# AERODYNAMICS - 2020/1

Module code: ENG3167

## Module Overview

Third year module in Aerospace Engineering.

The module is lecture and tutorial based and continues to develop the understanding of aircraft aerodynamics and design started in ENG2089 and ENG2091 by concentrating on the prediction of lift in incompressible flow, the characteristics of laminar and turbulent boundary layers, compressibility effects in subsonic and transonic flow, and the impact of these topics on the design of aircraft in civil aviation.

## Assessment pattern

Assessment type Unit of assessment Weighting
School-timetabled exam/test IN-SEMESTER TEST (40 MINS) 20
Examination EXAMINATION (2 HRS) 80

## Alternative Assessment

Coursework to replace test.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, the ability to adapt and apply those principles to specific calculations and the ability to describe aspects of aerodynamic phenomena and aircraft design. The class test demonstrates the ability to perform a specific calculation and interpret its results.

Thus, the summative assessment for this module consists of:

• Examination (Learning outcomes 1-5)                2 hours     (80%)

• In-semester test (Learning outcome 1)              40 mins     (20%)

• Coursework as an alternative to the class test for summer reassessment       (20%)

Formative assessment and feedback

Verbal feedback and discussion is provided during tutorial classes

Written feedback is provided on the class test

Feedback is also provided via material on SurreyLearn

## Module aims

• To provide an understanding of methods for predicting lift in incompressible flow and in supersonic flow, including the effects of finite aspect ratio.
• To provide a general appreciation of the aerodynamics of transonic flow and understanding of means of estimating the extent of the transonic regime for any particular streamlined body.
• To provide an introduction to laminar and turbulent boundary layers and their importance in determining drag on an aircraft.
• To bring these strands together in a broad discussion of the design of subsonic, civil aviation aircraft.
• To provide an introduction to laminar and turbulent boundary layers and their importance in determining drag on an aircraft.
• To bring these strands together in a broad discussion of the design of subsonic, civil aviation aircraft.

## Methods of Teaching / Learning

The learning and teaching strategy is designed to develop subject knowledge through theory, applications and worked examples. The module content is delivered through lectures, tutorial classes and SurreyLearn material.

The learning and teaching methods include three hours of lectures per week for ten weeks and one hour of tutorials per week for ten weeks, together with eight hours of revision classes. Related material is provided on SurreyLearn

48 contact hours, 102 hours independent study, total 150 hours learning time

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
