DAUPHIN AS 365 N2

The Dauphin AS 365 N2 is a medium-weight multipurpose civil twin-engine helicopter. In addition to technological innovations (main and rear rotor blades made of composite materials, tail rotor built in the fin...), the reliability and availability of this helicopter are highly valued worldwide. The AS 365 N2 is equipped with two Turbomeca Arriel 1C2 engines which offer remarkable performance. This machine is particularly well designed for transporting passengers (Offshore, Corporate or VIP) and for carrying out missions in the Public Services (Police, Fire-fighting...).

With its cabin flexibility, its low vibration level as well as its big choice of optional equipment, this helicopter meets all requirements of a wide mission range.

DAUPHIN AS 365 N3

The main modification made to the N3 version resides in a change of engines, giving the helicopter greater power. But the definition of the Dauphin AS 365 N3 also takes into consideration the requirements arising from the noise pollution reduction regulations. This is why the Dauphin AS 365 N3 received a main rotor with a variable rating capability.

The significant improvement in the AS 365 N3's performance is mainly due to the adoption of the latest edition to the family of Turbomeca's Arriel engines.

In fact, the Arriel 2C fitted on the N3 is 18% more powerful than the Arriel 1C2 which fits the N2 version. The Arriel 2C engine has an advanced electronic engine control (FADEC), whose advantages are already acknowledged as to a better use of the available power; it has also benefited from single-crystal free turbine blades, which enable higher operating temperatures, providing higher operating power.

In twin-engine flight, this increase in power can be used in warm weather or at high altitude to increase the helicopter's take-off weight significantly. Thus for altitudes between 1,000 m and 3,000 m, for instance in ISA +20C condition, out of ground effect, the N3 version can carry a payload 300 kg heavier than the N2.

In single-engine flight, the helicopter's ?'category A'' performance capabilities will comply with the new regulatory requirements.

Still in ISA +20C conditions but now at sea level, the N3's payload is increased by almost 500 kg with respect to the N2 in the case of take-off from building roofs in urban aeras. The Dauphin AS 365 N3 is therefore particularly well suited to comply with the requirements of both European operators, subject to ever stricter regulations, and civil and public services operators confronted with warm temperatures or high altitudes (South America, South East Asia, Middle East).
