About MIL-STD-810 Method 519
Method 519 tests products for use in applications where are guns mounted on aircraft or other systems to verifies your electronics or electronics packaging can withstand residual vibration, shock or noise when the guns are fired.
Crystal Group has servers mounted in gun pods on certain applications, so it’s important that our products can withstand vibration from the shock pulse, muzzle blast, random vibrations from aircraft engines, as well as the blade and its resonant frequencies and harmonics.
Typically, an application will require a certain test method; 519 has four different procedures. These tests identify damage, from an electronics fatigue standpoint, from glass components to brittle fractures within the system. You’re looking at a variety of effects that gunfire and muzzle blasts can have on the product as it is being exercised on a fighter, small weapons platform, helicopter or something altogether different.
The calibration and analysis of the data frequently involves understanding if you’re duplicating the environment for the instrumentation, which can get pretty complicated and pose challenges to complete the testing. We’ve learned to always do the endurance testing first because if the unit passes, the likelihood of passing the operational testing is strong.
You need an accurate scope of the application environment to ensure your equipment is tested to withstand the extremes of that particular type of gunfire or random vibration. With these conditions, it’s incredibly important to have a reliable, highly-available system for the application.
