Abstract

The invention provides a double-section flapping wing aircraft with deployable active folding wings, which comprises an aircraft body, two deployable active folding double-section wings symmetricallyarranged on two sides of the aircraft body and an empennage connected to the rear of the aircraft body, and the aircraft body comprises a frame and a transmission mechanism in transmission connectionwith the deployable active folding double-section wings; the transmission mechanism comprises a reduction gear set and two sets of double-shaking mechanisms in driving connection, the two sets of double-shaking mechanisms are symmetrically arranged on the left side and the right side of the central axis of the aircraft body, and the reduction gear set drives the two sets of double-shaking mechanisms to transmit power to flapping of the double-section wings. Flexible maneuverability and aerodynamic performance are both considered, and the overall performance of the double-section type wing aircraft is improved.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a two-stage flapping-wing aircraft capable of extending and actively folding wings. Background technique [0002] Since the 1990s, unmanned aerial vehicles (UAV, Unmanned Aerial Vehicle) have developed vigorously. On the one hand, UAVs have shown superior performance in long-term and large-scale continuous reconnaissance over theaters. UAVs play a unique role in reconnaissance and other aspects, and UAVs have become an important auxiliary for military operations. In the civilian field, UAVs are also widely used. At present, micro-aircraft have been used in traffic monitoring, which provides important support for traffic relief; in rescue and search and rescue, in some dangerous occasions, people cannot reach the scene. At this time, micro-aircraft Aircraft can play a huge role; applied to transportation, in today's e-commerce era, the express delivery industry is developing rapidly. At p...
