A Boot strap evaporative air refrigeration system is employed in an aero plane, moving with a Mach number of 1.5 to take 30 tonnes of refrigeration load of the cabin. The cooling air is taken from the main compressor at 5 bar and further compressed to 9 bar which is run by cooling turbine. The following data may be used: The ambient condition 0.52 bar,-13c , isentropic efficiencies of main compressor is 91% and secondary compressor is 82%. And turbine...

3. Consider a dual-loop cycle utilizing air as the working fluid is shown schematically in the figure below. Air enters the compressor at 1 bar and 4°C and is compressed to 3 bar. Part of the air exiting the compressor enters the refrigeration cycle and remaining enters the power cycle. The air supplied to the refrigeration cycle from the compressor is cooled to the 55°C at constant pressure in a heat exchanger and then expands in a turbine to 1...

Question2 a. Referring to the effect on the thermodynamic cycle, explain how bleeding of air to cool turbine blades leads to improvement in engine performance, despite the fact that such bleed air undergoes minimal momentum change and thus contributes negligible thrust. A turbojet engine flies at Mach 2, and 60,000ft, whe the airflow is bled from the high pressure end of the compressor, which has a pressure ratio of 8:1. This bleed air is used to cool the turbine blades...

2. An aircraft with a single turbojet engine (with an inlet area of 1 m2) is flying at cruising condition with a flight Mach number of 0.7. The ambient temperature and pressure are 250 K and 100 kPa, respectively. The engine compressor pressure ratio is 12, and the turbine inlet temperature is 1200 K. Assume all mechanical components are operating at isentropic condition and the specific heat can be considered a constant (throughout the entire engine) of 1 kJ/(kg K)....

.A-7 The gas turbine engines that are used on a military jet air plane likely consists of a diffuser, compressor, combustor, turbine, afterburmer, and nozzle that are arranged in series as shown in Figure 4.A-7(a) and flying with a velocity of 350 mph. The analysis will be carried out on a component-by component basis. Model the air as an ideal gas and assume that it has constant c and cp R 287.1 Ikg-K and c-1005...
