Title : Space Mouse

Department Of Aerospace Engineering

Project Intro: Every day of your computing life, you reach out for the mouse whenever you want to move the cursor or activate something. The mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately. An ordinary mouse detects motion in the X and Y plane and acts as a two dimensional controller. It is not well suited for people to use in a 3D graphics environment. Space Mouse is a professional 3D controller specifically designed for manipulating objects in a 3D environment. It permits the simultaneous control of all six degrees of freedom - translation rotation or a combination. The device serves as an intuitive man-machine interface The predecessor of the spacemouse was the DLR controller ball. Spacemouse has its origins in the late seventies when the DLR (German Aerospace Research Establishment) started research in its robotics and system dynamics division on devices with six degrees of freedom (6 dof) for controlling robot grippers in Cartesian space. The basic principle behind its construction is mechatronics engineering and the multisensory concept. 

The spacemouse has different modes of operation in which it can also be used as a two-dimensional mouse.

AERODYNAMICS

SECOND EDITION

A COMPLETE COURSE IN ELEMENTARY AERODYNAMICS WITH EXPERIMENTS AND EXAMPLES

PREFACE TO SECOND EDITION: The present edition is enlarged to provide, in the first place, an introduction to the mathematical and experimental study of compressible flow, subsonic and supersonic. This and other matters now becoming prominent are not collected in a supplementary section but incorporated in place as additional articles or short chapters. Following a well-established practice, the numbering of original articles, figures and chapters is left undisturbed as far as possible, interpolations being distinguished by letter-suffixes. It is hoped this procedure will ensure a minimum of inconvenience to readers familiar with the earlier edition. To some extent the unlettered articles indicate a first course of reading, though a modern view of Aerodynamics requires consideration of Mach numbers equally with Reynolds numbers almost from the outset. Other matters now represented include various theories of thin aerofoils and the reduction of profile drag. The brief account of the laminar-flow wing is in general terms, but the author has drawn for illustrations on the conformal system, in the development of which he has shared more particularly. The original text is revised to bring it up to date, and also in the following connection. Experience incidental to the use of the book at Cambridge and London Universities isolated certain parts where the treatment was insufficiently detailed for undergraduates ; these are now suitably expanded. The aim of the book remains unchanged. It does not set out to collect and summarise the researches, test results and current practice of the subject, but rather to provide an adequate and educational introduction to a vast specialist literature in a form that will be serviceable for first and higher degrees, and like purposes, including those of the professional engineer.

Title: ANALYSIS OF CASTING PROCESS FOR COMPLEX ELECTRONIC UNIT

Development Of Aerospace and Materials Engineering

Project Aim And Summary: This thesis consists of six main chapters.

Chapter 1 gives a general introduction to the thesis.

Chapter 2 discusses the general concepts involved with process and material selection as well as brief descriptions of aluminum alloys, casting processes and simulation of casting processes.

Chapter 3 lays down the main tasks performed and decisions made prior to simulation, which includes modification of the geometry as well as choice of material (alloy) and process. Chapter 4 presents some simulation results and discusses various changes and improvements made on the simulation of the processes. Chapter 5 gives a rough cost estimation of the chosen processes and the last chapter. 

Chapter 6 gives the conclusion part of the whole thesis.

In addition, reference materials used for this thesis and an appendix, consisting of various tables and figures, are provided in chapters 7 and 8 respectively.

The aim of this thesis work was to:

1. Modifying the products geometry to have better castability

2. Choose a casting process

3. Choose an alloy material

4. Have a sample gating system

5. Show areas susceptible to defects

6. Proposal of secondary processes and testing

7. A rough cost estimation

Abstract: Most aircraft component are currently being manufactured by machining, forging, welding and also assembling such parts. However, the possibilities of cutting cost from a single component has brought about a growing trend towards looking into casting as a possible option for manufacturing aircraft parts. This thesis was done at the request of Saab Avitronics. It evaluates the possibilities of one aircraft part, a chassis for an electronic unit that was first designed to be machined from a blank, to be cast. The thesis goes through the multifaceted tasks of product development. Casting process selection, cast alloy selection as well as geometry modification were some of these tasks that were performed in this thesis. It also evaluates the performances of chosen casting processes, the design of gating systems as well as various process parameters set, by simulating the casting processes. The alloy chosen was A356.0 with a T6 temper and the casting processes chosen were plaster mold casting and rheocasting. The geometry of the original chassis, which had very thin sections and undercuts which were complex to cast, was modified and made easier to cast with an acceptable slight increase of mass and size. The modification done on the geometry as well as the gating systems used had proven to be worthwhile, as the simulation of both process showed that such a part can be casted with no crucial defects foreseen. However, probable cavities might occur at the very tip of the chassis‟s thin-fins – that it has for carrying away heat. Minor subsurface porosities might also be formed, which would not impair the function of the chassis. The modified chassis was made as close to as finished piece as possible, for the purpose of reducing machining costs. The cost of producing such a part by casting was also seen to be much less than machining it from blank. This could be taken as rationale for casting the chassis with thicker sections, to avoid problems that may arise in casting, and to subsequently machine these faces later, as it would still be cheaper than machining the chassis from a blank.

Key Words: design for casting, casting process selection, simulation of rheocasting, simulation of plaster mold casting, casting cost estimation.
