Shelf Life of Composite Engines?

Shelf Life of Composite Engines?

Post by Mrkmr » Mon, 04 Aug 1997 04:00:00



I know this question has been answered lately re: BP engines, but how
about AT composite engines? I have a 24mm G55-5W single use that I bought
about 4 years ago, it has been stored in a very steady environment ever
since, with the exception of 2 summer afternoons in my range box (about
85-90 degrees). Am I still relatively safe using this engine?

Other than the likelihood of a lost rocket, you should be fine with this
motor at this age.

Composites are not susceptable to the temperature cycling that BP
motors are.  I have flown composite motors that are older than you
describe, and have seen motors flown that are significantly older than
described, so I would say your pretty safe. :-)
