Tthe 드 하빌랜드 캐나다 DHC-4 카리부 (미군에 의해 CV-2 및 이후 C-7 Caribou로 지정됨)은 캐나다에서 설계되고 생산된 특수 화물 항공기로 짧은 이륙 및 착륙(STOL) 능력을 갖추고 있습니다. Caribou는 1958 년에 처음 비행되었으며 주로 군사 작전에서 은퇴했지만 여전히 견고한 "부시"항공기로 소량으로 사용되고 있습니다.
Tthe 드 하빌랜드 캐나다 DHC-4 카리부(designatedCV-2and laterC-7in U.S. service) was designed to do the impossible: carry the payload of a medium transport while operating from the tiny, rugged airstrips normally reserved for light bush planes. Known for its incredibleShort Take-Off and Landing (STOL)capabilities, the Caribou became an indispensable asset during the Vietnam War, delivering supplies directly to remote Forward Operating Bases that no other fixed-wing aircraft could reach.

Engineering for the Jungle Strip
Double-Slotted Flaps:The Caribou used a sophisticated full-span double-slotted flap system. This allowed the wing to generate massive lift at very low speeds, enabling the aircraft to “climb like a homesick angel” immediately after a short takeoff roll.
Upswept Tail and Rear Ramp:To facilitate rapid loading of vehicles and palletized cargo, the rear fuselage was sharply upswept. This provided a high-clearance rear loading ramp that could be opened in flight for paradrops or used on the ground for drive-on access.
Reversible Pitch Propellers:To achieve its legendary landing distances, the Caribou utilized reversible pitch propellers. Upon touchdown, the pilot could “reverse” the thrust, allowing the aircraft to stop in a distance shorter than its own wingspan.
Long-Stroke Landing Gear:The “bird-like” landing gear was designed with massive shock-absorption capabilities to handle the high sink rates and “controlled crashes” associated with landing on uneven, unpaved terrain.
Operational Legacy: The “Gravel Truck” of Vietnam
Inter-Service Rivalry:The Caribou was so successful at tactical airlift that it sparked a famous dispute between the U.S. Army and Air Force over who should operate fixed-wing transports. Eventually, the Army’s CV-2s were transferred to the USAF as C-7s.
Low-Altitude Extraction (LAPES):The Caribou was a pioneer in theLow Altitude Parachute Extraction System, where cargo was pulled out the rear ramp via parachute while the aircraft flew just feet above the runway.
Durability:The aircraft was built to be simple and maintainable in the field. Its radial engines were reliable and could be serviced with minimal tools in harsh environments.
Global Service:Beyond the US and Canada, the Caribou served with distinction in Australia, India, and Spain. Many are still used today by private contractors for specialized heavy-lift bush operations.
