Aerodynamic Analysis Of Low Speed Wing Design Using Taguchi L9 Orthogonal Array, Kenneth Witcher, Ian Mcandrew, Elena Vishnevskaya
Publications
The study of aerodynamics has been preoccupied with understanding flight at increasing speeds and ultimately supersonic. Today, this pursuit has advanced the science for both Hypersonic and Transonic flight to near Mach 1 supporting economical commercial flight operations. This research presents the data from a Taguchi array on low speed with twin wing designs to establish the design parameters for their use in low speed and high altitude. Also presented is how aerodynamic advantages can be achieved through understanding the interactions of parameters and their use. This is compared to operational effectiveness when applied to remotely piloted aircraft that are …

Take-Off Characteristics For Naca 4612 Aerofoil In A Twin-Wing Configuration With Optimum Angles Of Attack, Elena Vishnevskaya, Kenneth L. Witcher, Ian R. Mcandrew
Publications
Unmanned Aerial Vehicles are used generally at low levels and speeds. The research reported in this article investigates the possible use of twin-wing designs for higher altitudes with a focus on the possible lift capable for either short runways or high payloads. The wing aerofoil and unique Angles of Attack, AoA, are set 5o on the upper wing and 10o on the lower. There is a positive upper wing stagger of 50% of the chord length at height separation of 1 chord. These parameters have been established from previous research and this research investigates how they generate lift at take-off …

How Nationality, Weather, Wind, And Distance Affect Consumer Willingness To Fly In Autonomous Airplanes, Nadine K. Ragbir, Bradley S. Baugh, Stephen Rice, Scott R. Winter
Publications
Several studies have examined passengers’ trust in human-operated systems versus autonomous systems. Prior studies have also reported cultural differences among individuals from India and the United States. The purpose of this study was to investigate how nationality, weather, wind, and distance affect passengers’ willingness to fly in autonomous aircraft. Participants included 161 volunteers from the United States and 137 volunteers from India. In 12 different conditions, participants were asked to rate their willingness to fly in an autonomous aircraft, given information about the weather (sunny, raining, or snowing), the wind level (no wind versus strong wind), and the flight distance …
Robust Nonlinear Estimation And Control Applications Using Synthetic Jet Actuators, 2018 Embry-Riddle Aeronautical University
Robust Nonlinear Estimation And Control Applications Using Synthetic Jet Actuators, Natalie Ramos Pedroza
Doctoral Dissertations and Master's Theses
Limit cycle oscillations (LCO), also known as utter, cause significant challenges in flight control of small unmanned aerial vehicles (SUAVs), and could potentially lead to structural damage and catastrophic failures. LCO can be described as vibrational motions in the rocking, pitching and plunging displacements of an aircraft wing. To address this, the use of synthetic jet actuators (SJAs) in UAV flight control systems is becoming popular as a practical alternative and to mechanical deflection surfaces.
Synthetic jet actuators are promising tools for LCO suppression systems in small UAVs due to their small size, ease of operation, and low cost. Uncertainties …
Design And Optimization Of Aircraft Configuration For Minimum Drag, 2018 Myanmar Aerospace Engineering University, Myanmar
Design And Optimization Of Aircraft Configuration For Minimum Drag, Zin Win Thu, Aung Myo Thu, Phyo Wai Thaw
International Journal of Aviation, Aeronautics, and Aerospace
This paper presents a reliable and robust optimization for minimum drag of an aircraft at the conceptual design phase. Firstly, the conceptual design code was developed and existing Single Seat Aerobatic (SSA) aircraft was chosen to validate the reliability of developed code. The resulted data from the developed code showed good agreement with the existing data. Secondly, Sequential Quadratic Programming (SQP) optimizer was created and employed as a tool to explore possible aircraft configurations that are more efficient and less costly than an existing design. The optimized results gave lower Drag and better performance.
A Novel Approach For Missing Combat Support Aircraft Search Acceleration Using Vtol Uas, 2018 Kazan National Research Techincal University
A Novel Approach For Missing Combat Support Aircraft Search Acceleration Using Vtol Uas, Mohammed Ba Zuhair, Wisam Yousef, Issam Samara, Vladislav Varsegov
International Journal of Aviation, Aeronautics, and Aerospace
In this paper, an approach to accelerate search operations for a missing combat support aircraft using a portable waterproof autonomous vertical takeoff and landing unmanned aerial system called “flying locator beacon” is described. The latter is connected with both flight data and cockpit voice recorders with a parallel bus and may be deployed from the empennage during extreme emergency scenarios, which is detected when few flight parameters are overrun leading to an air crash stimulating behavior. Landing of the flying locator beacon strictly takes place on global latitude and longitude coordinates only of integer values enabling significant minimization of search …

The current article aims at introducing a novel dodecacopter multirotor design called Bulgarian Knight. The aircraft implements a number of innovations and characteristics that give it an advantage over other contemporary multi-copters. Some of its novel characteristics are the mounting of the rotors under the fuselage by use of pusher propellers. Further, the design implements twelve rotors positioned in an optimal geometric coverage.

United States Drone Laws, 2017 Embry-Riddle Aeronautical University
United States Drone Laws, Jacob Crittenden
Student Works
The purpose of this Directed Study was to investigate and compile the drone laws that exist within the United States, both on the federal level and for each individual state. The federal laws are directed by the Federal Aviation Administration (FAA) under laws that pertain to “Unmanned Aircraft Systems” (UAS) and are relatively new. Most states have further regulations on UAS that they have passed. Most of these laws are in place to protect public safety and privacy, but some also prohibit certain locations of flight and certain modifications that might be made to the platform. State laws that limit …

Unmanned Aerial Vehicle (Uav): Flight Performance, Fevens Louis Jean
Student Works
It is important that when measuring the sideslip angle and angles of attack during flight test performance of a UAV (Unmanned Aerial Vehicle), to fully understand that the Angles of attack and sideslip are parameters that aid in determining the safety of the flight as they improve stability and control of the aircraft. The disadvantage of the measurement of these angles using this method is low accuracy of measurement due to friction to the potentiometers in connection with the vanes. To counter this, a new sensing method was developed to minimize friction and collect more accurate data. The method is …

STAR Program Research Presentations
Fisher (Pekania pennant) belongs to the weasel family. In October 2014, the United States Fish and Wildlife Service proposed to list the West Coast Distinct Population Segment of fisher as threatened under the Endangered Species Act. We wish to better define where fishers live within their habitats and use that information to improve conservation efforts. Previously, to track the behavior of wild fishers, researchers put tracker collars on the animals and relied on networks of fixed antennas on the ground in the environment to collect data. We are experimenting with using unmanned aerial vehicles (‘drones’) to collect data …

Static Testing Of Propulsion Elements For Small Multirotor Unmanned Aerial Vehicles, Robert W. Deters, S.C. Kleinke, Michael S. Selig
Publications
The growing use of small multirotor aircraft has increased the interest in having better performance results especially with the propulsion system. The size of the propellers used on these aircraft operate at low Reynolds numbers that are typically less than 200,000. Static performance testing of ten propeller pairs (tractor and pusher) were completed and is the beginning of a systematic test of propellers used on multirotor systems. The propellers chosen for this initial set of tests were selected from four popular quadrotors. Besides testing the propellers provided with the aircraft, propellers that are sold as replacements from third-party companies were …
