摘自23日航空报关于航空发动机试验基地的新闻
为满足国防武器航空装备和民用发动机发展需求，在中央领导和各部委、集团公司领导关心和大力支持下，“十五”期间科工委批准了2号高空舱的建设立项，该项目是航空发动机行业内单台投资最大的建设项目。2号高空舱建成之后，不仅可以满足我国新一代发动机研制高空模拟实验的需求，而且能缓解现在的SB101高空舱试验任务繁重的压力，还能拓展SB101高空台的设备能力。
2号高空舱建设是一个复杂的系统工程，时间紧任务重，院成立了总设计师系统，总工艺师系统，以焦天佑为总设计师、王惠儒为副总设计师的项目团队在开展主体设备的设计中，有许多重大技术创新点：使用弹簧片支座随动架热胀冷缩浮动的推力测量台架，推力测量误差更小；采用内外前室和“环向回流＋理想型面收缩”的供气方式，发动机进口流场品质更好，试验范围更宽而投资更少；采用附面层抽除装置，提高进口流场均匀度；采用排气引射装置，可提高发动机排气环境压力的调节精度和调节速度等。2号舱的设计，既吸收了国外高空台的先进技术，又融合了我国1号高空舱的设计技术和使用经验，处于国际领先水平。
汶川地震后，2号舱将迁至绵阳航空发展试验研究基地建设。2号舱建成之后，加之业已建成的用于涡轴/涡桨发动机高空模拟试验的SB121高空台，以及与高空台配套的各类地面台、移动试车台和辅助设施，将形成高空台群。从而，可以模拟不同空气流量、高度和马赫数的飞行环境条件，能够满足我国今后数十年各型涡喷、涡扇、涡轴、涡桨发动机的高空模拟试验。

From the 23 reported on the aero-engine air test site news
To meet the air defense weapons and equipment and civil engine development needs, and various ministries in the central leadership, the company under the leadership of care and support, "fifteen" was approved during the Commission of Science, 2 high-altitude chamber of the construction project, the project is the air the engine industry's largest single investment projects. 2 high-altitude cabin was built, not only to meet the development of a new generation of high-altitude simulation engine needs, but now the SB101 can ease the heavy task of high-altitude cabin pressure test, but also expand the capacity of SB101 device at high altitude platform.
2 high-altitude cabin construction is a complicated systematic project, tight heavy task, the hospital established a chief architect of the system, with a total technology division system to Jiaotian You as the chief designer, Wang Huiru deputy chief designer of the project team in carrying out the main equipment design, many major technological innovations: using the spring action frame with the expansion and contraction of the floating bearing thrust measurement stand, thrust measurement error smaller; use inside and outside the front room and the "ring back + the ideal surface contraction "of the air supply method, the engine inlet flow field of better quality, less test a wider range of investment; using extraction boundary layer device to improve the inlet flow field uniformity; using exhaust ejector device can improve the engine emission regulation of gas pressure on the environment and adjust the speed accuracy and so on. 2 compartment design, both the absorption of foreign advanced technology, high-altitude stations, but also combines the No. 1 high-altitude chamber of the design technology and experience, in the international advanced level.
Wenchuan earthquake, Mianyang 2 module will be moved to bases Aviation Development Study. 2 cabin was built, in addition has been built for turboshaft / turboprop engine high-altitude high-altitude simulation test of the SB121 units, as well as high-altitude platform supporting all kinds of ground units, the mobile test units and support facilities, will form a high-altitude platform group. Thus, can simulate different air flow, the flight altitude and Mach number of environmental conditions, can meet various types of the coming decades, turbojet, turbofan, turboshaft, turboprop engine altitude simulation test.
