This is role of the Brayton cycle with intercooling, reheating and regeneration. Air enters the compressor of an air-standard regenerative gas turbine at p 1 = 14.7 lbf/in.
Gas turbines are heat cycle engines. 2, T 1 = 530°R with a mass flow rate of 90,000 lb/h. The pressure ratio across the two-stage turbine is also 10. Ts diagram of Brayton cycle with reheat, intercooling and heat regeneration. 7: A gas-turbine engine with two-stage compression with intercooling, two-stage expansion with reheating, and regeneration. For a thrust engine this is ideal.
25 compressor (1AC) and a two-stage compressor with intercooling (1ABD). Brayton Cycle with Intercooling, Reheat & Regeneration A regenerative gas turbine with intercooling and reheat operates at steady state.

9-107C (c) The Carnot (or Ericsson) cycle efficiency. The back work ratio of a gas-turbine improves as a result of intercooling and reheating. Reheat, Intercooling and Regeneration in Brayton Cycle. When intercooling and reheating are used, regeneration becomes more attractive since a greater potential for regeneration exists. 9-106C Because the steady-flow work is proportional to the specific volume of the gas. Regeneration According to the working of the gas turbine the gasses for combustion are first get compresses in compressor and they move forwards for combustion. Regeneration, Reheat, and Compression with Intercooling. The pressure ratio across the two-stage compressor is 10. The reheat is performed by spraying additional fuel into the exhaust gases. Reheating increases the average specific volume of the gas, and thus the turbine work output. Intercooling decreases the average specific volume of the gas during compression, and thus the compressor work. Air enters the compressor at 100 kPa, 300 K with a mass flow rate of 5.807kg/s.

Most of the energy they produce goes back into the compressors, the rest goes out the tailpipe. This is possible since after the first combustion, the exhaust gases still contain enough Oxygen (remember that the mass ratio between air/fuel is > 50). As the number of compression and expansion stages increases, the gas-turbine cycle with intercooling, reheating, and regeneration approaches the Ericsson cycle. Internal combustion engines and gas turbines undergo gas power cycle. The two major application areas of gas-turbine engines are aircraft propulsion and electric power generation. The Brayton Cycle with Intercooling, Reheating and Regeneration Example An ideal gas-turbine cycle with two stages of compression and two stages of expansion has an overall pressure ratio of 8. Other articles where Reheat turbine is discussed: gas-turbine engine: Intercooling, reheating, and regeneration: …(2) increasing turbine output by reheating after partial expansion, or (3) decreasing fuel consumption by regeneration. This section will introduce the ideal cycle for gas-turbine engine - Brayton cycle with intercooling, reheating, and regeneration. Fig. Why? The compressor pressure ratio is 10, the turbine inlet temperature is 2200°R, and the regenerator effectiveness is 80%.

Intercooling and reheating always decreases the thermal efficiency unless they are accompanied by regeneration. Is reheating is necessary because gas after existing the high pressure stage will be at such a low pressure that it cannot be used in second stage of gas turbine.
