ABSTRACT:
A method of converting an existing helicopter airframe, such as a UH-1H/V or a UH-1D, to a special purpose use such as, for example, a gunship or a firefighter, and a helicopter constructed thereby. The process takes a conventional, multi-passenger, helicopter from a primary design use to a second, un-anticipated use after the primary function has ceased. The invention converts the helicopter from a dual-piloted, multi-passenger aircraft to a helicopter gunship flown by a single operator/pilot. Modifying the aircraft involves stripping the entire shell from the basic boxlike airframe, removing all of the equipment and accessories, and re-assembling the aircraft with a slimmer profile, reduced weight, and improved performance.
