    摘要： Some embodiments provide apparatuses configured to deploy a landing gear of an aircraft, comprising: a landing gear coupler 312 configured to couple with the landing gear; a release link 314 configured to cooperate the landing gear coupler with a drive shaft 114 that is configured to drive the landing gear between a stowed position and a deployed position; an override driver 316 cooperated with the landing gear coupler; wherein the release link is configured to releasably maintain a relative position of landing gear coupler relative to the drive shaft, and the release link is configured to disengage a coupling between the drive shaft and the landing gear coupler such that the landing gear coupler is configured to move independent of the drive shaft; and wherein the override driver is configured to drive the landing gear coupler to the deployed position.

    摘要： Apparatus and methods are disclosed for controlling the flow of a fluid over the window (615) of an optical instrument housing (600) in a freestream flow field (700). For example, the flow upstream of the housing may be split by an arcuate surface (510) having a curvature to create a flow region (715) over the window that is conducive to successful operation of the instrument. The flow region may be maintained for various rotations of the housing about yaw, pitch, and roll axes. The disclosed features in some embodiments induce flow regions with reduced spatial and temporal density gradients of the flow over the window.
