- InvestigationThe use of fixed wing UAVs, has gained significant interest in the past few years, in various applications. UAVs of various sizes and capabilities are commercially available.These platforms are stable and easy to use but, applications are restricted by their motor . Although battery technology has improved in terms of power density, specific weight and durability, batteries subsystem remains a critical, heavy item on an UAV. Supercapacitors might be the part of the future hybrid battery/supercapacitors UAVs’ energy supply system, but not at this stage of the development.
- DevelopmentThe development of UAVs continued in fits and starts with some military commanders questioning their usefulness. The attitude towards UAVs changed with the Israeli Air Force’s stunning victory over the Syrian Air Force in 1982. Israel’s coordinated use of manned and unmanned aircraft allowed them to destroy 86 Syrian aircraft in a short time over the Bekaa Valley with minimal losses. Israeli drones were used as electronic decoys, electronic jammers and provided real-time surveillance. It could be argued that this campaign ushered in the modern era of the UAV. These expensive and unreliable “toys” had come of age.
- ProjectMost aeronautical experimenters built models of their designs in order to discover if they would work. This practice is still used today. John Stringfellow and William Henson from England combined their talents in 1848 to build a steam powered propeller driven model aircraft with a 10 foot wingspan called the Aerial Steam Carriage. This model successfully flew for a distance of approximately 60 yards. Another Stringfellow model was flown on a wire guide inside the Crystal Palace of London in 1868. Eyewitnesses reported that the steam powered tri-winged aeroplane generated lift and only used the wire guide to keep from crashing into walls.
