Real-time prediction of the air contaminant dispersion is an important issue in hazard assessment and emergency management of air pollution. The conventional atmospheric simulation can seldom give the precise prediction results due to inaccurate input parameters. To improve the accuracy of the prediction of atmospheric model, a real-time data driven atmospheric dispersion simulation based on data...
In order to enhance the mobile penetration ability of anti-ship missiles, according to the anti-ship missile and the ship to air missile combat process, reducing the interception probability of ship to air missile weapon system, the construction of spiral maneuvering anti-ship missile penetration model to air missile weapon system. By studying the extraction methods of miss distance, ship to air missile...
In this paper, a nonlinear dynamic model and multi attitude controllers are developed for Multi-rotor Helicopter. First, different type of Multi-rotor Helicopter and its flight theory is introduced. Secondly, based on the forces and moments on the Multi-rotor Aircraft during its flight, kinematic and dynamic model is founded. Then, the mathematical model is simplified to design attitude controllers...
Oil mist concentration is one of the important factors that influence the state of equipment, so it is very critical to monitor oil mist concentration accurately and quickly. A kind of monitor device is designed to carry on the sampling of the air inside and get the original data. And forecasting the variety of oil mist concentration with grey model, it opens the air decontamination device before...
