Space Hardware Testing

Experior Laboratories specializes in creating high-performing and demanding random and direct-field acoustic vibration, Pyroshock, thermal vacuum and accelerated life fast-ramp temperature tests associated with rocket launches and landings, stage separation events, payload deployments and in-orbit satellite and spacecraft operations. All these capabilities are performed in an ISO 8 / Class 100,000 cleanroom environment. Experior Labs has the capabilities and expertise to tackle any size test article and payload, ranging from components to sub-systems to large and heavy full size space craft, satellite, rocket engine, reflector, etc., in our 11,000 square foot dynamics testing facility that offers a 33 foot ceiling height and a 15 ton crane for easy installation and maneuvering of the test article.

As one of the leading independent test laboratories in North America, Experior Labs is recognized for its superior customer service, consistent on-time delivery, project management by experts and end-to-end accountability.

Vibration Testing – Launch Simulation
Astrobotics Griffin Structural Test Model (STM)
Direct Field Acoustic Testing – Launch Simulation
Astrobotics Griffin Lunar Lander (STM)
Experior Labs recently completed the testing of the Astrobotics Griffin Lunar Lander Structural Test Model. The completed Griffin will be delivering NASA’s water-hunting rover VIPER to the Moon in 2023. It has five times the carrying capacity of Peregrine and can accommodate larger payloads like rovers the size of a compact car.
Direct Field Acoustic Testing (DFAT) is a high intensity acoustic vibration testing method mainly for aerospace which offers a time and cost saving alternative to conventional reverberation chamber testing.

High Performance Vibration Testing for Large and Heavy Test Articles

The newly installed system combines two test industry expert components, a new Unholtz Dickie T4000 vibration system and a TEAM T-Film Bearing slip table.

The TEAM T-Film bearings have several benefits overs standard oil film and linear bearings. The unique inverted T shape of TEAM bearings provides improved stiffness, load transfer and improved moment transfer to the reaction base. This minimizes slip plate deflection and cross axis vibration, as well as allows for test articles with a much higher overturning moment. The hydrostatic bearings have significantly increased load capability, meaning the table can accommodate much heavier test articles.

Acceleration Testing

The main advantage of the Sine Burst is that it is performed on a vibration system, the same vibration system that performs other tests such as random and/or sine sweep vibration and shock testing. Further, test article sizes can be much larger and heavier than in a Centrifuge. Performing all dynamic tests on the same vibration system reduces test costs and time.

Pyroshock

Pyroshock testing simulates the high G, high-frequency shock environment associated with pyrotechnic events, such as rocket stage separations. These are sometimes called “SRS Shock” tests, as they are specified with a Shock Response Spectrum (SRS) profile. This profile is a representation of the maximum predicted acceleration of a system across a range of assumed natural frequencies.

Experior Laboratories’ Kinetic Impact Pyroshock Simulation (KIPS) test systems are able to simulate near and midfield Pyroshock, experienced by components closest to a pyrotechnic event, using a high-speed impact to excite a tunable resonant beam. Adjusting the impact force, location and damping, this platform allows for highly customizable shock generation and the pneumatic systems allow for quick setup and reset.

Adjustable resonance allows boosting acceleration in only the desired frequency range. For shocks with a specified Te (event duration), adjustable muzzle velocity, impact mass, and custom damping materials allow us to customize shock duration while meeting acceleration requirements.

The KIPS test systems offer short transients, narrow differences between positive and negative SRS traces, and a uniform shock input that allows for near-equal measurements at multiple fixture mounting points.

Experior Labs has designed a wide variety of custom shock platforms and fixtures, and we’ve used frequency analysis software to identify mode shapes and resonant frequencies, which lets us prevent cross-axis acceleration and ensure that units are not over-tested.

Horizontal Shock System

Experior Laboratories’ new horizontal shock system represents a dramatic increase in the size of units that can undergo SRS Shock testing.  Parts mount to a 40”x40” platform that matches directly with slip tables on our high power T2000 electrodynamic shakers, allowing a seamless transition from vibration to shock. An internal compressor boosts impactor pressure high enough to reach 5,000G on parts over 500lb.  Chromed precision guide rods ensure the platform travels only in the direction of the applied shock. Programmable electromagnetic clutch brakes grab the table after impact to allow resonance and prevent secondary impacts. The system allows adjustment of padding, pneumatic parameters, and brake timing to adjust knee frequencies between 250Hz and 3000Hz

Shaker Shock

Experior Laboratories performs SRS Shock testing with levels up to 5000 G on the T2000 Shakers, making Experior Labs the industry leader in SRS Shaker Shock. Most test labs cannot offer Shaker Shock testing above 500 – 1,000 G SRS due to risk of shaker armature damage.

Thermal Vacuum

Experior Laboratories’ vacuum test chambers are designed to meet the harsh requirements of space conditions. Experior Labs is capable of simulated space along with repeated cycling between high and low temperature extremes – all while providing test data to better assess likely flight mission performance and function.

Fast Ramp Temperature Testing

Experior Laboratories has several accelerated thermal chambers with high-flow blower motors and liquid nitrogen boost designed to transition temperature as quickly as possible, and are ideal for tests with demanding ramp rates.

Cryogenic
Temperature Testing

Experior Laboratories test facility can simulate extreme low cryogenic temperatures for aerospace, fiberoptic and electrical applications. Our cryogenic chambers have liquid nitrogen and liquid helium tanks piped in for rapid chilling and freezing temperatures.

Many space components require Cryogenics Testing for parts and instruments exposed to the extreme temperatures in rockets and orbit.
