重复使用贮箱是重复使用运载器的关键部件,使用寿命长,受力复杂,构型独特,是重复使用运载器研制的难点,为找到一种科学合理的研制方法,本文对重复使用液氧贮箱的设计、制造与试验进行研究.在传统火箭贮箱研制的基础上,进行了创新研究,阐述了设计思想、设计理念和贮箱材料选择,发明了液氧贮箱的前支撑、消能器与箱内附件的连接结构;对箱底的成型工艺和箱体的焊接方法进行研究得出:整体旋压成型工艺优于传统的瓜瓣拼焊工艺,真空电子束焊接可以保证箱体质量和尺寸精度;关于试验的创新包括用试片级前支撑结构选型试验和强度极限试验取代全尺寸真实环境试验,进行箱外消能器测试而不是箱内测试,以及将光纤检测技术纳入传统的箱体静力试验.
Design,Manufacturing,and Experimental Research on Reusable Liquid Oxygen Storage Tank
The reusable storage tank is a key component of reusable launch vehicles.Long service life,complex stress,and unique configuration are the difficulties in the development of reusable launch vehicles.In order to find a scientific and reasonable development method,the design,manufacturing,and testing of reusable liquid oxygen storage tanks are studied.On the basis of the development of traditional rocket storage tanks,innovative research is carried out,the design idea,design concept and material selection of the tanks is expounded.The front support of the liquid oxygen storage tank,the connection structure between the energy dissipator and the accessories inside the tank are invented.Research on the forming process of the bottom of the tank and the welding method of the tank has shown that the integral spinning forming process is superior to the traditional melon petal welding process,and vacuum electron beam welding can ensure the quality and dimensional accuracy of the box.Innovation in the experiment includes replacing full-scale real environment testing with specimen level front support structure selection testing and ultimate strength testing,conducting out of external energy dissipator testing instead of internal testing,and incorporating fiber optic detection technology into traditional static tank testing.
