Question 3 For a turbofan engine write down the mathematical expressions for 1. The thrust force 2. The overall efficiency Prove that the maximum overall efficiency is given by $\eta_{o,max} = \frac{(1 + \beta)u^2}{fQR}$ Question 4 Figure 2 illustrates a turbofan engine during testing in a test cell. It has the following characteristics: 1. $\beta = 3$, $f = 2\%$, $V_2 = 3V_1$ 2. $\dot{m}_a = 200kg/s$, thrust = 60kN. a) Calculate: $m_1$, $m_2$ and $m_r$. b) Evaluate $V_1$, $V_2$ if f is neglected. c) Calculate the propulsive efficiency.
