Abstract
Training simulators are used in a variety of industries that require the skill of handling complex or sophisticated technologies and having knowledge of advanced controls. Training simulators have a long history; a number of studies have already been done to make the training simulators more flexible.
Jet engine testing operators have to follow a proper methodology to carry out the procedures of safe engine testing. While performing the tests, the operators have to deal with various emergency conditions and should have proper information on how to deal with those situations. This thesis presents the design and development of a training simulator for aviation engine testing operators. Engine simulation software, GasTurb, is used to develop the jet engine model files and to get the output variables from the simulator. These model files are made accessible in Simulink (MATLAB) with the help of second order S-function. The S-function accesses the Dynamic Link Library (DLL) of GasTurb, to read the model files and to provide real time output on the basis of inputs from external hardware. The user interface to display these output values is developed in Unity game engine. Five different emergency scenarios have been designed and evaluated using the developed simulator.
Related variables for these emergency scenarios are plotted to compare the reaction of the operators. The feedback is also taken from the operators regarding the effectiveness of training simulator. The result shows that training simulator would promote and develop their understanding of process. It would help to enhance the ability of operator to identify parameters causing the emergency scenarios and enable them to overcome such situations.
