The invention relates to an aircraft structure, the aircraft structure comprising a first component (12) and a second component (14). A fastening device (10) fastens the first component (12) to the second component (12), wherein the fastening device (10) comprises a clamping member (16), and a fastening member (20). The fastening member (20) has a longitudinal axis, and the clamping member (16) is associated with the first component (12) such that the clamping member (16) is movable in a first direction and is fixed in position in a second direction, the first direction being parallel to the longitudinal axis of the fastener (20), wherein the fastener (20) extends through the second component (14) into engagement with the clamping member (16) and holds the clamping member (16) against the second component (14). The fastening device (10) may hold the first component (12) and second component (14) in a fixed position relative to one another, in at least one direction, without applying a clamping force between the first component (12) and second component (14).

[Problem to be solved] Using the generally used coating method of an active material paste to a metal foil on a 3DF made the electrode properties instable due to residual air inside of the 3DF, and had the risk of causing micro short circuit of the battery due to metal fine powder and the like adhered to the 3DF and the 3DF exposed to the electrode surface. [Means for solving the problem] To solve the above-mentioned, the coating of the active material paste to the 3DF was made into a two-step coating process as shown below. Step one removes the air and fills the paste at the same time by applying the paste flow from one side of the 3DF (the first step coating process). Step two coats a new paste onto the surface of the electrode obtained by step one (the second step coating process). This electrode obtained by the two-step coating process hardly has remaining air amount, can uniformly confine metallic power dust or the 3DF itself inside the electrode (the first step coating process), and in addition to this, has the capability of Li ions freely moving between the electrode surface and the depth portion of the electrode through the opening portion formed on the tip portion of the innumerable protrusions of the 3DF, the micro short circuit of the battery due to Li dendrite was prevented even in repeated charge and discharge.

The invention provides an aircraft wing, comprising a fixed wing (14) and a wing tip device (12) at the tip. The wing tip device (12) is configurable between: (i) a locked flight configuration for use during flight and (ii) a ground configuration for use during ground-based operations. The wing further comprises a locking mechanism for locking the folding wing tip device (12) in the locked flight configuration. A rotatable locking member (22, 22') is associated with one of the folding wing tip device (12) and the fixed wing (14), and a locking pin (32) associated with the other. The rotatable locking member (22, 22') comprises a guide surface to guide the locking pin to a locked configuration, in which the guide surface is shaped such that the locking pin (32) is urged toward the rotation axis of the rotatable locking member (22, 22') by a camming action of the guide surface on the locking pin (32), thereby preloading the locking mechanism.
