Problems solved by technology

In order to prevent frost from depositing on the detectors, the detectors had to be equipped with heating means: this increased the volume of the detectors and thus increased the size of the protrusions on the skin of the aircraft

Embodiment Construction

[0038] The system for monitoring anemometer, barometric and inclinometric parameters of the present invention proposes, in addition to or as an alternative to conventional measurement circuits or circuits, the use of optical Laser type anemometer for measurement. In fact, laser anemometers allow the measurement of certain anemometry, barometric and inclinometric parameters, in particular the velocity of the aircraft in its three directions (thus measuring its velocity vector), thus enabling the acquisition of the aircraft's angle of attack and The sideslip component of the aircraft.

[0039] Laser anemometers work by measuring the deflection of monochromatic light waves, especially laser light waves, after being scattered back (rétrodiffusée) by aerosols (particles and / or molecules) present in the atmosphere. This offset allows determination of the component of the velocity vector along the optical axis. In other words, the laser anemometer emits laser radiation at a predete...

Abstract

The invention concerns a system for monitoring anemobaroclinometric parameters in an aircraft, comprising a primary detection circuit (1) including at least one measuring channel (10), said measuring channel comprising: a device for measuring a static air pressure (13, 14); a device for measuring a side-slip angle of the aircraft; a device for measuring (15) a dynamic pressure, a total temperature and an angle of attack of the aircraft; and a data processing device (12) adapted to determine anemobaroclinometric parameters based on the measurements of static pressure, side-slip angle, dynamic pressure, total temperature and angle of attack; at least one laser anemometer (50) for measuring a true speed parameter of the aircraft.

Description

technical field [0001] The invention relates to a system for monitoring anemobaroclinométrique parameters in an aircraft. The system can be used to obtain on board the aircraft the values ​​of wind speed, barometric pressure and inclination measurement parameters relevant to the flight of the aircraft. Anemometry parameters are parameters related to the position and velocity of an aircraft in flight relative to the surrounding air. [0002] The invention is applicable in the field of aeronautics, in particular in the field of measurement of parameters related to anemoclinométrie (vertical anemometry) of aircraft. Background technique [0003] On board an aircraft it is important to obtain certain information related to the flight of the aircraft. Anemometry techniques allow obtaining such information, in particular the speed of the aircraft, its spatial position relative to the air, the altitude of the aircraft and direct parameters of the air. This information is known a...
