2017年5月1日 · SpaceX announced that it wo develop "Falcon 9", powered by nine Merlin 1B first stage engines, to meet the needs of an unnamed government customer. Falcon 9 would be able to boost more than 9 tonnes to LEO or more than 3 …

Falcon 9 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle [a] designed and manufactured in the United States by SpaceX. The first Falcon 9 launch was on 4 June 2010, and the first commercial resupply mission to the International Space Station (ISS) launched on 8 October 2012. [14]

Falcon 9 Full Thrust is a substantial upgrade over the previous Falcon 9 v1.1 rocket, which flew its last mission in January 2016. With uprated first- and second-stage engines, a larger second-stage propellant tank, and propellant densification, the vehicle can carry substantial payloads to geostationary orbit and perform a propulsive landing ...

Falcon 9’s first stage incorporates nine Merlin engines and aluminum-lithium alloy tanks containing liquid oxygen and rocket-grade kerosene (RP-1) propellant. Falcon 9 generates more than 1.7 million pounds of thrust at sea level.

The use of this denser fuel coupled with an extended fuel tank allows more fuel to be loaded into the rocket, increasing liftoff thrust and burn time. First stage thrust is increased to 1.71 million pounds at liftoff.

2015年12月29日 · I found it quite fascinating that the Shuttle External Tank was as thin as 2.5mm. That seems very thin for a structure over 40 meters tall and weighing as much as 760 000kg fueled. I'm curious how this compares to other rockets. I know original Atlas had very thin "balloon" tanks — but how thin was it actually, and how much did it weigh?

A Turbopump feed system feeds the propellant, heated helium pressurizes the fuel tank. and dual redundant triethylaluminum-triethylborane (TEA-TEB) pyrophoric igniters for restart reliability. The two engines used in the Falcon 9 are the Sea Level Merlin engine and the Vacuum Merlin engine.

2022年7月6日 · Based on that definition, Falcon 9 has monocoque fuel tanks. The tank wall is also the outer skin of the rocket. In your question, you specifically call out the first stage LOX tank. Both stages use similar manufacturing techniques …

Falcon 9 Launches SES 9 (Updated 03/06/16) SpaceX's second Falcon 9 v1.2 with full thrust Merlin 1D engines boosted the SES 9 communications sate geosynchronous transfer orbit from Cape Canaveral, Florida on March 4, 2016.

Fuel Tank Falcon-9 tanks are made of Al-Li compound. This material is made strong and lighter than Al by the addition of Li ions. Since Lithium is the least dense elemental metal. Inside the second stage, there are two large tanks each capped with an Aluminium arch [16]. These tanks separately store liquid oxygen and rocket grade kerosene
