Reverberation chambers are used to simulate the shock and vibration loads imposed on space vehicle payloads during lift-off.
The doors to these chambers, often as tall as a commercial aircraft hangar door, require special design, fabrication and installation
considerations.
The door shown to the left laps the header, sill and jambs by one foot in order to operate
acoustic mechanical seals. The floor pit across the opening is closed by draw bridges that operate pneumatically when the
door is fully open, allowing a passageway for the transfer dollie carrying the satellite to be positioned in it's test stand
location. Interior DB levels can exceed 151!

GPS has designed,
manufactured and installed a wide range of blast doors and related specialty projects.
Projects include swinging blast doors for munitions storage facilities (Vandenburg AFB pictured above), acoustic blast
doors for C-5 engine test cells (Travis AFB), sliding acoustic blast doors for engine manufacturing facilities (GE China),
and sliding blast doors for aircraft shelters (Peace Vector, Egypt).
Shown below is a rail car designed and fabricated
especially for use as a moveable base for a jet engine blast deflector. The bases
are designed to prevent overturning of the deflector due to loads imposed by the run up of jet engines.
