To define the cycle parameters and calculate the performance of a real engine, numerous practical constraints need to be taken into account. These fall into two main categories: the limitations of available component technologies; and the operational considerations that are dependent on aircraft application. The main technology limiters are discussed. How they are incorporated into the cycle definition process is indicated. Operational factors include the extent of the intended flight envelope and the range of the critical flight conditions for which performance must be assured, and the balance to be struck between minimizing fuel consumption, maximizing installed power, and constraining costs of ownership. Taking these technology and operational influences into account, the basic cycle characteristics and approach to cycle choice are examined for three main classes of aircraft: subsonic transports, military combat aircraft, and helicopters.
