![]() This pattern reduces the booster’s length and weight, and simplifies the rocket’s design and assembly. The engines are configured with eight engines surrounding a center engine called the “Octaweb” pattern. Falcon Heavy's first stage at sea level generates around 22,819 kilonewtons of thrust. ![]() Its primary purpose is to ascend to orbit with a high thrust to carry a heavier payload. The center core has thicker tank walls and the booster separation system, while the two boosters are structurally identical.Įach core comprises nine Merlin gimbaled engines for a total of 27, and aluminum-lithium alloy tanks containing high-density subcooled liquid oxygen (LOX) and chilled rocket-grade kerosene (RP-1) propellant. The side boosters are linked to the center core at the nosecone, the interstage, and octaweb. The first stage of the Falcon Heavy is three Falcon 9 first stages with reinforced cores. The Falcon Heavy comprises four main components: the first stage rocket with one central core and two boosters, the interstage, the second stage rocket, and the payload fairing. The engines perform a "boostback burn" to bring trajectory toward the landing site, deploy grid finds, "entry burn" to slow down the first stage, aerodynamic guidance, and then "landing burn" for a precise landing as it deploys landing legs and lands upright. The three first stage cores fly to land or a drone ship using a combination of reaction control thrusters, forward-mounted grid fins, and thrust from one or three of the main Merlin engines. The ejected central core also executes a flip maneuver to reorient itself using its cold gas thrusters. The following process is the same as the Falcon 9 except with two additional boosters. The payload fairing is ejected once positioned in its final orbit, and shortly after the reignition of the second stage. Following the separation of the central core, the second stage ignites and transports the payload to a parking orbit before igniting again to place it in its final orbit. The center core burns for 187 seconds before it is ejected. The two booster cores perform a flip maneuver to reorient themselves using their cold gas thrusters and begin their descent to Earth. Once the side boosters burn for 154 seconds at maximum thrust and separate from the core, the center core resumes full thrust. After a few seconds at full throttle by the center core, it throttles down to conserve fuel and prolong burn time. The 27 gimbal-mounted engines handle pitch, yaw, and roll control. The Falcon Heavy takes off at full thrust of the center core and side boosters. Since the rocket's most valuable and expensive parts are reused, Falcon Heavy substantially reduces space access costs for heavy cargo. Similar to the Falcon 9, the first stage boosters undergo a strict inspection for any damages, replacement of some individual parts, and a pre-launch static fire of all 27 Merlin engines before its next launch. After transporting the payload into orbit, the first-stage central and outer boosters will withstand reentry to Earth, land safely, and be prepared for the next launch with minimal refurbishing. It is designed and built for the reliable and safe transportation of heavier cargo into Earth’s orbit. SpaceX's Falcon Heavy is a reusable, two-stage rocket based on the Falcon 9 design with two additional boosters. Governments and private companies worldwide have struggled with the impracticality of building an expensive rocket for a single mission. It employs the identical second stage and payload fairing as Falcon 9.Īccess to space is a complex and costly endeavor. It is a partially reusable composite rocket with a reinforced Falcon 9 first stage as the central core, and two added first stages as side boosters. Gimbaled engine and nitrogen gas thrustersįalcon Heavy was designed and manufactured by SpaceX as a heavy-lift launch vehicle derived from the Falcon 9. Material: carbon fiber aluminum honeycomb
