being subjected to loads induced by in-service acceleration. Equipment to be tested is normally subjected to both operational and structural testing. |
| Crash Safety |
| The Crash Safety test is used to demonstrate that Test Specimen will not disintegrate or be torn loose from its mounts by crash accelerations. |
| Effects |
| Acceleration results in loads on mounting hardware and internal loads within Test Specimens. All elements of the Test Specimen are loaded, including fluids. Effects include: |
| Structural deflections that interfere with proper operation. |
| Permanent deformation and fractures that disable or destroy the Test Specimen. |
| Broken fasteners and supports that result in loose parts within the Test Specimen. |
| Broken mounting hardware that results in loose Test Specimens within a platform. |
| Electronic circuit boards that short out and circuits that open up. |
| Inductor and capacitors that change value. |
| Relays that open or close. |
| Actuators and other mechanisms that bind. |
| Seals that leak. |
| Pressure and flow regulators that change value. |
| Pumps that cavitate. |
| Spools in servo valves that are displaced. |
| Equipment Testing Facility |
| Our ten-foot diameter centrifuge has the capability of producing accelerations greater than those occurring in normal commercial and military aircraft service.. |
| In order to verify equipment operation during acceleration testing there are provisions to provide the equipment under test with electrical power and to monitor electronic or hydraulic function. |
| Component Testing Facility |
| High force acceleration facilities are available to subject components to acceleration levels up to 30,000 g’s |
