Advancing Vtol Tail-Sitter Stability Through Modern Flight Control And System Identification, Tobey Cram, Jacob House, Alexander Theophanis

Discovery Day - Daytona Beach

Title: Advancing VTOL Tail-Sitter Stability Through Modern Flight Control and System Identification   The concept of tail-sitter aircraft can be traced back to Nikola Tesla nearly 100 years ago; however, no aircraft with this novel design materialized until nearly 20 years later during World War II, when efforts were made to reduce reliance on runways. One notable design that emerged during the Cold War was the Convair XFY-1 Pogo. This design failed for reasons common to many others of the time: pilots had extreme difficulty landing while looking over their shoulders, and the technology of the era could not reliably maintain …

Enhancing Fibre–Matrix Interface Properties In Cfrps Using Cohesive Zone Modelling, Arjun Myadam, Alexander Skoppe

Discovery Day - Daytona Beach

Carbon fibre reinforced polymers (CFRPs) are extensively used in aerospace, automotive, and structural applications owing to their high specific strength, stiffness, and design flexibility. The mechanical performance of these composites is critically governed by the fibre–matrix interface, which controls stress transfer and directly influences damage initiation, crack propagation, and fracture behaviour. The interface strength is quantified through the interfacial shear strength (IFSS) and fracture energy, both serving as key indicators of composite integrity. Nanoscale fibre surface modifications are widely employed to enhance interfacial bonding and can also impart multifunctionality, such as capacitive properties, magnetic behaviour, and piezoelectricity. For instance, nanoscale …

Simplified Flight Controls For Urban Air Mobility (Uam), Sierra Martinez, Frank Cunningham Iv, Nicole Giordano, Olivia Honan, Katie Stubits, Heather Bond, Paul Seal, Brandon Ibarra

Discovery Day - Daytona Beach

Air taxis are meant to perform short-distance, lower-altitude flights in challenging terrain- whether it be maneuvering around skyscrapers in urban areas, or for emergency responders in remote, difficult to access areas. It is paramount that the control system is intuitive and user friendly, since air taxi pilots will likely receive less training than commercial airline pilots. The Human Factors Department is working to advance Urban Air Mobility (UAM) initiatives by evaluating alternative inceptors (ie. control systems) that might be used in Vertical Take-Off and Landing (VTOL) air taxi designs. The controller itself needs to have specific and distinct enough operations …

Discovery Day - Daytona Beach

Access to critical medical infrastructure and supplies can be limited in rural and remote communities, where long travel distances and limited transportation networks can delay emergency response/care. In fact, according to the National Library of Medicine, in the United States alone, “about 20% of the US population—more than 50 million people—live in rural areas, but only 9% of the nation's physicians practice in rural communities”, highlighting the challenges many communities face in accessing timely medical resources. Unmanned aerial vehicles (UAVs), however, offer a potential solution by providing fast and flexible delivery of critical life support medical payloads. Project 337, developed …

Trim Characteristics And Its Importance, Daviel Peralta

Discovery Day - Daytona Beach

This project will go into the characteristics that lead to the concept of “Trim adjustment” in aircraft by modeling and demonstrating physical principles and mathematical concepts under ideal conditions. We will derive an equation from the basic physical principles of torque and lift to demonstrate how the trim is adjusted in steady, constant velocity flow for the sake of the pilot’s ease of control and to induce stability in flight. These adjustments are considered differently with different types of aircraft; as such, we will be focusing on mono-fixed-winged aircraft with one engine and conventional helicopter designs.

Design Optimization Of Active-Stabilizing Canards For High-Powered Rockets, Simon Babcock

Senior Honors Theses

Rocket canards are a common means of stabilizing a high-powered rocket in flight by producing aerodynamic forces to correct the rocket's trajectory. The size, shape, and position of the canards relative to the rocket body determine their control effectiveness and aerodynamic efficiency – two objectives of canard design with an inverse relationship to each other. By integrating automated iterative rocket trajectory simulation with adaptive surrogate modelling, this research optimized the canard planform geometry for a high-powered rocket to maximize the canards’ control effectiveness and aerodynamic efficiency through multi-variable, multi-objective design optimization.

Stabilized Cargo Relay Aircraft For Precision Payload Yielding, Dato A. Tabidze, Michael Conely, Ben Courtney

Senior Design Project For Engineers

As military missions become more complicated, warfighters need more capable drones to use across diverse scenarios. The same also applies to civilian applications, like infrastructure inspection, package delivery, and disaster response. Current multirotor drones, also known as unmanned aircraft systems (UAS), provide simplicity, affordability, and ease of operation; however, their primary limitation is their low payload-to-weight ratio, which typically falls at 1:1 or less. The DARPA Lift Challenge aims to shatter the heavy lift bottleneck, seeking novel drone designs that can carry payloads more than four times their weight, which would revolutionize the way we use drones across all sectors. …

Numerical Investigation Of Rotor-Gust Acoustic Interactions Using The Overflow Cfd Solver, Jordan Mills

Doctoral Dissertations and Master's Theses

The rapid expansion of Urban Air Mobility (UAM) necessitates high-fidelity modeling to predict and mitigate the noise signatures of electric vertical take-off and landing (eVTOL) aircraft within dense urban landscapes. A critical unknown in community-noise certification is the aeroacoustic response of rotors to unsteady inflow conditions. This research addresses this gap by investigating the aerodynamic and acoustic behavior of a representative rotor subjected to time-harmonic inflow disturbances. By establishing a robust numerical framework, this thesis quantifies the relationship between periodic atmospheric gusts and their impact on rotor performance, unsteady blade loading, and subsequent sound radiation. The research consists of a …

Effect Of Nozzle Pressure Ratio On Thrust And Flow Behavior In A Supersonic De Laval Nozzle, Esha Jain

Doctoral Dissertations and Master's Theses

Supersonic nozzles operate across a range of flow regimes. While an ideally expanded condition yields optimal thrust, practical propulsion systems rarely operate at this design point due to variations in altitude and engine operating conditions. As a result, nozzles frequently operate in off-design conditions. In overexpanded regime, where the exit pressure is lower than the ambient pressure, shock-induced separation may occur within the divergent section of the nozzle, potentially degrading nozzle performance. Understanding the aerodynamic behavior of nozzles operating under off-design conditions is therefore important for improving propulsion system performance and stability. In particular, direct thrust measurements provide a key …

Autonomous Uav Mission Planning Under Threat Using Model Predictive Control With Proportional-Navigation Pursuers, Mehmet B. Ozcelik

Mechanical and Aerospace Engineering Theses

Autonomous unmanned aerial vehicles (UAVs) operating in contested environments must

complete mission objectives while avoiding restricted regions, radar exposure, and pos-

sible interception. This thesis develops a MATLAB-based simulation framework for

two-dimensional UAV mission planning under threat using model predictive control and

proportional-navigation chasers. The mission requires the UAV to travel from a start

location to a goal while visiting required checkpoints and avoiding no-fly zones and radar

regions. A chaser attempts to intercept the UAV using either a basic pure-pursuit-style

law or a proportional-navigation guidance law.

The framework integrates environment generation, augmented visibility-graph rout-

ing, waypoint management, UAV kinematic …
