A remotely controlled model aircraft is powered by a miniature jet engine, comprising of a single-stage compressor, a combustion chamber, and a single-stage turbine. The jet engine
overall cycle pressure ratio rp = 4. It is started up in still air at ambient temperature T1 = 300 K,
ambient pressure p1 = 100 kPa, specific heat ratio k = 1.4. Make cold-air-standard
assumptions and determine the compressor exit pressure p2, the turbine entry pressure p3, and the compressor exit
temperature T2
