Die Dauerfestigkeit eines Bolzens zum Verbinden eines Startgerätes für Flugkörper mit dem Pylon eines Trägerflugzeuges soll durch Verminderung der inneren und äußeren Kerbwirkung erhöht werden. Der Bolzen ist mit einem Kopf (10) versehen, der von einem scheibenförmigen Abschnitt (12) größeren Durchmessers und einem daran anschließenden zylindrischen Abschnitt (14) geringeren Durchmessers gebildet ist, und mit einem Schaft (16) mit einem glatt zylindrischen Abschnitt (18) und einem daran anschließenden Gewindeabschnitt (20). Der Bolzen ist ein Schmiedestück aus einem wärmebehandelten höchstfestem Chrom-Molybdän-Vansdin-Stahl mit 0,4 C, 5 Cr, 1,3 Mo und 0,5 V, der nach der Wärmebehandlung ein feinkörniges Vergütungsgefüge ohne Seigerungszonen besitzt. Die Oberfläche ist in einer eine Wasserstoffversprödung ausschließenden Weise behandelt. Die Krümmungsradien von Innenkanten sind größer als 0,6 mm. Das Gewinde und der Schafteinstich des Bolzens sind gerollt. Der Kopf (10) des Bolzens weist einen gestauchten Innensechskant (26) auf.
摘要:
A reconfigurable unmanned aircraft system is disclosed. A system and method for configuring a reconfigurable unmanned aircraft and system and method for operation and management of a reconfigurable unmanned aircraft in an airspace are also disclosed. The aircraft is selectively reconfigurable to modify flight characteristics. The aircraft comprises a set of rotors. The position of at least one rotor relative to the base can be modified by at least one of translation of the rotor relative to the boom, pivoting of the boom relative to the base, and translation of the boom relative to the base; so that flight characteristics can be modified by configuration of position of at least one rotor relative to the base. A method of configuring an aircraft having a set of rotors on a mission to carry a payload comprises the steps of determining properties of the payload including at least mass properties, determining the manner in which the payload will be coupled to the aircraft, determining configuration for each of the rotors in the set of rotors at least partially in consideration of the properties of the payload, and positioning the set of rotors in the configuration for the aircraft to perform the mission.

On utilise, pour la mise en opération du module d'instrument aéroporté récupérable (100), une cellule d'avion (301) à aile en delta pourvue d'un gouvernail (310) pouvant être commandé. Le module d'instrument récupérable (301) est emporté dans les airs par un ballon (102) afin de permettre à sa charge utile, comprenant l'ensemble d'instruments, d'effectuer une série de mesures météorologiques. Un circuit de navigation (211, 212), contenu dans la cellule, consulte les transmissions en radiofréquence d'une multiplicité de balises pour déterminer l'altitude et la position géographique du groupe d'instruments (100). Ces informations, ainsi que des données identifiant la position d'au moins un site d'atterrissage prédéterminé, sont utilisées pour calculer de manière dynamique une trajectoire de vol. Le circuit de contrôle de guidage (213, 506) utilise le gouvernail (310) pour diriger le module récupérable (100) en un vol plané le long de la trajectoire de vol calculée vers le site d'atterrissage choisi. Un émetteur en radiofréquence (203, 204) diffuse des informations concernant la présente position du module qui fonctionnent comme des balises permettant de récupérer plus rapidement le module (100).
摘要:
An apparatus and method for attachment of a payload or store to the external surface of an aerial vehicle includes a single point release feature. The apparatus includes an elongated base having a first distal end and a second distal end. A retention receptacle including a hollow tube is disposed adjacent the first distal end and is configured to removably receive and retain the store or payload. In addition, a release receptacle housing a release mechanism assembly is disposed adjacent said second distal end. When the release mechanism assembly is in the closed and locked position, the store or payload is retained to the vehicle via a spring loaded lock pin advanced into the retention receptacle. When the release mechanism assembly is in the open and unlocked position, the store or payload may be disengaged from the vehicle.

Examples disclosed herein generally relate to a pass-through bulkhead seal fitting for use in the aircraft industry. In one example, a pass-through bulkhead seal fitting includes a male fitting comprising a tubular body that is separable to receive existing wiring, and a nut that is separable to receive existing wiring and being rotatable in a single direction relative to a longitudinal axis of the male fitting.

Dispositif de largage d'une charge. Il comprend un crochet (5) de maintien de la charge (2) sur son support, des moyens pour déverrouiller le crochet au moment de la séparation de la charge de son support et est caractérisé en ce que le crochet coopère avec au moins un organe mobile de verrouillage (9) de ladite charge et avec des moyens pour maintenir le crochet dans la position de verrouillage tant qu'il n'est pas sollicité vers la position déverrouillée. Application notamment à un verrouillage d'une bouée d'écoute.
摘要:
One aspect of the present invention involves a hold-down and release mechanism ("HDRM") that includes a hold-then-release mechanism configured to hold an element until the hold-then-release mechanism is commanded to release the element; and an integral sensor configured to sense an amount of a parameter of interest associated with the HDRM and to communicate the sensed amount of the parameter of interest to a receiving device. The parameter of interest comprises one of tensile preload, temperature, vibration, shock, and time from application of an HDRM firing current to HDRM release of the element.
