Abstract

The invention provides a wing with changeable trailing edge camber driven by a shape memory spring, relating to a wing with a changeable trailing edge camber, and aiming at the problems of traditional airplanes that a mechanism is complex and heavy, airflow breakaway is quite early and aerodynamic efficiency is low. The front end face and the back end face of an upper metal plate are fixedly connected with the front end faces of a connecting plate and the trailing edge; the front end face and the back end face of the lower metal plate are fixedly connected with the front end face of the connecting plate and the trailing edge; the same side surface of the upper metal plate and the lower metal plate are fixed with an upper prop stay and a lower prop stay; the two ends of a first shape memory spring are fixedly connected with a fixed plate and the upper metal plate; the two ends of a second shape memory spring are fixedly connected with the front end faces of the upper prop stay and the trailing edge; the two ends of a third shape memory spring are fixedly connected with the fixed plate and the lower metal plate; and the two ends of a fourth shape memory spring are fixedly connected with the front end faces of the lower prop stay and the trailing edge. The invention has the advantages of light weight, simple structure and high aerodynamic efficiency.

Description

technical field [0001] The invention relates to a variable trailing edge camber wing. Background technique [0002] At present, the control surfaces (such as ailerons and flaps) of most aircraft use mechanical drive mechanisms to change the camber of the wings to provide the aircraft with the aerodynamic force required for maneuvering. However, the control surface using a mechanical drive mechanism has the problems of complex mechanism, heavy weight, premature separation of airflow, and low aerodynamic efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a variable trailing edge camber wing driven by a shape memory spring, which replaces the traditional mechanical drive mechanism, so as to solve the problems of complex and heavy control surface mechanism of the existing aircraft, premature airflow separation and low aerodynamic efficiency. question. [0004] The technical scheme that the present invention takes for solving the...
