Abstract: An exhaust nozzle for an aircraft propulsion system includes a nozzle wall and a nozzle ring. The nozzle wall extends axially along an axis from an upstream end of the nozzle wall to a downstream end of the nozzle wall. The nozzle wall includes an inner skin, an outer skin and a cellular core between the inner skin and the outer skin. The inner skin forms an outer peripheral boundary of a flowpath axially along the nozzle wall. The nozzle ring forms a downstream trailing edge of the exhaust nozzle. The nozzle ring projects axially out from the downstream end of the nozzle wall to the downstream trailing edge of the exhaust nozzle to form another outer peripheral boundary of the flowpath axially along the nozzle ring. The nozzle ring is axially abutted against the cellular core. The nozzle ring is bonded to the inner skin and the outer skin.

Abstract: The invention relates to a dual polarized wideband array antenna using orthogonal feeding technique to have a low profile and a cosecant squared beam. The array antenna includes three main parts: the element antennas, the orthogonal feeding structure and the feeding network. The spatially orthogonal feeding structure is a transition between the microstrip lines on element antennas and the striplines on the feeding network. The top layer of the feeding network operates as a ground plane for the array antenna. Due to the disparities between the stripline lengths, the phase parameters of element antennas are optimized to create a cosecant squared radiation pattern.
