RELATED EXPERIENCE

Mechanical Design Engineer

EMB550, Flap Surface Actuation

Parker Aerospace, Irvine, CA

Sep. 2008 - July 2009

Designed electro-mechanical flap actuation components, actuator, structure

and failsafe brake. Flap actuator installation, structure interface and

layout. Defined actuator location on the wing structure evaluating load

paths, clearance to structure, clearance to skin and fluid lines.

F-35 JSF, Flight Test

Northrop Grumman, El Segundo, CA

Apr. 2007 - Oct. 2007

Prepared transducer installations for JSF flight test, layout models, sheet

metal design and electrical routing. Completed installation drawings build

packages.

X-47B, Landing Gear Doors

Northrop Grumman, El Segundo, CA

Jan. 2006 - Apr. 2007

Main landing gear door mechanism design including structural fittings,

actuator specification, envelope definition, assembly layout, detail part

design, mechanism design, kinematics analysis, up-lock integration, detail

build-to packages, assembly and component level GD&T, sensor integration

and CDR slides preparation.

F-16, Bomb Rack

Sargent Fletcher Inc., El Monte, CA

Nov. 2004 - Nov. 2005

Performed F-16 pneumatic bomb rack design for production, including high-

pressure gas sealing redesign, piston & cylinder with staging, forgings,

hook and latch mechanism. Generated production level assembly prints, Bill

of Material and assembly instructions. Completed GD&T review of all

assembly components. F-35 JDAM weapons bay bomb rack conceptual design and

layout, rack detail, store layout, clearance volumes review.

F-35 JSF

Applied Int. Motion, La Verne, CA

Dec. 2002 - Oct. 2004

Lead design team through concept evaluation, design, fabrication, testing

and assembly of 6-axis CNC. Designed precision linear and rotary drives,

feedback, alignment mechanisms, fluid delivery, cable and hose routing,

clamping and lockdown mechanisms, sensor integration, manifolds, connector

bulkheads, machine structures, assembly jigs including FEA analysis.

Structures were designed to maximize machine stiffness. Performed hand

calculations and FEA to maximize structure stiffness. Evaluated

structures for thermal stability to maximize precision and repeatability.

F-22

Mar. 2001 - Nov. 2002

Lead design team through concept evaluation, design, fabrication, testing

and assembly of 6-axis CNC. Designed twin gantry automated drilling

machine. Completed structures and assembly jig design, supervised part

inspections, installation and alignment. Generated acceptance and service

documentation. Conducted machine performance testing, data analysis and

reporting.

F-18

May 1999 - Mar. 2001

Lead design team through concept evaluation, design, fabrication, testing

and assembly of 6-axis CNC. Simulated work envelopes, travels and part

access for 6-axis CNC. Designed precision drives, mechanisms, precision

weldments, hydraulic and pneumatic actuation. Developed new spindle and

drill unit design.

F-18

Jan. 1997 - May 1999

Simulated work envelopes, travels and part access for 6-axis CNC.

Conducted design review and progress report meetings.
