Shape memory polymer pipeline and use of shape memory polymer pipeline as aircraft engine intake

Abstract

The invention relates to a shape memory polymer pipeline and use of the shape memory polymer pipeline as an aircraft engine intake, in particular to a shape memory polymer pipeline and use thereof, which solve the problem that a structure of the conventional aircraft engine intake cannot be deformed according to requirements, so air inflow cannot be regulated and the shape of the air intake cannot be changed to cause that the through capacity of the aircraft engine intake is discordant with the requirement of an engine to influence the aerodynamics performance of an air engine. The shape memory polymer pipeline is made of a shape memory composition material, and the shape memory composition material consists of 5 to 98 volume parts of shape memory polymer materials, 2 to 95 volume parts of reinforcement phase materials and 0 to 100 volume parts of resistance heating materials; and the shape memory polymer pipeline serving as the aircraft engine intake overcomes the defect that the structure of the conventional air intake cannot be deformed according to the requirements, and regulates the air inflow and changes the shape of the air intake, so that the through capacity of the air intake is in accordance with the requirement of the engine to improve the aerodynamics performance of aircrafts.

Description

technical field [0001] The invention relates to a shape memory polymer pipe and its application. Background technique [0002] Shape memory polymers have received more and more attention because they can be used in medicine, aerospace, intelligent control and other fields. Shape memory polymer materials can actively produce large recovery deformations up to 100% under certain conditions, so they show great application potential in the field of intelligent active deformation structure research. Shape memory polymers can be divided into thermotropic, electrotropic, phototropic and solution-driven types according to different excitation forms. Among them, thermotropic shape memory polymer has the advantages of simple excitation form, large recoverable deformation and fast response speed, and is the most widely and deeply researched. Thermal-mechanical deformation process of thermally induced shape memory polymers: Above the glass transition temperature (Glass Transition Tempe...

Problems solved by technology

[0008] The purpose of the present invention is to provide a shape-memory polymer pipe and its application as an aircraft engine inlet, so as to solve the problem that the existing aircraft engine inlet structure cannot be deformed according to requirements, and then the air intake cannot be adjusted and changed. The shape of the intake port causes the inconsistency between the passage capacity of the air intake port of the aircraft engine and the requirements of the engine, which affects the aerodynamic performance of the aircraft engine
