Definitions
- the invention relates to the field of aeronautics. More specifically, the invention relates to the detection of impacts received by the fuselage of an aircraft and the optimization of the operation of an aircraft on the ground.
- the present invention falls within this context, and aims to meet this need.
- the subject of the invention is an onboard system for detecting impacts on the fuselage of an aircraft, comprising: a. a plurality of impact sensors arranged on a plurality of zones of the fuselage, each sensor being capable of detecting an impact on the fuselage at its position, b. a module for detecting a vehicle in the vicinity of the aircraft, the detection module being capable of estimating the speed of a detected vehicle, and c. a computer arranged to, upon detection of an impact on the fuselage by an impact sensor, record in a memory of the on-board system information relating to the speed of a vehicle detected by the detection module.

- a detection module also on board the aircraft makes it possible to identify the vehicles circulating around the aircraft, which are moving away from it and/or which are approaching it, and therefore to detect, also almost instantaneously, the vehicle responsible for this impact. The estimation of its speed then makes it possible to determine its responsibility in this shock and possibly to qualify or confirm the amplitude of the shock estimated by the impact sensors. In this way, an anomaly report can then be transmitted to the company operating the vehicle.
- the fact that the entire system is on board the aircraft allows the company operating this aircraft to obtain all of this information in real time, without having to go through a sur external surveillance managed by the company operating the airport where this aircraft is stationed.
- the computer is arranged to record in said memory, the position of said detected impact, estimated by means of an identifier of said impact sensor having detected an impact, the positions of each of the impact sensors on the fuselage being pre-finished.

- the computer is arranged to, upon detection of an impact on the fuselage by an impact sensor, trigger the detection of a vehicle in the vicinity of the aircraft by the detection module and the estimation of the speed of said detected vehicle.
- the detection module is the detection of an impact by one of the impact sensors which “wakes up” the detection module in order to identify the vehicle responsible for the impact and to estimate its speed. This optimizes the electrical consumption of the system.
- the detection module can be arranged to identify in real time and permanently all the vehicles circulating around the aircraft, and the computer can be arranged to, when detecting an impact on the fuselage by an impact sensor, requesting identification by the detection module of a vehicle in the vicinity of the position of said impact sensor having detected an impact, in particular at a preceding instant and/or following the detection of said impact.
- each impact sensor is able to estimate the power of an impact that it detects and to send information relating to this power to the computer, the system being arranged to send an alarm signal to destination of a remote electronic system if the estimated power of said impact is greater than a predetermined threshold.
- the system can be equipped with a communication module wireless capable of transmitting said alarm signal to said remote electronic system. According to this characteristic, it is thus possible to trigger an intervention for maintenance and/or repair operations in a minimum time.
- each impact sensor is a sensor of the piezoelectric type, of the piezoresistive type or of the capacitive type.
- each sensor comprises a test body; an electrically insulating substrate; a first electrode bonded to the substrate; a second electrode; a set of conductive or semi-conductive nanoparticles in contact with the two electrodes; a measuring device delivering information proportional to an electrical property of the assembly of nanoparticles, which property is measured between the first and the second electrode, said electrical property being sensitive to the distance between the nanoparticles of the assembly.
- the test body can be constituted by the assembly of nanoparticles itself.
- an “assembly of nanoparticles” consists of one or more sets of nanoparticles linked together by a ligand (or ligand) within each set, said sets being linked together electrically.
- the nanoparticles are gold nanoparticles.
- the ligand can be a sodium citrate or an alkylamine.
- proportional information is meant a measurement which varies with the measured property, the proportionality function possibly being linear, exponential or of any other mathematical form establishing a one-to-one relationship between the value of the measurement and the value of the measured property.
- the electrical property measured can be the resistance of the assembly of nanoparticles, or else the electrical capacitance of the assembly of nanoparticles.
- the second electrode is remote from the first electrode and can be mobile with respect to the substrate and the assembly of nanoparticles can be placed between the two electrodes in such a way that a movement of the second electrode causes a modification of the distance between the nanoparticles of said assembly of nanoparticles.

If necessary, the fields of view of the two cameras may partially overlap. For example, the position of said vehicle at a given instant can be estimated from two images acquired at said instant by each of the cameras, in particular by stereoscopy, and the speed of said vehicle can be estimated from the position of said vehicle estimated at two instants distinct, for example by integrating the position of said vehicle over time.
