The invention is related to a grid type fiber composite structure (1) comprising a grid of polygon cell modules (5) comprising at least three substantially u-shaped ribs made of fiber composite layer (8, 13) and a foam core (9) provided inside each cell module (5) for support of said u-shaped ribs. Said foam core (9) is along a base essentially in line with one of said flat cap sections (11, 12). At least one layer of strip (2, 3) is provided outside said flat cap sections (11, 12) and a skin sheet (4) is unilaterally attached to said cell modules (5) essentially in line with one of said flat cap sections (11, 12). The invention is as well related to a method of manufacturing such a grid type fiber composite structure (1).
摘要:
The invention relates to a compound helicopter (1) comprising a fuselage (2), at least one engine (14) and a main rotor (11) driven by said at least one engine (14). At least one pair of fixed wings are mounted in an essentially horizontal plane on a left hand and a right hand side of the fuselage (2) and horizontally oriented propulsion devices (12, 13) are mounted to each of said fixed wings, said fixed wings encompassing each a drive shaft (16) from said at least one engine (14). Each fixed wing comprises a lower main wing (18) and an upper secondary wing (19) being connected to each other within an interconnection region (22). The propulsion devices (12, 13) are arranged at said interconnection region (22) and said upper secondary wing (19) houses the drive shaft (16) from said at least one engine (14).
摘要:
A method for producing a continuous, three-dimensional, closed semi-finished product made of fiber composite from at least one planar, flat fibrous preform. The method is characterized in that the flat fibrous preform is initially placed flat and aligned to produce a load-bearing fiber orientation and subsequently formed into a three-dimensional structure. In a final step, the three-dimensional structure is then closed to form a closed semi-finished product.
摘要:
A fuselage structure, particularly an aircraft door (1) of composite material comprising at least one panel (2) and at least one beam (3) mounted to each other and the panel (2) with the panel (2) being formed of at least one group of composite layers (5, 6, 20). The at least one beam (3) is provided at least at one of its respective ends (10, 11) with a flange (13) suitable for adhesive engagement with the at least one panel (2). The at least one group of composite layers (5, 6, 20) of the panel (2) is in form locking engagement with this flange (13) of the beam (3).
摘要:
The invention relates to a skid-type landing gear (1) for a helicopter (2) comprising bow shaped crosstubes (10-13) directed symmetrically towards a left- and a right-hand side of a longitudinal mid axis (9) of the helicopter (2) with respective skids (14, 15) at outboard ends thereof and main beams (5-8) in a fuselage (4), the crosstubes (10-13) being connected to the main beams (5-8) via supports (16-23) fixed to the main beams (5-8). The skid-type landing gear (1) is retractable. A method for operating such a skid-type landing gear (1) for a helicopter (2) is provided.
摘要:
An air vehicle with a slip protecting and gas sealing composite floor (1, 10) inside a fuselage, particularly a helicopter with a slip protecting and gas sealing composite floor (1, 10) inside a fuselage. Said slip protecting and gas sealing composite floor (1, 10) is built up of a profiled elastomer layer (2) provided at its bottom side with a cross-linking agent, n-layers (3) of a further component or a variety of different components and partially thermosetting resin covered by a profiled elastomer layer (2), a honey comb layer (4) and lower n-layers (5) of said further component or variety of different components and partially thermosetting resin, said honey comb layer (4) being sandwiched between said n-layers (3) and said lower n-layers (5).
摘要:
A sealing (1) for a fairing (2) against transverse airflow between a wing (3) and a fuselage (4) of an aircraft. Inner and outer sides (7, 8) of the sealing (1) are provided with lips biased against the fairing (2) and the wing (3). At least two gaskets (5, 6) are positioned between respective ends of the sides (7, 8), thus sealing the fairing (2) and the wing (3) against longitudinal airflow.
摘要:
A device for controlling vehicles having a manual control unit configured to influence the direction of movement of a vehicle. The manual control unit provides, in a neutral position of the manual control unit, a trim point to determine a preferred direction of movement. The device further includes a force generating device, generating at least one force acting in the direction of the neutral position of the manual control unit; a trim coupling operable to reduce the at least one force acting on the manual control unit; and a trim control unit configured to store and retain the trim point existing prior to an operation of the trim coupling.
摘要:
A loads interface (1) of an aircraft structure with an edge member (6) and a background structure both preferably made from fiber reinforced plastics. A loads transferring flange (2) is adapted and mounted to said edge member (6) to transmit bending moments into the background structure. Said loads transferring flange (2) is provided with two angled upper and lower planes (8, 9). Said edge member (6) is provided with two angled edge member's upper and lower transfer planes (10, 11). The two angled upper and lower planes (8, 9) and the two angled edge member's upper and lower transfer planes (10, 11) are paired essentially parallel and respectively oriented to each other with an angle of approximately 90° . The invention relates as well to applications of such a loads interface (1).
