    US Coast Guard HH-65 Dolphin

    The Aerospatiale SA366G1 Dauphin was selected by the United States Coast Guard in 1979 as its new short range recovery (SRR) air-sea rescue helicopter, replacing the Sikorsky HH-52A Sea Guard. In order to comply with american regulations relating to local content, engineering changes were required: most notably the french original Turbomeca Arriel engines were replaced with Lycoming LTS101 powerplants. The Dolphin normally carries a crew of four: pilot, copilot, flight mechanic and rescue swimmer.

    Notice in the above video the little fan on the top of the main rotor. It is called the OADS (Omni-directional Air Data System), It spins around and measures differences in air pressure to indicate relative winds. The system was set to be removed in the MH-65D variant as it was extremely maintenance intensive and not very accurate.
