Preparation to be completed PRIOR to each class. Read or watch each link and answer questions under each assignment, below:
+++++++++++++++
date Session A: Introduction to
course: Early history of flight.
No Assignment for first class meeting
------------------ ------------------ ------------------
date Session B: 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.
------------------ ------------------ ------------------
date Session C: The Design
Process: What an Engineer does. We learn about materials, tools, and design. We begin to plan an airplane.
date Session D: Theory of
lift. Newton’s laws, Bernouli’s
Principle, and the Coanda Effect.
------------------ ------------------ ------------------
date Session E: Theory of lift,
continued as applied to aircraft.
date Session F: The Wing: parts,
nomenclature, chord, chord percent, aspect ratio, camber, incidence, various
kinds of wings and their purposes, dynamics of a turn.
------------------ ------------------ ------------------
date Session G: The Airfoil,
nomenclature, camber, structure, selection.
------------------ ------------------ ------------------
date Session H: Calculation of Wing Area and
Loading and its relationship to performance; .tiplets and wing tip vortices.
------------------ ------------------ ------------------
date Session I: 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).
------------------ ------------------ ------------------
date Session J: Stability
Concepts, continued.
------------------ ------------------ ------------------
date Session K: 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.
------------------ ------------------ ------------------
date Session L: Labs for working
on models – One plane per student, Each
workgroup has its own color for planes.
------------------ ------------------ ------------------
date Session M: Lab for trimming
models according to the material learned in this course.
------------------ ------------------ ------------------
date Session N: Show-N-Tell of
models by students using their design paper. Students evaluate planes according
to course material and appearance (part of grade).
------------------ ------------------ ------------------
date Session O: 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.
------------------ ------------------ ------------------
date Session P: Prepare for final exam.
