Abstract: An aerodynamic cover panel for a landing gear wheel well in an undercarriage of an aircraft includes at least one embodiment having a peripheral lip that defines a plane. Movements of the cover panel to open and close the wheel well are confined to pivotal rotation within the plane, and occur within an aerodynamic boundary layer of the undercarriage about a pivot axis in one rotational direction to open the wheel well, and in an opposite rotational direction to close the wheel well. The cover panel includes a flange, to which a rotary shaft is secured at one end for rotation about the pivot axis. The other end of the rotary shaft is secured to an actuator fixed within the undercarriage. In one embodiment, the cover panel rotates about an arc of least 75° between fully opened and fully closed positions of the wheel well.

Abstract: A window assembly for an aircraft is provided that includes a windshield, a side window, a post, and an airflow surface. The windshield is oriented toward a front of the aircraft. The side window is oriented toward a side of the aircraft. The post is interposed between the windshield and the side window. The airflow surface is disposed on the post and on an exterior of the aircraft. The airflow surface extends along a length from a leading edge proximate the windshield to a trailing edge proximate the side window, and extends along a height between a top and a bottom. The airflow surface has a first radius of curvature proximate the leading edge and a second radius of curvature proximate the trailing edge, wherein the first radius of curvature is less than the second radius of curvature.
