This paper create a full aircraft flight simulation model for accurately analyzing the performance and influence of landing gear system. The use of multi-domain modeling technology enables detailed modeling of the flight dynamic and landing gear dynamic. 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. The parameter design space is easily searched by considering a number of different landing scenarios to optimize the design. the authors.

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.
