Modular partitioning device intended for an aircraft

Abstract: This adjustable partitioning mechanism for an aircraft comprises a more or less straight upper rod (34) of variable length and assumed to be horizontal. The rod (34) comprises at its ends connection means allowing the rod (34) to pivot around a vertical axis. The mechanism further comprises a curtain (36) having attachment means intended to cooperate with complementary attachment means mounted on the rod (34). The invention also relates to an aircraft equipped with at least one such partitioning mechanism.

Cross-bleed dam

Abstract: A panel assembly for an aircraft including a panel having an upper aerodynamic surface and a leading edge, and a hinge fitting connected to an underside of the panel, defining a hinge line for the direction of rotation of the panel. The upper surface of the leading edge has an arcuate portion centered about the hinge line, and has an upturned portion forward of the arcuate portion. The panel assembly is pivotally connected to its hinge fitting to the trailing edge of the fixed wing portion and rotatable between a first position wherein the upper surfaces of the fixed wing portion and the panel are substantially flush, and a second position wherein the panel is rotated downwardly from the first position. A seal member attached to the trailing edge of the fixed wing portion, has a lower surface which seals against the upper surface of the panel during its movement.

Flow body having a leading edge, a surface and an active flow control system and vehicle comprising at least one such flow body and an air source

Abstract: A flow body having a surface, a leading edge has an active flow control system. The active flow control system includes a plurality of openings, at least one control pressure varying device and at least one fluidic actuator with an interaction chamber having an inlet connectable to an air source, at least two outlets and at least two control pressure ports. The openings are distributed along or parallel to the leading edge in a side-by-side relationship and extend through the surface. The control pressure varying device is connected to the at least two control pressure ports in a fluidic manner, wherein the control pressure varying device is adapted to bring about the flow of the fluid at least majoritarily into a respective one of the outlets. Each of the outlets is connected to one individual opening of the plurality of openings.

Engine assembly for aircraft comprising an aerodynamic coupling fairing mounted on two separate elements

Abstract: The invention relates to an engine unit for aircraft, comprising an engine, an engine mounting device (4), a cowling enclosing the engine, provided with an air intake (32) and fan shrouds, the unit comprising a support cradle (40) for the fan shrouds fixed to the mounting device or to an assembly comprising a fan housing and the air intake, fixed to said housing. According to the invention, the engine unit has more than one aerodynamic coupling fairing (33) with first mounting means fixed to the cradle (40) and second mounting means fixed to other of the elements on the mounting device (4) and said unit.

Effects and defects of friction stir welds

Abstract: One of the major reasons often cited for using friction stir welding (FSW), particularly when it comes to the joining of light alloys, is the low incidence of flaws that can occur compared with those produced by conventional fusion (arc) welding processes. The FSW process does, however, have its own characteristic flaws. These flaws have been observed to occur in response to different FSW process variables including tool rotation and weld travel speeds, tool plunge depth (axial force), tool tilt angle, tool design, the size of gap between workpieces, thickness mismatch or plate thickness variation, tool offset to the join line, a lack of tool pin length in relation to workpiece thickness, as well as naturally occurring surface oxides remaining entrapped within the stir zone. This chapter discusses the origins of effects and defects, i.e. welding flaws, that can occur when FSW, their implications with regard to residual mechanical strength of the joint, and makes recommendations as how to identify why these occur and how to avoid their occurrence.
