Flapping aircraft scheme

Abstract

The invention relates to an aircraft in a fluid medium, in particular to a flapping aircraft scheme. In the field, breakthrough is achieved in minitype ornithopters, however, except minitype ornithopters, efficient manned flight can not be achieved so far due to the demanding requirement for materials. To overcome the demanding requirements of traditional flapping aircrafts for materials and make man-made flapping aircrafts have the flight function like insects, the invention provides a scheme according to which most rigid materials can be replaced with flexible materials. In the scheme, a flapping aircraft is composed of a pedal, a flapping wing and connecting ropes (or pull rods), wherein the flapping wing is composed of a wing rod and a wing membrane, and the wing membrane is attached to the wing rod. Through mechanism simplification, multi-point connection between the flapping wing and the pedal is achieved, and the flapping aircraft is stressed uniformly. Due to the fact that most rigid materials can be replaced with flexible materials, the requirement of the flapping aircraft for material rigidness is reduced greatly, and even the wing rod can be omitted so that popularization of manned flapping aircrafts can be achieved.

Description

Technical field [0001] The invention relates to an aircraft in a fluid medium, in particular to a proposal for an aircraft with flapping wings. Background technique [0002] At present, in order to realize high-efficiency flight (such as the flight of dragonflies), the existing field of flapping machines is pursuing high-efficiency flight of flapping wings. Strict requirements have made it impossible to achieve efficient manned flight so far. The manned wing flapping machine is still in the stage of model making and conception, and cannot be really put into practical use. Contents of the invention [0003] In order to get rid of the extremely stringent material requirements of the flapping aircraft in the past, and make the artificial wing flapping aircraft have the energy efficiency approaching that of insects, the present invention provides an alternative to flexible materials that can be used for most rigid materials, so that human beings can use the flapping aircraft ...
