Digital-pheromone-based control method for UAV swarm search

Abstract: The origin,concept,characteristics,importance of a reactive behavior mechanism and the appliance prospect of pheromone are systematically researched.A digital-pheromone-based method for unmanned aerial vehicle(UAV) swarm is designed based on two basic types of biological pheromones.From both overall and individual perspective,a digital-pheromone-based decision-making method for UAV swarm control is established.The basic characteristics of this mechanism are Abstracted,the stability of this kind of mechanism is analyzed and the boundary of swarm is obtained.The simulation result shows that this mechanism is able to form a stable digital-pheromone loop and integrate with the decision making method,which makes UAV group present vivid swarm characteristics,thus realizing UAV swarm search control.Moreover,UAV swarm driven by digital-pheromone is notably superior to formation pattern as for searching for targets,which also proves that the search capacity of UAV swarm is much more superior than that of traditional formation indirectly.

Temperature Effect on Drop-Weight Impact of Woven Composites

Abstract: This paper investigates the effect of temperature on hybrid woven composite panels (100mm×100mm×25mm) which underwent drop-weight impact at five different test temperatures: -60°C, -20°C, room temperature, 75°C and 125°C. The studies were conducted by using experimental and 3-D dynamic finite element approaches. The specimens tested were made of plain-weave hybrid S2 glass and IM7 graphite fibers imbedded in toughened epoxy (cured at 177°C). The composite panels were impacted using an instrumented drop-weight impact tester. The time-histories of impact-induced dynamic strains and impact forces were recorded. The damaged specimens were inspected visually and using the ultrasonic C-scan method.

Supersonic Flow Past a Wedge with a Flame at its Apex

Abstract: The wholly supersonic flow past a two-dimensional wedge is analysed on the assumption that release of chemical energy into the stream can be accomplished across a thin discontinuous plane flame front attached to the apex. Forces experienced by the wedge are calculated and representative flow patterns exhibited. Some typical interactions between the flame and shocks or centred simple waves are discussed, with emphasis on the use of pressure-flow-deflection diagrams to obtain results.
