Because of the unique flight trajectory and high penetration effectiveness, near-space hypersonic vehicles (NSHV) become a great challenge for active air defense systems. This paper study the tracking algorithm for NSHV based on Aerodynamic Model. Firstly, the paper simulated flight trajectory of NSHV based on the equation of motion. Secondly, the paper designed a tracking method for NSHV by using...
Formula SAE-China will be held the first time in September, 2010. How to design a suitable front wing for a Formula SAE race car is discussed in this paper. First we choose a series of front wings and study their dynamics property in different attack angle by the method of CFD. Then we put two or three wings together to be assemble wings and study their property. The results are compared and analyzed...
It is a key issue for table tennis robot that the flight trajectory of ball could be rapidly predicted within a certain precision. Due to the nonlinear model of the ball's flight, only all state including the position and velocity at each event are catched, could its whole trajectory be obtained. However, since only the position could be measurable by cameras, the velocity should be predicted by the...
