REMOTE COMMUNICATION SYSTEM FOR AIRCRAFT Russian patent published in 2018 - IPC B64C11/26 B64D45/00 G01N21/88 

FIELD: measurement; testing.

SUBSTANCE: invention relates to a remote communication system capable of being incorporated into aircraft (1A, 1B, 1C), comprising at least one motor propeller (50A, 50B, 50C) having plurality of blades (52A, 52B, 52C) capable of rotating relative to fixed module (10A, 10B, 10C) of the aircraft about drive shaft (X). Remote communication system comprises: an optical transmission device configured such that, when the system is incorporated into aircraft (1A, 1B, 1C), it transmits a light beam that emerges out of propeller (50A, 50B, 50C), from at least one transmitting surface (54A, 54B, 54C) of said propeller (50A, 50B, 50C); and an optical device for detecting the light beam, comprising at least one detecting surface (14A, 14B, 14C) that is sensitive to the light beam, and that is capable of being incorporated into fixed module (10A, 10B, 10C) in such a way that said at least one transmitting surface (54A, 54B, 54C) and said at least one detecting surface (14A, 14B, 14C) repeatedly come to face each other, at a distance from each other, when propeller (50A, 50B, 50C) rotates relative to fixed module (10A, 10B, 10C).

EFFECT: invention also relates to an assembly comprising a propeller, a fixed module and a communication system.
