Design
High wing with two piston engines .
Options and Modifications
- XC-123 is a prototype for the series, a military transport aircraft converted from an XCG-20 glider with two 1900-horsepower piston engines and three-blade Curtiss Electric propellers.
- XC-123A is a military transport aircraft equipped with four J47-GE-11 turbojet engines (each with a thrust of 2720 kg). The only prototype was created. After testing, converted to C-123B.
- C-123V - serial modification of the aircraft. Equipped with two 2300 strong piston engines R-2800-99W with three-blade propellers Hamilton Standard. Capacity 61 paratroopers or 50 wounded. Were built - 1 glider for static tests, 5 aircraft company Chase and 302 Fairchild Aircraft .
- ΠΠ‘-123Π - a coast guard aircraft created on the basis of C-123Π. Equipped with radar APN-158.
- UC-123V - special aircraft. destination for spraying the Agent Orange defoliant (10 cars) in Vietnam .
- C-123C - modification with the possibility of suspension of two 1700 liter outboard fuel tanks.
- YC-123D - military transport prototype aircraft. It was equipped with two 2780-horsepower Pratt-Whitney R-2800-99RE piston engines with four-blade propellers Hamilton Standard. It had a system for blowing off the boundary layer from the flaps, two-wheeled struts of the main chassis, and there was the possibility of installing outboard fuel tanks.
- YC-123E - an experimental version of the aircraft S-123C. The aircraft modified in accordance with the Pantobase concept (based everywhere) had a sealed fuselage with a bottom in the form of a boat bottom, a conventional landing gear, a pair of retractable water-snow skis and a pair of underwing floats. XC-123E could be operated from almost any surface: earth, water, snow, ice and sand.
- YC-123H - was built to study the possibility of suspension on pylons under the wing of additional turbojet engines General Electric J85-GE-17 (each thrust 1293 kgf). This modification was supposed to accelerate the start and increase the initial rate of climb.
- C-123J - modification of model B aircraft (10 aircraft, 1957). Intended for use in the polar regions. Skis and additional turbojet engines Fairchild J44-R-3 were installed to control the boundary layer. Mounted on wingtips in gondolas.
- C-123K - modernization of 183 cars. Used in Vietnam from small airdromes with unpaved surfaces. They were distinguished by more powerful 2850 Pratt-Whitney R-2800N powerful piston engines, installation of additional General Electric turbojet engines J85-GE-17 , a chassis with pneumatics of increased diameter and low pressure, with automatic braking. To maintain stability, a well-developed fork is installed on the course. On some cars, the Hughes weather radar was in an elongated nose fairing.
- UC-123K is a special-purpose aircraft created on the basis of the S-123K. Used in Vietnam to use chemical weapons in Operation Ranch Hand . 34 cars were converted.
- VC-123K - VIP transport for William Westmoreland, Commander of the Military Assistance Force for Vietnam . Built in a single copy.
- AC / NC-123K - 2 C-132B vehicles were converted with the Black Spot program . Equipped with additional sensors for aerial reconnaissance at night, as well as argon lights and equipment for dropping cluster bombs .
- C-123T - A modernization option for the C-123B Thai Air Force, proposed in 1979 by the American company Mancro Aircraft Company. He envisaged the installation of new, more powerful turboprop engines Rolls-Royce Allison T56-A-7 and fuel tanks of increased capacity. The cost of upgrading one aircraft was estimated at 3.5 million US dollars [1] . In fact, in 1981, one instance went through modernization.
