Notas do Editor
- Artist rendering of the CEV in space.
- Artist rendering of the complete launch vehicle with the CEV attached to top, just below the abort rocket motors.
- 2000 to Present with progressively more difficult projects starting with the most recent.
- The first Chariot stand-on riding floor scrubber . Responsible for internal design of sheet metal parts, welded assemblies and plastic surfaces, to achieve desired functionality.
- Completed model. (Colors are for ease of visibility only) Created key external components from Industrial designers imported file (ICEM).
- Views of rotational molded tank showing internal surface detail required for machine functions.
- Additional view of tank details.
- Chariot lower frame: Designed modular welded sheet-metal component & sub-assemblies. Weight is transferred from the center front drive unit, down the middle channel about mid-way, then spread laterally down the sides to the rear wheels
- Upper frame: Sheet-metal sub-assemblies, also modular, support upper body of operator and controls.
- Electrical housing (Rotational molded) & sheet metal control panel attached to upper frame section.
- Vacuum formed bumper assembly provides flexible protection to customers facility.
- Rear cover attaches over the rear axle & back of control panel. Tilts back or can be removed completely to access batteries.
- Developed original layout for swinging squeegee: Linkage pivots around the center shaft of the front drive unit to allow nearly 100% pick-up of water on 90 degree turn.
- Steering components for front drive unit. Designed brackets & shafts for maximum adjustability. Sourced chain & sprockets to achieve 3 to 1 steering ratio from lock to lock.
- Tank with internal bag (bladder) system. Bag designed in sheet metal module to allow it to be cut from a single piece of material then seam welded together.
- Vacuum installation & seals. Rear surface of rotational molded tank allows exhaust from vacuum motors to dissipate downward through the body of the machine.
- Chariot Burnisher for which I did the original functional development work.
- Compact 17 inch scrubber cost reduction & improved squeegee. Total cost was reduced by 50% . Squeegee performance improved by more than 50%.
- Screenshot of completed model with squeegee.
- Improved squeegee assembly (top view) showing transition (in blue) which allowed more freedom of movement without sacrificing any performance.
- Bottom view showing stainless steel inserts (dark gray) on both sides of center opening providing additional weight to the otherwise lightweight aluminum assembly.
- Cross section showing smooth transition from intake (gray portion above thin squeegee blades) to hose end of transition piece.
- Cutter walk behind scrubber.
- Cutter rotational molded tanks & front cover showing details of internal surfaces & ribs for rigidity.
- Cutter front & rear views.
- Glide sit-down riding scrubber. I helped release most of the final drawings for production.
- Compass multi surface machine, able to inject chemicals & recover them as well. I helped with releasing final drawings.
- Required to improve function of this floating side squeegee for previous generation ride-on scrubber. Inset shows old design.
- Redesigned fan housing with integral cord-wrap & wheeled handle.
- Designed Engine Stands and Cradles for the Boeing 777 engines, as well as Tow bars, and some hydraulic tubing. 1992 to 2000 liaison between engineering & production personnel
- Completed Engine Stand/Cradle with Boeing 777 engine attached.
- Completed shipping pallet for Boeing 777 engine attached to cradle.
- Completed engine stand for Rolls Royce engine for Boeing 777.
- Typical welded aircraft towbars.
- Typical stainless steel and aluminum welded tubing.
- Plasma seam welding machine in operation. This machine is capable of welding 5/8” aluminum at 100% penetration in a single pass.
- Internal view of completed plasma weld.
- External view of completed plasma weld.
- Helium and ultrasonic testing of plasmawelds.
- Typical weld quality.
