The cockpit and all fuselage sections for the Bombardier CSeries first flight test vehicle (FTV1)  have arrived at Bombardier’s final assembly line for the CSeries at Mirabel, Québec, and assembly of FTV1 has begun.

Additionally, the first Bombardier CSeries wings are now being mated to the test airframe that will be used during the Complete Airframe Static Test (CAST). Located at the company’s Experimental Test Facility in St-Laurent, Québec, the CAST is designed to demonstrate the static strength of the airframe and show compliance with certification requirements.


According to Bombardier Aerospace, testing of the avionics, electrical, flight control, fly-by-wire, hydraulic, landing gear and wiring systems for the CSeries, as well as virtual flights, are also progressing steadily at Mirabel on “Aircraft 0” − the on-the-ground Integrated Systems Test and Certification Rig (ISTCR) for the CSeries.

By October 15, 2012, the cockpit and all fuselage sections for the first Bombardier CSeries flight-test aircraft, known as FTV1, had arrived at the CSeries final assembly line at Mirabel, Québec, and assembly of FTV1 had begun

 

Bombardier Aerospace’s Mirabel facility will be the production site for the CSeries family of commercial jets and the assembly process will include a fully automated moving line using the latest lean manufacturing principles.

“The CAST, FTV1 and ‘Aircraft 0’ are all key elements in the testing and development of the CSeries aircraft and we are delighted with the progress on each of these three test platforms, says Rob Dewar, vice president and general manager, CSeries, Bombardier Commercial Aircraft.

“Aircraft 0 is permitting us to validate the CSeries aircraft’s systems in an efficient, on-the-ground setting that allows us to work seven days a week and 20 hours a day,” Dewar continues. “Our findings will allow us to optimize the time spent in the flight test program. The integrated systems tests on ‘Aircraft 0’ are designed to mitigate risks and provide the necessary reliability before first flight. To date, tests have shown no unexpected results and all is going as planned.”

Adds Dewar: “Subsequent to the extensive research and test program at Bombardier Aerospace Belfast, which was used to optimize the final production design for weight and performance for the wings, the CAST will be used to confirm [the wings’] static strength along with that of the other components of the airframe.”

In October 2012, Bombardier began mating the first Bombardier CSeries wings to the test airframe to be used during the Complete Airframe Static Test (CAST) for the CSeries

 

The wings for the CSeries were built at Bombardier’s new 600,000-square-foot (55,742-square-meter) manufacturing and assembly facility in Belfast, Northern Ireland. The facility is responsible for the design, manufacture and integration of the advanced composite wings for the Bombardier CS100 and CS300 jets, including all flight control surfaces and high-lift systems.

According to Bombardier Aerospace, the use of resin impregnation has enabled the manufacturing of larger and more complex composite structures in the aviation industry.

Bombardier Aerospace Belfast has been a leader in that manufacturing revolution, developing and patenting its unique Resin Transfer Infusion (RTI) process, which is now being used in manufacturing the primary structural components of the wings for the CSeries aircraft.

The use of composites in such a large structure as the CSeries wing not only provides weight savings, but also allows for fewer inspections and lower maintenance costs, thanks to the corrosion-resistance properties and fatigue strength of the composite material.

The Bombardier CS100 is the first member of the new CSeries airliner family to enter service. The CS100’s planned in-service date is late 2013

 

According to Bombardier Aerospace, the composite manufacturing process being employed at its Belfast facility also permits a high degree of accuracy and aero smoothness to minimize drag and therefore reduce the CSeries aircraft’s fuel burn.

The advanced technology, carbon-fibre wings for both the Bombardier CS100 and Bombardier CS300 versions have an approximate area of 1,209 square feet (112.3-sq.-m) and a span of 115 feet 1 inch (35.1 meters). While some of the internal parts for the wings of the two models will be different, they have the same aerodynamic profile.

During the CAST, the wing and other components of the airframe will be subjected to a series of load cases – representing flight maneuvers, landing, take-off and other in-flight and on-ground conditions − to test the strength of the airframe.

For selected load cases, internal cabin pressure will also be applied when simulating in-flight conditions. Data collected will be monitored by Bombardier’s stress engineers, as well as by the partners and suppliers that are involved in the development of structural components for the CSeries jets.

The Bombardier CS300 is the larger of the two versions of the CSeries family and enters service later than the CS100, its smaller sibling

 

Bombardier Belfast manufactured the center fuselage for FTV1, while the forward and aft fuselage sections, as well as the cockpit, were supplied by Bombardier’s St-Laurent facility. The rear barrel was supplied by Shenyang Aircraft Corporation (SAC), a subsidiary of the state-owned Chinese aviation industrial entity, China Aviation Industry Corporation (AVIC).

As in the production of the wings for the CSeries aircraft, Bombardier has capitalized on its expertise in composite-materials technology in the development of the airliner’s aft fuselage. For the carbon-fiber aft fuselage, including the pressure dome, the company is using Automated Fiber Placement (AFP) techniques.

Bombardier’s adaptation of AFP technology, which is also making use of robotic technology, has benefited from the largest collaborative aircraft structures demonstration project initiated by Canada’s National Research Council to advance AFP use in the aerospace industry.

The company is employing a new moving line in manufacturing the cockpit for the CSeries at its St-Laurent facility. The line has been designed using lean manufacturing principles in order to ensure safety for the company’s employees, to enhance product quality and to provide flawless execution for on-time delivery.
