Radome-antenna installation with rotating equipment rack
First Claim
1. In an aircraft having a fuselage, a pylon projecting from the upper end of said fuselage, and being fixed attached thereto;
- a radar surveillance system including a generally disc-shaped radome rotatably mounted above said pylon and having the maximum diameter thereof oriented in a plane substantially in parallel with the longitudinal axis of said fuselage;
antenna means fixedly secured within said radome;
a shaft extending vertically through said fuselage and traversing said pylon, said radome being fastened tot he upper end of said shaft;
means for imparting rotation to said shaft about the longitudinal axis of the shaft and concurrently to said radome and antenna means;
rack means mounted on said shaft interiorly of said fuselage, said rack means being rotatably with said shaft;
electronic surveillance system components operatively connected with said antenna means and including high-power RF and analog-to-digital conversion components being fixedly supported on said rack means for rotation therewith;
electric power generating means being mounted on said shaft proximate the lower end thereof for supplying electrical power to said system components and said antenna means; and
a generally disc-shaped shelf being mounted on said shaft proximate the lower end thereof and being rotatable with said shaft, said electric power generating means being fastened to the lower surface of said shelf.

Abstract
High-powered antenna installations employable in rotatable electrical systems for the transmission and reception of electromagnetic energy and, more particularly, an integral radome-antenna structure which is mounted for rotation on the exterior of an aircraft. The rotatable radome-antenna structure which is adapted to be mounted on aircraft, or possible on other suitable support installations, will prevent excessive electrical power losses encountered in present day structures, particularly inasmuch as the essential components, such as the antenna signal receiving and transmitting devices, power generating structure and air turbines, including cooling conduits for circulating coolant to and from the various components are mounted on the rotatable structure of the system, such as an equipment rack and shelf structure, so as to be rotated in conjunction with the radome-antenna structure.
