Propeller arrangement structure capable of achieving internally cooperative jet flow and controlling method

Abstract

The invention provides a propeller arrangement structure capable of achieving an internally cooperative jet flow and a controlling method. The arrangement structure is characterized in that blades are divided into a plurality of insulated single chambers which are arranged in a sectional-type continuous manner through a shell plate structure in the extension direction of the blades of a propeller. An individually cooperative jet flow apparatus is disposed in each insulated single chamber. Each cooperative jet flow apparatus comprises: a gas inlet, a gas outlet and at least one jet flow power apparatus, wherein the gas inlet is arranged on a back edge position of an upper stressed skin of the insulated single chamber in which the cooperative jet flow apparatus is arranged, and the gas outlet is arranged on a front edge position of an upper stressed skin of the insulated single chamber in which the cooperative jet flow apparatus is arranged. The jet flow apparatus is installed in an internal space of the insulated single chamber in which the cooperative jet flow apparatus is arranged.

Description

technical field [0001] The invention belongs to the technical field of flow control, and in particular relates to a propeller layout configuration and a control method capable of realizing internal coordinated jet flow. Background technique [0002] With the continuous development of aviation technology, material technology and other science and technology, high-altitude airships have broad application prospects in communication, remote sensing, early warning and other fields by virtue of the stable meteorological conditions in the stratosphere and good electromagnetic characteristics. . [0003] Compared with traditional aircraft propellers, high-altitude airship propellers work at altitudes where the atmospheric density is less than 10% of sea level, and due to their larger diameters, although the working state Reynolds number is low, the tip Mach number can reach more than 0.6. According to the working characteristics of the high-altitude airship propeller, although the ...

AI Technical Summary

Problems solved by technology

Traditional aircraft flow control methods include slats, flaps, vortex generators, boundary layer blowing and suction, etc., but it will bring unexpected parasitic resistance or complex moving parts, ventilation lines, engine thrust and efficiency loss and other problems

In recent years, the emerging flow control technologies, such as synthetic jets, plasma and other flow control technologies, can improve the above problems, but the current flow control technologies generally have the problem of low propeller working efficiency, which is difficult to meet high-performance high-altitude Airship Propeller Design Requirements
