Question 50Gas Turbine - 1st Asst/Chief70% to pass
What type of main lube oil supply and scavenging pump is installed on the marine gas turbine engine shown in the illustration? Illustration GT-0017
AI Explanation
The correct answer is C) Vane.
Vane-type pumps are commonly used as the main lube oil supply and scavenging pumps for marine gas turbine engines. Vane pumps are a type of positive displacement pump that use rotating vanes to move the lubricating oil through the system. This design is well-suited for the demands of a gas turbine engine, providing a reliable and efficient means of circulating the required lubricating oil.
The other options are not typically used for this application. Reciprocating piston pumps (A) are more common in diesel engine applications, while flexible diaphragm (B) and centrifugal (D) pumps are less suitable for the pressures and flow rates required by a gas turbine engine's lubrication system.
