C 46 Aircraft - The Curtiss C-46 Commando was originally designed as a twin-engine high-altitude aircraft for civilian use, but its primary use was as a military transport during World War II, by the United States Army Air Forces. and it was also made by the United States. United States Navy and Marine Corps, and the latter two designated R5C. The order was also called "La Ballena" ("The Whale") or "La calamidad Curtiss" ("The Curtiss Calamity") by those who flew it.
Although not as twin-engined as the C-47 Skytrain, it was superior to the model due to its greater power, range and payload, features particularly valued in the Asian theater of war. Brings Douglas forward.
C 46 Aircraft
The CW-20 prototype, a 36-seat commercial airliner built by Curtiss-Wright, made its first flight on March 26, 1940. Due to its large body capacity, it is particularly suitable for cargo/transport and evacuation missions. The damage piqued the interest of the US Army, which ordered a militarized version of the C-46, powered by a 2,000 hp Pratt & Whitney R-2800-43 engine, called the Commando. In July 1942, the first CW-20B entered service, becoming the largest and most powerful aircraft in USAAF service and so valuable in the Pacific theater that by the end of production, more than 3,000 had been built.

In general, the C-46 closely resembled the CW-20 prototype, except that it had a different engine and a smaller number of windows. The second design, the C-46A, was provided with a loading door on the port side of the rear fuselage section, a reinforced holding floor, and folding seats for 40 men; The C-46's R-2800-43 engine was replaced by the Pratt & Whitney R-2800-51 of equal power but which provided better performance at higher altitudes.
After the loss of the Burma Road, C-46As, carrying vital supplies from India and China over the Himalayas, played a very important role in transporting military materials to Chinese territory and were crucial to the company's success. Performance of the Douglas C-47 at said altitudes.
In the Pacific, the command played a key role in the operations that ended in the defeat of the Japanese. One hundred and seventy US Army R5C-1s (as USAAF C-46A) made a significant contribution to them. Other versions produced for the USAAF included the C-46D model (CW-20B-2), which was used as a crew transport with an additional port door (1,610 built); service version of the C-46E (CW-20B-3), which has the same door arrangement as the C-46A and the sliding glass of the XC-46B (17 built); The C-46F (CW-20B-4), a cargo plane with doors on both sides and square wings, and a single example of the C-46G (CW-20B-5), which combines curved glass and square wings. The commando served with the USAAF/USAF and the USMC after the end of World War II. The USAF used one example of the C-46 in the Korean War and in the early stages of the Vietnam War. A very small number continued in service for several years.
A few spare C-46s were briefly used in their original aircraft role, but a large number of surplus C-47s soon returned the C-46 to transport duties. In the United States Air Force, he continued to serve in secondary roles until he finally retired in 1968. However, she continued her operational life into the 21st century as a rough cargo ship that operated on poorly prepared roads.

The original commercial aircraft prototype, designed with a dihedral tail and trailing tail, is powered by two 1,268 kW (1,700 hp) Wright R-2600 Twin Cyclone radial engines.
Modification of the original CW-20T prototype, redesigned tail with larger flare and single fin, and a non-dihedral tail and other improvements, including a change to the Pratt & Whitney R-2800-5 radial engine. It was used as a prototype aircraft for the C-46 military transport, as was the XC-46. Later sold to BOAC.
