Rotorcraft having lighting equipment with a plurality of headlights operated for landing, winching, and searching

摘要

A rotorcraft (1) having on-board lighting equipment for lighting the surrounding environment. The lighting equipment comprises a plurality of headlights (2, 2′, 3, 3′) that are allocated to respective specific lighting functions in landing and in winching. The headlights (2, 2′, 3, 3′) are also operated to perform a searching lighting function. Control means determine which headlights (2, 2′, 3, 3′) are to be operated depending on a lighting function selected by an operator and depending on where the headlights are located on the rotorcraft (1). A search zone (4, 4′) for illuminating is identified by identification means on the basis of a lighting command common to the headlights (2, 2′, 3, 3′). Coordination means cause the headlights (2, 2′, 3, 3′) to converge on the identified search zone (4, 4′), while taking account of their respective locations on the rotorcraft (1).

主权项

1. A rotorcraft having on-board lighting equipment for lighting the surrounding environment, the lighting equipment comprising a plurality of lighting devices for lighting specific remote zones for illumination, the lighting equipment including at least a landing lighting device and a winching lighting device, each of the lighting devices having at least one headlight comprising a unit housing a lighting module having an optical system and a light source, and control means for controlling the emission of a light beam by the headlights, the headlights from the landing lighting device and winching lighting device forming a group of headlights, the landing lighting device and winching lighting device selectively cooperatively defining a searching lighting system, the searching lighting system comprising at least two searchlights providing a searching lighting function, the at least two searchlights comprising at least two headlights from the group of headlights mounted to move on the rotorcraft and fitted with drive means for driving the searchlight in azimuth and in elevation relative to the rotorcraft, the drive means being operated by search control means from a search lighting command to light a search zone for illumination, which command is generated by at least one search control member operated by a human, the headlights of the landing lighting device and winching lighting device being distributed over the rotorcraft in a landing lighting function and a winching lighting function, the searching lighting function obtained by applying a search lighting command common to all of the headlights, and on the basis of selective activation by the control means of the headlights of the lighting equipment.
