Integrated Defense Systems

MMIII Guidance Replacement Program – March 1994 to January 2004

~ Lead Mechanical Design - Missile Guidance System Control Assembly and Prototype Radiation Shielding.

Managed mechanical design of system electronic assembly and components from proposal through release of

production drawings. Retained nine years of experience with developing investment castings utilizing aluminum

A357 material and integral stainless steel tubing. Defined customer requirements and investigated alternative designs

for prototype assemblies of the electronic system and radiation shielding. Identified costs of mechanical hardware,

created schedules to achieve program objectives, and prepared reports for management and customer acceptance.

Participated in developing design concepts for new guidance systems. Initiated and completed mechanical testing to

certify compliance for flight. Applied CATIA V5 and I-DEAS Solid Modeling techniques to optimize design of

mechanical hardware and documented release of drawings with ASME Y14.5, GD&T and eMATRIX Product Data

Management.

Research and Development - June 1990 to March 1994

Guidance Positioning Systems - Digital Quartz Inertial Measuring Unit

~ Conducted field experimentation to weld aluminum chassis containing assembled electronic guidance systems for

applications within high vacuum environments. Developed a schedule to effect structural and hermetic welds within

the aluminum housings with LASER energy as a heat source.

Reentry Body Inertial Measuring Unit

~ Supported proposal activities with design and testing an isolated platform to stabilize electrical components for

guidance and control. Prepared the mechanical section of the proposal to include features for design and packaging

of the electrical system and results obtained from testing the prototype isolated platform when subjected to

environments of vibration and shock.

Space Based Cryocooler

~ Created a prototype mechanical assembly to isolate a cryocooler when subjected to environments with variations in

vibration, shock, and temperature. Manufactured tooling to support testing of this prototype assembly.

Brilliant Pebble Deployment Concept

~ Supported proposal activities with the design of a gunrail delivery system for ejecting Brilliant Pebbles from an

Atlas IIAS launch vehicle

Small ICBM Program - Thermal Engineering

~ Simulated behavior of a thermal cooling system with finite difference programming techniques. Predicted

performance of a vapor-compression cycle with refrigerant R-12 as a working fluid. Participated in the design of

cooling system components.
