A101 Introduction to Aerodynamics Section 1-1
__________________________________________________________________________
AERODYNAMICS
Outline
Today we shall :
• Review the scope of course and books
• Start our study of aerodynamics by
Identifying the flow properties
Aeroplane Design
Before starting our discussion on aerodynamics we should first consider how this topic fits
into the preliminary design of an aircraft. This will allow us to consider how this course
relates to other topics you will be learning over the next four years.
Perhaps the most important input into the preliminary design is some understanding of the
loads/forces applied to the aircraft and the associated airflow behaviour.
• The key aerodynamic properties of an aeroplane are
• Other important loads arise from
Knowing the forces we can then determine the performance and stability of the aircraft as
will be discussed in aircraft performance (A102 next term and A211 next year) and
mechanics (A109). The forces are also essential for us to consider how to design the aircraft
structure (A104/A110) which in turn will influence the weight. As you will see in your third
year courses (A3/403) much of this information in preliminary design is provided through a
combination of empirical and theoretical methods often with the aid of validated data sheets
such as the ESDU. An objective of this course and subsequent courses is to explain how this
data is derived from first principles and therefore allow you to see how aerodynamics can be
applied to many other disciplines such as racing cars or blood flow. It will also hopefully
provide you with the tools to discern the validity of data.
Although the topics we shall consider may appear to sometimes be quite abstract, you should
try and keep a general picture in your mind as to how aerodynamics can be applied to
determine the Lift, Drag forces and Moments on an aircraft. in lend
