I do not think Unisys is around anymore. The EMI lab is closed. BAE on county line Road in Hatfield PA used to do outside testing. (215) 996-2737

A better analogy would be putting holes in a parachute. Dive bomber air flaps are completly different problem.

I have used NU lab for both RTCA DOD-160 and Mil-STD-167 vib testing. NU Laboratories Inc. 312 Old Allerton Rd. Annandale NJ. Telephone: 908-713-9300 Fax: 908-713-9001 They are similiarly priced to NTS.

I have had good results using bondo putty to cover spot welds. Also, a powder coat with a rough finish will hide it better than a smooth one. Mike is right about the spot weld settings. There is nothing worse than having a welded assembly fall apart in your hands and trying to identify...

You can test your inventory for hydrogen embrittlement. See the ASTM F519-06e1 Standard Test Method for Mechanical Hydrogen Embrittlement Evaluation of Plating/Coating Processes and Service Environments for details. It is a fairly quick (4 days max, often times 2-3 hours) and dirty way to...

Hello, Is your application in fresh water or salt water? Matt Evans

In general thermal epoxies have a thermal conductivity of around 5 W/m*K. An aluminum braze allow will have a thermal conductivity of around 150 W/m*K. Thermal resistance R Material thickness, L Thermal conductivity, k Cross sectional area, A R = L/(k*A) In order to make up for the lower...

For a first pass, you can also try the lumped capacitance method. You can work it out on paper, and it will give you reasonable results. You will need to research what the convection constant (h = 5-25 W/M^2*C for free convection in electronincs) for acetonitrile to glass.

Make sure that loads and restrainsts are applied to the same surface that you used to generate the shell.
