DESCRIPTION:

BRIEF SUMMARY
The technical field to which this invention relates is that of aircraft-carrying ships. This invention allows V/STOL aircraft operating in their most capable horizontal-launching mode to be deployed at sea more widely and economically than at present by allowing their deployment on cruisers, destroyers, assault ships and support ships that currently cannot deploy them, in greater numbers on aircraft carriers the size of the current smaller carriers, on small carriers smaller than any current carriers, and on more versatile carriers with unconventional hull types. This is possible because the invention is a vessel with a novel combination of aircraft-related features, a combination that is cheap, fits compactly on a single deck, requires minimum use of mechinery, requires development of no novel construction or flight operation techniques, and that permits easy adaptation into a form allowing the vessel to be fitted as one of the above vessel types.


TERMINOLOGY

The following terms hereinafter have the following meanings.
"vessel" is a waterborne or amphibious ship, vessel or craft.
"hull and propulsive system" is the hull or equivalent and the means of propulsion of a vessel.
"CTOL aircraft" are fixed-wing aircraft like the McDonnell Douglas F/A-18 which launch and land horizontally in the conventional manner on a long runway or on a medium-length runway if assisted by catapults and arresters.
"STOL aircraft" are fixed-wing aircraft that launch and land unassisted horizontally on a short runway.
"V/STOL aircraft" are fixed-wing aircraft like the British Aerospace Harrier that can launch and land unassisted both horizontally on a short runway and vertically.
"STOVL aircraft" are V/STOL aircraft when their manner of operation is to usually launch horizontally and to land vertically.
"V/STOL-as-VTOL aircraft" are V/STOL aircraft when their only manner of operation is to launch and land vertically.
"VTOL aircraft" are V/STOL-as-VTOL aircraft or aircraft such as helicopters which can only launch and land vertically.
"aircraft" are CTOL, STOL, STOVL or VTOL aircraft.
"take-off runway" is a runway on a vessel aligned approximately in the fore and aft direction and having unobstructed air space forward of its forward end so that CTOL, STOL and/or STOVL aircraft can launch from it.
"catapult" is the device usually called that embedded in a take-off runway and used on vessels to assist CTOL aircraft launching.
"ski jump" is the ramp usually called that located at the forward end of a take-off runway and inclined upward in the forward direction and used on vessels to assist STOVL aircraft launching.
"landing runway" is a runway on a vessel aligned approximately in the fore and aft direction and having unobstructed air space above and abaft it so that CTOL and/or STOL aircraft can land upon it; in this specification, even if a such a runway is also a take-off runway, a landing runway will still be described as existing.
"arresters" are the wires and nets usually called that located on a landing runway and used on vessels to assist CTOL aircraft landing.
"runway" is a take-off runway or a landing runway.
"pad" is a take-off or landing pad on a vessel, this being a level area of open deck and having unobstructed air space around it so that VTOL aircraft can launch and/or land upon it; in this specification, even if such a pad is no more than a section of a runway suitable for the launching and/or landing of VTOL aircraft, a pad will still be described as existing.
"draw-down device" is the device usually called that located on a pad and used on vessels to assist VTOL aircraft landing.
"parking area" is a level area of open deck on a vessel where aircraft can be temporarily parked prior to launching or when their removal from a hangar is required; in this specification, even if such an area is no more than a suitable part of a runway or pad, a parking area will still be described as existing.
"hangar" is the structure usually called that on a vessel, this allowing the accommodation of aircraft; in this specification, e
