What is the function of the two parallel rods at the engine mount?

• A. To connect the AGB and engine sections
• B. To stabilize the helicopter during flight
• C. To reduce vibrations
• D. To improve fuel efficiency

Answer: (A)

The function of the two parallel rods at the engine mount is primarily to connect the accessory gearbox (AGB) and engine sections. This connection is crucial as it helps ensure that the engine components operate in a coordinated manner, allowing for efficient power distribution and functioning of the engine. The rods provide structural support and maintain alignment, which is essential for the engine's performance and the overall stability of the system. By securely linking these vital components, the rods contribute to the proper functioning of the helicopter's propulsion system.

While other functions such as stabilizing the helicopter during flight, reducing vibrations, or improving fuel efficiency might be influenced by the engine mount's overall design, the primary and most direct role of the parallel rods is indeed as a connection between the AGB and engine sections.
