Abstract

The invention relates to an intelligent wing composite-material trailing edge system. A trailing edge sensing and control system is composed of a fiber grating sensor (18) and driving software. Two ends of a pneumatic muscle driver in the trailing edge driving mechanism are respectively installed and fixed at a front beam (11) and a rear beam (9) of a wing. A limiting column (7) is fixed on a composite substrate (3); a steel cable (6) passes through the hole of the limiting column (7) and then two ends are connected with the pneumatic muscle driver (13) and a trailing edge strip (4) respectively. A control computer (15) is connected with the pneumatic muscle driver (13) through an electromagnetic proportional valve (21) to drive the deformation of the trailing edge structure. According tothe invention, the aerodynamic efficiency of the wing structure can be improved; and the noise generated by the aerodynamics of the wing can be reduced. The bending of the wing can be changed based onrequirements of the flight states to realize intelligent sensing and control of the wing. Therefore, the important practical foundation is laid for engineering verification of the flexible variable-bending wing trailing edge.

Description

Technical field [0001] The invention belongs to variant aircraft structure or intelligent aircraft structure technology, and relates to an intelligent wing composite material trailing edge system. Background technique [0002] In recent years, with the requirements of green aviation technology for civil aircraft energy reduction and aircraft noise reduction, as well as the rapid development of materials and structural technology, the active surface of the trailing edge of the aircraft wing has gradually developed from the traditional rigid structure to the main engine The flexible structure in which the wings are seamlessly connected and deformable and load-bearing is called the variable camber trailing edge structure. If this variable camber trailing edge structure also has sensing and control functions, it is called an intelligent trailing edge structure, an intelligent variable camber trailing edge structure or an intelligent wing variable camber trailing edge structure. The ...
