Design Topics:
Introduction to Aircraft Design:
A. Understanding of Flight ScienceB. Understanding of Structural Science during flightC. Design considerationsD. Utilization of Design ToolsE. Preliminary Design with focus on "Design Intent"F. Imagination and Creativity
Flight Science
• How can things FLY ?– Propulsion or Power– Wing or Airfoil – Control Surfaces– Air on Earth ( not in Space )– Light Weight Materials on Earth ( not in Space )– Body that can withstand air pressure and friction– Pilot or someone in control– Speed !!!!!
Structural Science
• Design of Primary Structures– Fuselage, Wing, Tail, Floor, Engine Mount, etc
• Design of Secondary Structures– Seats, Overhead Storage, Cabinets, Toilet, Clips, etc
• Design of Landing Gears– Nose and Main Gear Struts, Breaks, Tires, etc
• Design of Control Surfaces– Wing Flaps, Tail Ruder, Connor, Horizontal Tail
Design Considerations
• Mission of the aircraft• Range and duration in flight• Size and Capacity• Commercial or Military• Manned or Un-manned (UAV)• Stealth ?• Material and Testing• How many to be built and maintainability• Cost and Safety
Designing Tools
• Which CAD systems to use?– AutoCAD– Pro-E– Unigraphics– CADKEY– Solid Works– CATIA
Preliminary and Design Intend
• Configuration Layout• Primary Structural Layout• Internal Systems Layout• Material Utilization / Selection Layout• Establishing Center of Gravity • Establishing Thrust to Weight Ratio• Establishing Limitations of Manufacturing• Establishing Vendor’s Limitations
Imagination and Creative Thinking
• First Imagine• Show Creativity in solving problems• Compare theories with real test results• Test and more Test• Learn from others but “Don’t Copy”• Imagine you are the pilot what would you
like your aircraft do for you !
