Design and development of a controllable wing loading unmanned aerial system
Castor, Garret Oakley (2019-12)Vertical takeoff and landing (VTOL) unmanned aerial systems (UAS) offer all the benefits of wing borne flight without the need for conventional takeoff and landing (CTOL) infrastructure. There exists many effective VTOL ... -
Development of a software in the loop simulation approach for risk mitigation in unmanned aerial system development
Johnson, Charles Preston (2020-12)A common method to reduce risk during the development of new designs is simulation and estimation. The extent to which these simulation and estimation techniques can be relied upon for small Unmanned Aerial Systems (sUAS) ... -
Evaluation of a dual-mode, turbojet-turboprop engine for unmanned aircraft
Schinzler, Trey (2022-05)This paper provides experimental feedback on the feasibility of a small-scale, dual-mode turbojet to turboprop engine. The engine used for testing was a KingTech K45-TP. Key parameters focused on for this experiment were ... -
Evaluation of granular distribution and propellant grain length on tri-modal ammonium perchlorate solid rocket motors
Velasco, Daniel (2022-05)This paper presents an evaluation on the effects that variances in ammonium perchlorate particles size, total aluminum content ratio, and solid rocket motor geometry has on tri-modal ammonium perchlorate composite solid ... -
Investigation of a tilt-wing proof of concept for a high-speed VTOL jet UAV using thrust vectoring for balance
Duncan, Britton Ray (2022-12)Success of Special operations forces (SOF) missions depends on a high level of situational awareness within sensitive areas of interest, especially when arriving in volatile, sensitive environments. Oftentimes intelligence, ... -
Mobile Propeller Dynamometer Validation
Morris, Mason Wade (Oklahoma State University, 2013-12-01)With growing interest in UAVs and OSU's interest in propeller performance and manufacturing, evaluating UAV propeller and propulsion system performance has become essential. In attempts to evaluate these propellers a mobile ... -
Practical Guide to the Piccolo Autopilot
Mornhinweg, Anton (2014-07-01)In support of a UAV contract the Piccolo SL and Piccolo II autopilots were installed and operated on various aircraft. Numerous problems with the autopilot setup and analysis processes were found along with numerous problems ... -
Simulation of Supersonic Injection of Underexpanded Aerated Liquid Jet
Choudhari, Abhijit S. (2016-12-01)The present computational study for underexpanded 2D and axisymmetric nozzle configuration is carried out for both gas-only and aerated liquid jet. The study is motivated by the application of fuel injection in air-breathing ... -
Turboprop performance and acoustic evaluation for a small unmanned aircraft variable-cycle engine
Durkee, Matt (2019-05)Range and endurance of small unmanned aircraft systems (sUAS) driven by gas turbine engines are constrained by high thrust specific fuel consumption (TSFC) resulting from low overall efficiency. This study evaluates the ...
