摘要:
The invention provides a communication system of voice and data messages between two or more aircraft for managing a flying operation, such as a tanker aircraft (11) and a receiver aircraft (13) during a refueling operation, that can be used in adverse environmental and/or operational conditions. The communication system is implemented by a free space optical data link between both aircraft which is compatible with radio silence conditions since it is not based on radio frequency transmissions and comprises first and a second segments (21, 41) in the first and second aircraft with communication control modules (25, 45) adapted for converting the messages of voice and/or data in electrical signals and vice versa and optical modules (23, 43) adapted for emitting beams of light modulated by said electrical signals and for converting received beams of modulated light in electrical signals.

The invention provides a device for aerial transportation and treatment of patients in litters. The device comprises several structural elements (legs (15a, 15b), upright posts (17a, 17b), litter clamping arms (19a, 19b), reinforcing members (21, 23)) and several connecting terminals (31) between them allowing its installation in commercial aircraft quickly and easily, without any tools. The structural elements are formed by hollow metallic profiles (20), preferably of aluminum, of square section, including in their four faces recessed channels (40) with undulated walls such as the rails of the AS 33601 standard.

The invention provides a structure for an aircraft which prevents puncture of composite skins when they are struck by lightning. The structure comprises a composite skin (1) having an outer face intended to be exposed to open air and at least one inner face, and a ballistic material layer (2). The ballistic material layer is provided on an inner face of the composite skin which is not intended to be exposed to open air. The invention also provides an aircraft comprising this structure, a method of upgrading an aircraft and a use of a ballistic material layer as protection against lightning impact in an aircraft structure.
摘要:
A digital audio system of an aircraft comprising one or more audio equipment (11) and one or more radio equipment (47) providing a reliable side tone to the operators. The audio equipment (11) and the radio equipment (47) have installed in the proximity, respectively, an audio-terminal (27) and a radio-terminal (45) connected to a digital network (15) including digital messages management units (37, 57) and digital signal processors (39, 59). The digital messages management unit (37) of the audio equipment (11) is provided with a computer program adapted to generate a side tone of an analog audio message issued by the microphone (21) of the audio equipment (11) and to activate/deactivate its sending to the headset (25) of the audio equipment (11) when the audio-terminal (27) receives from the radio-terminal (45) an activation/deactivation command for said side tone.
摘要:
A guidance apparatus mounted on the belly of a tanker aircraft for providing visual indications to the pilot of the receptor aircraft with respect to the approaching operation to carry out the refueling by means of a refueling boom is provided. The guidance apparatus comprises light emitting devices (11) including modules of light emitting diodes (LEDs) and control devices (41, 61) for supplying current to them that include dimming control units (45, 65) for controlling the intensity of the light emitted by said light emitting devices (11) by means of a dimming signal depending on a dimming voltage ( Vdim ). The dimming control units (45, 65) are adapted to provide to the light emitting devices (11) a pulse-exponential amplitude modulated dimming signal ( Vref2 ) so that the light intensity can be properly controlled in all visibility conditions.
