Delserro Engineering Solutions (DES) – Recent Projects (Spring 2021)

DES — Wed, 10 Mar 2021 21:02:55 +0000

Recently, DES has been very busy working on multiple space and aerospace test programs. We can’t discuss too many details due to the sensitive nature of the products. Some highlights are:

SpaceX

We performed Design Verification Testing (DVT) for components that are used for the SpaceX Falcon 9 rocket program. The testing consisted of acceleration, shock and vibration. Falcon 9 is a partially reusable two-stage rocket for the reliable and cost-efficient transport of satellites and SpaceX’s Dragon spacecraft.

NASA Orion

We completed Pyroshock Testing on our Mechanical Impact Pyroshock Simulator (MIPS) and random vibration testing on our ED shaker for equipment that will be used on the NASA Orion spacecraft. Orion is NASA’s new spaceship that will take astronauts into deep space including the Moon and Mars.

Sierra Nevada Dream Chaser

DES has been selected to perform Pyroshock Testing on the Dream Chaser program. The Dream Chaser is being developed by Sierra Nevada Corporation Space Systems. It is a reusable lifting-body spacecraft similar to the space shuttle.

Boom Supersonic

DES completed qualification vibration testing for components that will be used on the Boom Supersonic aircraft. Boom Supersonic is building passenger airliners that will fly at supersonic speeds significantly reducing travel time. The testing was to RTCA/DO-160G.

And much more…

We just added a Thermal Vacuum Chamber or TVAC that can perform Space simulation Testing. DES’s TVAC can achieve high vacuum levels and apply hot and cold temperatures simultaneously with high vacuums.

However, that is not all that we are working on. We recently completed HALT and Reliability Testing on medical products and transportation products.

What sets DES apart from other labs is our in depth experience and technical capability to understand and reproduce the most complicated vibration and shock profiles. DES continues to perform the most complex vibration and shock tests on products that are used in outer space, rockets, missiles, automotive & truck environments, military environments, hospitals, etc.

Qualification Testing on Aerospace Connectors

DES — Fri, 29 Jan 2016 16:57:24 +0000

DES recently performed qualification testing on aerospace connectors which involved combined temperature and sinusoidal vibration testing, random vibration testing and shock testing. Combined temperature and sinusoidal vibration tests were performed per EIA 364-28F. EIA 364-28F required test conditions of 10-2000 Hz, 20G maximum acceleration sweeps at temperatures of -54°C and 200°C over the course of 4 hours per axis. Random vibration tests were also performed per EIA 364-28F. Random vibrations at 50-2000 Hz, 46.3 Grms were applied to the connectors for 8 hours per axis. The random vibrations were applied at room temperature. Finally, the connectors were subjected half sine shocks per EIA 364-27C. The shock requirements were three shocks per polarity, per axis at 300G over the duration of 3msec. A sample shock plot can be seen in Figure 1.

These tests demonstrate the unique capability of Delserro Engineering solutions. Not many labs are equipped to perform combined temperature and vibration testing at the extreme temperatures of this test or are able to produce the high levels required for random vibration and shock testing.
