Work Experience

Independent Contractor

Madison, WI

2014 to 2014

Spaceflight Mechanical Engineer – Environmental Controls & Life Support Systems (ECLSS); Humidity Control System 
-Employed as a Lead Design Project Engineer for the U.S. Human Spaceflight initiative of NASA’s Commercial Crew Program (CCiCAP – Commercial Crew Integrated Capability phase) for the development of the SNC Dream Chaser winged space-plane. This phase of the development involved a head-to-head competition between the SNC Dream Chaser, the Boeing CST-100, and the SpaceX Dragon as three commercial space-ships for U.S. human transport capability to the International Space Station (ISS). The first step of the job was to understand the Concept of Operations (CONOPs) of the SNC Dream Chaser from its Launch Phase (aboard an Atlas V rocket), to its Abort Modes during the ascent into space, to its In-Space flight/Rendezvous/Docking with the ISS, to its Departure Mode from the ISS, and to its Re-entry through the atmosphere, Lifting Body Flight, & Terrestrial Landing stages. The second step of the job was to learn how the Dream Chaser compared to meeting NASA’s Human Spaceflight requirements via the earlier legacy Mercury, Gemini, Apollo, and Space Shuttle Programs and the existing ROSKOSMOS (Russian Space Agency) Soyuz Spaceship Program as it is launched aboard a Soyuz Rocket from the Baikonur Cosmodrome site in Tyuratam, Kazakhstan. The third step of the job was to delve into the role of developing the Moisture Removal Package for the Humidity Control System; SolidWorks 2012 was utilized for 3-D Solid CAD Models, Visio was for 2-D drawings, & MS Windows 2007 was the office suite: 
--Pressure Regulator studies for the Oxygen and Nitrox (80% Nitrogen & 20% Oxygen) delivery systems. 
o This was the part of the Air Revitalization System (ARS) that metered air aboard the spaceship and involved: 
- Dynamics Analysis of the hardware via the Power Spectral Density profile projected during flight. 
- Measurement and 3-D solid modeling of the prototype hardware. 
- Development of space-flight worthy leak testing techniques. 
--Fan Blower Motor Controller development of the ARS.  
o This was the Pulse Width Modulated 3-phase control of the 28V Brushless DC fan motor that involved: 
- Developing a board outline and Circuit Control Assembly package that contained the Motor Controller power supply, 
DC-to-DC Converter, Power MOSFET, Choke Coil, internal and external electrical connectors, Printed Wire Board layout, 
and a lumped capacitance transient and steady-state thermal analysis to assess the semiconductor junction temperatures. 
- Incorporation of radiation-tolerant Hall Effect Sensors for fan motors in the spaceflight ionizing radiation environment. 
-Development of Fan-Speed Curve Test Techniques to understand the fan performance. Reliability studies. 
--Humidity Removal Package (HRP) development of the ARS.  
o This was the human metabolic moisture removal technique for the Dream Chaser cabin that involved: 
- System Modeling of the DuPont Nafion® semi-permeable tubing that was purchased from Perma Pure LLC. 
- Development of test techniques for the measurement of Moisture Removal versus Air Flow for various designs 
of the Nafion® Bundle geometries within a simulated cabin environment at the company’s Greenview Test Site. 
- Assessment of the test data for iterative design of the Nafion® Bundle geometries within a vacuum-containment system. 
- System design/analysis integration of the HRP into several preliminary layouts of the ARS in the Dream Chaser spaceship.

AAR CORPORATION; AIRLIFT GROUP [Contract w/Aerotek Aviation - Orlando FL]
Melbourne, FL

2012 to 2013

Aircraft Structural Engineer; FAA FAR Part 145 Repair Station & Part 135 Charter Service 
-Provided the design engineering and detailing support for structurally implementing avionics modifications and system upgrades into the AAR Airlift Group's fleet of aircraft logistics operations with U.S. military, NATO, and U.N. expeditionary missions. This fleet was notably comprised of the fixed wing CASA C-212-200 (CC/CD Models) and CASA C-212-300 (DF Model) STOL (Short Take-off & Landing) & Bombardier DeHavilland DHC-8-103 (Dash-8) transport airplane assets along with the rotary wing BELL 412 & Aerospatiale EUROCOPTER PUMA SA330J models of helicopter assets, amongst other fixed/rotary wing aircraft. 
-Designed a unique Portable Oxygen System for the 30/29/21 seat passenger compartment configurations of the Dash-8 aircraft. Based on travelling out for mapping surveys of an aircraft during Heavy Check maintenance at AAR's Oklahoma City OK facility, an installation technique was designed by 3-D CAD system, followed by an FAA DER (Designated Engineering Representative) structural substantiation of the incipient drawings, prior to its sanctioned implementation. This FAA-approved design enabled passenger-carrying flight routes over mountainous terrain (above 12,500 feet altitude) in the event of cabin depressurization. 
-Reverse-engineered a Closed Circuit Refueling (CCR) system for pressurized hovering fueling of the PUMA SA330J aircraft. This effort was in support of developing a Supplemental Type Certificate (STC) for this relatively quick means of replenishment that enabled these Military Sealift Command shipboard-based helicopters to provide for the logistics needs of naval fleet elements..
