What engine type powers the Puma helicopter?

The Puma helicopter is powered by two Turbomeca Turmo turboshaft engines, which provide it with the necessary lift and power for various operations. The design of the Turmo engines allows for high reliability and efficiency, crucial for the multi-role capabilities of the Puma. The use of twin engines ensures redundancy, enhancing safety and performance, especially in demanding environments where power output and reliability are critical. The turboshaft configuration enables effective energy conversion from fuel, maximizing the helicopter's operational range and payload capacity.

The other engine options mentioned, like the Pratt and Whitney Turbo or the Avro Lycoming engine, do not apply to the Puma and are associated with different aircraft types, which eliminates them from consideration. The twin Turbomeca Turmo engines are specifically engineered for the Puma, making them the correct answer.
