📖 Summary

Senior Professional Staff I @ • Independent Research and Development Project (2013-Present) Development and Design of new Multi-Stage Underwater-Launched Ballistic Missile Concept Aided in creation and debugging the IRCPGS Simulink 6-DOF model Supported addition of Monte Carlo Capability within 6-DOF Designed and Implemented PID controller in support of analysis of vehicle stability and environment sensitivities during staging event Utilized the program "Optimal Trajectories by Implicit Simulation" (OTIS) to analyze various vehicle design considerations • Trident II (2013-Present) Initiated and lead development of Simulink based 6-DOF of legacy simulation, which will ultimately lead to greater modeling capability and analysis Work with junior engineer and responsible for demonstrating ‘best coding practices’ and maturing their technical development Responsible for validation and verification of 6-DOF models, scheduling and tasking • Integrated Nose Fairing Study (2014) Study to determine pro/cons of various nose fairing concepts that could potentially integrate with the closure of a submarine’s missile tube Missile Lead for Nose Fairing activity, responsibilities included:  Coordinated and Scheduled various analyses among a team of 10 engineers to understand thermal, range, structural, aerodynamic, and mass impact of numerous concepts  Compiled findings from studies in an efficient way to effectively utilize study results and apply to numerous concepts, minimizing the need for repetitive analysis From February 2013 to Present (2 years 11 months) Systems Engineer Sr. @ Guidance, Navigation, and Controls (GNC) Infra-red Search and Track (IRST F-18) Developed and designed Sensor Manager algorithm, its function was to determine the scan pattern and volume based on the user-defined search mode, reject tracks located within aircraft mask, correlate IRST tracks with A/C tracks and determine target priority. Created MatLab simulation to test and debug algorithm. Joint Strike Fighter (JSF) Aided with analysis and debugging of Navigation Kalman Filter developed in the Simulink Environment Created scripts to run Monte Carlo dispersion study on MatLab cluster, to aid in Kalman Filter tuning Created numerous analysis and plotting scripts to aid in debug and analysis of navigation algorithm Independent Research and Development Project Guided Projectile Developed MatLab based three-degrees-of-freedom (3-DOF) model from "scratch" Used for Max L/D and Augmented Proportional Navigation guidance law development and preliminary trade studies Responsible for C++ based six-degrees-of-freedom (6-DOF) model creation and Guidance and Controls algorithm development Quick development of 6-DOF model found that a vehicle redesign necessary to fly a successful mission, timeliness of discovery prevented a major setback in schedule Formal training courses: Modern Missile Autopilot Design Aerodynamic Fundamentals From January 2009 to January 2013 (4 years 1 month) Orlando, Florida AreaGNC Engineer III @ Aided in creating and debugging numerous 6-DOF models for various vehicle (many for proposal work) based in the Simulink environment. Vehicles include: Multi-Stage Rockets, Hypersonic Vehicles, and High Frequency (>15 Hz) Spinning Body frames Vehicles feature: Canard Control, Thrust Vector Control, Scramjet, Attitude Control System (ACS), Throttle Thrust Control Utilized 6-DOF expertise and vehicle familiarity to determine cause of ALV-X1 mission failure. Designed Waypoint Guidance Algorithm for multi-stage vehicle Performed Linear Analysis and 'Gain-Scheduling' for roll channel ACS system, which reduced ACS gas consumption by a factor of 3 Using MatLab Real-Time Workshop, auto-coded GNC algorithms designed within Simulink environment into a C language counterpart. This process greatly reduced the time needed to setup Hardware in the Loop (HIL) tests, and helped validate our GNC algorithm by porting it into more established 3rd-party 6 DOF models such as NASA's Program to Optimize Simulated Trajectories (POST) FORTRAN based model. Using C++ based 6-DOF; integrated, debugged, and tested embedded code GNC algorithms involving Digital Terrain Elevation Data (DTED) and Geospecificity data Support lab HIL/ ARH chamber simulation implementation and execution, data playback, GPS RF simulator, F-18 command launch computer (CLC) simulator Created post data analysis tools in Matlab for data reduction of Telemetry Data collected from HIL and test flights.
