For the demand of space camera's wide view field and high resolution  the technique of mechanical interleaving assembly is discussed. Its principle  method of adjusting and testing as well as the structure of focal plane are described. Using mechanical tangent-screws adjusting method  the assembly with TDI CCDs for wide field space camera focal plane is finished on the facility which is composed of a long work-distance microscope and a negative pressure and adsorption guide apparatus. The assembly length of TDICCD focal plane for wide field space camera reaches 560mm  and the measuring error is not more than 3.2 m  the mechanical interleaving assembly method has effect of zero clearance and can achieve good image quality.   Development of the facility for model scramjet testing 会议论文  OAI收割 10th AIAA/NAL-NASDA-ISAS International Space Planes and Hypersonic Systems and Technologies Conference 2001, Kyoto, Japan, April 24, 2001 - April 27, 2001 作者:  Chang XY(张新宇);  Chen LH(陈立红);  Yu G(俞刚);  Qian DX(钱大兴) 收藏  |  浏览/下载：27/0  |  提交时间：2017/06/01 Chinese Academy of Sciences  Enthalpy flow  Hypersonic propulsion test facility  Performance tests  Scramjet testing  Supersonic combustion  Total pressure  Total temperatures
