  • Patent number: 10551266
    Abstract: A device measures a flight parameter of an aircraft which has a radome. Systems measure the deformation of a wall of the radome due to forces exerted by the air on the radome. A computer computes the flight parameter from deformation measurements obtained by the systems. The systems have an optical fiber carried by the radome provided with Bragg gratings. Each fiber has a plurality of Bragg gratings distributed over a length of the fiber so as to distribute the Bragg gratings over the radome when the fiber is installed.
