then with 70% afterburning under the same conditions of
flight,then with 70% afterburning under the same conditions of
flight, the consumption will be increased to approximately
2.53 lb./hr./lb. thrust. With an increase in height to 35,000
feet this latter figure of 2.53 lb./hr./lb. thrust will fall slightly
to about 2.34 lb./hr./lb. thrust due to the reduced intake
temperature. When this additional fuel consumption is
combined with the improved rate of takeoff and climb
(Figure 8e49), it is found that the amount of fuel required to
reduce the time taken to reach operation height is not
excessive.
