Problems solved by technology

The existing three-dimensional fabric technology cannot realize the integral weaving of the rudder shaft and rudder surface of the control rudder, and at the same time cannot meet the requirements that different parts of the control rudder have different load-carrying capacities. It is necessary to develop a new type of integral rudder reinforcement fabric

Abstract

The invention discloses an integrated rudder-enhancing textile and a knitting method thereof. The textile is a textile of a coupled structure and includes a rudder shaft area and a rudder face area, a rudder shaft area textile body is of a multi-directional interwoven structure, a rudder face area textile body is of a three-directional interwoven structure, the two structures are in seamless connection through a weft yarn system penetrating through the width direction and form the integrated textile. The multi-directional interwoven structure of the rudder shaft area textile body includes slant yarn which is spirally oriented around the central line of a rudder shaft, and the torsion resistance performance of the rudder shaft can be effectively improved. Meanwhile, the three-directional interwoven structure of the rudder face area textile body includes warp yarn and weft yarn which are straight oriented along a rudder plane, and the bending resistance performance of a rudder face is ensured. According to the knitting method of the integrated rudder-enhancing textile, on the basis of a current three-dimensional textile kitting method, through the multi-directional motion design of a spindle, the motion of the spindle is controlled flexibly, the knitting of the coupled structure is achieved, and the knitting method of the integrated rudder-enhancing textile is simple in process and high in maneuverability.

Description

technical field [0001] The invention relates to the field of three-dimensional fabric preparation, in particular to an integral rudder reinforcement fabric and a weaving method thereof. Background technique [0002] Hypersonic vehicles are a strategic development direction in the future aerospace field. In order to ensure that the aircraft has efficient penetration and precise guidance during hypersonic flight to achieve the purpose of ultra-long-range precision strikes, the new generation of aircraft generally adopts control rudder technology with high control efficiency for maneuvering orbit changes. The new generation of near-space vehicles fly at hypersonic speed in the atmosphere for a long time, the thermal load temperature is high, and the aerodynamic heating is serious, so it is necessary to use non-metallic control rudders with high temperature resistance (CN201610060069.2). [0003] The three-dimensional fabric is the reinforcing structural phase of the non-metall...
