| 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 |
