The impact of the solar-powered range-extending coefficient, endurance time, and other key parameters on the overall parameters of the UAV such as cruise speed, wing load and payload coefficient is discussed. To verify the method, a hand-launchable UAV with a wingspan of 3.2 m was designed ...
The results demonstrate that neglecting the influence of UAV development costs would be imprudent. By appropriately adjusting design parameters using the optimization algorithm, significant reductions in UAV development costs can be achieved with minimal performance losses. 展开 关键词: UAV, Development ...
research and design a set of UAV cargo information collection and environmental monitoring system solutions suitable for dangerous goods warehouses, to carry out real-time recording and monitoring of a variety of environmental parameters for the dangerous goods in the storage of the warehouse, and rea...
(HALE) unmanned aerial vehicles (UAV).Design/methodology/approach - By depicting solar power distribution on earth, along with the efficiencies analysis of photo-voltaic cells (P-cell) and lithium-sulfur battery (LS-battery), the influence of energy to concept design parameters is analyzed first....
The semi-monoque structure consists of one main mono-spar, 4 major ribs, carbon tubes and a flap. The internal structures have been designed to promote better flight and structural performances. Wing loading calculations were done based on the parameters given under regulations of FAR Part 23: ...
A predator–prey particle swarm optimization (PSO) algorithm for identifying parameters of UAV flight control system is presented, with the aim of reducing the workload of the designers during the process of designing complicated UAV control system. Besides, a software environment for UAV controller ...
lamps. In addition, the energy consumption of the UAV perching system when perching on objects can be reduced to 0.015 times that of hovering. Fig. W1Diagram of the inverted crank slider mechanism.aSome important parameters ...
For an unmanned aerial vehicle( UAV) with high-mounted wings,a simplified analytical model is established to analyze the cushioning characteristics of a soft landing airbag system and determine the initial design parameters of the soft l... W Cai,LI Bin,JP Wen,... - 《Acta Armamentarii》 被...
UAV System design Performance 1Introduction A wireless sensor network is defined as a collection of devices capable of sensing environmental parameters, connected in a network and collectively delivering the collected data to a certain location. As a result of more than a decade of investigations, th...
Prototype of the UAV has been manufactured follows the design parameters. The flapping mechanism employed a 2-DOFs revolute-spherical-spherical-revolute (RSSR) system to reflect the flapping attitude of bats. An outdoor test flight was then processed with the manufactured prototype. Onboard flight ...
