Aircraft including a system for measuring pressure, and an associated method

摘要

The invention relates to an aircraft (10) having a system for measuring a static reference pressure in flight, which system comprises:
a pressure sensor (22) connected to the rear portion of the aircraft by a cable (16) and associated with a pressure intake (24) that is located, in flight, in an undisturbed zone downstream from the aircraft, the pressure signal (22) being suitable firstly for measuring a pressure coming from the pressure intake (24) and secondly for transmitting a signal representative of the measured pressure, e.g. an electric signal, to the aircraft; anda system (34) on board the aircraft, which system is suitable for determining a pressure measurement firstly from the transmitted signal and secondly from a position of the pressure sensor (22) relative to the aircraft (10). Pressure is measured dynamically while the aircraft is climbing or descending.

1. An aircraft including a pressure measuring system for measuring pressure in flight, the aircraft pressure measuring system comprising:
at least one pressure sensor located outside of the aircraft, an electric cable by which the at least one pressure sensor is deployably connected to a rear portion of the aircraft, a pressure intake that is located outside of and downstream from the aircraft when the aircraft is in flight and that is in a zone that is not disturbed by turbulent flow created around the aircraft when the aircraft is in flight, the pressure intake being located upstream from said at least one pressure sensor, at least one air feed tube connecting the pressure intake to the pressure sensor, the at least one air feed tube being an air passage that feeds air to the at least one pressure sensor, said at least one pressure sensor being constructed firstly for measuring an air pressure from at least one pressure signal coming from said pressure intake, and secondly for transmitting to the aircraft via the electric cable at least one electric signal representative of the pressure measured by the pressure sensor, a first sensor outside of the aircraft that measures a first position corresponding to the at least one pressure sensor, a second sensor position on-board the aircraft that measures a second position corresponding to the aircraft, and an on-board system located on the aircraft that determines at least one pressure measurement using the at least one sent electric signal and the first position of said at least one pressure sensor relative to the second position of the aircraft.
