Embodiment 1

[0050] Such as Figure 1-9b , a structure for strengthening vortex surfing according to the present invention, including a jet device, the jet device includes a nozzle hole 103, the nozzle hole 103 is arranged on the wingtip 11, and the jet device can open and close the nozzle hole 103, the nozzle hole 103 is used for spraying airflow.

[0051] The wing tip 11 refers to the winglet at the wing tip of the aircraft's wing. The jet device can be an existing jet, such as a small jet engine, etc., which can provide jet airflow to the nozzle hole 103 on the wingtip 11 . The number and size of the nozzle holes 103 are all determined according to actual conditions. Adopting the structure of strengthening vortex surfing described in this embodiment, by setting the nozzle hole 103 of the jet device on the wingtip 11, and opening and closing the nozzle hole 103 on the wing tip 11 through the jet device, the jet on the wingtip 11 can be actively controlled. The nozzle hole 103 sprays t...

Embodiment 2

[0068] This embodiment provides a wing for enhanced vortex surfing, which includes a wing body 1 , the wing body 1 includes a wingtip 11 , and the structure for enhancing vortex surfing described in Embodiment 1.

[0069] Adopt the wing that strengthens the vortex surfing described in this embodiment, be used on the aircraft, be arranged on the wingtip 11 of the described strengthened vortex surfing wing of the aircraft by the spray hole 103 of the jet device, and be active by the jet device Control the jet airflow of the nozzle hole 103 on the wingtip 11 to actively control the vortex ring volume of the front aircraft, thereby increasing the additional lift to the rear aircraft and reducing the fuel consumption of the rear aircraft, so as to reduce the overall fuel consumption of the formation aircraft.

Embodiment 3

[0071] This embodiment provides an aircraft with enhanced vortex surfing, including the wing with enhanced vortex surfing described in Embodiment 2. Generally, the wings for strengthening vortex surfing described in Embodiment 2 are arranged in pairs on the aircraft.

[0072]The aircraft adopting the enhanced vortex surfing of the present invention, by setting the nozzle hole 103 of the jet device on the wingtip 11 of the wing of the aircraft, and actively controlling the jet flow from the nozzle hole 103 on the wing tip 11 through the jet device, To actively control the vortex ring volume of the front aircraft, thereby increasing the additional lift to the rear aircraft and reducing the fuel consumption of the rear aircraft, so as to reduce the overall fuel consumption of the formation aircraft.

Abstract

The invention relates to the field of flight, in particular to a structure for enhancing vortex surfing, a wing and an aircraft. The structure for enhancing vortex surfing comprises a jet device, the jet device comprises spraying holes, each spraying hole is formed in a wingtip, the jet device can open and close the spraying holes, and the spraying holes are used for spraying airflow. According to the structure for enhancing vortex surfing, the spraying holes of the jet device are formed in the wingtip, the spraying holes located in the wingtips are actively controlled through the jet devices to jet airflow, the vortex circular rector of the front aircraft is actively controlled, then the additional lift force of the rear aircraft is increased, the oil consumption of the rear aircraft is reduced, and therefore the overall oil consumption of the formation aircraft is reduced.

Description

technical field [0001] The invention relates to the technical field of flying equipment, in particular to a structure for strengthening vortex surfing, a wing and an aircraft. Background technique [0002] Wing tip vortex is a major hazard to air traffic. When an aircraft encounters a front wing tip vortex while navigating in the air, it will cause violent flipping or sudden drop, especially during take-off and landing, and the impact is more serious. However, reasonable use of the wingtip vortex can provide additional lift for the rear aircraft. Therefore, a large number of theoretical studies have been carried out based on eddy current surfing technology, and it is considered to introduce the principle and technology of eddy current surfing into the field of civil aviation. [0003] The generation of wingtip vortex is because: the pressure on the lower surface of the wing is greater than the pressure on the upper surface of the wing, which generates lift, and at the same ...
