- Introduction to course: Early history of flight.
- Basic concepts of flight – the essentials of an
airplane and how they are controlled. The 3 axes of stability and control.
Assignment of project and selection of teams. Method of working together to study and
design. Simulator?
- The Design Process: What an Engineer does. We learn about tools, drawings, and materials.
- Theory of lift.
Newton’s laws, Bernouli’s Principle, and the Coanda Effect.
- Theory of lift, continued as applied to aircraft.
- The Wing: parts, nomenclature, chord, chord percent,
aspect ratio, camber, incidence, various kinds of wings and their
purposes, dynamics of a turn.
- The Airfoil, nomenclature, camber, structure,
selection. Calculation of Wing Area and Loading and its relationship to
performance; .tiplets and wing tip vortices.
- Stability Concepts, Mean Aerodynamic Chord, Center of
Lift, The tailplane, its purpose and design. MAC and Center of Gravity calculations.
Stability techniques in modeling, dihedral, wing positioning, wing tip
wash-out for tip stall, Tail moment vs wing to stab area ratio. Sample Design Report. Video of poorly designed model (Shinden),
and of well designed model (Boo).
- Stability Concepts, continued.
- Presentation of drawings. Introduction to the craft of modeling,
materials, and tools. Safety
considerations, materials and adhesives. Survivability - weight, rubber
band attachment of wings and tail.
- Power systems
– gravity for gliders, Glide Ratio, motor power requirements
related to weight and drag. Thrust line, Propeller as airfoil. Relationship of power in to thrust. Possible thrust measurement and computer
efficiency curves.
- Labs for working on models – One plane per student, Each workgroup
has its own color for planes.
- Lab for trimming models according to the material
learned in this course.
- Show-N-Tell of models by students using their design
paper, Students evaluate planes according to course material and
appearance (part of grade).
- Flight of models from hillside. Three flights per plane, individual scores are top two flight
times added. Team scores are total
of individual scores normalized to number of students in each group. Plane must survive in flyable condition
after each landing or that flight is zero time. Video will be shared with
student body.
