Active system safety approach for aviation is presented. An implementation scheme using a typical aircrafts structure is discussed with requirements, models and algorithms, hardware and software features. A reliability gain of the active system safety approach is analyzed. It is shown how active system safety model of an aircraft is organized and features of the main dependency matrix are descr...

Purpose of research. Development a methodology for determining deviations pilotless aircrafts from given trajectory in conditions signals loss navigation satellites. Methods. The technique is based on functional relationship between deviation parameters and changes longitudinal transverse parallaxes overlapping images the underlying surface due to these deviations. Mathematical description comp...

Increase on the demand of telecommunication services is related with systems based on different technological alternatives. One of them, that is being developed in the last years is the use of aircrafts or airships technologies. The High Altitude Platforms Stations (HAPS) represent one attractive option today. In this paper, a switched channel model in L band based on HAPS is proposed and analy...

Industrial systems, like aircrafts or cars, are based on real-time distributed networks and require high level of robustness, reliability and adaptability. This paper first introduces our approach to implement a distributed monitor of real-time properties, and then introduce a new formalism, adaptive Petri nets, that will allow to model such complex, distributed and realtime systems. Keywords—D...

More than 100 of the worlds most potent fighter aircraft are depicted in superbly detailed cutaway drawings: from the canvas-and-string contraptions of World War I to the amazing stealth fighters that are taking air combat into the 21st century. Accompanied by fascinating technical and developmental descriptions, each drawing reveals and clearly identifies the aircrafts airframe structures, eng...
