Abstract: Embodiments of the present disclosure relate to a belly-mounted retraction mechanism for a payload in a fixed wing UAV. The retractable payload can be a two-axis camera system designed to fit inside the aircraft fuselage cross section. The disclosed retraction mechanism is a servo driven direct link mechanism configured to drive the payload between its retracted/stowed position & projected position by pivotally moving the payload about a horizontal axis. The retraction mechanism gets mechanically locked in retracted and projected positions and can only be moved when driven by the servo thus preventing any unintended movements due to inertia or gravitational forces. The retraction mechanism further comprises a spring to bias the payload against gravitational force for smooth descent of the payload and a slider flap to close the opening when the payload is moved to deployed position.

Abstract: The present disclosure relates to a control system for a retractable belly mounted payload in an Aerial vehicle for retraction, pan and tilt movements of the payload, comprising a first mechanism to rotate the payload about a vertically oriented first axis for pan movement of the payload, and a second mechanism to rotate the payload about a horizontally oriented second axis, wherein rotation of the payload about the second axis provides movement of the payload between a retracted position within belly of the Aerial Vehicle and a deployed position out of the belly of the Aerial Vehicle, as well as tilt movement of the payload in its deployed position. First mechanism is driven by a servo through a set of gears or pulley-belt mechanism, and second mechanism is driven by a directly connected servo connected to the payload. Both the servos rotate along with payload during pan movement.

Abstract translation: 本公开的实施例涉及用于固定翼UAV中的有效载荷的安装在腹部上的回缩机构。 可伸缩有效载荷可以是一个两轴相机系统，设计用于安装在飞机机身横截面内。 所公开的收缩机构是伺服驱动的直接连杆机构，其被配置为在有效载荷的缩回/收起位置和收起位置之间驱动有效载荷。 通过使有效载荷围绕水平轴线枢转地移动来预测位置。 缩回机构机械锁定在缩回位置和伸出位置，并且只有在伺服驱动时才能移动，从而防止由惯性或重力引起的任何意外移动。 收缩机构还包括弹簧，以抵抗有效负载的平稳下降的重力偏置有效载荷，以及当有效载荷移动到展开位置时关闭开口的滑动挡板。
