The engine configuration included 21 engines in an outer ring and 14 in an inner ring. The center cluster of seven engines would be able to gimbal for directional control. However, some directional control would be achieved via differential thrust with the fixed engines. Each engine could throttle to between 20 and 100 percent of rated thrust. [56]
The Merlin 1D engine. The first stage is powered by three Falcon 9 derived cores, each equipped with nine Merlin 1D engines. The Falcon Heavy has a total sea-level thrust at liftoff of 22.82 MN (5,130,000 lbf), from the 27 Merlin 1D engines, while thrust rises to 24.68 MN (5,550,000 lbf) as the craft climbs out of the atmosphere.

The Delta IV Heavy (Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It had the highest capacity of any operational launch vehicle in the world after the retirement of the Space Shuttle in 2011 until the Falcon Heavy debuted in 2018, and it was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024.
The various models in the PW1000G family can generate 15,000 to 33,000 pounds-force (67 to 147 kilonewtons) of thrust. The engine is used on the A220, A320neo family, Embraer E-Jet E2 and the Russian Yakovlev MC-21 (although exports were stopped as part of the international sanctions during the Russian invasion of Ukraine).

Aircraft engine performance refers to factors including thrust or shaft power for fuel consumed, weight, cost, outside dimensions and life. It includes meeting regulated environmental limits which apply to emissions of noise and chemical pollutants, and regulated safety aspects which require a design that can safely tolerate environmental hazards such as birds, rain, hail and icing conditions.
In 2011, performance goals for the engine were a vacuum thrust of 690 kN (155,000 lbf), a vacuum specific impulse (I sp) of 310 s (3.0 km/s), an expansion ratio of 16 (as opposed to the previous 14.5 of the Merlin 1C) and chamber pressure in the "sweet spot" of 9.7 MPa (1,410 psi). Merlin 1D was originally designed to throttle between 100% and ...
