- 7. Project Assignment & Result Task 1. Obsolescence - Rounds Limit Switches (RLS) Evaluated current specification drawings and existing designs to improve material selections and developed Pro-E designs for assembly build-to-print drawings to meet environmental and the part performance requirements for Warner Robins Air Logistics Command. Performed product qualification by analysis and verification by cycle test and fire test. Designed new mechanical 5 rounds reverse clearing hysteresis for A-10 RLS. Also, completed new designs for F-16 and F-15 aircraft.
- 8. Project Assignment & Result Task 2. Specification of Servo System Components Evaluated mechanical dynamic loads of ammunition handling control systems to determine effects of system inertia and acceleration & speed requirements to meet time lines for the test case scenarios. Optimized servo motor performance for size and weight. Performance met gun firing timeline on the Crusader Self-propelled Howitzer and the ammo field supply mission of the Resupply Vehicle. Also, designed custom brakes and clutches for x-y-x ammunition supply shuttles and custom transmitter and receiver optical sensor pair to determine the ammo position on the conveyors.
- 9. Project Assignment & Result Task 3. JSF Aircraft Cables for Lockheed Martin Designed aircraft military interface cables to meet customer requirements for light-weight construction materials while meeting the high temperature specs, the functional electrical system performance, and the EMI test requirements. Cables met EMI under electrical system loads. Also, designed other dynamic cables (based on my own method for isolating the cable components to allow independent movement) for the JSF 20mm Gatling guns to meet rigors of gun firing and recoil.
- 10. Project Assignment & Result Task 4. Create EFV Software Test Plan & Test Cases Based on EFV turret system specifications for ammo handling system, developed the software test plan and test cases for the embedded control unit firmware to meet system level and derived requirements.Validated the bench-top system performance using servo motor loads. System improvements made in incremental releases. Part of electrical project team that developed the electronic digital control unit, firmware, motors, cables, and test equipment for ammo feed system. The embedded control unit worked successfully on the EFV.
- 11. Project Assignment & Result Task 5. Debugged and Repaired Test Equipment Performed troubleshooting on inoperable CIWS production test panel that was severely damaged during transportation. Rebuilt cables and also ruggedized the design.Verified signal timing functionality with a digital storage scope. Performed validation to QC Acceptance Procedures. The test panel was returned for production verification of CIWS circuit cards. Also debugged AV-8B test set, with its case severely damaged from years of field use. Specified and quoted parts BOM for repairs. Performed validation to QC Acceptance Procedures.
