Downwind airship

Abstract

A downwind airship is composed of a main air bag, a pod, an empennage, a power direction wing, a rotating disc and a wind direction controller. The airship is additionally provided with a direction caudal vertebra power sleeve, the rotating disc and the wind direction controller besides the conventional empennage. The wind direction controller can control the empennage and the caudal vertebra power sleeve to keep the downwind direction; the turntable can control the pod to fly to the target direction, and the pod can fly laterally and transversely or even reversely; a lifting power sleeve and a propelling power sleeve are independently mounted in the pod, so that lifting independent control can be realized, hovering can be realized more easily, and even a hovering function controlled by an automatic driving system of the airship can be realized, which cannot be realized by the turning-culvert airship; the airship is characterized in that the airship can be switched to a downwind control system so that the airship can fly or hover in a downwind state, the airship can be switched to a conventional control airship, and due to the fact that a huge airship body can keep the downwind state, the airship has higher wind resistance, flight attitudes such as hovering, upside-down flight and side flight can be achieved more easily, and the airship can be widely applied to the field of airships. And the airship control is more flexible.

Description

Technical Field

[0001] It belongs to the field of aerostats, specifically aircraft and airships. Background Art

[0002] At present, conventional airships all have a pod fixed below the main airbag's buoyant center of gravity. A pair of rotor culvert power thrust devices are generally installed on the left and right sides of the pod. When flying, the airship generally faces the flight direction or is tilted at a certain angle toward the flight direction due to the influence of the wind. If the flight direction deviates from the wind direction, the airship will be affected by a larger crosswind, making it difficult to fly, with reduced wind resistance and a sharp increase in power or fuel consumption. To control the airship to hover, whether it is remote control or human control, the rotor culvert needs to be controlled to a suitable inclination angle to generate a suitable forward and upward thrust and manually adjusted to the downwind direction to achieve hovering. Therefore, it is even more difficult to achieve hovering using a flight control system, as the flight control system cannot determine at what angle the rotor culvert can achieve hovering. Summary of the invention

In the downwind state, the airship is controlled to hover or move backward through the tail vertebrae power, and the airship can be controlled to move horizontally or sideways through the turntable. The advantage of the present invention is that the lift power sleeve and the propulsion power sleeve are independent, which is more convenient to realize the flight control control forward, hovering and other functions.
