Abstract: A quick release fitting for securing seating or other equipment to a section of aircraft floor track channel comprises a lower jaw member, an upper jaw member and multiple T-shaped cam members nested between locating dowels extending from the lower surface of the lower jaw member. The locating dowels are disposed in a plurality of adjacent cutouts in the floor track channel to locate the lower jaw member, and with it the rest of the quick release fitting. As the cam members are rotated to engage the aircraft floor track channel, the camming action draws the upper and lower jaw members together to squeeze a flange attached to the piece of equipment between the beveled facing surfaces of the upper and lower jaw members. Use of multiple T-shaped cams engaging the floor track channel adjacent a plurality of adjacent cutouts allows for better distribution of load along the floor track channel and the use of beveled jaws to support the equipment allows for angular misalignment of adjacent floor track channels.

Abstract: An angular position determining system utilizing an electronically scanned, linear phased array antenna radar system. The teachings of the present invention are applicable to airborne, ground or sea based radar systems for determining either elevation of azimuth. In one disclosed embodiment mounted in an aircraft for determining elevation, the linear phased array antenna is formed by a conformal wing array of radiating and receiving elements, wherein the phase front of the antenna beam can be controlled to steer the antenna beam by individually controlling the gain and phase excitation of each radiating element. The array comprises a left portion of the array and a right portion of the array, and each of the left and right portions is formed by a first plurality of elements tilted downwardly in elevation and a second plurality of elements tilted upwardly in elevation.
