Abstract: Apparatus for laminar flow control for a skin panel for an aircraft including a body for receipt into a recess of the skin panel. The body defines a chamber. The body includes an outer portion defining one or more micro apertures through the outer portion, each of the one or more micro apertures being in fluid communication with the chamber. The body includes a support portion supporting the outer portion, the support portion defining at least one outlet for allowing air to be drawn from the chamber in use by a suction means in fluid communication with the outlet in use. The apparatus is arranged such that, in use, air is drawn through the one or more micro apertures into the chamber and out of the outlet, thereby to promote laminar airflow over the outer portion in use.

Abstract: A leading edge skin panel for an aerodynamic structure of an aircraft. The skin panel includes attachment components for attaching the leading edge skin panel to the structure. A primary attachment component is configured to substantially prevent spanwise relative movement between the leading edge skin panel and the structure. The remaining attachment component are configured to permit a predetermined amount of spanwise relative movement between the leading edge skin panel and the structure.

Abstract: An aircraft joint between overlapping first and second components includes a fastener assembly. The fastener assembly includes a threaded fastener and a boss having an outer diameter and a threaded internal bore. The boss is fixedly attached to the second component at the overlap region. The first component has a through hole having a diameter sized to receive the outer diameter of the boss. The boss is received in the through hole from a first side of the first component. The fastener extends through the through hole from a second side of the first component opposite the first side. The fastener is threadably received in the internal bore of the boss and reacts against the second side of the first component to fasten the first component to the second component.

Abstract: A toner cartridge according to one example embodiment includes a housing having a reservoir for containing toner therein. An exit port in fluid communication with the reservoir faces downward on a front of the housing near a first side of the housing. A portion of a main interface gear for providing rotational power to a toner delivery system is exposed on the front of the housing near a top of a second side of the housing and engagable with a corresponding drive gear in the image forming device. A projection projects from the front of the housing and is spaced from the exit port toward the first side of the housing. The projection extends further forward than a frontmost portion of the exit port. A front of the projection is unobstructed for engaging a shutter on a developer unit when the toner cartridge is inserted into the image forming device.
