THE MAKING OF THE MoTIS MAJ210

Most of the detailed work for designing and developing a new neo concept aircraft comes in the form of the full development of the correct drawings. Before even one bulk head has been adjusted in an CAD/CAM program a complete set of blue prints needs to be designed and developed. This will create the full working backdrop for all of the subassembly parts that will go into making the design functional upon CAD translation from 2D design work. 

FIG.1

STEP 1 - All neo concept aircraft first start off as an idea that exist in the mind  of the neo concept designer. The idea is then traditionally turned into a 2D sketch and the idea is examined for feasibility study. For the purpose of the creations of a 3 Dimensional model, the idea is processed using an engineering drawing technique called Geometrical Dimensioning and Tolerance where the aircraft specs and design tolerances are created for the aircraft feasibility study in question.

FIG.2

STEP 2 - At MoTIS we use the CAD translation of our concept aircraft and start by manipulating several basic geometrical shapes into our desires conceptual model. in the case of the photo above, we converted a simple multiple bulk headed cylinder into the basic un streamlined shape of our fuselage. We typically start with the creation of our fuselage first as this is the main component where all the subassembly parts will come together.

FIG.3

STEP 3 -Shaping of the fuselage will be critical and the aircraft will be fundamentally recognized based on its unique fuselage structure. Bulkheads are properly placed and worked around a 2D design and the basic geometrical cylinder will start to look like a streamlined shape that has function.

FIG.4

STEP 4 - The next step in the design and development process is to cut the main fuselage for cockpit windows and doors as well as all articulating parts. As CAD manufacturing gives you a great variety of manufacturing processes, the major processing operations will be the proper use of the Boolean operation.

FIG.5

STEP 5 - Once the basic parts of the fuselage is cut then we can focus on the adding of the additional sub assembly parts like the empennage and the wing box. At this stage of the design the aircraft is most subject to creative alteration. During stage five of the design processing mission the aircraft should be in an experimental development stage and new configurations should be tried at numerous levels.

FIG.6

STEP 6 - Once the final design is standardized then all of the subassembly parts of the design needs to be joined to the main fuselage. The wings will be attached, the engines will be attached, and the landing gear will be properly placed. Also at this point in the design processing phase no detailed work will be conducted as numerous small changes are still being made to the aircraft.

FIG.7

STEP 7 - As the aircraft begins to crystallize out of the concept of the designers imagination then the aircraft continues to progress towards finally completion. What started as a simple geometric cylinder now starts to give the visual expression of a CAD aircraft! From the start of the CAD development process the aircraft really begins to come together as of the result of the bring together all of the subassembly parts being brought together into a composite whole.

FIG.8

STEP 8 - No matter what the design project or the basis of its complexity the Integrated Product and Process Design (IPPD) are the same. The aircraft is separated into component parts and designed as layers of subassemblies. the parts are then added together top make a full component and then the units are drawn down the product assembly line until each separate component is assembled into the final composite whole.

FIG.11

The project is laid out into a standard product and process network design.

STEP 9 - After all of the CAD development steps have been taken then the final design is converted into a Stereo Lithography File format (STL) file and is able to be set into a Rapid Prototyping 3D printer to get a full model of further analysis or as a final real world creation. In the case of this particular neo concept aircraft the aircraft is then translated into a complete 3 D model for testing across numerous simulated flight testing and visualization programs.
