Avicopter AC-313 is a multi-purpose civilian helicopter developed by the Chinese aircraft manufacturer AVIC Helicopter Company (“Avicopter”).
The Avicopter AC-313 helicopter also referred to as the Changhe Z-8F-100, began to be developed by aircraft manufacturers from the AVIC Helicopter Company in the 2000s. As a starting base, Chinese aircraft developers used a Harbin Z-8 model military helicopter, essentially optimizing its design and providing wide functionality for subsequent operation in the civilian aviation industry.
The appearance of the Avicopter AC-313 helicopter practically did not undergo any significant changes, however, the design became simpler, which reduced the cost of production, however, it did not at all affect the safety of the flights made. It should be noted that the use of ready-made design and construction of the helicopter also minimized the design costs, reducing development time, which led to a fairly favorable price
The first test tests of the Avicopter AC-313 helicopter were carried out by Chinese specialists in 2010, however, the aircraft of this model was officially introduced only in 2013, which was explained by the need to prepare the production.
Considering the official data of the AVIC Helicopter Company aircraft manufacturing company, over two years of production, from 2013 to 2015, 10 Avicopter AC-313 helicopters were built, which indicates a high demand in these aircraft in the field of civil aviation.
Onboard, the Avicopter AC-313 aircraft can transport up to 6 tons of payload, including oversized cargo. In some cases, the load can be attached to an external hitch, however, for such purposes, a helicopter is used quite rarely due to the low maneuverability of the aircraft. In addition to transporting goods, the Avicopter AC-313 helicopter is also used for transporting people, in particular, up to 27 passengers can be accommodated onboard an aircraft of this model, while 2-3 crew members are required to control the aircraft.
The power plant of the Avicopter AC-313 aircraft, also called Changhe Z-8F-100, includes three Pratt & Whitney Canada PT6B-67A gas turbine engines, each of which has a capacity of 1220 hp, which provides a helicopter with high load capacity, as well as a sufficiently high flight speed of up to 250 km \ h. (maximum flight speed). The Avicopter AC-313 helicopter can fly at distances of 1050 kilometers, however, this figure can vary depending on the load of the aircraft, which, nevertheless, is very acceptable.
