Project Course TMPM 01:The Future Gas Turbine

Siemens SGT-700

a cooperation with Siemens Industrial Turbomachinery, Finspång, Sweden

Project objectiveStudy the feasibility to replace the titanium alloy with a composite material in the blades in the first compressor stage on a SGT-700.

Motivation

• Light weight blade• Increased material damping• Tailored flexibility for blade - untwist

the NDA to a third party

• No material covered by the NDA can be handed over to the university staff(publicity principle)!

Further project information

• Course homepagehttp://www.mechanics.iei.liu.se/edu_ug/tmpm01/

• Siemens’ project specification http://www.mechanics.iei.liu.se/edu_ug/tmpm01/ht09/ProjectSpecPM.pdf

Course objectives

1. apply the inter-disciplinary knowledge in engineering mechanics obtained in previous courses to solve a complex, multi-disciplinary engineering problem,

2. independently find and assimilate information required to solve engineering problems, and

3. participate in managing, planning, executing and reporting industrial projects.

Project groups

• Engineering consultant groups• 4-5 students cooperate in a project group• Multidisciplinary groups• Group composition is assigned by the examiner• Each group is responsible for planning,

executing, managing and reporting the project.• Each group is responsible for requiring the

information and knowledge needed to complete the project

Resources

• In-house experts (teachers)• Support engineer at Siemens• Project room• ANSYS Workbench (FEM/CFD)• Library and databases (http://www.bibl.liu.se/?l=en&sc=true)

• Lectures• …

Examination

• Grades: U,3,4 and 5 (ECTS Fx,C,B and A)• Examination consists of six parts:

– Time report– Project time plan– Group contract– Project management– Project report– Project presentation– Engineering aptitude/skills

Examination (cont’d.)

• Each student keeps a time report

• Data, activity and duration (in hours)

• Signed and filed every week by the project leader

Time report

Week: 42 Year: 2009

Name: My Student

Date Activity12 Oct. FEM calculations, turbine blade 4 h

13 Oct. Literature survey, blade materials 5 h

Sum 11 h

Signature: My Project Leader

Examination (cont’d.)

• Project time plan is a brake-down the project into parts, or activities, to see their dependencies and duration

• Must include:– Activities, duration and cost (in hours)– Project leader periods (one for each member)

• Hand-in no later than Monday 20th Sept.

Examination (cont’d.)

Examination (cont’d.)

• Project management: each member is required to be project leader for one period (see project time plan)

• Responsibilities:– File, organise and keep relevant documentation– Check and sign time reports– Prepare progress report– Prepare any information the examiner requests– Inform the examiner about major unforeseen

problems etc.

Examination (cont’d.)

Where do we start?• Read Siemens’ project specification.• Read last years project reports.• Learn about gas turbines.• What do you know and what do you need to

know to do the project? • Write questions to the Siemens visit (hand-in by

e-mail Monday 14th Sept. to Jonas Stålhand).• Inventory of group members background. Is the

group lacking critical knowledge?• Try ANSYS tutorials, if you need.

Important dates in the near future

• First lecture (today)• Siemens questions (Mon. 14th Sept.)• Siemens visit (Thu. 16th Sept., 12-18)• Project time plan and group contract (Mon.

20th Sept.)
