Question 148Gas Turbine - Assistant Engineer

The correct answer is A) Convert the heat energy of the hot gases into kinetic energy and direct the flow of gases to the turbine rotor blades. The turbine nozzle guide vanes are designed to convert the heat energy of the hot gases coming from the combustion chamber into kinetic energy. This kinetic energy is then used to drive the turbine rotor blades, which in turn drive the compressor and other components of the gas turbine engine. The other answer choices are incorrect because they do not accurately describe the primary functions of the turbine nozzle guide vanes. Option B is incorrect as the vanes do not convert potential energy into heat energy. Option C is incorrect as the vanes direct the flow to the turbine rotor blades, not the compressor rotor blades. Option D is incorrect as the vanes convert heat energy into kinetic energy, not potential energy.
