Design And Manufacture 6 hours Endurance UAV (Unmanned Aerial Vehicle )

تاریخ : جون ۲۰۱٦ - جون ۲۰۱۷

Fixed unmanned aerial vehicles have recently found both civilian and military applications, with overwhelming focus on the former. A particularly high need has developed for UAVs with continuous area coverage capabilities. There are several industries in which these vehicles would be useful; however, few options are available for the customer at an affordable price. In recent years, there has been a realization among aircraft manufacturers and the public of the enormous potential that exists in a civilian UAV market. One such industry are the land development companies and agencies. DHA City Project in Karachi is a “smart city” being customized to highly urbanized modern living. A requirement for such a grand scheme is high resolution mapping of the land, which due to its expanse can only be done efficiently with a mechanical engine powered fixed wing UAV. This work described the computer aided design and optimization of this solution. Baseline design is achieved through first principles methods and the design is further refined based on extensive simulations and genetic algorithms. URAAN UAV is designed to provide endurance up to 6 Hours having a payload of 12 lbs. It will be able to take-off from small runways as short as 1000 feet. Current estimates give the take-off gross weight as 38 lbs. and wing span of 10 feet. URAAN features an unconventional two surface design featuring top mounted main wing and a horizontal stabilizer, that provide several advantages in terms of stability, stall safety, and fuel savings. The mediocre aspect ratio main wing allows URAAN to loiter on station for nearly 6 hours and have a range of nearly 100 nautical miles. Our UAV will also feature a pusher-propeller engine to minimize vibrations and electrical interference to the camera payloads. The engine will have a power of 4.1 hp.
