  • B-52 Performance Questions

    From peterwezeman@hotmail.com@21:1/5 to All on Tue Aug 10 15:27:56 2021
    For a Boeing B-52H, on a mission at maximum takeoff weight, what
    would be the initial cruising altitude and true airspeed? How much
    fuel would have been burned off in takeoff and climb?

    My thanks in advance for all replies.

    OK - From the June 1969 B-52H Standard Aircraft Characteristics:'
    Standard Day - 59 deg F/ 15 C, QNH 29.29" / 1003 mb
    Max Takeoff Weight 488,000 lbs
    Takeoff Ground RUn 7,420 ft (TO Power)
    Takeoff Run to clear 50' 9,580 (TO Power)
    Initial Cruising Alt: 31,950 ft
    Average Cruise Sped (TAS) 453 Kts

    Fuel Burn on the ground is about 150 lbs/minute
    Fuel Burn for takeoff to climb sped is about 3,500 lbs
    Fuel burn for climbout is about 12,500 lbs

    My friend who was a B-52 tailgunner, last
    night told me, that generally in their
    flightplan, early on they would descend
    to about 27,000 feet to refuel
    (to make up for what lost in the climb.)
