Question 3. a) Write the thrust equation and explain the meaning of the symbols used in the thrust equation. (10p) b) The F-4 aircraft with two jet engines accelerates at take-off. The exhaust exit speed according to the aircraft and the mass flow in the engine are considered constant. How does the thrust change when the plane accelerates? Show it in thrust-speed diagram. (10p) c) The outlet pressure of a jet engine decreases with respect to atmospheric pressure. How does thrust change if mass flow, input and output speeds are assumed to remain constant? Show it in thrust-outlet pressure. (10p) Question 3. a) Write the thrust equation and explain the meaning of the symbols used in the thrust equation.
