空间相机中与大口径透镜有关的结构设计分析

某空间相机镜头在光学设计时，因透过率、吸收率等原因，为了满足光学系统要求，经过各方面平衡后，其中有一片透镜比正常径厚比设计的偏薄些。在镜头总体结构设计时，单独对该镜片及与之相配的结构件进行了有限元分析和实验检测，发现不同的结构形式对镜片面形影响不同。为了解决这一问题，在实验中进行了探讨，以保证整个相机系统满足空间相机的实用要求。     

面天线检测数据处理方法的探讨

对面天线检测数据处理方法作了一些有益的探讨。从获取被测物的三维坐标后到获取真正有用的信息这一过程需要经过坐标转换和表面误差计算两个步骤 ,其中坐标转换是关键。在坐标转换方面 ,文中提出了曲面自由拟合、公共点转换和CAD面型转换三种方法 ,阐述了这些方法的数学模型 ,并且用实测数据进行了验证计算。理论分析和实际计算两方面显示 :CAD面型转换法既不需要天线的曲面方程 ,也不需要有已知的公共点 ,结果准确、可靠 ,是一种理想的方法 ;如果没有天线的CAD面型 ,但却存在公共点时 ,公共点转换法也是较理想的方法 ,其结果与给定的公共点误差有关 ;如果既没有天线的CAD面型又无公共点或公共点误差很大时 ,只能采用曲面自由拟合法 ,该法准确度最高 ,但容易使天线面型产生错位现象

Effects of Mach numbers on Magnus induced surface pressure

Experimental and numerical methods were used to investigate the Magnus phenomena over a spinning projectile. The pressure force acting on the surface of a spinning projectile was measured for various cases by employing a relatively novel experimental technique. A set of miniature pressure sensors along with a data acquisition board, battery and storage memory were placed inside a spinning model and the surface pressure were obtained through a remotely controlled system. Circumferential pressures of the model for both rotational and static conditions were obtained at two different free stream Mach numbers of 0.4 and 0.8 and at different angles of attack. The results showed the ability of this new test method to measure the very small Magnus force via surface pressures over the projectile. The results provide a deep insight into the flow structure and illustrate changes in the cross-flow separation locations as a result of rotation. Similar results were obtained by the numerical simulations and were compared with the experimental data.     

A surface parametric control and global optimization method for axial flow compressor blades

An aerodynamic optimization method for axial flow compressor blades available for engineering is developed in this paper. Bezier surface is adopted as parameterization method to control the suction surface of the blades, which brings the following advantages:(A) significantly reducing design variables;(B) easy to ensure the mechanical strength of rotating blades;(C) better physical understanding;(D) easy to achieve smooth surface. The Improved Artificial Bee Colony(IABC) algorithm, which significantly increases the convergence speed and global optimization ability, is adopted to find the optimal result. A new engineering optimization tool is constructed by combining the surface parametric control method, the IABC algorithm, with a verified Computational Fluid Dynamics(CFD) simulation method, and it has been successfully applied in the aerodynamic optimization for a single-row transonic rotor(Rotor 37) and a single-stage transonic axialflow compressor(Stage 35). With the constraint that the relative change in the flow rate is less than0.5% and the total pressure ratio does not decrease, within the acceptable time in engineering, the adiabatic efficiency of Rotor 37 at design point increases by 1.02%, while its surge margin 0.84%,and the adiabatic efficiency of Stage 35 0.54%, while its surge margin 1.11% after optimization, to verify the effectiveness and potential in engineering of this new tool for optimization of axial compressor blade.
