Four-rotor-wing indoor airship

Abstract

The invention relates to a four-rotor-wing indoor airship, which is designed by solving the technical problems of poor stability and flight control system complexity caused by the adoption of vector driving movement and posture height coupling of the existing indoor airship and particularly solving the technical problems of insufficient lifting force, static instability, poor safety, high noise, high cost and the like of an indoor special-shaped airship. The four-rotor-wing indoor airship comprises an airship capsule, four rotor wing assemblies and a hanging cabin, wherein the rotor wing assemblies are symmetrically distributed on the airship capsule, each rotor wing assembly comprises a rotor wing support arm, a rotor wing motor, a protecting ring and a propeller, the inner end of the rotor wing support arm is fixedly connected onto the airship capsule, the rotor wing motor is fixedly arranged at the outer side of the rotor wing support arm, the propeller is arranged on a rotating shaft of the rotor wing motor and is driven by the rotor wing motor, and the protecting ring surrounds the propeller and is fixedly arranged on the rotor wing motor. The four-rotor-wing indoor airship has the advantages that the structure is simple, the stability and the operability are high, the possibility for cooperatively completing various activities with people is provided, and because the stability enhancement control and flight principle similar to that of a four-rotor-wing helicopter is adopted, the four-rotor-wing indoor airship has the characteristic of adaptability to the insufficient lifting force and the static instability of a special-shaped airship structure. The four-rotor-wing indoor airship has the characteristics that the energy is saved, safety and reliability are realized, no pollution is caused, the noise is low, and the like, and the wide application of the indoor airship can be promoted.

Description

Technical field: [0001] The invention relates to an indoor airship, in particular to a hull structure of a four-rotor indoor airship. It belongs to the field of indoor airship design and manufacture. Background technique: [0002] Indoor airship is a kind of aerostat with propulsion device, using the principle of buoyancy to lift into the air and controllable flight. The general length is 1-3m, and the width is 0.6-2m. In order to enhance the application effect, heterosexual shapes are generally used, such as dinosaurs, whales, tables and chairs, etc. Because of their smaller volume and lighter weight than outdoor airships, small ones can be mounted DV, or carry special loads such as: flowers, rings, etc. according to customer needs. In addition, the airship part of the indoor airship is mostly made of polyethylene or polyurethane materials, filled with helium, and the colors are varied. The shape generally adopts novel and heterosexual shapes. , such as: dolphins, sharks,...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the complicated flight control system and poor stability of existing indoor airships due to the high coupling of motion and attitude driven by vectors, especially for indoor heterosexual airships with insufficient lift and static instability, poor safety, high noise, and low cost. designed for advanced technical issues

The four-rotor symmetrical layout mode has the ability to automatically adapt to the design of most airships with special-shaped shapes. The static instability problem caused by the special-shaped shape is solved through the stability-enhancing controller, and the lift caused by the special-shaped shape is compensated by the lift of the four-rotor.
