Space x falcon heavy

Falcon Heavy ist the most powerful operational rocket in the world von a factor des two. With die ability kommen sie lift right into orbit practically 64 metric lots (141,000 lb) Falcon Heavy tun können lift an ext than twice die payload von the following closest work vehicle, die Delta IV Heavy. Falcon Heavy is composed von three Falcon 9 nine-engine cores whose 27 Merlin engines together generate much more than 5 million pounds of thrust punkt liftoff, equal kommen sie approximately eighteen 747 aircraft.

Three cores make nach oben the zuerst stage of Falcon Heavy. Ns side cores, or boosters, are linked on die nosecone, die interstage, and on die octaweb. Soon after liftoff die center main point engines room throttled down. After ns side cores separate, the center main point engines throttle zurück up to full thrust.

Falcon Heavy’s erste stage incorporates 27 Merlin engines across three aluminum-lithium alloy rocket cores containing flüssig oxygen and rocket-grade kerosene (RP-1) propellant. Falcon heavy generates more than 5 million pounds des thrust punkt liftoff.

THRUST at SEA LEVEL22,819 kN / 5,130,000 lbf
THRUST an VACUUM24,681 kN / 5,548,500 lbf

The Falcon Heavy zuerst stage ist equipped v 12 landing legs (4 on every booster) made of state-of-the-art carbon fiber through aluminum honeycomb.

All 12 landing legs room stowed along the side des each booster until nur prior kommen sie landing.

Merlin Vacuum functions a bigger exhaust section und a substantially larger expansion nozzle zu maximize die engine’s efficiency an the vacuum des space. Its combustion chamber is regeneratively cooled, while the expansion nozzle ist radiatively cooled. At full power, ns Merlin Vacuum engine operates with die greatest performance ever for in American-made hydrocarbon rocket engine.
