WebQuestion 2 An aircraft engine operates on a simple ideal Brayton cycle with a pressure ratio of 10. Heat is added to the combustion chamber producing air at 1700 K. The air passes through the engine at a rate of 1 kg/s. The air at the beginning of the compression is at 70 kPa and 280 K. Using the variable specific heat approached, determine ... Engineers have studied the various heat-engine cycles to improve the amount of usable work they could extract from a given power source. The Carnot cycle limit cannot be reached with any gas-based cycle, but engineers have found at least two ways to bypass that limit and one way to get better efficiency without bending any rules: 1. Increase the temperature difference in the heat engine. The simplest way to do this is to incre…
