DerrickM,
That is awesome that you are interested in engines in general. The pulse-jet is, as you know, a simple engine to fabricate and test. However, the design can be quite tricky to get reasonable performance. Your question about operating frequency is determined by many factors; the...
EdDanzer,
We started out looking at extracting power through a reciprocating generator design, but most people wanted a mechanical extraction system in order to reduce size and weight. We designed and fabricated a mechanical conversion unit that changes reciprocating motion to rotary motion...
tbuelna,
Do you know if TACOM is still working on the TRC engine? I do know they are working on the OPOC with DARPA. I believe they are trying to clean up the emissions and get some higher performance (i.e. lower sfc) out of that 2-stroke.
Research is both scary and thrilling sometimes, but...
I have measured between 1800-2500 psia in the chambers. As others have mentioned, this is the max design pressures for most commercial CI engines out there, based on thermal and structural limits.
tbuelna - was that opposed piston engine you worked on for TACOM the OPOC by chance? I'm curious...
