Project
409 Static
Post-flight Analysis
- Alberto Gassol and I performed 9 static tests ranging from 1" to 2" in diameter. The 1" engines were made with a different brand of chemical than Alberto was used to using and was probably the cause of the first four failures. The 2" engines were an attempt to make a reliable K engine and also to confirm the odd results from the 326 static tests where the 60/40 engines performed better than the 65/35 engines. All four static tests were successful and once again the 60/40 engines produced around 100 Ns more than the 65/35 engines. Alberto's fifth static worked well producing a maximum thrust of 38 pounds.
Construction
- Similar to the J300 engine except a 24" casing was used instead of 18".
Pros
- A good formula for a reliable K engine.
- Four K's will make a low power M set for the next Sea Launch in August.
- Easy to construct.
- Low cost.
- Each engine can be made in about 1 hour and fueled in 90 minutes.
