Abstract
Abstract A carrier including one or more guide tracks, an endless positioning chain associated with each guide track for supporting a payload item, and one or more drive motors for moving the chains in unison with respect to the guide tracks to move a payload item toward an ejection station. A fairing may be mounted in association with the guide tracks. The guide tracks encircle the aircraft fuselage and are maintained under sufficient tension to apply a radial compressive force to the fuselage for securing them thereto. The guide tracks are laterally rigid but are flexible radially to conform to a range of fuselage contours when subjected to a tensile force. The guide tracks thus may be secured to different aircraft in order to temporarily transform the aircraft into a military payload carrier, with minimal modification. Following military employment, the aircraft may be refurbished for non-military usage by removal of the carrier. The carrier is particularly suited for reversibly converting an aircraft to a platform for carrying and launching one or more rockets or cruise missiles.

Claim 4
Dependent Claim
34 words
The carrier of claim 2, wherein said conveyor assembly includes means mounted by the vehicle and acting between the vehicle and said chain for moving said chain with respect to said guide track means.
Claim 5
Dependent Claim
36 words
The carrier of claim 2, wherein said conveyor assembly includes means mounted by said chain and acting between said chain and said guide track means for moving said chain with respect to said guide track means.
Claim 6
Dependent Claim
38 words
The carrier of claim 2, wherein said guide track means include a plurality of elongated guide track sections and means for securing said sections together in end-to-end relation under a tensile load sufficient to apply said compressive force.
