The Dornier is a light freighter and feeder liner aircraft powered by two Lycoming IGSO-540-A1A six-cylinder horizontally opposed engines, each rated at 260 kW. Assume that Otto cycle represent the cycle for such a spark-ignition engine. Data for the engine is as follows: 1. Compression ratio: 8 2. Temperature and pressure at the beginning of the compression stroke: 300 K and 96 kPa 3. Rate of heat transfer during the constant volume stroke: 760 kJ/kg 4. Specific heat at constant volume: 0.72 kJ/ (kg·K) Shaft Engines 549 Calculate a. The pressure and temperature at the end of the heat addition process b. Network output c. Air mass flow rate d. Mean effective pressure
