The Merlin engine is a lower stage gas generator cycle RP-1 kerosene/liquid oxygen Gas-generator cycle (rocket) rocket engine. The Merlin engine was developed for use on the Falcon I and Falcon V rockets by SpaceX and is designed for sea recovery and reuse. == Engine details == === Performance === *Sea level thrust: 71,500 lbf (318 kN) *Vacuum thrust: 85,000 lbf (378 kN) *Sea level Isp: 261 s (2.6 kNs/kg) *Vacuum Isp: 310 s (3.0 kNs/kg) *Thrust-to-weight (fully accounted): 94 Note: performance specifications subject to change upon further testing === Operations === *Fuel: RP-1 rocket grade kerosene *Oxidizer: Liquid oxygen == Sources and external resources == *[http://www.spacex.com/index.html?section=falcon&content=http%3A//www.spacex.com/falcon_engines.php SpaceX Falcon engines page] *[http://www.wired.com/news/space/0,2697,66308,00.html?tw=wn_tophead_1 Race for Next Space Prize Ignites]: Wired article describing successful test firing Rocket engines
Is it true that the Merlin engine uses the same technology as NASA's (cancelled) Fastrac project? --User:NeuronExMachina 03:19, 5 Aug 2004 (UTC) : I don't know all of the details, but here's an article on [http://www1.msfc.nasa.gov/NEWSROOM/background/facts/fastrac.html Fastrac] and one on TRW's [http://spaceflightnow.com/news/n0009/26trwpintle/ Low Cost Pintle Engine (LCPE)] for future reference. Both engines were designed at roughly the same time and Tom Mueller, now VP of Propulsion at SpaceX, was on (led?) the LCPE team for TRW. Because of this, I would expect that Merlin would look more like LCPE than Fastrac. The merlin engine has roughly the same thrust as Fastrac and about 1/10 the thrust of LCPE. I guess I wouldn't be surprised to see a SpaceX design that looks an awful lot like LCPE coming out in the future.User:Dschmelzer 17:42, 5 Aug 2004 (UTC) : There's some discussion on the a-rocket mailing list that indicates SpaceX may have associated the turbopump with the Fastrac design, but that it's actually a clean sheet design. This level of detail is well beyond my expertise though. User:Dschmelzer 19:27, 23 Aug 2004 (UTC) Should this article be at Merlin (rocket engine), sort of like Kestrel (rocket engine)? --User:NeuronExMachina 07:42, 18 Aug 2004 (UTC)
