How does SpaceX engine work?
The power behind the Falcon 9 is the Merlin engine, which is built in-house by SpaceX. These engines burn a combination of rocket-grade kerosene called Rocket Propellant 1 and liquid oxygen. On a typical Falcon 9 launch, the first stage engines burn for 162 seconds, and the second stage engine burns for 397 seconds.
How much fuel does a Raptor engine burn per second?
The 31 raptor engines on the booster produce 212 GW of power. The 380 ISP raptor mentioned by Musk would require a 3.3 m nozzle. If they made a raptor with an 8 m nozzle (the largest that would fit) its ISP would be 394s. One Raptor engine should use 565 kg of fuel per second.
How much horsepower does a SpaceX Raptor have?
11 million horsepower1
The SpaceX Raptor is designed to supply its spacecraft with kinetic energy at a rate of 11 million horsepower1 – the equivalent of four Hoover Dams, generated by an engine weighing approximately 1.5 tonnes.
How is the Raptor engine cooled?
Raptor employs a regenerative cooling system – routing clean methane fuel from the turbine through the engine chamber and nozzle heat exchangers before reaching the preburner and turbine. By the time both propellant components reach the engine injector they are completely in the gas phase.
What fuel does the Raptor engine use?
methane
SpaceX Raptor

| Mixture ratio | 3.6 (78\% O2, 22\% CH4) |
| Cycle | Full-flow staged combustion |
How long do Raptor engines last?
Just like a regular F-150, a Ford Raptor should be good for at least 300,000 miles and probably more. Pickup trucks are built to last longer than cars and SUVs anyway, but Ford’s Special Vehicle Team designed and built the Raptor especially for heavy-duty and demanding off-road performance.
How many miles will a Raptor last?
300,000 miles
The latter is especially important, given that this truck was crafted by Ford specifically for extreme off-roading. And that’s exactly how many owners put their Raptors to use. In general, most Raptors can be expected to last up to around 300,000 miles.
What fuel does SpaceX use?
Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9 and Falcon Heavy launch vehicles. Merlin engines use RP-1 and liquid oxygen as rocket propellants in a gas-generator power cycle.
What type of rocket does SpaceX use?
Merlin is a family of rocket engines developed by SpaceX for use on its Falcon rocket family. Merlin engines use LOX and RP-1 as propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea recovery and reuse.
Where does space X take off from?
SpaceX provides military launch services from Cape Canaveral Air Force Station (CCAFS) in Florida, and also from Vandenberg Air Force Base (VAFB) in California. SpaceX is also building an additional launch site in Boca Chica Village, Texas. How Does SpaceX Work? Photo credit: Official SpaceX Photos/Flickr
What is a Raptor engine?
Raptor is a staged combustion, methane-fueled rocket engine under development by SpaceX . The engines are powered by cryogenic liquid methane and liquid oxygen ( LOX ), rather than the RP-1 kerosene and LOX used in all previous SpaceX Falcon rockets which use Merlin 1C & D engines.
