Embodiment Construction

[0041] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0042] The energy management strategy of the aircraft adaptive power and thermal management system (APTMS) that the present invention relates to, the APTMS mainly includes a semi-closed air refrigeration cycle unit and a combined power unit, such as figure 1 shown. 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 refrigeration turbine, a power turbine, and a dual-mode combustor to provide power for the entire system and is the core component of APTMS. The semi-closed air cooling cycle unit draws air from the main engine or the outside atmosphere, uses air and fuel as heat sinks, and provides cooling for the cockpit and avionics equipment through a variety of heat exchangers. The first...

Abstract

The invention discloses an energy management strategy for an airplane adaptive power and thermal management system (APTMS), and belongs to the technical field of airplane integrated heat/energy. According to the invention, firstly, an APTMS energy optimization rule is obtained through off-line simulation by means of an instantaneous optimization energy management strategy and by combining a plurality of working conditions, then energy management rules are classified by means of fuzzy C-means clustering, and a part of the rules are extracted to serve as training samples of a nerve network. A BP nerve network controller obtained through training controls energy distribution of the system in dependence on the real-time working condition of the APTMS in order to achieve energy optimization management. The energy management strategy for the airplane adaptive power and thermal management system (APTMS) can guarantee fuel economy of the APTMS, and the energy management real-time performance is obviously improved.

Description

Technical field: [0001] The invention discloses an energy management strategy of an aircraft adaptive power and thermal management system based on instantaneous energy optimization and BP neural network, and belongs to the technical field of aircraft comprehensive integration heat / energy. Background technique: [0002] In order to meet the development needs of energy-optimized aircraft in the future, the multi-electric and integrated technology of airborne systems has become the focus of current research. The new adaptive power and thermal management system (APTMS) is regarded as an important development direction of integrated thermal / energy management technology for airborne systems. It integrates the functions of the emergency power system, auxiliary power system and environmental control system in the traditional airborne electromechanical system, adopts an adaptive combined power unit, and realizes the cross-linking and optimal management of multi-energy forms in the sy...
