Design and Development of Variable Pitch Quadcopter for Long Endurance Flight
Wu, Xiaonan (2018-05-01)The variable pitch quadrotor is not a new concept but has been largely ignored in small unmanned aircraft, unlike the fixed pitch quadcopter which is controlled only by changing the RPM of the motors and only has about 30 ... -
Evaluation of Hybrid-Electric Power System Integration Challenges for Multi-Rotor UAS
McKinney, Kristen Elise (2018-05-01)The modern standard for multi-rotor unmanned aircraft system (UAS) propulsion is an electric configuration typically consisting of battery-powered electric motors. The primary issue with this type of propulsion system is ... -
Experimental Investigation of Drag Reduction on Automobiles with an Inflatable Boat-Tail
McNamara, Kathleen (2018-05-01)There is a growing demand for higher efficiency and more environmentally friendly vehicles, including better fuel economy, reduction in wind noise level, and greater vehicle performance and dynamic stability. These factors ... -
Flight Characteristics of a Tilt-Wing, Distributed-Propulsion, Vertical Take-Off and Landing Aircraft Concept
Whyte, Seabrook (2018-05-01)Unmanned aircraft are starting to be utilized in a diverse set of applications ranging from military surveillance to railroad inspections and natural disaster damage assessment. Given the nature of these missions, runways ... -
Plasma Flow Control for Distortion Tolerant Fans with Aircraft Boundary Layer Ingestion
Zimbelman, Tyler (2018-05-01)Recent efforts to reduce commercial transport aircraft drag include embedding an aft-mounted engine into the airframe in order to fill the vehicle wake with engine exhaust, consequently reducing fuel consumption. Embedded ... -
Preparation and Characterization of Polyethylene-Oxide (PEO) Solution
Lander, Marcus (2018-05-01)For years, it has been known that the addition of a small amounts of polymers, or other materials, to water or other liquids can help reduce the skin friction of a general liquid when flowing past a solid surface, known ... -
Self-Aspirated Vortex Generator Jet Application for Propeller Boundary Layer Separation Suppression
Bellcock, Andrew C. (2018-05-01)This paper presents a novel propeller flow control design to suppress boundary layer separation for improved propeller performance at low Reynolds number conditions or highly loaded operation. The design includes a series ...
