An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a distal end of the wiper arm, and a drive shaft coupled to a proximal end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The drive shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across the windshield. The wiper arm includes both composite and metal components to reduce the weight of the windshield wiper system while also providing lightning strike protection.

An attachment for a wiper arm of a windscreen wiper of a vehicle, having a rod arm, comprises a fluid channel for conducting a fluid and a first dimensionally stable element, wherein a first fluid channel section is formed in the first dimensionally stable element. The attachment also comprises a second dimensionally stable element, wherein a second fluid channel section is formed in the second dimensionally stable element. A wiper arm including the attachment is also disclosed.

A front structure of a vehicle includes an electrical component provided below a front windshield, and a gutter member, provided immediately behind the electrical component and below the front windshield, that receives the water dripping from the front windshield, in which the gutter member has a flow path portion through which the water drops dripping onto the gutter member flows in the vehicle width direction, and the flow path portion includes an uppermost portion that is set the highest at a position at which the electrical component is provided in the vehicle width direction, and inclined portions, disposed adjacent to the uppermost portion in the vehicle width direction, that extend downward toward the inner side in the vehicle width direction and the outer side in the vehicle width direction.

A windshield wiper arm is provided on an outside of an aircraft and positioned to directly engage an air flow while the aircraft is traveling. The wiper arm includes an arm portion coupled to the aircraft and having an arm exterior surface, the arm portion extending along an arm axis and defining an arm length. A bead extends outwardly from the arm exterior surface and defines a bead exterior surface, the bead being sized sufficiently to engage a boundary layer of the air flow. A wiper blade is coupled to the arm portion. The bead prevents separation of the boundary layer from the arm exterior surface, thereby to attenuate shedding of vortices and associated vibrations and noise.

Wiper arm (1) with pantograph dynamic action, comprising a main rod (2a) and a secondary rod (2b), characterized in that of the said main rod (2a) and secondary rod (2b) each comprises a negative lift surface profile the cross section of which is delimited by an upper side (25a, 25b), a lower side (26a, 26b), and, in the direction of the air flow, an anterior edge (23a, 23b) referred to as the leading edge and a posterior edge (24a, 24b) referred to as the trailing edge opposite the leading edge (23a, 23b),
and in that, in the position as mounted on a vehicle, the arm (1) is positioned with respect to the vehicle surface that is to be wiped in such a way that the said lower sides (26a, 26b) of the cross sections of the rods (2a, 2b) face towards the surface that is to be wiped, so as to press the arm (1) more firmly against the surface that is to be wiped.
