Brief Handbook Description: This unit of study should prepare students to be able to undertake aerodynamic performance calculations for industry design situations.

The unit aims to develop a knowledge and appreciation of the complex behaviour of airflow in the case of two dimensional aerofoil sections and three dimensional wings; To encourage hands-on experimentation with wind-tunnel tests to allow an understanding of these concepts and their range of applicability. To understand the limitations of linearised theory and the effects of unsteady flow.

At the end of this unit students will be able to: predict flow properties for general aircraft wing sections to obtain lift, drag and pitching moment; extrapolate section results to predict full three dimensional wing behaviour; undertake experiments and analyse data to verify theoretical predictions; construct simple computer algorithms that will allow more complex geometries to be solved; understand the limitations of theory and the effect of second order parameters (Reynolds number, Mach Number) to the primary flow properties.

Course content will include: construction and designation of two dimensional aerofoil sections; point vortex model of aerofoil; Joukowski transformation theory; thin aerofoil theory; linear lift properties for sections; limiting effects such as stall; calcualtion of pitching moment coefficient; methods for estimation of boundary flow and friction drag calculations; viscous-inviscid panel method numerical solutions; modelling of three dimension wing flows; lifting line theory and vortex lattice method; effects of downwash, aspect ratio, sweep angle and asymmetry.
Assumed Knowledge: Mathematics and Physics to the level of Bachelor of Science or equivalent. Linear Mathematics and Vector Calculus, Partial Differential Equations (Intro).

# Name Group Weight Due Week Outcomes

7 Design, Built & Test Yes 10.00 Multiple Weeks 1, 3, 7, 8,
Assessment Description: * indicates an assessment task which must be repeated if a student misses it due to special consideration. Weekly submissions will be required as specified in classes. Final report will be a compilation of the submitted components. Penalties apply for non-submission.

Assignment: Application of potential flow to aerofoil analysis.

Laboratory 1: Pressure measurement around an object. Understanding or Reynolds number effects

Assignment: Analysis of 3D wings. Peer assessment will be used to determine each student`s final mark.

Laboratory 2: Analysis of aerofoil section. Stall and separation effects

Design, Build & Test: Design an aerofoil, build and pressure tap, and test. Peer assessment will be used to determine each student`s final mark.

Final Exam: 2 hour examination at end of semester. Revision of theory and concepts. It is a requirement that to pass the course you must achieve 40% of the examination mark regardless of the sum of your individual marks.

There may be statistically defensible moderation when combining the marks from each component to ensure consistency of marking between markers, and alignment of final grades with unit outcomes.

The penalty for lateness is 5% per day. The penalty would apply from the next calendar day after the deadline.

The penalty is a percentage of the available mark and is applied to the mark gained after the submitted work is marked (e.g., an assignment worth 100 marks is 1 day late. The content is given a mark of 75. With the 5% penalty, the final mark is 70).
Grading:
Grade Type Description
