Post-flight Analysis
- This series of tests was done in an effort to determine if Glycerin was evaporating towards the end of the engine casting process causing failures with the new K engines. Currently in the J300 engines there is 3.5% glycerin in the fuel mix and if any evaporates, the 65/35 fuel will crack and the engine will fail. Several engines were tested with 5% Glycerin which seems to work fine and one engine was tested with 7% Glycerin which greatly reduced power output. Four J300 engines were also tested to see if adding the Glycerin at the end or beginning of the fuel casting process made any difference.
Construction
- Four standard J300 engines with 18" casings and four prototype K engines with 24" casings.
Pros
- All engines worked well, none exploded.
- It seems that some Glycerin does evaporate towards the end of the casting process and if not accounted for by added extra Glycerin in the beginning of the casting process to compensate, the engines will fail.
Cons
- More tests are needed to clarify any conclusions gained from today's tests.
