摘要:
本文主要介绍分析了美国卡尔斯潘公司的系列高超声速脉冲设备建设历程。为了适应不同的研究目的,卡尔斯潘公司先后建造了6座激波风洞和2座膨胀管风洞等脉冲设备,它们分别为11×15英寸激波风洞、48英寸激波风洞、96英寸激波风洞、无名高焓激波风洞、LENS Ⅰ激波风洞、LENS Ⅱ激波风洞、LENS X膨胀管风洞以及LENS XX膨胀管风洞。不管是设备规模,还是试验模拟能力以及测试技术水平,这些脉冲设备基本上代表了同期世界最高水平,并在一定时间内依然处于世界领先地位。本文通过对卡尔斯潘公司的LENS系列脉冲设备建设历程进行分析,希望可以对我国脉冲设备建设和发展相应的测试技术等提供一些有益的借鉴和参考。
Abstract:
This paper describes and analyses the serial hypersonic impulse facility building course of Calspan Corporation in USA.To meet the needs of different research,Calspan corpora-tion has built six shock tunnels and two expansion tunnels successively which include 1 1 ×1 5 inch shock tunnel,48 inch shock tunnel,96 inch shock tunnel,high enthalpy shock tunnel,LENS I shock tunnel,LENS II shock tunnel,LENS X expansion tunnel and LENS XX expansion tunnel. The dimension,simulation capability and testing technique all represent the tiptop level in the corresponding period.The analysis of LENS series impulse facility building course of Calspan Corporation would provide helpful information for building our national impulse facility and de-veloping test measurement tecnology.
