Embodiment Construction

[0030] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. For the sake of clarity, various parts in the drawings have not been drawn to scale. Also, some well-known parts may not be shown. There are many specific details of the invention described below, but the invention may be practiced without these specific details, as will be understood by those skilled in the art.

[0031] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean being directly on another layer or another region, or Other layers or regions are also included between it and another layer or another region. And, if the part is turned over, the layer, one region, will be "below" or "beneath" the other layer, another region.

Abstract

Disclosed an aerial vehicle . The aerial vehicle includes: a first ducted fan; and a plurality of second ducted fans which are distributed at equal intervals around the first ducted fan; the first ducted fan and the second ducted fans include a duct and a propeller; the propellers rotate in the ducts to provide power, wherein one end of the longitudinal section of each duct is smooth, while the other end is tipped. The second ducted fans according to the aerial vehicle are distributed at intervals around the first ducted fan; the aerial vehicle flight or hovering is more stable. The duct longitudinal section of the first ducted fan and the second ducted fans has one smooth and the other tipped end tipped, so that form resistance can occur to the introduction of aerial vehicles in the ducted fans is reduced at the other end, and pneumatic performance of the aerial vehicle is optimized.

Description

technical field [0001] The present invention relates to the field of aircraft, and more specifically, relates to an aircraft. Background technique [0002] Multi-rotor aircraft has the advantages of flexible maneuverability, fast response, unmanned driving, and precise control. It is widely used in many neighborhoods, such as performing image shooting tasks and detection tasks. [0003] The multi-rotor flight of the prior art mostly uses open propellers. When the blades of the propellers move in a high-speed circular motion, the speed at the blade tip is the highest, the induced resistance is relatively large, and the impact on the external airflow causes large noise, resulting in low aerodynamic efficiency. [0004] An improvement in the prior art is to use ducted fan propellers instead of open propellers. The ducted fan refers to the propeller system in which ducts are arranged around the open propellers. Under the protection of the ducts, the ducted fan aircraft has high...
