  • Falcon Heavy: 53 mT!! (update: F9 Blk II, Merlin 1D)

    Ho-ly-crap!! The biggest, baddest operatiinal launcher since Saturn V.

    53 metric tons to orbit vs the original 32 metric tons! This is 2x the cargo capability of the Space Shuttle and qualifies it as a Super-Heavy launch vehicle. Musk said FH should lower the launch cost of cargo to about $1,000/pound, about 10% of the cost/pound of the Shuttle.

    That's due to a new version of Merlin-1.

    3.8 million lb/ft of thrust, equal to 15 full-throttle 747's.

    2 launch manned lunar missions, 4 launch manned Mars missions possible.

    Jeeezzzz....

    Falcon Heavy’s first stage will be made up of three nine-engine cores, which are used as the first stage of the SpaceX Falcon 9 launch vehicle. It will be powered by SpaceX’s upgraded Merlin engines currently being tested at the SpaceX rocket development facility in McGregor, Texas. SpaceX has already designed the Falcon 9 first stage to support the additional loads of this configuration, and with common structures and engines for both Falcon 9 and Falcon Heavy, development and operation of the Falcon Heavy will be highly cost-effective.

    FALCON HEAVY

    Mass to LEO (200 km, 28.5 deg): 53,000 kg (117,000 lb)
    Overall Length: 69.2 m (227 ft)
    Width (body): 3.6 m (12 ft) x 11.6 m (38 ft)
    Width (fairing): 5.2 m (17 ft)
    Mass on liftoff: 1,400,000 kg (3,100,000 lb)
    Thrust on liftoff: 17 MN (3,800,000 lbf)

    From another release -
    Falcon Heavy will be the first rocket in history to do propellant cross-feed from the side boosters to the center core, thus leaving the center core with most of its propellant after the side boosters separate. The net effect is that Falcon Heavy achieves performance comparable to a three stage rocket, even though only the upper stage is airlit, further improving both payload performance and reliability. Crossfeed is not required for missions below 100,000 lbs, and can be turned off if desired.

    More interesting info from a SpaceNews tweet: "SpaceX says its exploring a 150MT to orbit Falcon "super heavy" under a small NASA contract."

    This would be much larger than the 118MT Saturn V moon rocket.

    2 ways to do this -

    1) quick: a 5-core first stage - a central core with 4 strap-on boosters instead of FH's 2. That would ba a sight

    2) Falcon XX, a nearly 400 ft. monster which would require the 1.7 million lb-f Merlin 2 engine & more lead time.

      New comparidon pix showing in order L to R -

      (MT = metric ton = 2,200 lbs)
      (low orbit = 300 km/200 mi @28.5° inclination)

      Falcon 9 (Block I) w/cargo fairing: 10.4 MT to low orbit (current)
      Falcon 9 (Block II - aka Stretch) w/cargo fairing: 15 MT to low orbit
      Falcon Heavy w/cargo fairing: 53 MT to low orbit (could go higher)

      F9 Blk II/FH height: 69.2 m/227 ft
      Standard cargo fairing: 5.2 x 13.9 m (custom by order)

      F9 Block I used the 95k lb-ft Merlin 1C engine
      F9 Block II & Falcon Heavy will use the 140k lb-ft Merlin 1D engine

      Merlin 1D uses far fewer parts, a new SpaceX designed turbopump that can digest small metal debris and continue running, and it's designed to be built using mass-production techniques, many from the auto industry. LiPo batteries built by Tesla.

      Merlin 1D is undergoing qualification tests in Texas now. When it goes into production more Merlin 1D's will be produced than the rest of the worlds collective rocket engine output. Max production will be nearly double that.
