The application relates to a waveguide coplanar slow wave line, belonging to the technical field of frequency scanning antennas, and solves the problem of large space occupation caused by independent design of the slow wave line and the radiation unit of the frequency scanning antenna in the prior art. The waveguide coplanar slow wave line is integrated with a rectangular waveguide; the slow wave line has multiple omega-shaped bends. One radiation unit is arranged on the slow wave line every interval of the omega-shaped bends. The application realizes the longest length of the slow wave line under the premise of fixed spacing of the radiation units, and realizes low profile design by arranging the slow wave line and the waveguide to be coplanar.

This invention proposes a full-size hybrid laminar flow vertical tail prototype structure for low-speed wind tunnels, belonging to the technical field of special test model design for low-speed wind tunnels. The aim is to achieve a lightweight and low-cost design for the full-size hybrid laminar flow vertical tail body while ensuring stability and maneuverability. In this invention, the upper, middle, and lower sections of the vertical tail are connected sequentially. The external body of the vertical tail is covered by a vertical tail skin and a cover plate. Heating wires are laid inside the vertical tail skin on one side of the middle section. Several pressure measurement holes are arranged on the upper and lower sections of the vertical tail. An air intake chamber is installed on the middle section of the vertical tail, comprising 21 independent air intake chambers. Each independent air intake chamber has four air intake holes and one independent air intake chamber pressure measurement hole on its sidewall. Steel pipes from the upper, middle, and lower sections of the vertical tail pass through reinforcing ribs to form a grid structure, with positioning rulers on both sides of the grid. This invention achieves a lightweight and low-cost design for the vertical tail, facilitating model installation in the wind tunnel and alleviating pressure on the support system.

The invention relates to the technical field of air conditioners, in particular to an air guide mechanism and an air conditioner, the air guide mechanism comprises a mounting support and an air guide plate, the mounting support is used for being connected with an air outlet of the air conditioner, and an air guide opening is formed in the mounting support; the air guide plate is rotationally arranged on the mounting bracket so as to shield or expose the air guide port; wherein the air deflector is provided with a connecting part, and the mounting bracket is provided with a first matching part and a second matching part; the air guide mechanism has a first assembly state and a second assembly state; in the first assembling state, the connecting part is rotationally matched with the first matching part, so that the air guide plate rotates within a first angle range; and in the second assembling state, the connecting part is rotationally matched with the second matching part, so that the air guide plate rotates within the second angle range. Through the design of the double assembly states, the technical defect that the air supply direction and angle of a traditional air guide structure are fixed and cannot be adjusted is effectively overcome, and the air guide plate can be rotationally adjusted within two different angle ranges through selective matching of the connecting part and the different matching parts.
