Chinese Flight Test Establishment, Xi' an 710089, China

摘要

摘要: 受油装置作为受油机的重要机构与加油设备建立输油通道，与加油设备对接过程中的载荷大小对于受油装置结构强度设计具有重要意义。本文根据受油装置结构形式，提出基于应变电测原理的受油装置对接载荷测量方法。在空中加油吊舱地面调试试验期间搭建可移动式测试系统，验证对接载荷测量思路及方法，获取了锥套与受油插头对接过程中受油管上的应变数据，分析了对接过程中的载荷变化规律，并结合受油管几何模型估算给出了对接过程中的轴向载荷大小，为后续空中加油过程对接载荷测量进行了原理及可行性验证。

Abstract: Oil receiving device is an important mechanism of oil receiving machine and oil filling machine to establish oil transmission channel, its load magnitude during docking with refueling equipment is of great significance to structural strength design of refueling equipment. In this paper, according to the structure of oil receiving device, a method for measuring butt load of oil receiving device based on strain electrical measurement principle is proposed. A portable test system during ground debugging test of aerial refueling pod is built, and the idea and method of docking load measurement are verified. The strain data on the receiving pipe during the butting process between the cone sleeve and the receiving plug are obtained, the law of load variation in docking process is analyzed. Based on the geometric model of the receiving tubing, the axial load in the butting process is estimated, the principle and feasibility of docking load measurement for subsequent aerial refueling process are verified.
