IT Home reported on October 16 that IT Home learned from the WeChat public account of Aviation Industry Corporation of China that on October 10, China's self-developed large amphibious aircraft AG600 launched a fatigue test of the whole aircraft.
According to the results of the field test, the fatigue test of the AG600 aircraft was running smoothly and the load application was accurate, which met the design expectations.
As a large amphibious aircraft designed in accordance with the requirements of the "Airworthiness Standard for Transport Aircraft" (CCAR25 part), AG600 aircraft needs to have both aerodynamic and hydrodynamic performance requirements, and there are many differences with conventional land-based aircraft in structural design, use mode and service environment.
AG600 aircraft fatigue test is the most special and most complex load of the current mission profile, is the structural strength of the professional after the static test of the whole aircraft another aircraft level structural test, is the most important test to verify the aircraft damage tolerance of the structure and fatigue assessment of the compliance with the relevant regulations and provisions, the test will verify the fatigue and damage tolerance analysis method of the aircraft structure, for the future aircraft life extension and modification of the aircraft to provide an important full-scale test basis.
AG600 is a large-scale special-purpose civil aircraft independently developed to meet the urgent needs of forest fire fighting and water rescue, and is a major aviation equipment urgently needed for the construction of national emergency rescue system. The AG600 is powered by four turboprop-6 turboprop engines, has a maximum take-off weight of 49 tons, a maximum range of more than 4,500 km, a wingspan of 38.8 m, a cruising speed of 480 km/h, and a rescue radius of 864 nautical miles (1,600 km). It can draw 12 tonnes of water in 20 seconds, can carry 50 people in distress, and is resistant to waves up to 2.0 meters.
