High speed air transportation became the most common way of transportation, especially on the long distances. Though very fast and convenient, air transportation is a significant source of pollution: noise pollution and air pollution. The alternative to reduce emissions and noise pollution is to improve the operational performance of the aircraft. In this paper the new ground traction system for the aircraft LTO cycle based on an electric machine is proposed to reduce the pollution.
To hide personnel, equipments and vehicles modern battlefield uses many techniques such as natural and artificial obstacles (e.g. vegetation, and masking and netting, respectively). Even if the enemy would not use these methods there are some situations when conditions like bad weather may make difficult or impossible to visualize these obstacles. To overcome this inconvenience, a stabilized platform made of a complex sensor (visible and infrared camera) and a LASER radar is designed. This paper presents the results obtained in solving this complex problem by using complex data (image) processing not only to find the kind of targets described above, but also to identify them.
As part of a programme investigating the design of new airplanes the aeronautics and automatics engineers are studying aircraft and systems which would operate with greatly reduced stability margins and would, as a result, be totally dependent on computer control for the safety of a flight. Therefore these computer systems generally used to provide active control are required to have efficient diagnosis systems. A fuzzy dual diagnosis system for the command of a commercial airplane is presented.
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.
