Starting from the reality of airlines, this paper studies the operational risk and control methods of airlines, establishes relevant risk index system, and formulates corresponding control methods. Based on the four aspects of human, aircraft, environment and management, the risk index system is established. The weight of the index and the score of each system are determined by using the analytic hierarchy process and the fuzzy comprehensive evaluation respectively, and the airline risk evaluation model is established. In the formulation of airline management and control methods, genetic algorithm is used to compare different flight task combinations, and the advantages of this method are obtained.
Low-altitude airspace resources have been the bottleneck of the development of general aviation industry and one of the key factors restricting the development of general aviation in China. Through theoretical research and on-the-spot investigation, this paper constructs a low-altitude airspace resource availability evaluation index system, uses multiple linear regression method to carry out systematic analysis, and determines the index weights at all levels. Taking Jiangsu Province as an example, the present situation of low-altitude available resources in Jiangsu Province is deeply analyzed, the actual situation and a large amount of data in various regions are summarized, the influence values of various factors on the region are calculated, and finally the availability results of low-altitude airspace resources are obtained. The research results demonstrate the scientificity and effectiveness of the method, which can provide reference for the rational utilization of low-altitude airspace resources and the declaration of general aviation activity airspace in China.
At present, the flight training, army operation increase constantly, the army ATC faces rigorous challenges. The safety evaluation on ATC can enhance the control effect and guarantee fly safety. In this paper, an evaluation index system is established based on ‘human factor, machine factor, environment factor and management factor’. On the basis of AHP and cloud model, the safety evaluation model is built. To validate the model, an experiment is operated, the result is accord with the real situation, which proves the scientifically and feasibility of this model.
With the progress of aerospace technology, unmanned aerial vehicles (UAV) are gradually showing incomparable advantages over manned aircraft. However, the safety interval of formation flying has always puzzled us. In order to solve this problem, this paper mainly studies the collision risks of three UAVs in flight considering the two factors of wind and positioning error. It provides a reference for the research on the of flight safety interval UAV formation.
Electronic Jamming is an important means to cover the penetration formation and improve survival probability of penetration aircraft when Air force performs ground penetrating mission. A compound interference method of jamming surface-to-air missile guidance radar by scattering long–range jamming signals though chaff clouds is proposed, which uses jammer to irradiate chaff clouds scattered on the penetration route, and injects jamming energy into the main lobe of surface-to-air missile guidance radar by scattering chaff clouds to make better interference effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
