(4) Continuous Combustion. As discussed above, the fourstroke/cycle
pistontype engine performs four separate discrete events. Each event must be
consists of four events that are essentially the same as the pistontype
reciprocating engine; however, these events combine to form a continuous cycle.
As the gas turbine operates, each of the four events transpires continuously.
burn, expand, and maintain turbine speed, the cycle is said to be continuous
(5) Thermal Comparison. The pistontype engine operates at relatively
degrees Celsius) for a short duration of time. The hot components are cooled
rapidly to maintain relatively low temperatures of only a few hundred degrees.
limits it to approximately 1000 to 2000 degrees Fahrenheit (537.7 to 1090.3
degrees Celsius). This is done to retain the resilience of internal components
and inhibit formation of foreign matter on rotating parts.
furnish a uniform and steady airflow to the face of the compressor. Inlet
sections may be equipped with or without inlet guide vanes. Inlet guide vanes
serve to direct the air into the first stage of the compressor.
