This paper describes a comprehensive methodology to reduce the power penalties of an Air Supply Unit (ASU) used in Circulation Control Unmanned Aerial Vehicles (UC2AVs). Circulation Control (CC), which is an active flow control technique that can be used on fixed-wing aircraft to achieve lift augmentation, requires the use of an efficient CC system on-board. The experimental testbed for a CC system...
Circulation Control (CC) is an active flow blowing technique that can be used on small scale fixed-wing Unmanned Aerial Vehicles (UAVs) to enhance lift and aerodynamic efficiency, resulting in enhanced payload capabilities. This paper presents a novel, newly introduced controller design for what could be the next generation UAV, the Unmanned Circulation Control Aerial Vehicle (UC2AV). Controller design...
The focus of this paper is on the design, development and evaluation of a framework for a fixed-wing UAV to achieve efficient Circulation Control-based (CC) flights. The research presented in this paper is the natural outgrowth of results reported in [1] related to the design and development of an Air Supply Unit (ASU) and plenum design for CC-based Unmanned Aerial Vehicles (UAVs). The framework consists...
The main contribution of this paper is the design, development and evaluation of a light-weight Air Supply Unit (ASU) and its associated speed controller, suitable for use in Circulation Control Wings (CCW) of small-scale Unmanned Aerial Vehicles (UAVs). An iterative process, presented here, is used to optimize the design of the centrifugal compressor for the ASU through extensive simulation. The...
Circulation Control, which was discovered accidentally by Henry Coanda in 1935, is proven to be an efficient lift augmentation method at low Mach numbers. The objective of this research is to design and develop a Circulation Control Wing (CCW) that will provide increased lift to a fixed-wing Unmanned Aerial Vehicle (UAV). The configuration (the curvature of the trailing edge on a Clark-Y airfoil)...
The focus of this paper is on surveying UAV-based systems for traffic monitoring and management. Although there has been voluminous research on the subject, unmanned aerial vehicles (UAVs) are proven to be a viable and less time-consuming alternative to real-time traffic monitoring and management, providing the eye-in-the-sky solution to the problem.
