According to the Aviation Industry Group,On January 24, the "Auspicious Bird" AC332 and AC352 helicopters successfully "reunited" at the Jiansanjiang Wetland Airport in Jiamusi, Heilongjiang., carry out test flight work separately according to the project plan. in,The AC352 helicopter has carried out a low-temperature load test flight and is expected to fly for 20 flight hours in a low temperature environment of -25°C to -40°C., to obtain the flight measured load and stress data of important components of the entire aircraft in a low-temperature environment.
The data obtained from this test flight will be used to re-evaluate the service life of the life-determined parts of the entire aircraft, solve the problem of relatively conservative initial service life, reduce use and maintenance costs, improve economy, and enhance market competitiveness.
As of now,The AC332 helicopter has basically completed the adjustment and flight test work, and has flown about 200 sorties in total., including the expansion of helicopter speed, height and weight center of gravity, as well as platform capability test flights such as helicopter balance characteristics, static stability, dynamic stability, and near-ground maneuverability.
While carrying out the airworthiness verification test flight, it also completed a high-cold test flight based on meteorological conditions.
AC352 (Z15) is a typeMedium multi-purpose helicopter, complies with the latest international airworthiness standards, applies a large number of mature and advanced technologies, and has outstanding performance advantages.On July 26, 2022, it successfully obtained the type certificate issued by the Civil Aviation Administration of China.
The AC332 is a 4-ton advanced twin-engine multi-purpose helicopter newly developed by the aviation industry. It will complete its first flight in full condition in Tianjin in 2023. It has signed 24 purchase agreements and intention agreements with the first users. It is expected to obtain the type certificate in 2025 and complete the first batch of deliveries.
AC332 meets the latest airworthiness requirements of CCAR-29. It adopts a single rotor, high-mounted ducted tail rotor, skid landing gear and clamshell rear hatch layout, and can carry 10 passengers.
In addition, the AC313A helicopter has completed the engine low-temperature starting test, engine in-flight restart test, environmental control system test and helicopter hovering performance, partial level flight performance, airspeed and rotor speed test flight test work in Mohe. The effective test flight time is about 20 hours.
The test flight results showed thatThe helicopter starting system has a 100% starting success rate at around -40°C.
The temperature of the environmental control system works normally throughout the entire process.Cockpit temperature above 15°C, greatly improving the user experience in alpine regions.
The helicopter has excellent flight performance and good flight quality in low-temperature environments.
The control load in the rotation state is moderate,The maximum takeoff weight is 13.8 tons, the ultimate rear center of gravity, and the maximum flight speed (indicated airspeed) is 340 kilometers/hour., which can better meet users’ performance requirements for large civil helicopters and achieve the purpose of high-cold test flights.
