Advanced Dynamics of Aerospace System
- Vector dynamics of aerospace system, three dimensional particle and rigid body dynamics, linear and angular momentum, method of Euler, Lagrangian dynamics, and a basic understanding to space vehicle motion.
Finite Element Structures
-Theoretical development of one and two dimensional finite elements. Analysis and design of truss, frame and semimonocoque structures using computer aided software, (NASTRAN), and analysis with commercial finite element software.
PROJECTS:
ECLSS & Vehicle State of Health: Researched and developed a conceptual environmental control and life support system for a reusable Earth-To-Orbit commercial space vehicle. Design a complete pressurized closed loop forced air filtration system for 24 passengers with crew for a 6hr mission with 24hr contingence. Cabin is design as a pressure vessel with structural stability to with stand 24 psi. Presented final results to a panel of judges at Jet Propulsion Laboratory in Pasadena, CA for review
Vertical Lifting Circular Wing Project: Part of a team to research and develop the feasibility of a vertical lifting body using a patented circular wing design, Designed a duct system to translate vertical airflow to a horizontal direction in order to create wing lift, Constructed a duct and wing from a Solidworks model with fiber glass to insure strength and to minimized weight.
Concept of a X-48 with SOL and Endurance Configuration Project: Design a conceptual aircraft fuel system with a team utilizing a system architecture software, Core 7, to plan, organize project requirements, tied connections of higher and lower subsystem and run simulations for instance to see how long it would take to fire up the engines or to see if certain criteria would be carried out based on certain probability factors
Stability and Control Analysis Project: Designed a code using MATLAB and Simulink to analyze the stability and control configuration of a Beech 99 aircraft
Flight Simulation and Propulsion Simulation Project: Calculated the flight characteristics and propulsion capabilities of a Learjet 45 using Microsoft Excel
