ENGINE TEST STAND DESIGN LOADS

ENGINE TEST STAND DESIGN LOADS

ENGINE TEST STAND DESIGN LOADS

(OP)
hi

Does anybody know of any specs or standards, or design codes for engine test stands, such as might be used in test cells.  Engine is a large turboprop.

I am mainly interested in load cases.

Thank you

Graham Murphy

RE: ENGINE TEST STAND DESIGN LOADS

Graham,

If you are talking about a turboprop run up stand then a good place to start is with the negine interfece control document or manual.  That will give you the normal (zero) G loading condition for the mounting points and the expected loads in the event of a full power seizure.

A test stand should be able to absorb these loads without suffering any major damage ar rupture of fluid lines.  The last thing you need followning a major engine failure on test is a ruptured fuel line, BTDT - not pretty.

If you are looking for a good basis to build from ( I assume you intend to use a water brake system) try looking at the design specs for something like the AIRLOG run up trailers.  They may already have a mounting adaptor designed for your engine type or something similar.
