Acoustic Characterization of a Multi-Rotor SUAS as a First Step Towards Detection and Identification via Acoustic Signature
Feight, Jordan Ambrose (2017-07-01)In this study, the noise produced by a multi-rotor aircraft is recorded and characterized with the main goal to understand the signature for the use of detection and identification. The need for this technology spawns from ... -
Development of Lightweight, Compact, Structurally-integrated Acoustic Liners for Broadband Low-frequency Noise Mitigation
Chambers, Andrew Thomas (2017-05-01)Airborne noise with a low dominant frequency content (<~500 Hz) has detrimental effects in many applications, but is as yet beyond the scope of conventional acoustic noise mitigation techniques using liners, foams or ... -
Investigation of SOLIDWORKS Flow Simulation as a Valid Tool for Analyzing Airfoil Performance Characteristics in Low Reynolds Number Flows
Wallace, Joseph Scott (2019-05-01)The majority of unmanned aerial vehicles active currently and projected to be active in the future, operate within a low Reynolds number flow regime due to their size and flight envelope. As their popularity and applicability ... -
Low-frequency Acoustic Noise Mitigation Characteristics of Metamaterials-inspired Vibro-impact Structures
Rekhy, Anuj (2016-12-01)Acoustic absorbers like foams, fiberglass or liners have been used commonly in structures for infrastructural, industrial, automotive and aerospace applications to mitigate noise. However, these conventional materials have ... -
Mobile ground test rig for evaluating small-scale turbojet in-flight performance and start reliability
Swart, Colton Ray (2021-05)This paper presents the design and analysis of a mobile ground test rig for small-scale turbojet engines to simulate in-flight start reliability for design changes aimed at increasing the performance of the engine. One of ... -
Portable Recovery System for an Unmanned Aircraft with a Straight Wing and a Tractor Propeller
Delano, Brian A. (2019-07)The recovery system development effort for an unmanned aircraft (UA) has been documented and examined. The development effort existed to satisfy a customer's need to recover an 80 lb aircraft on unimproved terrain. The ...
