Abstract
Abstract A collapsible radome and antenna system in the form of a selfcontained pod which is attached to an aircraft by quick disconnect means. In collapsed position the radome is a shallow cylindrical structure and the reflector of the antenna is folded. The radome has telescopic sections which are extended to an open position, the reflector unfolding when the structure is extended and being mounted on a scanning mechanism to move within the radome. In one form the radome has a fail safe capability to collapse in an emergency.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
A collapsible radome and antenna system, comprising, a shallow, substantially cylindrical housing having means for attachement to an aircraft, a plurality of telescopically interconnected concentric ring elements of dielectric material nesting in said housing in a collapsed position, actuating the means for moving said ring sections between the collapsed position and an extended position forming a radome, and an antenna mounted in said housing, said antenna having a foldable portion which is contained in said housing in the collapsed position and extends into the radome in operative position, and the innermost of said concentric ring elements has a closed bottom cover of dielectric material.
Claim 2
Dependent Claim
104 words
A collapsible radome and antenna system, comprising, a shallow, substantially cylindrical housing having means for attachement to an aircraft, a plurality of telescopically interconnected concentric ring elements of dielectric material nesting in said housing in a collapsed position, actuating the means for moving said ring sections between the collapsed position and an extended position forming a radome, and an antenna mounted in said housing, said antenna having a foldable portion which is contained in said housing in the collapsed position and extends into the radome in operative position, and the innermost of said concentric ring elements has a closed bottom cover of dielectric material.
Claim 3
Dependent Claim
32 words
A collapsible radome and antenna system according to claim 1, wherein: said actuating means includes linear actuators mounted on said hOusing and having linearly movable portions connected to said innermost ring element.
Claim 4
Dependent Claim
24 words
A collapsible radome and antenna system according to claim 2, wherein: said linear actuators are mounted externally on said housing and circumferentially spaced thereon.
Claim 5
Dependent Claim
24 words
A collapsible radome and antenna system according to claim 1, wherein: said ring elements include substantially rigid ring elements interconnected by flexible ring elements.
Claim 6
Dependent Claim
27 words
A collapsible radome and antenna system according to claim 4, wherein: said housing has a closed top cover forming a substantially sealed enclosure with said ring elements.
Claim 7
Dependent Claim
30 words
A collapsible radome and antenna system according to claim 5, wherein: said actuating means includes an air blower communicating with the interior of said enclosure for extending the telescopic structure.
Claim 8
Dependent Claim
35 words
A collapsible radome and antenna system according to claim 6, wherein: said actuating means further includes cables connected to said innermost ring section; and a motor coupled to said cables for collapsing the telescopic structure.
