This paper create a high fidelity plant model of an aircraft landing gear to inclusion into a full aircraft flight simulation for accurately analyzing the performance and influence of landing gear system. The use of domain specific modeling software enables detailed modeling of the physics and facilitates accurate computational simulation of the flight dynamic  aerodynamic  landing gear dynamic and mechanical loads that occur when the landing gear are deployed and retracted during landing and take-off operations. The parameter design space is easily searched by considering a number of different landing scenarios including touching down on one wheel first  to optimize the design. The simulation results show that the aircraft landing gear system mathematical model established appropriately reflects the change of force and moment in the process of taking off and landing  and it is actual in the physical process. 2011 IEEE.

In order to improve the measuring accuracy of the visible light phase-shifting point diffraction interferometer (PS/PDI) for the extreme ultraviolet lithography (EUVL) aspheric mirrors  the main measuring errors will be discussed in this paper. At first  the elementary configuration and measuring principle of the visible light phase-shifting point diffraction interferometer are introduced briefly  then the different errors which are possible to affect the measuring result are summed up  the errors include PZT phase-shifting error  detector nonlinearity error  detector quantization error  wavelength instability error and intensity instability error of the laser source  vibration error  air refractivity instability error and so on. Through detailed analysis and simulation  the magnitude of these errors can be obtained. By analysing the reasons which cause these errors and the relationship between these errors and interferometer configuration parameters  some methods are put forward to avoid or restrain these errors accordingly.

As we know  the existence of image motion has a bad effect on the image quality of satellite-borne TDI CCD camera. Although many theories on image motion are proposed to cope with this problem  few simulations are done to justify the proposed theories on ground. And thus  in this paper  a ground-based physical simulation system for TDI CCD imaging is developed and specified  which consists of a physical simulation subsystem for precise satellite attitude control based on a 3-axis air bearing table  and an imaging and simulation subsystem utilizing area-array CCD to simulate TDI CCD. The designed system could realize not only a precise simulation of satellite attitude control  whose point accuracy is above 0.1 and steady accuracy above 0.01/s  but also an imaging simulation of 16-stage TDI CCD with 0.1s its integration time. This paper also gives a mathematical model of image motion of this system analogous with satellite-borne TDI CCD  and detailed descriptions on the principle utilizing area-array CCD to simulate TDI CCD. It is shown that experiment results are in accordance with mathematical simulation  and that the image quality deteriorate seriously when the correspondence between the image velocity and signal charges transfer velocity is broken out  which suggest not only the validity of the system design but also the validity of the proposed image motion theory of TDI CCD. 2010 SPIE.
