ABSTRACT

This project thesis has been written at the request of Mälardalens University, Västerås.

The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course “Aircraft Engine Technology”.

                      The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.

Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate. Computations don’t match up with measured values. Also if the engine is inoperational, that would affect the education adversely.

The purpose of this project thesis is to find a suitable upgrade solution both economically and practically. The thesis was divided into three different bullet points:

  • Find the costings to renovate the existing Turbomin 100 turbojet engine. Also to find a suitable upgrade of the presentation of the measuring instruments to better clarify the lab. Motivate the disadvantages and the benefints respectively.
  • Find the costings to source new lab equipment matching the Turbomin 100 equipment and motivate why this would improve the lab. This purchase doesn’t need to be a purchase of an off-the-shelf solution, but can also imply the development of an inhouse solution. Motivate the disadvantages and the benefints respectively.
  • Develop a new lab instruction which matching one of the choosen alternatives above.

This study results in several solutions:

  • Proposal 1: The existing Turbomin 100 has such a solid construction that only a few spare parts needs to be replaced to get its original characteristics back. The use of measure equipment from Campbell Scientific consisting of a datalogger and associated software makes the presentation possible on a computer, from which printing easily can be done. This type of presentation would improve the understanding amongst the students for where and why the measurements are being made in certain areas of the engine. Estimated price for this solution is: 46.060 kr
  • Proposal 2: New lab equipment could consist of two different solutions. The first solution is to invest in two turbojet engines from JetCat with a thrust of 80N each. Having two engines would ensure the operations by having one operational and the other one as a spare when its time for the compulsory service after 50 hours of run time. This solution together with the above mentioned solution for measure equipment including pressure and temperature probes would cost around 104.300 kr.Another solution would be to invest in a complete engine and measure equipment from Turbine Technologies. Their turbojet engine comes in a test cabinet with all probes and instrument installed. Even a computer can be connected to get readings digitally. This makes it possible to print or even save the measured values. Quoted price for this solution is between 412.700 and 766.700 kr depending on solution.
  • Recommended solution from above is Proposal 1 will the new lab instructions look like attachment H.
