Boeing, Structural Design Engineer 2 – Mesa, AZ Jul 2017 – Present

Developed airframe design solutions for the AH-64E Apache Helicopter using NX. Created 50 fully parameterized 3D CAD models for machined, sheet metal, and composite components of the wing, stabilator, engine nacelle, and fuselage.

Produced 25 conceptual designs to support the rapid integration of new tactical avionics systems. Designed aerodynamic fairings and supporting structures to ensure compliance with static and dynamic load requirements. Collaborated with stress, aerodynamics, electrical, and manufacturing groups to conduct design reviews and qualify initial design concepts.

Designed new parts using DFMA and GD&T to improve producibility, maintain first-time quality, and reduce labor costs.

Processed 35 change orders to manage product definition, support production, and address supplier information requests. RPI Scientific Computation Research Center, Graduate Research Assistant – Troy, NY Aug 2016 – May 2017

Conducted computational fluid dynamics (CFD) simulations to analyze and fine-tune a new turbulence model for large eddy simulation (LES). Implemented the model in PHASTA, a Fortran-based finite element analysis (FEA) solver.

Modeled geometry using NX, generated meshes, set boundary conditions, ran simulations, and post-processed results for over 15 test cases for initial testing and concept validation. Test cases consisted of laminar and turbulent channel flow.

Simulated the external flow field around bluff bodies to induce vortex shedding cycles. Demonstrated the new turbulence model’s superior ability in resolving and visualizing time-dependent advection, diffusion, and fine-scale velocity fields. Sikorsky Aircraft, Aerodynamics Intern – Stratford, CT May 2016 – Aug 2016

Conducted aerodynamic analyses on various Black Hawk mission profile configurations in order to determine critical performance attributes such as loiter time, hover ceiling, max take-off gross weight, fuel burn, climb, endurance, and range.

Simulated ice accretion on the Maritime Helicopter in high-speed forward flight to develop a safe flight envelope by calibrating simulation inputs to match flight test data. Analyzed stability and control, blade flapping, and stall speeds.

Computed 350 aircraft performance predictions using numerical computation tools and analytical hand calculations to determine the drag impact of external design modifications for the CH-53K USMC Heavy-Lift Helicopter and the S-92. RPI Bio-Optofluidics Laboratory, Undergraduate Research Assistant – Troy, NY Sep 2015 – Dec 2015

Designed a microscope mounting frame rotating attachment in SolidWorks to reduce microfluidic experiment run-time by 10%. Generated 3D printed prototypes and performed tolerance stack-up analyses to ensure proper fit of components. FirstLight Fiber, Engineering Intern – Albany, NY Jun 2015 – Aug 2015

Created the company’s first fiber-optic network map of 200 circuits using GIS software. Developed Excel Visual Basic macros to automatically format and organize hundreds of electronic databases. Completed project 25% ahead of schedule. PROJECT AND LEADERSHIP EXPERIENCE

Box-Wing Aerodynamics Simulation, CFD Analyst – Troy, NY Jan 2016 – May 2016

Conducted CFD simulations on a 3D box-wing configuration to analyze the wingtip vortices of a closed wing design. Ran simulations using ANSYS, showing that the box-wing experiences lowered induced drag compared to conventional wings. Compound Helicopter Capstone Design Project, Project Lead – Troy, NY Jan 2016 – May 2016

Led a team of three in using MATLAB to analyze the high-speed forward flight performance and rotor dynamics of a compound helicopter, based off the Black Hawk integrated with fixed wings and an auxiliary propulsor. Performed a parametric sweep of redundant controls in order to determine minimum power requirements for stable forward flight. Wind Tunnel Experiment Design, Wind Tunnel Experimentalist – Troy, NY Sep 2015 – Dec 2015

Designed and conducted subsonic wind tunnel tests to study the aerodynamic characteristics of airfoils, bluff bodies, and vehicles. Analyzed fluid dynamics data, organized results in a technical report, and presented findings to lead researchers. EDUCATION
