Unmanned Aircraft Systems


Book Description

Unmanned Aircraft Systems delivers a much needed introduction to UAV System technology, taking an integrated approach that avoids compartmentalising the subject. Arranged in four sections, parts 1-3 examine the way in which various engineering disciplines affect the design, development and deployment of UAS. The fourth section assesses the future challenges and opportunities of UAS. Technological innovation and increasingly diverse applications are two key drivers of the rapid expansion of UAS technology. The global defence budget for UAS procurement is expanding, and in the future the market for civilian UAVs is expected to outmatch that of the military. Agriculture, meteorology, conservation and border control are just a few of the diverse areas in which UAVs are making a significant impact; the author addresses all of these applications, looking at the roles and technology behind both fixed wing and rotorcraft UAVs. Leading aeronautical consultant Reg Austin co-founded the Bristol International Remotely Piloted Vehicle (RPV) conferences in 1979, which are now the longest-established UAS conferences worldwide. In addition, Austin has over 40 years' experience in the design and development of UAS. One of Austin's programmes, the "Sprite UAV System" has been deployed around the world and operated by day and night, in all weathers.




"Flying Fox" Remotely Piloted Vehicle


Book Description

This project is a continuation of work done by Daniel Owbridge, whose project on power plant design gave a short list of viable power plants for the "Flying Fox" remotely powered vehicle. The "Flying Fox" is a large, low speed radio controlled aircraft that is to be fitted with video cameras and still photography equipment to be used by the University biology department for flora and fauna surveys in remote, inaccessible terrain.




Power Plant and Drive Train Improvements of the NPS Hummingbird Remotely Piloted Helicopter


Book Description

Originally designed as a target drone for the U.S. Army, the NPS hummingbird has undergone several modifications to convert it into a reliable research platform. The 163 pound remotely piloted helicopter (RPH) is powered by a Weslake Aeromarine Engines Limited (WAEL) 342 two stroke, twin cylinder, 25 hp, gasoline engine. An engine failure due to cylinder overheating halted research efforts until investigation as to the cause and subsequent corrections could be made. Costing approximately $3000 per engine, another failure is unacceptable. The tasks undertaken in this thesis were to investigate the cause of the overheat failure and improve the engine cooling system. Cooling system corrections required total redesigns of the engine cooling and engine start systems. Additionally, research of the RPH's history revealed a need for a torsional shock absorber to be incorporated in the drive train to increase component life. The changes made to Hummingbird provide a decrease in empty weight, minimal center of gravity change and, most importantly, an increase in user safety finishing the Department of Aeronautics and Astronautics with a dependable vehicle for rotary wing research.
