Crash Survivable Memory Module

Here’s a sample of military Avionics design.

We designed a Crash Survivable Memory Module for deployment by the Navy on A-12 aircraft. A cast stainless steel, twelve faceted polyhedron was designed that weighed less than three pounds and contained an insulated, laser welded inner stainless steel enclosure containing one cubic inch of solid state memory. The unit was engineered to sustain and survive aircraft crash impact and probable fuel fire. This was the only unit in avionics community as of 6/94 to successfully complete this aggressive level of environmental testing.

Testing of unit consisted of :

  • 30 minutes of fuel fire @ 1100 degree Celsius.
  • 1,700 g impact.
  • 5,000 pound crash force.
  • 500 lb. falling from 10 feet impacting unit with .25 inch diameter hardened pin.
  • Two year immersion at 2,000 feet of sea water.
