Preface

In this block book you can find the activities that will take place during term 4 (or block 4) of the third year of the

Aeronautical Engineering course, specialisation Lightweight Structures.

First a short introduction is given followed by the competences you will be working on during this term. Block 4 is

divided into 3 units. In chapter 3 Learning Environment you can find an overview of the activities of these units.In chapter 4 you can find an overview of all modules (exams and assignments), including conditions and weights.

Check the Blackboard course regularly (10-11 AE3 TERM 4 LS)for recent and additional information.

1. I ntroduction

Term 4 is the first real Lightweight Structures term. In this term we will focus on the integration between analysis

and testing, optimisation in material and geometric sense and connection design. This means you will be working

on a number of competences, which you can find in the table in chapter 2.

In the course schedules you can find the learning goals of all units as well as an overview of the programme,

home work etc.

3.2 .1 Unit Conceptual Design Project LS

UnitConceptual Design Project LS

Course schedule Conceptual Design Project Wing Fuselage joint1. Learning goals:

The Project Wing Fuselage joint course focuses on the conceptual design of structures and joints in aircraft. In this context

the following learning goals are defined. After completion of the course the student is expected to:

1. be able to analyze structures and joint for aircraft applications,2. setup concepts based on customer and airworthiness requirements,3. Evaluate concepts based on technical and commercial criteria4. Be able to make detailed designs5. Make a testplan, execute this plan and evaluate the results compared to theoretical analysis6. Pre-calculate costs for quotation and evaluate the commercial results at the project.

4. Prior knowledge:

During this project students make use of their knowledge (and skills) from the first part of the minor -Light weight structuressuch as: Shell structures, Advanced CATIA and Mechanics

.

5. Teaching method

The project is carried out in groups with of four students in of which an active attitude is

expected. Groups are responsible for completing assignments during this term that lead to a

final report. During this term student will get lectures and workshop that support the project

activities.

Lectures are based on the project deliverables and prepare the students for the sub

assignments that need to be completed. It is expected that students prepare for the lectures

by reading the theory of that lecture prior to lecture.

Besides the project students will do a workshop, in which the most important theoreticaltopics will be applied and visualized. For this workshop an extra assignment will be provided.

6. Literature & other

learning materials

1. Course manual BlackBoard

2. R.Grit Project Management

3. M.C.Y. Niu Stress, Analysis and Sizing7. Use of Blackboard or

other (e-learning)

applications

The project manual and powerpoint slides will be published on Blackboard, as well as the

lecture notes for this course.

8. Assessment

At the end of the term there will be report generated by the group.

The exam will be assessed with a grade: 50% of all points will lead to a grade 55.

There is one resit possibility.

write a proposal based on an invitation to tender

present a proposal in a convincing manner

estimate costs; do cost calculations

take business and financial aspects into account.

3. Prior knowledge:

During this project students make use of their knowledge of project management, traineeships and communication.

.

4. Teaching method
