Dave - In reference to your doubts about a blown fuel drag engine realy
putting out the claimed hp do you agree with these numbers - Distance fallen
in 4.42 seconds at 1 G is 1/2 A (16) X seconds squared (4.42 X 4.42) = 312.58'
- Average acceleration for 1320' in 4.42 seconds is 1320'/312.58' = 4.22 G's -
The accelerating force for a 1900# object at 4.22 G's is 8018# - If the engine
is running for the entire time the equivalent of 332 mph (472.27 ft/sec) the
hp is ft lb (472.27 ft X 8018 lb) per second (1) /550 = 6884.84 hp - The true
hp would be reduced some because the engine runs less than the equivalent of
332 mph earlier in the run - Because the 6884.48 hp doesn't include the aero
drag (plenty) 6000 to 7000 hp can't be far off - John
