 ARCA new engine Posted on: Sat Aug 18, 2012 2:34 amHi Guys,
Just wondering if anyone with propulsion experience has any thoughts on their "Executor" thing? Considering their long and storied history of making a lot of noise and not doing anything, I'm pretty skeptical. The thing they posted pics of looks just like an engine cast not anything close to functional. Am I right or is this time different? _________________ Cornell 2010- Applied and Engineering Physics Software Developer Also, check out my fractals |

Re: ARCA new engine Posted on: Sat Aug 18, 2012 10:06 pm I assuming what is in the pics is just the engine "core"; nozzle, thrust chamber, and turbopumps, without any of its ancillary systems or controls.
It would be nice if someone had built an engine that clean and simple that had the performance claimed. But I won't believe it until the test fire a prototype and publish the results. It does look pretty cool though. Sorta Steampunkish. |
