Question 147Gas Turbine - Assistant Engineer

The correct answer is B) In the direction of turbine rotation. The turbine nozzles function to direct the high-pressure, high-velocity gases exiting the combustion chamber onto the turbine blades. This causes the turbine to rotate, which in turn drives the compressor and other components of the engine. The direction of the nozzles is designed to impart the maximum amount of rotational force to the turbine, which means directing the gases in the same direction as the desired turbine rotation. The other answer choices are incorrect because: A) would reduce the rotational force on the turbine, C) would not impart any rotational force, and D) would not efficiently transfer the energy from the gases to the turbine.
