In this paper a strong coupled CFD-CSD method is developed to simulate the aeroelastic phenomena. The CFD solver is based on the finite-volume algorithm for the Navier-Stokes equations on unstructured grid. The CSD solver solves the aeroelastic governing equations in the modal space. Their coupling is realized by a dual-time method. The spring-based smoothing method is adopted to deform and regenerate the aerodynamic grid. Two test cases are selected to validate the authors' method for static and dynamic aeroelastity .The results of the simulation for the static aeroelastic problems of a missile wing show that the Lift Coefficient and Drag Coefficient are severally 7% and 5% lower than those don't consider the elasticity of the wing. The results for the flutter boundary prediction of the AGARD 445.6 wing have been proved much closer to the experiment than using the DLM. This method can describe the effects of fluid viscosity more exactly for highly nonlinear transonic flight conditions. The calculation has proved reliable in the subsonic regime but not accurate enough in the supersonic regime. 2011 IEEE.

To achieve an optimum scan area and target stay time for Roll-Swing imaging seeker the scanning process is analyzed. The method of ground imaging area calculation is proposed in this paper. A kind of Roll-Swing imaging frame mechanism is introduced. The flight process simulation base on real flight data is realized. According to imaging sensor parameters and flight data a new scan scheme method is proposed and a new scan scheme is designed. The new scan scheme is compared to traditional scan scheme from different guide lines. The test results indicate that the new scan scheme satisfy requirement of the real flight experiment. 2010 IEEE.

Small aircraft often used RS485 bus. But with the complexity of the small aircraft's subsystems increase and the progress of field bus technology CAN bus systems in small aircraft use more and more widely. How to record real-time flight experiment data on the small aircraft's CAN bus and provide test data for reproducing the process of a small aircraft flying is very important. This paper presents a design method of signal acquisition device it can be used for small aircraft flying field experiment. 2010 IEEE. as the main chip with DSP2812 SJA1000 as CAN controller CTM1050 as the CAN transceiver CF card as storage media. Gives the diagram of its hardware and software design process. Combined with the background of a small aircraft testing the instrument for data acquisition when the ground experiments and flight progress. Experimental data show that the design of high reliability and CAN signals can effectively complete the record

In order to meet special requests of optical imaging sensor in scene matching navigation system a disc varifocal mechanism is proposed for the flight vehicles of long flying time and range. Within small space occupied it can obtain real images with various resolutions. Moreover using plate traveling-wave Ultrasonic Motor as its driven motor can reduce energy loss improve control precision and ensure image obtaining being real-time and stable. Disc varifocal mechanism driven by plate traveling-wave Ultrasonic Motor is high-response and variation in load doesn't affect its performance parameter. Therefore applying disc varifocal mechanism in scene matching navigation system combing software and hardware can obviously improve the accuracy real-time and robust of scene matching navigation system. The experiment showed that when the weight of mechanism was 1.5kg the shortest starting was 0.6ms and the shortest shutoff was 0.5ms. 2009 IEEE.

Application Research of Intelligent Algorithm in Electric-driven Flight Simulation Turntable is discussed in this paper. Fuzzy control is used to solve the problem of fast tracking and overshoot since its essence belongs to PD control In order to improve the performance of system in low speed a method named variance-gain adaptive algorithm is introduced in this paper. It defines the amplifier gain as a function whose independent variable is speed so the amplifier gain can automatically be adjusted with the change of speed. When the turntable runs at low speed it has a big amplifier gain a good rigidity and high tracking accuracy. When the turntable runs at high speed the method can control the amplifier gain and ensure the system dynamic performance. Design and implementation of these algorithms is introduced in detail. Experiment results show that the Flight Simulation Turntable has achieved the required performance through using fuzzy control algorithm and variance-gain adaptive algorithm. 2008 IEEE.
