Description

Technical Field

[0001] The present invention relates to the technical field of wind tunnel design research, and more specifically, to an airway design for an entertainment wind tunnel. Background Art

[0002] The entertainment wind tunnel combines the principles of aerodynamics and entertainment project design, and uses a high-power fan to generate a stable high-speed airflow (usually 40 - 60 m / s), "blowing" the experiencer into the air to suspend, simulating the free fall of skydiving or the sense of weightlessness in space;

[0003] Currently, the existing entertainment wind tunnels adopt a fixed vertical wind tunnel structure, which has relatively high load-bearing requirements for the bottom of the wind tunnel, high construction and operation costs, large energy consumption, high investment costs, and is not conducive to more comprehensive promotion and application; the existing entertainment wind tunnels are single, and can only be used indoors or outdoors, and their practicability needs to be improved.

[0004] Therefore, how to provide an airway design for an entertainment wind tunnel that can save energy, reduce operation costs, has stronger practicability, and combines education and entertainment is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0008] A base, in which a Q-shaped main push air duct and a Q-shaped boost air duct are provided. The Q-shaped boost air duct is communicated with the Q-shaped main push air duct. One ends of the Q-shaped boost air duct and the Q-shaped main push air duct that are far away from each other are both set as air power supply ends. A medium-speed fan and a high-speed fan are successively arranged at the air power supply end of the Q-shaped main push air duct, and a medium-speed fan and a high-speed fan are also successively arranged at the air power supply end of the Q-shaped boost air duct;

[0009] A central wind tunnel indoor flight airway, which is arranged at the central position of the base, is arranged at the intersection position of the Q-shaped main push air duct and the Q-shaped boost air duct, and the central wind tunnel indoor flight airway is communicated with the Q-shaped main push air duct and the Q-shaped boost air duct;

[0010] The large-circulation return air duct and the half-course small-circulation return air duct are both arranged on the base.

[0011] Furthermore, three Q-shaped boost air ducts are provided, and the airflows of the three Q-shaped boost air ducts converge with the airflow of the Q-shaped main push air duct at one point.

[0012] Furthermore, the inner diameter of the Q-shaped main push air duct is larger than that of the Q-shaped boost air duct. Jet pipes are provided on both the Q-shaped main push air duct and the three Q-shaped boost air ducts. The jet pipes are located between the medium-speed fan and the high-speed fan. N jet pipes are symmetrically arranged on both the Q-shaped main push air duct and the Q-shaped boost air duct, where N≥2.

[0013] Furthermore, three half-course small-circulation return air ducts are provided corresponding to the Q-shaped boost air ducts.

[0017] Through the above technical solutions, compared with the prior art, the present invention discloses an entertainment wind tunnel air duct design.

The airflow in the O-shaped circulation is smooth, with less energy loss, small wind resistance and low noise.
