CFM LEAP-1C-powered C919 makes its first flight

Release time: 2017-05-15 Hits: 3796

On May 5, the first C919 of COMAC successfully completed its first flight in 79 minutes, marking the official launch of a certification flight test project for the 150-seat passenger aircraft. In the era of global procurement of mature commercial passenger aircraft, many foreign companies have become global suppliers or partners of the C919, helping domestic large passenger aircraft to soar.

CFM LEAP-1C-powered C919 makes its first flight

CFM International provided the L919-1C integrated propulsion system as power for the C919. The LEAP-1C integrated propulsion system obtained airworthiness certificates issued by the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA) in December 2016. Since then, COMAC has conducted a series of ground tests, including low-speed and high-speed taxi tests before the first flight. COMAC selected LEAP-1C as the sole western power unit for the C919 passenger aircraft. The LEAP engine project was officially launched in December 2009. The engine uses a unique fully integrated propulsion system (IPS), including the engine, nacelle and reverse thrust. The integrated propulsion system and the hanger developed by COMAC are connected in design, which improves the aerodynamic design, reduces weight, and is easy to maintain.

GE Aviation Provides System Products for First Flight of C919

GE Aviation is an important supplier of C919 aircraft. Through its joint venture company Anggie Avionics, the C919 provides the following products: TrueCourse Flight Management System, Airborne Maintenance System, Enhanced Airborne Flight Recorder, Backup Display and Remote Control Interface Components. Angji Avionics provides integrated modular avionics system for C919. This system is the central information system of the C919 and the backbone of the aircraft network and electronic equipment. It supports the avionics, maintenance, and application system operations of the aircraft.

CTO's successful first flight

United Technologies Aviation Systems has a wide range of system-level integration solutions that allow aircraft manufacturers to build aircraft based on customer-specific requirements. On the successful first flight of the C919 aircraft, the advanced technology of United Technologies Aviation System can be seen everywhere. Key systems include power systems, emergency power systems, cockpit and throttle control systems, internal and external lighting systems, emergency actuation systems for cabin doors, fire protection systems, icing detection and anti-icing systems, and more.

Dassault Systèmes helps C919 make first flight with advanced software products

As one of COMAC's major software solution providers, Dassault Systèmes has been providing leading-edge software products and solutions for many years, providing strong support for the development of large aircraft projects. C919 uses CATIA software as the only design tool, combined with ENOVIA VPM collaborative development platform, to achieve a full 3D paperless design; use DELMIA to perform assembly simulation design to verify the assembly process of key components; use professional simulation software such as SIMULIA Abaqus Simulate and check the performance of complex structures and materials to ensure that they are met; use tools such as Composer to make deliverables such as maintenance manuals and training simulations. By researching and expanding with COMAC, Dassault Systèmes' 3D experience platform and concept can better serve COMAC's model development progress.

Honeywell's innovative technology helps C919 make its first flight

As one of COMAC's important international suppliers, Honeywell provided the C919 with four sets of advanced technical solutions and comprehensive supporting services, including auxiliary power systems, wheels and brakes, flight control work packages and navigation work packages. With these advanced technology solutions, Honeywell is working with COMAC to bring more efficient, safe and comfortable flight experience to C919 customers, pilots and passengers. In order to better support COMAC, Honeywell currently has more than 500 local engineers in China, most of which have provided support for the C919 project. In addition, hundreds of employees at Honeywell's 20 plants in Asia, North America and Europe also participated in the C919 project. Honeywell's two joint ventures in China-Honeywell Boyun Aviation Systems (Hunan) Co., Ltd. and Hongxiang Flight Control Technology (Xi'an) Co., Ltd., provide carbon brakes and fly-by-wire for the C919 Control solution.

Rockwell Collins helps C919 make first flight

The successful first flight of the C919 uses Rockwell Collins' communications and navigation solutions and an integrated cockpit monitoring system (ISS). The ISS developed by AVIC Leihua Collins (Wuxi) Avionics Co., Ltd. (ALRAC), a joint venture, combines weather monitoring, traffic alert and collision avoidance, mode monitoring and terrain early warning functions into an integrated system. The joint venture CLP Collins Avionics Co., Ltd. (RCCAC) developed communications and navigation avionics solutions. Rockwell Collins and Aviation Industry Blue Sky jointly developed the C919 engineering simulator to support the design and development of flight control systems, cockpit interiors and ergonomics, avionics and other necessary systems.
