La présente invention propose un pilotage de secours d'une chaîne de commande de vol manuelle (7) d'aéronef (1). Une transmission terminale mécanique (23) comporte vers l'aval, au moins un vérin série (21) en parallèle d'au moins une bielle de centrage (22). En cas de rupture d'un moyen flexible de liaison (26), un dispositif de commande (8) en amont prend une autorité sur l'agencement électronique de contrôle (29) du vérin série (21), tandis qu'un quadrant pivotant de sortie (25) est soumis par ladite bielle de centrage (22) à une action de blocage et centrage. En cas de rupture de chaîne, ce quadrant pivotant de sortie (25) forme un appui pour le vérin série (21), et un pilotage de secours est transmis depuis un dispositif de commande vers l'agencement électronique de contrôle (29), de manière à actionner la surface aérodynamique (11) en aval.
摘要:
The invention relates to a structure (10) for aircrafts, characterised in that it comprises a part (20) comprising a metal leading edge (30), said leading edge (30) being covered by a coating (40) having a thickness which is less than or equal to ten micrometres and having a hardness higher than six hundred in the Vickers hardness test (HV). According to a mode of embodiment, said coating (40) is a multilayer stainless steel coating consisting of a superposition of layers with a low nitrogen gradient and layers with a high nitrogen gradient, said layers having a thickness essentially equal to a micrometre. The invention also relates to an aircraft comprising such a structure.
摘要:
In an aircraft (1), a distributed architecture compliant to the specification ARINC653 forms a DIMA (3) with Partitions (5) in hardware Modules (6), where shared memories (13) are mapped with shared I/O memory (11). For detecting / treating errors at various Levels in the DIMA (3) a superintending RTOS extension of existing Health Monitor Units (HMU) in the Modules (6) is run as a Health Monitor Supervisor (HMS). The invention allows communicating all the existing Health Monitor Units (HMU), thus providing global errors visibility, shared recovery actions and smooth fault treatment.
摘要:
In an aircraft (1), a distributed architecture compliant to the specification ARINC653 forms an IMA (3) with Partitions (5) in hardware Modules (6), where shared memories (13) are mapped with shared I/O memory (20). For flexible communication among Partitions (5), a circular buffer (19) and a concurrent programming algorithm (23) are coupled to each shared I/O memory (20). A Publisher Component (16) builds new messages with datum and topics (21). A Subscriber Component (17) goes through a local message buffer searching for those ones matching a topic (21). A selective communication is performed by elected areas of the shared I/O memory (20). Finally are set as read previously delivered messages in order to prevent duplicated readings. The invention is distinct from data transfer via classical channels, thus being useful to obtain high reusability, portability and scalability.
摘要:
The invention is related to a heat control system for an adaptive consolidation roller (8) for the production of consolidated layers (2) made of fiber reinforced polymers comprising the adaptive consolidation roller (8) for applying, on an application surface (3), a band (4) formed of at least one resin preimpregnated flat tape (5), and a heating system (6, 7) adapted to emit heat radiation directed towards the band (4). Said adaptive consolidation roller (8) is rotatable on a spindle (9) and comprises a surface made of an elastic deformable, flexible material. At least one additional roller (10) with thermal control means is provided and said at least one additional roller (10) is pressed from radial outside against the surface of the adaptive consolidation roller (8).
摘要:
La présente invention concerne un procédé d'assistance d'un pilote d'un aéronef (1) monomoteur à voilure tournante lors d'une phase de vol en autorotation, ledit aéronef (1) comportant une installation motrice hybride munie d'un moteur thermique (13), d'une machine électrique (12) et d'une boîte de transmission principale de puissance (11). Ledit aéronef (1) comporte également un moyen de stockage (14) d'énergie électrique et un rotor principal (2) lié mécaniquement à ladite installation motrice hybride (5). Selon ledit procédé, on surveille pendant un vol le fonctionnement dudit moteur thermique (13) afin de détecter une panne de celui-ci notamment par l'intermédiaire d'une chute de puissance sur ledit rotor principal (2), puis lorsqu'une panne dudit moteur thermique (13) est détectée, on commande ladite machine électrique (12) pour fournir une puissance auxiliaire W e audit rotor principal (2), permettant ainsi d'assister un pilote dudit aéronef (1) pour manoeuvrer ledit aéronef (1) lors de ladite phase de vol en autorotation consécutive à ladite panne.
