Embodiment Construction

[0078] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0079] In this embodiment, the instantaneous energy efficiency optimization method based on multiple evaluation objectives is applied to the integrated thermal / energy system of the aircraft, such as figure 1 As shown, the comprehensive integrated heat / energy system is divided into two units, namely a semi-closed air refrigeration cycle unit and a combined power unit. In the figure, ISG is the integrated starter / generator, C is the compressor, CT is the cooling turbine, and PT is the power turbine. The combined power unit includes a compressor, an integrated starter / generator, a cooling turbine, a power turbine, and a dual-mode combustor, which provide power for the entire system and are the core components of the aircraft's integrated thermal / energy system. The semi-closed air cooling cycle unit draws air from the main engine or the outside atmosph...
