Embodiment Construction

[0029] Such as figure 1 , figure 2 As shown, a mosaic-type laminate side spray nose cone includes a circular base 4, and the top surface of the circular base 4 is provided with a spherical cone-shaped sweating laminate stack. The sweating laminate stack is composed of multiple The circular sweating laminates 15 and 16 with increasing heights and decreasing radii are coaxially stacked; the center of the circular base 4 is provided with a base sweating main channel 8 that leads to the stacked body of spherical conical laminates for cooling. , and is provided with a fixed rod 5 passing through the main sweating channel 8 of the bottom platform and a stacked body of sweating laminates, such as Figure 9 As shown, the top of the fixed rod 5 is arc-shaped and the top of the fixed rod 5 is covered on the top of the laminated body of sweating; the fixed rod 5 is provided with a nozzle 12 leading to the cooling medium and a cooling medium inflow inlet 7 ; A side spray mechanism is i...

Abstract

The invention discloses a device for controlling active postures in postures of a high speed aircraft, particularly relates to an inlaid type laminate side-spraying nose cone which comprises a circular bottom table, wherein a ball-cone shaped sweating laminate superposed body is arranged on the top surface of the circular bottom table, a bottom table sweating main passage for leading cooling working medium into the sweating laminate superposed body and a fixing rod penetrating through the bottom table sweating main passage and the sweating laminate superposed body are arranged in the center of the circular bottom table; a side spraying mechanism is additionally arranged between the circular bottom table and the laminate superposed body, and a side spraying runner for spraying a side spraying working medium onto the outer side of the laminate superposed body is arranged in the side spraying mechanism; a side spraying passage for leading the side spraying working medium into the side spraying runner is arranged on the circular bottom table. Since the inlaid type laminate side-spraying nose cone is formed through spreading and superposition of laminates with etched the side-spraying runner, the requirements of control on the postures of the aircraft can be met, the effect of controlling on side spraying flow is also realized, and the inlaid type laminate side-spraying nose cone has a simple structure, is light in weight and has a strong space adaptability.

Description

technical field [0001] The invention relates to a device for active attitude control of a high-speed aircraft, in particular to a side spray nose cone of a mosaic type laminate. Background technique [0002] Lateral jet flow control is a kind of jet flow reaction control system (Reaction Control System), which is generated by using the side jet flow reaction force generated by the micro-engine installed on the aircraft and the interference between the jet flow and the incoming flow. It is a new type of control system that controls the trajectory of the aircraft by the interference force, and is one of the key technologies for precise strike and attitude adjustment. It has the characteristics of short reaction time, high control efficiency, little influence by environment and speed, and good stealth effect. [0003] Compared with traditional aerodynamic control surfaces, side jets have the following advantages: 1) aerodynamic surface control requires high dynamic pressure. W...
