The continued increasing air traffic demand and the corresponding fuel consumption urge the innovations of technologies and operating modes in commercial aviation community. Formation flight, due to its potential for reducing fuel use, are widely recognized as one of the most effective ways to improve aviation fuel saving. This study addresses the commercial formation coalition problem under in...

Formation flying of clusters of micro-, nanoand pico-satellites has been recognized to be more affordable,robust and versatile than building a large monolithic satellite in implementing next generation space missions requiringlarge apertures or large sample collection areas and sophisticated earth imaging/monitoring. We propose a propellantfree, thus contamination free, method that ...

Cognitive Formation Flight in Multi-Unmanned Aerial Vehicle-Based Personal Remote Sensing Systems

Long-term spaceflights induce bone loss as a result of profound modifications of bone remodeling, the modalities of which remain unknown in humans. We measured intact parathyroid hormone (PTH) and serum calcium; for bone formation, serum concentrations of bone alkaline phosphatase (BAP), intact osteocalcin (iBGP), and type 1 procollagen propeptide (PICP); for resorption, urinary concentrations ...

A Multi-Agent System(MAS) consensus based algorithm is proposed for Multi-UAVs to maintain a specified time-varying geometric configuration for formation flight in 3-D space. Use decoupling characteristics in altitude control of Multi-UAVs, formation problem in 3-D space, was decomposed altitude control and plane control. In this approach, the proposed control strategy requires only the local n...

the air transport industry is seeking to manage risks in air travels. its main objective is to detect abnormal behaviors in various flight conditions. the current methods have some limitations and are based on studying the risks and measuring the effective parameters. these parameters do not remove the dependency of a flight process on the time and human decisions. in this paper, we used an hmm...
