Subsonic non after burning engine needs to be design based on following data. Take off trust is 15000 N and bypass ratio is 1.2. Find the weight of this engine. Consider first order statistical jet engine model. Correct Answer 3123 unit

Given, Thrust T = 15000N, BPR = 1.2 Now, weight is given by, W = 0.084 * (T1.1)* e (-0.045*BPR). W = 0.084 * (150001.1) * e (-0.045*1.2) = 0.084*39237.4147*0.9474 = 3123 unit.
