Aérospatiale SA 330 Puma

The Aérospatiale SA 330 Puma is a four-bladed, twin-engined medium transport/utility helicopter designed and originally produced by the French aerospace manufacturer Sud Aviation.

The Puma was developed as a new design during the mid-1960s in response to a French Army requirement for a medium-sized all-weather utility helicopter. Powered by a pair of Turbomeca Turmo turboshaft engines, it was designed to transport up to 16 seated soldiers, or a maximum of six litters with four attendants for casualty evacuation, along with carrying up to 2,500 kg of cargo either internally or using an external sling. The design of the Puma incorporated several innovations, including an automatic blade inspection system and relatively advanced anti-vibration measures integrated into the main gearbox and main rotor blades. It was also designed to be capable of operating at night, under inhospitable flying conditions and in climates from Arctic to desert. The Puma also has an intentionally high level of reserve power to permit effective flight even at its maximum weight with only a single operational engine.

On 15 April 1965, the first prototype performed its maiden flight; the first production standard Puma made its first flight during September 1968. Deliveries to the French Army commenced in early 1969; the type quickly proved itself to be a commercial success. Production of the Puma continued into the 1980s under Sud Aviation's successor company Aérospatiale. It was also license-produced in Romania as the IAR 330; two unlicensed derivatives, the Denel Rooivalk attack helicopter and Atlas Oryx utility helicopter, were built in South Africa.
