2015-2016 Eraudb Aiaa Design/Build/Fly Technical Report, Trevor W. Perrott

Student Works

The economic potential of small unmanned aerial vehicles (SUAVs) has been well documented and reported. According to the Association for Unmanned Vehicle Systems International (AUVSI), there is an associated economic impact from the growth of the UAV industry. The goal of the American Institute of Aeronautics and Astronautics Design/Build/Fly Competition Research Program (AIAA DBF CRP) is to investigate design and manufacturing methods for application to SUAVs within the scope of the AIAA DBF Competition.

Students were engaged in the application of aerospace engineering knowledge for the production of a dual-aircraft system. Through the use of Computational Fluid Dynamics (CFD), Computer …

Suitability Testing For Possum Scientist-Astronaut Candidates Using The Suborbital Space Flight Simulator With An Iva Spacesuit, Pedro J. Llanos, Erik Seedhouse, Ryan L. Kobrick

Publications

This paper evaluates key functional data parameters that must be considered for suborbital spaceflight participants wearing pressurized suits for intravehicular activity (IVA). Data parameters of an analog spacesuit worn in an analog flight environment were obtained from 40 civilian participants using the Suborbital Space Flight Simulator (SSFS) at Embry-Riddle Aeronautical University (ERAU) while donning Final Frontier Design’s (FFD) fully pressurized third-generation spacesuit as part of their training for Project PoSSUM (the Polar Suborbital Science in the Upper Mesosphere Project). The physiological data collected included: blood pressure, electrocardiograms, heart rate, grip strength, and skin temperature. These parameters were measured using a …

Hybrid Magneto-Active Propellant Management Device For Active Slosh Damping In Spacecraft, Balaji Sivasubramanian, Leander Paul, Sathya Gangadharan

Publications

This disclosure includes a hybrid magneto-active membrane, which can be used as part of a Magneto-active Propellant Management Device (MAPMD), to actively control free sur­face effects of liquid materials, such as fuels, and to reduce fuel slosh. The disclosed MAPMD merges aspects of a dia­phragm membrane with a magneto-active inlay to control the membrane during in-flight conditions.

Standardization Of Human-Computer-Interface For Geo-Fencing In Small Unmanned Aircraft Systems, David Thirtyacre, Robert Brents, Michael Goldfein, David Hunter, B. Terwilliger

Publications

The use of small unmanned aircraft systems (sUAS) has increased significantly in the past year. Geographic fencing (geo-fencing) is software built into most medium-cost consumer sUAS. This software is typically used to limit the altitude above launch point, the flight distance from the transmitting controller, and/or restrict flight inside a no-fly zone. While the concept of a geo-fence is simplistic, the human-computer-interface (HCI) varies drastically among platforms, and even between software iterations on the same platform. This research examines the HCI of three popular consumer-level sUAS with regard to geo-fencing. The software procedures and human interface for the DJI Inspire-1, …

Electrically Coupled Counter-Rotation For Gas Turbine Compressors, Vinod Gehlot

Publications

A system and method for implementing stage-by-stage counter rotation in a multi-stage axial compressor of a gas turbine engine. The system includes an electrical power gen­erator and an electric motor. A turbine-driven shaft connected to an armature of the electrical generator drives a first plural­ity of compressor blades. The electrical generator armature induces changing magnetic flux in the stator coils of the electrical generator which generates electrical power that is sent to a power control module. The power control module controls the electrical motor and excites the coils in the elec­tric motor stator which drives the electric motor armature. The …

Multi-Stage Axial Compressor With Counter-Rotation Using Accessory Drive, Vinod Gehlot, Magdy S. Attia

Publications

A multi-stage axial compressor for counter rotation. A first series of rotor blade assemblies are mounted on and rotate with the driveshaft, each rotor blade assembly of the first series comprising a rotating stage of the multi-stage axial compressor. A second series of rotor blade assemblies pro­vide a counter-rotating stage of the multi-stage axial com­pressor. An accessory drive links the second series of rotor blade assemblies to the driveshaft and causes counter-rotation of the second series of rotor blade assemblies.

Software Defined Multi-Spectral Imaging For Arctic Sensor Networks, Sam B. Siewert, Matthew Demi Vis, Ryan Claus, Vivek Angoth, Karthikeyan Mani, Kenrick Mock, Surjith B. Singh, Saurav Srivistava, Chris Wagner

Publications

Availability of off-the-shelf infrared sensors combined with high definition visible cameras has made possible the construction of a Software Defined Multi-Spectral Imager (SDMSI) combining long-wave, near-infrared and visible imaging. The SDMSI requires a real-time embedded processor to fuse images and to create real-time depth maps for opportunistic uplink in sensor networks. Researchers at Embry Riddle Aeronautical University working with University of Alaska Anchorage at the Arctic Domain Awareness Center and the University of Colorado Boulder have built several versions of a low-cost drop-in-place SDMSI to test alternatives for power efficient image fusion. The SDMSI is intended for use in field …

Cognitive Loading, Affect Regulation And Aerodynamic Considerations In Uninhabited Aerial Vehicle Systems Refueling Operations, Sam Holley, Ian R. Mcandrew

Publications

Factors influencing aerodynamics involved in aerial refueling illustrate the potential for specialist operators to manage these operations for remotely piloted vehicles. The authors review aerodynamic characteristics of uninhabited aerial systems during refueling, drogue and boom design and associated flight dynamics, cognitive factors associated with control transfer and refueling, and affective components and their influence on decision making and operator performance. Attention is directed to cognitive loading and encoding challenges, with considerations for hippocampal mapping and hemispheric asymmetry. Implications for system state awareness are examined. Advantages for specially trained refueling pilot operators are discussed and recommendations given for areas of concentration.

System And Method For Location Of Aircraft, Albert D. Helfrick

Publications

A system and method are provided that includes an aircraft secondary radar transponder activity detector that monitors an aircraft's transponder transmissions and activates an emer­gency locator transmitter to begin transmitting should the aircraft transponder transmissions cease to help locate an aircraft that may have become undetectable by conventional aircraft surveillance and tracking systems.

Hybrid Clutch Assembly For An Aircraft, Richard Anderson, Charles N. Eastlake, Matt Gonitzke, Glenn P. Greiner

Publications

A hybrid clutch assembly inserted between an internal com­bustion engine and the propeller of an aircraft to provide a hybrid-powered aircraft. The hybrid clutch assembly allows a direct current (DC) electric motor to be attached to the hybrid clutch assembly using drive belts. The hybrid clutch assembly allows the internal combustion engine to transmit power to the aircraft's propeller and freely spin the DC motor. The DC motor can transmit power to the aircraft's propeller without turning the internal combustion engine. The hybrid clutch assembly independently allows either the internal combus­tion engine or the DC motor in parallel to power …

Lift & Drag Reductions On Iced Wings During Take Off And Landing With Unmanned Aerial Vehicles, Ian R. Mcandrew

Publications

This research paper addresses an novel problem that has not been addressed in detail for many decades. Ice formation on aircraft has procedures and protocols to deal with expected and actual problems. Complex modern aircraft are equipped with a variety of techniques to remove Ice formation on an aircraft, especially the wings. The introduction of Unmanned Aerial Vehicles has added an old problem, that of low speed and the lack of power to overcome losses in lift through ice formation. In this research the different types of Ice formation, how they combine and affect Lift and Drag are also addresses …
