Question 3Gas Turbine - 1st Asst/Chief
70% to passOn the gas turbine shown in the illustration, which of the following best describes the main principle of operation of the component contained within the area labeled "C"? Illustration GT-0001
ABernoulli's Law of Divergency
BNewton's Law of Motion
CCombustion at a constant pressure
DOtto Cycle
AI Explanation
The correct answer is C) Combustion at a constant pressure. In a gas turbine engine, the component labeled "C" is likely the combustion chamber or combustor. The main principle of operation of the combustor is combustion at a constant pressure, which is a key feature of the Brayton cycle that underlies the working of a gas turbine. The other options are incorrect because: A) Bernoulli's principle is not directly relevant to the combustion process, B) Newton's laws describe the motion of objects, not the thermodynamic principles of the combustion chamber, and D) the Otto cycle is applicable to internal combustion engines, not gas turbines.
