Design Build Fly: University of Oklahoma Team Crimson Skies 2020-2021 Team CAD Lead

• Nominated and elected by 25 of my peers to be the Team’s CAD Lead

• Acted as the link of communication between the 3 sub-teams and all 25 members

• Translated all concepts and ideas into SolidWorks designs accounting for size and weight limitations

• Responsible for manufacturing plans/processes for each individual component and system

• Continually update the aircraft’s design through each stage of designing, building, and testing Projects

F35A Turbofan Performance Analysis October 2020

• Show through mathematical analysis that the engine’s non-ideal performance envelope was compatible with the aircraft’s aerodynamic characteristics o Performed a detailed analysis on a turbofan engine by utilizing and applying a deep understanding of the theory for turbine-based propulsion systems o Utilized the basic known information of the turbofan engine, such as inlet and exit diameter, and the turbine inlet temperature and fan pressure ratio to calculate the operational conditions present at every stage in the engine

• Determined compatibility by verifying:

o The aerodynamic requirements needed for the F35A to takeoff and comparing the engine’s sea- level thrust production

o That the engine was at its most efficient while the aircraft was at its known cruise altitude and velocity

o Analytically show that the maximum possible range occurred while the aircraft was at its known cruise altitude and velocity

B52 Replacement Design and Analysis April 2020

• Worked in a group of 2 with the challenge to design a bomber aircraft with a combat radius of 5,000 nautical miles

o Designed the aircraft from scratch with all aerodynamic and weight sizing verified through numeric analysis

o Validated the aircraft to be statically and dynamically stable through both numerical analysis and software such as MATLAB and XFLR5

• Created the aircraft in XPlane11 via its Plane-Builder function and flown to verify the takeoff and flight characteristics

• Obtained in-flight data by outputting the simulator’s computational aerodynamic model to determine how the aircraft would perform given its unique aerodynamic characteristics

• Compiled and analyzed the resulting data to compare the similarities between the numerical analysis and simulated characteristics

Expected Graduation Date: May 2021

Overall GPA: 3.13

Wing Structural Design and Analysis April 2020

• Design and create the lightest possible wing structure for given loading o Specified limitations for wing bending, flexure, and Factor of Safety o Structure must be completely contained inside a given wing outer molding skin

• Required creative thinking to balance the relationship between weight and Factor of Safety

• Sizing and hand calculations were verified through Solidworks FEA capabilities

• Performed studies and analyzed how to properly configure and use FEA software Wind Tunnel Analysis of a Scaled F35 Model December 2019

• Determine the correction factors required for OU’s Closed-Loop Wind Tunnel o Accomplished by repeated testing and calibrations for each instrument

• Worked in a group of 5 to determine the aerodynamic characteristics of a scaled F35A model

• Compiled raw data from the Wind Tunnel after performing a variety of tests on the F35A model

• Data was corrected and analyzed to determine what a full-sized aircraft required to maintain flight

• Analysis was compared to the known characteristics of the F35A to validate testing procedure and all results were reported and presented to our peers

First Robotics August 2012- February 2013

• Worked in a team of 20 to design and build a robot which could: o Pick frisbees off the ground and launch them through a narrow slot on a wall 30 feet away o Capable of climbing a steel pyramid at the center of the arena

• Led a group of 5 to design, build, and test the electro-mechanical system that would pick the frisbees off the ground, elevate them, and precisely launch them across the arena

• Contributed to building nearly every part of the robot; main structure, launching mech, pick up mech

• Chosen by the team to be 1 of the 2 people allowed to touch the robot during competition; troubleshoot, diagnose problems, and repair it in very little time First Robotics August 2011- February 2012

• Worked in a team of 23 to design and build a robot which could: o Pick foam basket balls off the ground and launch them into a basketball hoop around 30 feet away

o Interact with and balance on top of a seesaw bridge at the center of the arena.

• I was part of a group of 4 that designed, analyzed, and tested the mechanism that would pick up the basketball and launch it

• Chosen by the team to be 1 of the 2 people allowed to touch the robot during competition; troubleshoot, diagnose problem, and repair it in very little time Work History
