Abstract
Abstract A stowable and inflatable vehicle, adapted for use as a decoy space vehicle and as a replica of a relatively hot parent space vehicle. In addition to other components, the inventive decoy and replica vehicle includes: a telescoping central tubular member that provides a rigid support and means for telescoping which aids in stowing the replica inventive vehicle; an inflatable structure which forms an external shape; and, a heater blanket in the outer layers of the structure to simulate the surface temperature of the parent vehicle. As a matter of preference, and in this adaptation, the inventive replica space vehicle is of a conical external configuration. The capability of this inventive vehicle to be inflated to the desired external shape, rather than to assume the external shape by use of solely mechanical expanding means, provides superior structural integrity, and also permits a significant reduction in external dimensions and easy storage, even where stiff materials (which are difficult to fold and to unfold) must be, or preferably are, used.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
194 words
A stowable and inflatable decoy space vehicle, having a fore end, an aft end, and a longitudinal axis, adapted for use as a replica of a relatively hot parent space vehicle, comprising: a. an outer covering of woven carbon cloth; b. a rigid nose tip disposed at the fore end of the decoy space vehicle and external of, and connected to, said outer covering; c. an inflatable liner internal of said outer covering; d. a heater blanket interposed between said outer covering and said inflatable liner; e. an extendable and a collapsable tube centrally located within the decoy space vehicle, in registration with said longitudinal axis of the decoy space vehicle, and extending from said fore end of the decoy space vehicle to said aft end of the decoy space vehicle, with said tube having a first end and a second end, wherein said first end interfaces with said rigid nose tip; f. means, internal of said outer covering, for inflating said inflatable liner; g. means, internal of said outer covering, for heating said heater blanket; h. and, means, internal of said outer covering, for extending and for collapsing said extendable and collapsable tube.
