Engineering contract involved stress report analysis and corrective actions regarding aircraft installations or modifications for primary and secondary structures. Engineering corrective actions for installation errors such as fastener counts, edge distance, hole oversize, for rivet or hy-lok fasteners. Hand calculations was most often used for installation modifications, or payloads. G-force inertial load analysis for payload and equipment installations with backed up documentation. Signature authority for approving (sign off) or disapproving other engineer's corrective action documentation from the Stress Engineers point of view ensuring aircraft structural integrity. As a contractor, was available all hours without any missed days. Utilized onsite software such as SolidWorks and office products.

Engineering analysis on Boeing 787 fuselage manufacturing efforts in Vought’s South Carolina production facilities. MRB work was done for aircraft production efforts. Provided installers with engineering data and corrective actions for aircraft manufacturing production. Redlining of mismatched parts during fuselage assembly. Developed repairs for composite and titanium structure during 787 production as corrective actions. Assisted in fuselage production efforts in many capacities to ensure production schedules are being met. Utilized IVT and other Boeing software programs associated with aircraft production. Strong familiarity with composite and titanium structures and how to best utilize such materials for aircraft production. Software tools utilized were CatiaV5, Enovia, Ansys, Nastran/Patran.

Stress Analyst position. Utilized Ansys stress analysis software to analyze lighting systems to be installed on many types of aircraft. F22 light systems were analyzed. Acceleration and vibration loads were applied to a light assembly to determine deformation, load limits, factor of safety, stress, and strain. Load and vibration analysis models were developed on light assemblies. Material properties were determined. Engineering data was inputted into Ansys load model to evaluate stress in parts of assembly. Design changes were recommended for light assemblies that did not meet stress analysis standards. CatiaV5 used for assembly.

Stress Analyst/Design Engineer capacity. Utilized CatiaV5 software on repair design work for Boeing commercial 787 composite and titanium structured aircraft. Designed numerous composite and titanium repair methods to be used at aircraft repair sites on primary and secondary structures. Repair sizing and loads analysis. Repair design concepts are to be used when certified in standard structural repair manuals. Structural analysis of the repair concepts for certification purposes. Strength calculations on critical components. Material properties. Nastran/Patran, Ansys, hand calculations, load models. Fatigue calculations. CatiaV5 solid modeling. Experience with both composite and titanium structure.

Stress Analyst capacity. Did Stress Analysis and structural engineering work on the UH-60 and UH-47 helicopters at Bluegrass station (U.S. army base) in Lexington, KY. Involved in doing stress reports on modifications to helicopter primary and secondary structures. Loads analysis on equipment installs. Crash load analysis and structural design. Analysis work for engine mounts on helicopters for higher output engine replacements. Design, qualification, manufacture, repair, overhaul of landing gears and flight components on helicopters. CatiaV5, Ansys, Nastran/Patran.

Structural Design Analysis capacity. Conducted Stress Analysis and structural engineering work on the UH-60 helicopters at Redstone Arsenal (U.S. army base) in Huntsville, AL. Involved with flight testing exceedance analysis, structural modifications, structural analysis, turbine engines, and equipment. Qualification of loads (crash) specifications. Critical component strength calculations of primary structure. Landing gear analysis, loads, margins, material strength, fatigue. Nastran/Patran, Ansys, CatiaV5.

Structural Design and Analysis capacity. Aging aircraft analysis, primary or secondary structure repair/analysis, designing repairs for structural cracks resulting from stress corrosion, finding or making tooling needed to fabricate replacement components, utilization of CNC machining techniques to accurately fabricate replacement components to exact drawing specifications, replacing mechanical & hydraulic components when necessary, and maintaining information on repair status of aircraft. Design, qualification, manufacture, repair, overhaul of flight critical components. Strength calculations on landing gear components. Sizing and loads analysis on structural repairs. Technical manual revisions, creating repair procedures, making technical drawing revisions. C-5 aircraft is the craft I did most work on.

Designed hydraulic manifolds used for aircraft and industrial applications. I designed each manifold from startup to completion. Determined raw material of manifold and wall thickness of internally machined out hydraulic passages. Produced engineering drawing of manifold to be fabricated by machine shop. Selected hydraulic directional and pressure controllers like high flow rate directional control valves, pressure relief devices, shutoff valves, pressure measuring connectors to comply with hydraulic schematic. Under engineer's direction, machine shop personnel fabricated manifold then assembled the end product which was pressure tested at maximum burst pressure determined by engineer. Manifold assembly is then integrated into a hydraulic drive system out in the field used for controlling and hoisting functions.

Worked as a Mechanical/Structural engineer for McDonnell Douglas Space Systems Division on the Kennedy Space Center in Florida. Experience includes the design and modification of various mechanical components, facility structures, ground support equipment, space shuttle & payload structural modifications, valve & gage panels, piping & hydraulic systems, electrical & electronic equipment, clean room environmental systems, containers used for the transport of gases or fuels, etc. which are utilized at various existing installations on the Kennedy Space Center for satellite, rocket, and space shuttle processing facilities.
