Abstract

An aircraft fuselage with a rear opening door and a pair of tracks in the bottom of the fuselage for a roll-in-roll-out cable train consisting of a series of connected cable cars. The cable cars are constructed so that the floor of the aircraft is part of the cable cars with passenger seats above the floor and baggage compartments attached below the floor. The entire cable train can extend rearwardly of the fuselage and into a separate adjacent building without disconnecting the cable train from the cable drive unit in the aircraft floor.

Claims

1. In a passenger and cargo handling system for an aircraft, an aircraft fuselage having a rear end ramp door hinged to the bottom of the fuselage to swing downwardly to an open position and upwardly to a closed inclined position, a pair of tracks in the bottom of the fuselage longitudinally thereof, a roll-in-roll-out cable train of cars guidably engaging said tracks, said cars each including a portion which constitutes a floor section of the aircraft and passenger seats above the floor sections and baggage compartments beneath the floor sections, an elongated substantially rigid drive tongue on the forwardmost car of said train, and an endless cable drive means in the fuselage engageable with said drive tongue including a return pulley at the rearmost end of said ramp door and cable guide pulleys at the hinge line of said ramp door with the fuselage, whereby when said cable train is fully extended rearwardly and outside of the fuselage the entire train is disposed rearwardly of the ramp door and adapted to enter an enclosure rearwardly of the aircraft without disconnecting the cable train of cars from said cable drive means in the fuselage.

2. In a passenger and cargo handling system for an aircraft, an aircraft fuselage having a rear end ramp door hinged to the bottom of the fuselage to swing downwardly to an open position and upwardly to a closed inclined position, tracks on the bottom of the fuselage longitudinally thereof, a roll-in-roll-out cable train of cars guidably engaging said tracks, said cars each including a portion which constitutes a floor section of the aircraft and passenger seats above the floor sections and baggage compartments beneath the floor sections, and at least the rear endmost car of said cable train being tapered in a vertical plane rearwardly to fit snugly in the rear of the fuselage above said rear end ramp door when the latter is in said closed inclined position.

3. In a passenger and cargo handling system for an aircraft, an aircraft fuselage having a rear end ramp door hinged to the bottom of the fuselage to swing downwardly to an open position and upwardly to a closed inclined position, tracks in the bottom of the fuselage longitudinally thereof, a roll-in-roll-out cable train of cars guidably engaging said tracks, said cars each including a portion which constitutes a floor section of the aircraft and passenger seats above the floor sections and baggage compartments beneath the floor sections, whereby when said cable train is fully extended rearwardly and outside of the fuselage the baggage compartments of even numbered cars in said train may slide laterally outwardly on one side of the train and the baggage compartments beneath the odd numbered cars may slide laterally outwardly on the other side of said train, allowing passengers to walk between the extended baggage compartments to deposit or pick up baggage, an automatic fold-down first passenger step attached to one side of each baggage compartment for use in cooperation with a second step, said second step comprising a platform placed over an inside top portion of each baggage compartment and used in cooperation with a third step which automatically folds out from beneath each car floor section, and said third step straddling the space between each pair of laterally extended baggage compartments, and hand holds on the passenger seats of said cars to assist boarding and departing passengers in conjunction with said steps.
