Q4// An aircraft is flying at a speed of 480 m/s. This aircraft used the simple aircraft air conditioning cycle and has 10 TR capacity plant as shown in figure 4 below. The cabin pressure is 1.01 bar and the cabin air temperature is maintained at 27 °C. The atmospheric temperature and pressure are 5 °C and 0.9 bar respectively. The pressure ratio of the compressor is 4.5. The temperature of air is reduced by 200 °C in the heat exchanger. The pressure drop in the heat exchanger is neglected The compressor, cooling turbine and ram efficiencies are 87%, 89% and 90% respectively.

27. In a gas turbine plant air at 10°C and 1.01 bar is compressed through a pressure ratio of 4 :1. In a heat exchanger and combustion chamber the air is heated to 700°C while its pressure drops 0.14 bar. After expansion through the turbine the air passes through a heat exchanger which cools the air through 75% of maximum range possible, while the pressure drops 0.14 bar, and the air is finally exhausted to atmosphere. The isentropic efficiency of the compressor is 0.80 and that of turbine 0.85. Calculate the efficiency of the plant. (Ans. 22.76%)
