Aircraft Catapult Lubrication System: Important Information

What is the purpose of the relief valves in an aircraft catapult lubrication system?

Choose the correct answer:

a) To regulate the flow of lubricant

b) To relieve excess pressure in the system

c) To control the temperature of the lubricant

Answer:

The correct answer is b) To relieve excess pressure in the system.

Relief valves in an aircraft catapult lubrication system play a crucial role in ensuring the system functions safely and effectively. These valves are designed to relieve excess pressure that may build up in the system during operation.

When the pressure exceeds a specific threshold, the relief valve opens to divert the excess lubricant or fluid, preventing overpressure conditions that could potentially damage the system components or compromise the safety of the aircraft.

It is essential for the relief valves to be set to the correct pressure level to provide adequate protection and prevent system failures. Manufacturers typically specify the pressure at which the relief valves should actuate based on the design and specifications of the catapult lubrication system.

Regular maintenance and inspections of these relief valves are necessary to ensure they are functioning correctly and provide the required protection for the aircraft catapult system.
