MIL-STD-810 Vibrations Jet Aircraft Exposure Level

MIL-STD-810 Vibrations Jet Aircraft Exposure Level

MIL-STD-810 Vibrations Jet Aircraft Exposure Level

(OP)
Hi,

Does anyone know the Exposure Level for a category 12 Jet Aircraft?

I need to qual a off the shelf product so I would like to test to the 810 "recommendations" of "guides". All other categories seem to have "recommendations" when no spec is available.

Thanks!!!
Derek

Thanks for the response!

Category 7 is for Transportation - Cargo. My product will be Operational - Installed Materiel. I will actually be testing for categories 12, 13 and 14 (jet, propeller and helicopter). Categories 13 & 14 are well defined in MIL-STD-810G but not category 12.

Doing a search I noticed many products list the vibration as Category 12, 15-2000Hz, Wo=0.1g^2/hz, 12g rms.

DO-160C, Section 8 suggests Wo=0.08g^2/hz for products mounted in the fuselage of a jet.

This math is correct but where / why does the industry use Wo=0.1g^2/hz???
