According to CCTV reports, the reporter learned from the Aviation Industry Group,5moon12Japan, my country’s new multi-purpose helicopterAC352Completed the last flight test subject approved by the Civil Aviation Administration of China, and landed steadily at Jiansanjiang Wetland Airport in Heilongjiang.This marksAC352The helicopter certification test flight has been fully completed, and the countdown for model certification has entered.
AC352The special certification test flight of the Helicopter Civil Aviation Administration includesATake-off and landing-like, airspeed indication system, level flight performance, climb performance, stability and low-speed handling characteristics, etc.87subjects, total flight37.25Hour.
During the flight test, the Administration will check the flight test data submitted by the applicant,AC352The performance of the helicopter, the handling qualities and the working of the equipment were systematically evaluated.
follow up,AC352The helicopter will conduct functional and reliability test flights.
AC352The helicopter is an advanced medium-sized multi-purpose helicopter. This model adopts a conventional aerodynamic layout, dual-engine, wide fuselage, retractable wheeled landing gear at the front three points, and the cockpit space can carry14to16Passengers can meet the diverse needs of users.
AC352helicopter at2016year12The first flight in Harbin was successful.2019year11The month officially entered the applicant terms verification test flight.
AC352The advent of the helicopter fills the Chinese civil helicopter7The ton-level pedigree is blank, which is of great significance to promoting the serial development of my country’s helicopters and expanding the scale of the civil helicopter industry.
It is reported that,AC352Helicopter isCS29/CCAR-29Developed under the requirements of the Ministry of Airworthiness Regulations7Tonnage civil helicopter, using4Axis digital automatic flight control system(AFCS)highly integrated avionics,5The spherical flexible main propeller hub of the rotor and the anti-crash fuselage and other mature advanced technologies have the ability to fly day and night under visual and instrument flight rules.
maximum takeoff weight7500kg, maximum economical cruising speed280km/h, the maximum range is greater than1000kilometer.
AC352At the beginning of the helicopter’s development, the comprehensive support project was fully implemented to optimize the preventive maintenance program.The fuel consumption rate per kilometer is significantly lower than that of similar engines, effectively improving theAC352The range capability and endurance of the helicopter.
The high-strength aluminum alloy material is selected as the main structure material of the fuselage, which not only meets the strength requirements, but also reduces the production cost of the aircraft.
also,AC352The helicopter’s rotor system and airframe have a lifespan of up to20000hours, driveline and engine overhaul intervals up to5000hours, greatly reducing the user’s cost of use.
