This course provides an overview of the fixed-wing airplane sizing process. It is applicable to jet transport, turboprop commuter transport, military (trainers, fighter bomber, UAV) and general aviation aircraft. The design process covers sizing (weight, wing area, thrust/power), drag, high lift device sizing, weight and balance, stability, control and geometry. Numerous examples are shown. Lessons learned and "what to watch out for" are discussed. Please note: If you prefer a more in-depth course on this subject matter, please review this instructor's course: Airplane Preliminary Design.
- Introduction to airplane design: flowchart of the design process
- Review of drag polar breakdown for subsonic and supersonic airplanes, rapid method for drag polar prediction, check of drag polar realism
- Two airplanes: same mission, different design: comparison of the Boeing B-47 with the B2 Vulcan
- Preliminary sizing of airplane takeoff weight, empty weight and fuel weight for a given mission specification: applications; sensitivity of takeoff weight to changes in payload, empty weight, range, endurance, lift-to-drag ratio and specific fuel consumption; role of sensitivity analyses in directing program-oriented research and development: applications
- Performance constraint analyses: relation between wing loading and thrust-to-weight ratio (or wing loading and weight-to-power ratio) for the following cases: stall speed, takeoff field length and landing field length, statistical method for estimating preliminary drag polars, review and effect of airworthiness regulations; relation between wing loading and thrust-to-weight ratio (or wing loading and weight-to-power ratio) for the following cases: climb and climb rate (AEO and OEI), cruise speed and maneuvering; the matching of all performance constraints and preliminary selection of wing area and thrust required: applications
- Preliminary configuration selection; what drives unique (advanced) configurations? Discussion of conventional, canard and three-surface configurations; fundamentals of configuration design
- Preliminary Design Sequence:
- Type of propulsion
- Wing planform
- Type, size and disposition of high lift devices
- Layout of empennage (horizontal tail, canard, V-tail, vertical tail sizing)
- Type of landing gear
- Preliminary drawing (CAD)
- Class I weight and balance including loading diagram
