Abstract:
A heavy truck frame (18) and a method for manufacturing a heavy truck frame having side-rails (20, 24) with a configuration of a top C-section (30) and a bottom C-section (32) and a vertical insert (34) so as to reduce weight and maintain the stiffness requirements and improve payload. The optimal distances between a top C-section (30) and a bottom C-section (32) can vary according to the part of the frame and vehicle requirements.
Abstract:
Method and apparatus for assembling, with fasteners, components of a structure having an outboard side, an inboard side, and a supporting frame. An electromagnet (200) having a core (202) with multiple openings (210) is positioned on the outboard side. A magnetically attractive member (400) is placed against the inboard side opposite and aligned with the electromagnet (200). When activated, the electromagnet (200) is attracted towards the magnetically attractive member (400) and the two hold the components together. Multiple drill members (316) pass through the openings in the core of the electromagnet and multiple openings are drilled simultaneously through the components. Subsequently, multiple rivets or huck bolts are simultaneously inserted into the drilled openings. Finally, fasteners are hammered through the drilled openings and rivets are secured by bucking bars provided on the magnetically attractive member. Alternatively, openings are provided in the magnetically attractive member for manually securing huck bolts to the components.
Abstract:
A crash box includes a body portion extending from a top edge to a bottom edge along a global z-axis (A) and having a pair of side walls disposed in spaced relationship to one another. At least one x- shaped reinforcing web extends between the side walls along a plane (P) disposed transverse to the axis (A). An extension portion is integral with the body portion and extends outwardly from one of the side walls and is disposed along the plane (P). A flange plate is also integral with the body portion and defines at least one flange plate attachment hole for securing the crash box to a frame of a vehicle.
Abstract:
A system for attaching an aircraft wall panel to an airframe member includes a top support bracket (310) having a mating member (335), a lower support bracket (415) having a mating pin (436), and an aircraft wall panel having a first stabilizing attachment (302) and a first securing attachment (603). The first stabilizing and securing attachments (302, 603) are arranged on a rear surface of the aircraft wall panel. The first stabilizing attachment (302) is configured to connect to the mating member (335) of the top support bracket (310) and retain the aircraft wall panel in proximity to the airframe member. The first securing attachment (603) is configured to connect to the mating pin (436) of the lower support bracket (415) to (a) engage the lower support bracket (415) and facilitate horizontal and vertical adjustments of the aircraft wall panel in relation to the airframe member, and (b) lock a position of the first securing attachment (603) relative to the lower support bracket (415).
Abstract:

Abstract:
The present invention provides an aircraft structure comprising a first sub-structure (110), having a first box cross-section, a second sub-structure (120), having a second box cross-section, and a joint joining a first end region of the first sub-structure to second end region of the second sub-structure, wherein the joint comprises an overlap region where the end regions of the first and the second sub¬ structures overlap such that the first sub-structure (110) is inside the second sub-structure (120). The present invention also provides an aircraft comprising such an aircraft structure and a method of manufacturing an aircraft structure.
Abstract:
A single, common, fuselage and wing design of an aircraft structure provides for two different aircraft models or configurations. A fuselage (12) has a center section cutout area (212). Each wing (16) has an airfoil over substantially its entire span. In one configuration (2A), a center section component (212), such as a wingbox, is inserted into the center section cutout and the wings are connected to opposing sides of the center section component by a side-of-body join. In another configuration (2B), the wings are moved inwardly, joined to the fuselage, and also joined to each other in a centerline join at the centerline (218) of the aircraft wherein a portion (16A) of the airfoil of each wing is then inside the fuselage. Different flaps (210, 220), spacers (222), and/or different engine mount locations (402, 404) may be provided for the wings for the two configurations.
