Definitions
- the present invention relates to a new design of aircraft frames made of composite material, in particular for integral fuselages in one piece, as well as to a method for obtaining them.
- the fuselage is the main set of an aircraft, since the rest of the elements that make up the aircraft are attached, directly or indirectly, to it.
- the lining of the fuselage is what gives it its shape, which varies with the main mission that the aircraft will have.
- the fuselage of an aircraft comprises elements in the form of perpendicular reinforcements with respect to the longitudinal axis of the aircraft, called frames (of CFRP or metallic, with a C-shape) , Z, etc.), which are responsible for giving shape and rigidity to the fuselage structure, these frames being located at determined intervals inside the fuselage of the aircraft.
- the fuselage comprises other reinforcement elements, such as the stringers (generally in the form of omega, T or similar) to achieve optimization of load distribution and stiffness. The stringers are placed longitudinally on the fuselage lining, allowing its optimization, thus lightening the weight of the whole structure.
- the fuselage of an aircraft was performed in a segmented manner, so that the lining was made up of several panels and sections that subsequently joined to form the typical fuselage in a cylindrical shape.
- the joints between these segments or panels are made by means of a series of connecting pieces designed for this purpose, which were generally joined by rivets.
- the frames in the case of such fuselages were generally arranged in a segmented manner, such that they were placed and adjusted manually on the previous structure. This procedure of composition and placement of the frames is easy to assemble, as the parts that make up the lining of the fuselage are open inside, so that it allows a simple and correct adjustment of the frames, by segments.
- the lining that forms the fuselage of an aircraft integrally called a fuselage in 360 °, full-barrel or one-shot.
- the lining that forms the fuselage integrally forms in a single closed piece made in a single mold.
- the present invention offers a solution to the aforementioned limitations.
- the present invention relates to a new design of aircraft frames made of composite material, said frames being made in partitions or segments of determined length that will be arranged on the inner part of the lining that forms the fuselage of The aircraft.
- the fuselage will be made integrally in one piece (called full-barrel or one-shot fuselage), this fuselage being able to comprise integrated stringers from the same manufacturing process of said fuselage.
- the length of the partitions or segments of said frames will be the maximum possible (which will lead to the minimum number of partitions per section diameter of the fuselage) such that the maximum separation between these segments of frames and the lining, this separation being measured by the inner part of said coating, allows the use of a liquid sealant for joining the segment of the frame to the coating.
- the use of this type of sealant simplifies operations and reduces assembly times, which allows to reduce recurring costs for this concept.
- the maximum length of the frame segments shall be calculated based on the manufacturing limitations given by the manufacturing tolerances of the lining and of the frame segments themselves.
- the invention relates to a method for obtaining this design of cited aircraft frames, said frames being made of composite material, and comprising partitions or segments of determined length, such that said segments of calculated frames maintain a maximum separation with respect to the interior of the lining that is such that it allows the use of a liquid sealant for joining the segment of the frame to the lining that forms the fuselage.
- the method of the invention comprises the following steps:
- step b) determination of the contact point of the type frame segment with the inside of the lining as a result of step a); c) determining the points of the frame segment, on both sides of the previous contact point, in which the maximum separation between said frame segment and the inner part of the coating is the maximum allowed for the use of a liquid type sealant ;
- step f) determination of the contact points of the type frame segment with the interior of the lining as a result of step f);
- Figure 1 shows in section a detail of the fuselage of an aircraft comprising an aircraft frame design according to the present invention.
- Figure 2 shows in section the tolerances that are taken into account for the design of the aircraft frame according to the present invention.
- Figure 3 shows in section the case in which the manufacturing tolerances that are taken into account for the design of the aircraft frame according to the method of the present invention converge such that the manufactured frame is smaller than the nominal value provided for the same, being the lining of the fuselage manufactured of greater size and of smaller thickness than their respective nominal expected.
- Figure 4 shows in section the case in which the manufacturing tolerances that are taken into account for the design of the aircraft frame according to the method of the present invention converge such that the manufactured frame is larger than the nominal value provided for the same, being the lining of the fuselage manufactured of smaller size and of greater thickness than their respective nominal expected.
- the present invention relates to the new design of aircraft frames made of composite material, said frames being made in partitions or segments 1 of determined length 2 that will be arranged on the inner part of the lining 3 that forms the fuselage of the aircraft, said fuselage being made integrally in a single piece, (called full-barrel or one-shot fuselage), such that the length 2 of the partitions or segments 1 of said frames is the maximum possible (which will lead to minimum number of partitions 1 per section diameter of the fuselage) such that the maximum separation 5 between the section 1 of the frame and the lining 3, measuring this distance or separation 5 by the inside of the fuselage is less than the limit allowed for the application of a liquid sealant, said maximum separation having been calculated based on the manufacturing limitations given by the fabric tolerances ation of the lining 3 and the frames.
- the maximum separation value 5 for the application of a liquid sealant is about 0.5 mm. Above this separation value 5, another type of sealant (typically solid sealant) must be applied which
- section 1 of the frame is arranged, avoiding It is possible to partition or section 1 of the frame in an area or section of the fuselage that is subject to a very high load.
- the length 2 of the section 1 of the frame will be such that the smallest possible number of sections 1 or partitions 20 is obtained, that is, the length 2 will be the maximum possible.
- savings are achieved in parts and joining elements used in traditional designs, as well as in the assembly time, by avoiding the use of sealants in solid state, which leads to savings in time and labor of assembly, avoiding problems in the operation of riveting, without this leading to a loss of mechanical characteristics of the joint.
- the manufacturing tolerances of the coating 3 (aerodynamic tolerance that makes the coating 3 have an effective external value of 1 1 and tolerance of the thickness of the coating 3 which makes the coating 3 have an effective internal value of 12) and of section 1 of the frame (manufacturing tolerance of section 1 of the frame that causes the said frame to have an effective external value of 13), as well as the limitations imposed by the maximum allowable separation in mounting below which it is possible Applying liquid sealant, the number and optimal position of sections 1 of the frame of the invention are defined, that is, the number of partitions 20 of which the entire frame of the invention is composed.
- the coating 3 is of maximum size, as the aerodynamic tolerance of the same maximum (effective external value 1 1 is maximum) and its tolerance of minimum thickness (internal effective value 12 is maximum);
- the lining 3 is of minimum size, since the aerodynamic tolerance of the same minimum (external effective value 1 1 is minimum) and its maximum thickness tolerance (internal effective value 12 is minimum);
- the maximum separation 5 between the lining 3 and the section 1 of the frame appears, for the case of fuselage of cylindrical geometry, in an area 7 close to the center of the section 1 of the frame ( Figure 4).
- the maximum separation 5 is systematically calculated for each possible section 1 of notebook, according to the invention.
- the invention develops a method for obtaining aircraft frames made of composite material, said frames being made in partitions or segments 1 of determined length 2 that will be arranged on the inner part of the lining 3 that forms the fuselage of The aircraft.
- the method of the invention comprises the following steps:
- step a) determination of the contact point of segment 1 of type frame with the interior of the lining 3, as a result of step a);
- step f determination of the contact points of segment 1 of the type frame with the interior of the lining 3, as a result of step f);
- the fuselage of the aircraft and, therefore, the lining that forms the same can have a cylindrical section, or a conical section. In addition, they may have certain section changes along their length, depending on the longitudinal axis of the aircraft. In any of these cases, the method of the invention and the design of frames obtained therewith, are perfectly valid.
- the points at which it occurs that the maximum separation 5 between the lining 3 and the segment 1 of the frame is such that It allows the use of a liquid type sealant, they are located at the ends 6 of the segment 1 of the calculated frame.
- the point at which the maximum separation 5 between the cladding 3 and the section 1 of the frame appears is in an area 7 close to the center of the section 1 of the frame.
