The deHavilland DHC4 Caribou

MULTI-ROLE TRANSPORT

 (US Army CV-2) (USAF C7A)

 

The Tested and Proven STOL Aircraft Unique in its Class

 

 

The DHC-4A Caribou is a twin engine utility passenger-cargo aircraft capable of carrying loads of up to four tons for the legacy aircraft and in excess of five tons for the new Turbo powered variant. Its exceptional short take off and landing characteristics enable it to operate from jungle airstrips, beach heads and other restricted airfields normally accessible only to light aircraft.

 

The Caribou structure is conventional, simple and rugged and is capable of absorbing maximum punishment with a minimum of field maintenance.

 

The full span double slotted flaps and large tail provide excellent control and maneuverability, particularly for low level, low speed operations in forward areas. A wide center of gravity range allows an unusual variety of cargo loading arrangements.

 

The Caribou cabin is convertible in minutes to any one of several configurations, including Fuel Tanker, Vehicle Transporter, or Freighter. As a civil transport, it accommodates 30 passengers and baggage. A collapsible rubber bladder tank can be quickly installed to facilitate the carriage of fuels like Diesel, Jet A1 or Avgas. The tank may also he plumbed to a dispersal system for oil pollution control.

 

Cargo tie down points are liberally provided, permitting full use of the entire floor area. The floor is designed for high density loading of 2OO lb/sq. ft. Structural provisions are incorporated for a monorail and cargo buffer boards can be provided on the sidewalls.

 

Forward facing "Utility" type or inward facing “troop” seats can be installed, which fold compactly against the wall when not in use.

 

The Caribou can be converted to an air ambulance to accommodate 22 standard litters and 4 seats for attendants or sit-up cases. Hospital equipment can be carried in combination with various arrangements for Seats and litters.

 

Large rear cargo loading doors facilitate the rapid handling of bulky cargo and contribute to short ground turn around times. Separate passenger loading doors are provided on both sides of the rear fuselage.

 

The rear loading door, approximately 38.2 sq. ft. (11.57 sq. m) in area is built in two parts. The upper portion retracts into the tail roof structure, permitting a 3-ton truck to back into the opening. The lower section acts as a ramp, which can be adjusted to match truck bed heights. Cargo can then be quickly rolled into the cabin on roller conveyors or a monorail can be installed.

 

With portable ramp extensions, wheeled vehicles can be driven up or down the adjustable sloping ramp under their own power. Heavy objects can he skidded in and out with the assistance of a winch.

 

The handling performance of the aircraft in flight is unaffected when flying with the cargo doors open. This makes it possible to carry very long items of cargo, such as pipes, by permitting them to project aft through the partially open doors.
