Abstract: An improved multipurpose projectile obturator of composite, frangible conuction where the obturator preferably forms part of a projectile that is launched from an upstanding tube. The tube interior is provided with an alternating series of helically arranged groove and land means. A projectile at its propellant end is provided with an annular shoulder that faces in a direction toward the propellant end. An obturator is generally made up of an elastomeric band of a suitable grade of rubber. The band in being placed about the projectile surface and against the shoulder is positively retained as the projectile is inserted in the tube and launched therefrom. The outer periphery of the band has an annular groove for receiving a ring-like element. This element is preferably of three-ply construction and is also preferably made up of two half sections that are suitably bonded to the groove about the band periphery.

Abstract: Beam pointing errors and sidelobes resulting from temperature variations on he aperture and power divider of a series phased array antenna operating at a plurality of selected operating channel frequencies and having uniformly spaced elements are compensated for by placing a temperature sensor on both the aperture and power divider and converting the respective temperature outputs to digital signals which are fed to a digital beam steering unit. A pair of programmed memories are included in the beam steering unit which respond to an address or pointer corresponding to the digitized temperature values and the selected operating frequency to read out stored digitized beam steering phase gradients and feed phase corrections which are combined and sequentially applied at regular intervals to symmetrically located phase shifter pairs. A uniformly compensated beam is thereafter radiated at a predetermined phase angle.

Abstract: An air bearing for use with flight simulators or spin stabilized projecti having a primary axis of rotation. The device includes a fixedly mounted frame.
