LEARNING
OBJECTIVES
|
|
- Introduce
students to the fundamental concepts of atmospheric flight
dynamics
- Enable
students to analytically estimate static and dynamic stability
derivatives
- Enable
students to study the stability of longitudinal and lateral motions
using the linearized equations
- Enable
students to obtain responses to actuation of open-loop and closed-loop
controls
- Enhance
the students’ written, oral, and graphical communication skills
|
|
|
COURSE
GOALS
|
|
- Overview
principles of flight and the classical/modern theory of stability and
control
- Present
conventional and unified notation for flight mechanics variables,
forces, and moments
- Derive
classical, uncoupled rigid body equations of motion used for S&C
analysis of aircraft
- Define
and physically explain the static and dynamic stability and control
derivatives
- Understand
the concepts of equilibrium, neutral point, trim, etc.

transfer function representation, dynamic stability, and modes of
motion
- Present
examples of flight models used in analysis and design

PROJECT
|
|
Select one of the two projects illustrated next:
1) To enhance learning, the students are required to evaluate the stability
and control characteristics of actual airplanes. Each team (of two
students) selects an airplane, obtains its geometric and mass data, computes
stability and control derivatives, and studies the longitudinal and
lateral-directional motions. Students submit work-in-progress reports
at mid-semester and final reports at the end and make oral presentations.
2) To enhance learning, the students are required to find one or more
literature article (from a journal, book, etc.) where the problem of
stability and control of airplanes has been treated. Each team (of two
students) should choose any of the topics under the general category of
stability and control of airplane. However, aside from this constraint, the
primary driving force in the selection of the paper topic should be your
interest. You should review the literature in order to become familiar with
your topic and the issues surrounding it. Students submit work-in-progress
reports at mid-semester and final reports at the end and make oral
presentations.
Note: Start this assignment early! ALL topics must be approved by the
instructor, due date: first week of October.
