SA365 Dauphin 2 Specifications:

In January of 1975, Aerospatial/Eurocopter flew the first twin-engine Dauphin helicopter, designated AS-365. It was developed from the SA-360 single-engine, which was up-sized from the SA341 Gazelle. Although the SA365 resembled the SA360, it was essentially a complete re-design. New to the AS365 Dauphin 2 (in 1977) was the Starflex rotor system, which eliminated the need for complex hinges.

From the original AS365C, the AS365N was developed. Although it appears similar, there is over 90% new or improved parts. The N-models make extensive use of composite materials for the structure. The composite rotorblades used a different, more efficient, quieter and faster airfoil.

The AS365F was a naval variant of the AS365N built specifically for several navies. The AS365Fi was the first version to incorporate a glass panel rather than the usual steam-gages.

The AS-366G was developed in response to a search and rescue helicopter order from the US Coast Guard, designated the HH-65 Dolphin. The primary difference was the mission-specific instrumentation and replacing the Turbomecca Arriel engines with Honeywell Lycoming LTS-101 engines. Recently the Coast Guard replaced the LTS-101 engines with updated FADAC Arriel engines.

The current military version is the AS565 Panther in tactical land-based missions and naval operations, and the AS365 FS for anti-ship and ASW missions. Additionally, the Harbin Aircraft Manufacturing Corporation was granted a license to build the Z-9 Chinese version.

The current civil growth version of the Dauphin is the EC155, which was originally designated the AS365N4. In it's current form, it received certification in December 1998 and customer deliveries started in March of 1999. More than 650 Dauphin helicopters have been produced to date making it one of Eurocopter's most successful airframes.
