20. Goddard Lift Kitfor the Piper Supercub This client developed and built a lift kit for the Piper Supercub and Piper Pawnee. These kits are installed on the rear of the wings increasing their lift and lowering their stall speed. They constructed the prototypes with preliminary sketches and through trial and error. I was hired to reverse engineer these two prototypes and two additional ones that were gap seal kits also for the same planes. The gap seals are designed to improve the aerodynamics of the wings by sealing the gap between the wing and the aileron. For all four products I created the fabrication, installation, and patent drawings. The following examples were selected from the Piper Supercub lift kit fabrication and installation drawing packages plus the Patent drawings. All solids models were created as individual components which allowed more flexibility in utilization. AIRBORNE RESEARCH Client: Created with AutoCAD 2000i

21. Fabrication drawing - Lift kit mounting bracket assembliesAll details are created using the 3D model. AIRBORNE RESEARCH Client:

22. Fabrication drawing - Bracket plate detailsThese details were created in 2D because of AutoCAD’s limited model dimensioning capabilities in this version. The 2D graphics were used to extrude 3D parts though. AIRBORNE RESEARCH Client:

23. Fabrication drawing – Air foil front attachment bracket detail.As with the prior drawing these details were created in 2D AIRBORNE RESEARCH Client:

24. Fabrication drawing – Aileron bay bracket detailsThese details were from the 3D model. AIRBORNE RESEARCH Client:

25. Fabrication drawing – Attachment strap detailsThese details were 3D modeled for clarity. AIRBORNE RESEARCH Client:

26. Installation drawing 1 of 4 – Installation locationsThe following 4 drawings are issued with the kit to be used by the FFA certified technician installing it. The plane was created in 2D because only one view was required to show the installation locations. AIRBORNE RESEARCH Client:

27. Installation drawing 2 of 4All details on this drawing were assembled from the individually modeled components. AIRBORNE RESEARCH Client:

28. Installation drawing 3 of 4All details on this drawing were assembled from the individually modeled components. AIRBORNE RESEARCH Client:

29. Installation drawing 4 of 4The upper two details were assembled from the individually modeled components. The wing detail is from the first drawing. AIRBORNE RESEARCH Client:

30. Patent drawing 1 of 2All of the details shown here were created from the modeled components. The notes were submitted on separate pages. AIRBORNE RESEARCH Client:

31. Patent drawing 2 of 2All of the details shown here were created from the modeled components. The notes were submitted on separate pages. AIRBORNE RESEARCH Client:

32. Inline Duct Damper This client supplies patented air control devices to the cleanroom industry. The following example was the first implementation of solids modeling to support the development of a new design for them. From the beginning of ATECS conception I had been providing their design development, fabrication, installation, and marketing drawings in 2D. This project presented it’s self as a good candidate to model. It assisted in clearly illustrating the concept to the team and in refining the design for fabrication. I utilized the model to also create the shop drawings with the need for very few 2D details. I continue to provide ATECS with 3D models for development and illustrations. Recently I’ve been creating new design prototypes as solids models that they’re using for air flow analysis testing in SolidWorks by a third party. This has eliminated the need to build a physical prototype. ADVANCED TECHNOLOGY EVIROMENTAL CONTROL Client: SYSTEMS ATECS Inc. Created with AutoCAD 2002

33. Cutaway of the assembled prototype model composed of over 50 individually solids modeled components. ADVANCED TECHNOLOGY EVIROMENTAL CONTROL Client: SYSTEMS ATECS Inc.

34. Fabrication drawing 1 of 3Fan blade assembly details created from the solids modeled components . Cutaway is a 2D detail. ADVANCED TECHNOLOGY EVIROMENTAL CONTROL Client: SYSTEMS ATECS Inc.

35. Fabrication drawing 2 of 3Fan blade and bracket details from model. Shafts and washers are 2D details. ADVANCED TECHNOLOGY EVIROMENTAL CONTROL Client: SYSTEMS ATECS Inc.
