Definitions
- the present invention relates to the field of aircraft structures. It relates more particularly to the repair of fuselage coatings and substructures in areas highly threatened by impacts. Context of the invention and problems posed
- Aircraft for example of the commercial type and operated by airlines, perform many rotations between various airport platforms around the world.
- the mechanical shock type damage originating from an object outside the aircraft is considered in particular. This may be due in particular to bird shocks or hail damage on the fuselage during the flight, or to vehicle shocks related to ground-based airport operations (landing stairs, tractors, baggage recovery trolleys, etc.). ).
- the Repair Manual contains charts to determine the limits (called “allowable damage limits”) beyond which the dimensions of the damage require repair. It is possible that the proposed standard repairs do not respond, because of their limited size to the degree of damage encountered. The same goes for certain areas of the structure (called reserved areas or “restricted areas” in which no standard solution is proposed, and where any damage must be treated through 'a specific repair plan.
- the Repair Manual is supposed to cover a wide variety of damage situations, which is further enriched over time. Indeed, it incorporates little by little the most frequent damage that the companies have faced or that they have reported.
- this damage coverage by the Repair Manual essentially and uniformly addresses the current areas, excluding certain "reserved areas", or certain excessive sizes of damage.
- the Repair Manual is continually enriched by the manufacturer, according to the life of the devices of a given model.
- a repair out of repair manual can in time be introduced in the Repair Manual if the repair plan is used repetitively, in the same precise location and with the same dimensions of replacement part used.
- a repair plan may never be introduced in the Repair Manual for the sole reason that the damage encountered in the history of the fleet has had a slightly fluctuating size or position, and all the more so since the area is complex, and / or evolutionarily shaped (eg forehead).
- the Repair Manual is particularly well suited to the case of damage occurring systematically in the same place and in a similar way for common areas.
- the objective of the present invention is then to remedy at least some of the problems mentioned above.
- One of the objectives of the invention is thus to reduce the downtime of ground devices during accidental damage repairs occurring on the surface of these devices. Another objective is to minimize the number of repair plans to be made by the manufacturer during the entire life of the fleet (complex area or not).
- Another objective is to reduce the cost of maintenance operations.
- Other objects of the invention are to circumscribe the most endangered areas of the fuselage, and to find for these areas remedies of making available in the most reactive manner possible repair solutions (which will be called "standard” ) physically available in the form of repair kits.
- the invention aims a method of designing repair kits for a predefined area of an aircraft, said repair kits each comprising pieces of shape and dimensions predefined, adapted to be installed within the existing structure, instead of an equivalent form having an accidentally damaged area, which can be deleted or not,
- step 400 comprising a step 400 of creating a range of standardized repair kits optimized to an estimate of the most likely accidental damage in the area studied.
- the originality of the invention is to anticipate the neighboring damage situation in size and position, and to treat such a situation statistically. This replaces a range of repairs created more or less randomly according to the damage notified to the manufacturer and strictly covering one by one, by standard repairs, a little wider, but covering a statistically predetermined part of the damage that may occur in a selected area of the device (and can also cover subsurface replacements - frames, smooth, doublers internal, ).
- the latter further comprises a step 100 of selecting a reference aircraft, equivalent to the aircraft studied, according to a previously defined criterion taking into account, in particular, the service life of the aircraft. aircraft expressed in number of flights and possibly confused with the aircraft studied.
- the method comprises, prior to the step of creating a range of repair kits, a step 300 for identifying the representative accidental damage previously reported on the reference aircraft, in the area studied. .
- the step of identifying accidental damage comprises a sub-step 310 of reporting a statistically significant number of damage, identified in damage records, on a digital model of the area of the aircraft studied.
- the invention consists in making available in the Repair Manual, and from the commissioning of the first aircraft of a fleet, standard repairs whose outline is determined by:
- the damage identification step 300 further comprises a sub-step 330 of trimming in which, for each accidental damage, there is represented an associated "cut-off zone" corresponding substantially to the zone must be repaired during the maintenance operation, cut-off area whose shape contour (rectangular, circular, ...) is chosen according to the type of material forming the local structure of the aircraft. It is understood that the repair does not necessarily imply the replacement of the damaged area, particularly in the case of composite materials, for which glue repairs are possible.
- the method is associated with several simultaneous accidental damage, relating to the same damage sheet, the same cut-off area, if the distance between them is less than a predetermined value, for example less than 1 inter-smooth and less than 1/2 inter-frame.
- the damage identification step 300 further comprises a sub-step 320 of association with at least a portion of the accidental damage carried forward from the plausible cause of each of these damages.
- the damage identification step 300 further comprises a sub-step 340 of extrapolation of the accidental damage of the reference aircraft to a new aircraft.
- step 400 of creating the standardized kit range comprises sub-steps:
- the results (average and variability of the sizes and positions of the cut-out areas) of the sub-step 410 of statistical processing are used to create a first recovery scenario by determining, according to at least a previously defined criterion, the minimum size and superimposition of preformed shape repair zones.
- a sensitivity study is performed, by varying the size of the cut-out areas, either proportionally or by varying only one of dimensions at a time.
- the invention also relates to a method for designing a new aircraft, comprising a phase of definition of the probable damage zones, and a phase of proposing structural modifications in such a way as to reinforce these zones, to facilitate their maintenance or to away from sensitive equipment (such as aerological probes).
- the invention also relates to an aircraft repair manual, comprising standardized repair solutions obtained by a method as described. Brief description of the figures
- FIG. 1 illustrates, in two side views of a fuselage of a reference aircraft, a series of impacts having been recorded on aircraft of this model
- Figure 2 illustrates the method of trimming a real impact
- FIG. 3 schematically illustrates, on an aircraft fuselage viewed from the side, three impact zones identified around an access door,
- FIG. 4 similarly illustrates the impact probability zones identified on a given type of aircraft
- Figure 5 illustrates the principle of 1 scenario envisaged, with ten rectangular repair kits
- Figure 6 illustrates the same principle the 2 nd scenario envisaged, with twenty rectangular repair kits
- Figure 7 illustrates the principle of 1 scenario envisaged, with ten circular repair kits
- Figure 8 illustrates the damage rate taken into account by the repair kits, according to the scenario considered
- Figure 9 illustrates an abacus used for the extrapolation of damage to a new aircraft
- Figures 10a and 10b illustrate the principle of transfer of cut-off areas of damage on the digital model of a new aircraft.
- the invention is intended to be used advantageously during the design phase of a new aircraft. It can however be noted that it can also be implemented after this design, on an existing aircraft and put into service, in a statistically significant number, by air operators.
- the method according to the invention may be preferably implemented, at least for certain steps, in software form.
- Such software is then executed on a computer of the standard type, for example PC type, provided with storage means, calculation, and user and network interfaces known per se.
- This computer is also supposed to have conventional software tools at the level of aircraft manufacturers' design offices, such as database manager, Computer Aided Design (CAD) software, statistical processing software, etc. It advantageously has network access with one or more servers on which geometrical elements of design definition of the aircraft considered.
- CAD Computer Aided Design
- a reference longitudinal axis X of the aircraft corresponding substantially to its axis of displacement of the aircraft is defined.
- a vertical axis Z corresponding to the local vertical is defined.
- the method is implemented, in the present example in no way limiting, for a new aircraft, under development at a manufacturer.
- Step 100 Definition of a Reference Aircraft
- the method for the new aircraft being developed by a manufacturer, said method starts with the definition of at least one "reference aircraft", similar in size, of airports served, but especially objective of lifetime expressed in flights and the type of mission carried out.
- the number of rotations per day performed by the aircraft and the calendar life (of the order of 20 to 25 years) are the key parameters to choose a reference plane.
- the reference airplane for the experience feedback will be another previous generation long-range aircraft, as close as possible to the criteria previous (including but not limited to size, airports served and life in number of flights).
- the reference aircraft is, for example but not necessarily, chosen from the aircraft of the same manufacturer as the new aircraft, for simplicity of access to the maintenance data of the companies operating the aircraft, or access to the data of the aircraft.
- a digital design mock-up is a computer-aided design file of the airplane, with all the geometric and material dimensions defining the parts of the aircraft.
- the method can be implemented on a new aircraft at the beginning of operation, as soon as the number of reported incidents becomes greater than a predetermined threshold, for example several tens in a given area. Knowing that one incident is generally evaluated per year, for a short-haul type device operating ten rotations per day the "normal" rate of damage, the method can be implemented for example as soon as a fleet of some twenty aircraft have been in operation for over a year. Step 200 - Preparing the simplified digital mockup
- the first task aims at simplifying the file of this digital model, for only show in the simplified digital model data used to characterize, in size and position, damage to the coating.
- the data to be kept include:
- any other reference required for the positioning of the damage aerological probes, antennas, etc.
- the richness of the detail of the data stored in the simplified digital mockup can be adjusted in step 300 below, as needed.
- Step 300 Mapping the most frequently damaged areas of damage.
- the method then exploits the "feedback" collected during the operation of the reference aircraft by companies that operate one or more copies of this reference aircraft.
- This feedback comes in the form of damage records, created by each company to describe a damage found on a device, and stored in an appropriate database (analog or digital).
- Each damage is described in a report made by a company operating a copy of the reference aircraft, and recorded in a database, each event being stored in the form of an injury file.
- SRM + excluding SRM exhaustive data
- damage data relating to the reference aircraft are considered insufficient in number (for example less than a few hundred), they can be supplemented with damage data collected on another reference aircraft, a little further from the new aircraft according to the selection criteria mentioned in step 100.
- the task consists in a first sub-step 310 to report the damage data on the simplified digital model of the reference aircraft.
- a reporter on the digital mockup By means of a reporter on the digital mockup, the fact of locating the damage data, reported by the companies, according to the axes of the simplified digital model, in a manner consistent with the scale of the airplane, and memorizing them in this model simplified digital.
- Figure 1 illustrates an aircraft fuselage front
- Such an allocation can be carried out in an automated manner, for example by using a principal component analysis algorithm of a damage database characterized by their position in an aircraft coordinate system (for example a reference linked to a passenger door angle ), their dimensions, their type of form, their intensity.
- a principal component analysis algorithm of a damage database characterized by their position in an aircraft coordinate system (for example a reference linked to a passenger door angle ), their dimensions, their type of form, their intensity.
- Such an algorithm will bring out in the same cloud of points damages of the same form, energy and position, probably attributable to the same cause, and leave aside data, possibly in the same area on the aircraft, but of different intensity or shape (or any combination of factors).
- the knowledge of the cause makes it possible to determine the mode of extrapolation of the position of the impact between the reference plane and the new airplane.
- the relative positioning of a fixed-size airport vehicle with respect to an objective contact point causes, in a statistical manner, distant damage. of this point of contact according to a probabilistic law whose parameters (for example, average and standard deviation) are related to the dimensions of the airport vehicle, but whose position on the new aircraft remains identical with respect to the target contact point (door angle for example).
- a phase of explanation of the causes of at least a part of the damage can therefore make it possible to improve the prediction of damage on a new aircraft.
- the present description is mainly concerned, in the present example of implementation, with the statistical distribution of the positions of the damage and their characteristics, for example dimensions and intensity.
- the intensity of each damage is therefore also reported on the simplified digital model of the reference aircraft. This intensity serves, for for example, to extrapolate a metal airplane to a composite fuselage airplane.
- a sub-step 330 for each damage reported by a company in a damage file, it represents (FIG. 2) first its actual reported contour, then its approximate contour, in the form of an ellipse, and a "zone". cut off 'associated. It is understood that the cut-off area corresponds substantially to the area to be replaced during the repair operation consequent to the damage.
- the cut-off area is a first treatment of the damaged area.
- the outlines of the cut-out area are, in the present example, parallel to the adjacent substructure elements (smooth and frames for example).
- the cut-off area may, however, be circular in shape (which is desirable for aircraft using composite "CFRP" coatings for bonded repairs), or any other form, which might be considered suitable for repair.
- a cut-off area may include several damages relating to the same sheet, that is to say associated with the same impact event, according to a simple criterion: if they are, for example, distant from each other by less than one inter-smooth and less than 1/2 inter-frame (or any other previously selected distance threshold).
- a total of several hundred elementary damage records should preferably be processed in this step 300 of damage reports. This number is considered sufficient to guarantee that the sample thus created is significant, thus allowing the necessary statistical treatment in the synthesis step 400.
- the damage data, created during this step 300, are then transferred to the digital model of the new aircraft, during an extrapolation of the damage observed on the reference aircraft, in damage. plausible on the new plane.
- the digital model of the latter is therefore preferably developed with the same digital drawing software as the digital model of the reference aircraft.
- the positioning of the damage is thus kept constant with respect to the threshold and the front frame of the door, which serve as a fixed reference point for the two digital models.
- This provision allows to take as a reference, the target commonly used by an operator responsible for approaching a vehicle of the aircraft during ground operations on an airport platform for example.
- contours of the damage and the associated cut areas can be amplified in size around their center, by means of a previously determined coefficient corresponding, for example, to a difference in coating material between the new aircraft and the airplane. reference, but also other local characteristics, geometric for example, the impacted structure (thicknesses, distance to the frames, ).
- the correction charts are established on the basis of models calibrated by representative test-tube tests.
- a damage defined by its dimensions
- a size correction chart previously created, using as input the local characteristics of the reference structure and new, allows to determine the correction coefficient of the size of the cut-off area to extrapolate the damage to another structure at substantially unchanged.
- Such an abacus can be created in a manner known per se. An example of an abacus is given by way of illustration in FIG. 9.
- This arrangement thus makes it possible to take into account a greater sensitivity of the coating material (for example carbon fiber reinforced plastic or CFRP "Carbon Fiber Reinforced Plastic” in the Anglo-Saxon language).
- the coating material for example carbon fiber reinforced plastic or CFRP "Carbon Fiber Reinforced Plastic” in the Anglo-Saxon language.
- the damage is all transferred to the digital model of the new aircraft, and it calculates on this model which damage is admissible, knowing their intensity and the nature of the local substructure (thicknesses, distance to the frames, material, reinforcements ). This allowable damage on the new aircraft can then be excluded from the definition of standard repairs.
- FIG. 10a reference aircraft
- FIG. 10b shows a contour 11 of an aircraft passenger door, a service vehicle stowage target 12, the external surface 13 of the reference aircraft, a cut-off area 14 corresponding to a damage (with its size and position relative to the target 12), the direction of movement of the vehicle, and a volume called "extruded" 16 created from the cut-off area, according to the direction 15 of movement of the vehicle.
- FIG. 10b similarly illustrates, but for a new aircraft, the outline 11 of a corresponding aircraft passenger door at the same door of the reference aircraft, a new service vehicle stowage target 18, the outer surface 17 of the new aircraft, and the direction 15, supposed identical, the vehicle movement.
- the transfer then consists of recalculating the interception of the damage trace in "extruded” form 19, previously corrected with the external surface 17 of the new aircraft. It has been seen above that this correction is carried out using coefficients summarized on an abacus, and intended to take into account the variations of materials and local characteristics of the different structure.
- the axis of damage in "extruded” form 19 is parallel to the vector 15 of displacement of the vehicle having caused the damage. From this is deduced the new cut-off zone 20 of the damage on the new aircraft, at the same position relative to the lashing target.
- this step can be performed automatically, from a database.
- This step of synthesis of the data on the digital model of the new aircraft comprises three sub-steps:
- a statistical processing 410 (illustrated schematically in FIG. 3) makes it possible, initially, to characterize the plausible damages, as extrapolated on the digital model of the new aircraft (following the extrapolation performed in the previous step 300), in terms of size distribution, and positions of the cut areas.
- FIG. 3 there is the aircraft fuselage 1 in the left view, with the windshield 2 and a passenger side door 3g.
- the concentrated damages around the door are here represented by their cut-out areas 7.
- Statistical distribution law profiles in the vertical and longitudinal directions are illustrated, both for the lower part of the door (curve 8), and for the profile of the door. vertical position (curve 9) and longitudinal position (curve 10).
- the results obtained guide the second sub-step 420, by determining the minimum size and superimposition of the repair zones.
- Typical areas are defined, characterizing envelopes containing a given percentage of plausible damage, as shown in Figure 4, which illustrates areas 1 1, 12, 13 containing respectively 90%, 95% and 99% of probable damage in the vicinity of the door of the new aircraft studied.
- each zone is also characterized. This characterization consists of first ensuring the statistical homogeneity of the area, variability of both the positions and sizes of the damage as well as the impact intensities, as well as the natures and causes of damage.
- repair means the replacement part of an area of the aircraft liner, possibly including part of the substructure
- repair means the replacement part of an area of the aircraft liner, possibly including part of the substructure
- two scenarios are envisaged.
- the second scenario ( Figure 6) a small number of major repairs.
- a sensitivity study (FIG. 8) is performed, by varying the size of the cut-out areas, either proportionally or by varying only one of the dimensions at a time.
- This study determines how much damage can be repaired, with a set of ten standard repairs, or with a set of twenty standard repairs, depending on the average repair size.
- a major advantage of the invention is apparent from the comparison of the prior art and the method according to the invention. Indeed, a deficiency of the method used in the prior art is that statistically highly exposed areas, such as the vicinity of the doors (passengers, service, cargo) are insufficiently covered, which generates a significant economic impact for the companies and the insurance.
- a permanent repair requiring a complete cycle (definition, calculation, approval and manufacture of parts) represents a period of one to two months, but a temporary repair is then put in place on the damaged area, so as not to immobilize the aircraft during these two months.
- This temporary repair requires a cycle of one week.
- the difference on immobilization is therefore of the order of five days per repair, but quite often in the case of door corners, the repair is so complex that one immediately enters the category of permanent repair.
- Another advantage of the method as described is that, in a situation of damage around doors for example, the company operating the aircraft no longer has to turn to the manufacturer. This avoids the need for a lengthy mail exchange process (to determine and then confirm the extent of damage), plan development, repair calculation, and finally approval of the repair, because solution then exists in the Repair Manual.
- Repair kits are also made available and cover a specific fraction of the cases that will be encountered in the life of the aircraft.
- the implementation of this method also avoids the double repair (temporary repair to put the aircraft back into service until a scheduled immobilization - great visit, for example - then permanent repair).
- the repair can be repeated several times (change to a repair size and / or a larger fastener diameter) if the same area is repeatedly impacted during the life cycle of the aircraft.
- the standard repair can be significantly larger than the damage, its implementation is slightly longer (eg an hour or two), but this extra time remains of secondary importance compared to the fact of not having to immobilize the aircraft as long as in the prior art (several days or even a week).
- the damage transfer phase 300 also includes a substep of statistical analysis of the damage zones listed on the reference aircraft, and reported on its simplified digital model. Such an analysis is intended to automatically assign damage to predefined causes. For example, such a statistical analysis, of a type known per se, can highlight damage zones at a distance of about the width of a boarding bridge.
- the extrapolated damage zones will also remain distant on the new aircraft, regardless of its own dimensions.
- damage related to the opening of the passenger door itself have a probable area of size proportional to the size of this door on the new aircraft.
- it comprises a step 500 of proposing modifications of the structure of the aircraft, when the latter is in the development phase.
- This variant is conceivable in the case where the method of defining areas of probable damage is integrated into the design process of a new aircraft. It is then deduced from the implementation of the method of determining areas of probable damage, modifications of aircraft structures, in particular to strengthen these areas, to facilitate maintenance, for example by ensuring the possible integration of a repair in a congested area, or to move sensitive equipment away from endangered areas. In other words, we make sure from the design of the aircraft to strengthen it where it will most likely be struck, and make it easily repairable in these places.
