Just to add to this fine comment. I had a long discussion in the past regarding testing of new engines and how it was done prior and during the war by various countries. US is famous for its 150-hour type test. Scope of my research was Japanese testing which is kind of similar. You can read it here: http://www.enginehistory.org/Piston/...gTesting.shtml

Especially take a notice of endurance tests and how it was comprised of multiple runs of engine at idle, take-off rating, idle, rated rating, etc. Such tests lasting 100 + hours cover entire scope of engine operation even in extreme conditions.

As for the US, from the mid-1930s through WWII, some version of AN-9502 dictated how aircraft engines were to be tested by the U.S. Army Air Corps/Forces and the U.S. Navy. These tests typically began with calibration runs where the engine was run in a test cell under the same conditions that would be used during endurance testing, with data collected at all conditions and power settings. Then the 150-hour type test began. Like Japanese testing, this consisted of running at various power settings in repetitive cycles.

The difficulty arises because AN-9502 was constantly changing, and often the exact tests were negotiated between the procuring agency and the engine manufacturer. I have never seen a complete copy of any version of AN-9502.

MIL-E-25111 ultimately replaced AN-9502 around 1955, and was used for reciprocating engine testing until it was retired.

How come? What Hiromachi posted, while highly interesting per se, has absolutely nothing to do with what ED may, or may not, do. Would absolutely love a Pacific module myself though, mind you; but who's going to do them Hellcats and Zeros and all that stuff then?

If ED is going to make the Zero. He'll have to learn how to work with balsa wood.
