If an aircraft has maximum Mach number of 2 and bypass ratio of 0.71 then, what will be the weight of the engine? (Find the approximate value. Given thrust at takeoff is 10000 Unit.)

If an aircraft has maximum Mach number of 2 and bypass ratio of 0.71 then, what will be the weight of the engine? (Find the approximate value. Given thrust at takeoff is 10000 Unit.) Correct Answer 1058.5 unit

Given, Mach number M = 2, BPR = 0.71, Thrust T = 10000 unit Now, Weight is given by, W = 0.063*T1.1*M0.25*e -0.81*BPR W = 0.063*100001.1*20.25*e -0.81*0.71 W = 0.063*25118.86*1.189*0.5626 = 1058.5 unit
