An Unmanned Lighter-Than-Air Platform for Large Scale Land Monitoring

Self-Assembling Intelligent Lighter-than-air Structures

Through the use of flying automata (aerobots), the [ VOILES | SAILS ] project aims to port to the physical world some of the functionalities observed in artificial life systems, with a particular focus on simulations of assemblages and behaviors derived from the observation of animal societies (coral reefs, anthills) that can collectively produce high performance structures with extremely limit...

Lighter than Air Craft Using Vacuum

Ever since his earliest times, man must have dreamed of copying the birds; of flying, of gaining mastery over the third dimension of space. The earliest practicable route to achieve the aim of flying was in the use of balloons. The first balloons were hot-air balloons; they relied on the lower density of hot air, compared to that of the surrounding air, to obtain the lift they needed. Balloons ...

[Proceeding] Innovative Piloting Technique for a Semi-Autonomous UAV Lighter-Than-Air Platform Simulator

Dynamic Response to Turbulence of Tethered Lighter-Than-Air Platforms

The study presented in this paper concerns the development of an algorithm, based on finite element analysis, for the dynamic simulation of a tethered lighter-than-air balloon when subjected to operational conditions. The main features of the algorithm are described, highlighting the advantages of this approach when performing dynamic analysis. The input parameters considered in the method are ...

Lighter than air: heliox breathing improves exercise tolerance in COPD.

D yspnoea and reduced exercise tolerance are the hallmarks of chronic obstructive pulmonary disease (COPD). In the advanced phases of the disease the ability to exercise is mainly limited by the combination of a reduced ventilatory capacity, increased ventilatory requirement and lung dynamic hyperinflation. Importantly, the aforementioned respiratory mehanical abnormalities are well recognised ...
