CSeries Program

The CSeries is a new generation of single aisle jet family,

designed to meet the demand of new models in the range of 110

to 160 passengers

It is forecasted a demand of 12,400

new small-medium aircrafts in 20

years period, being more than 50%

those corresponding to the range of

the 100 to 149 seats

CSeries family is composed by 2

models -CS100 and CS300- covering

the range of 108 to 125 passengers

and 130 to 160 pax, respectively

CSeries Program

This program implies a outstanding step in Bombardier

history. Not only due to the introduction of latest materials

and technologies (e.g. Fly by wire controls) , but also

represents the biggest aircraft ever developed by the this

company.

In this sense, the Canadian manufacturer competes for the

first time with smaller models of the larger EOM´s -Boeing

and Airbus- , with two relevant advantages: being the only

aircraft specifically developed for the 100-150 pax range,

and an earlier Entry into Service compared with its

competitors.

CSeries family presents a series of

competitive advantages, including

amongst others:

Cash operating costs reduction .

Environmental footprint reduction .

Fuel burn reduction.

Competitive Advantages

Competitive Advantages

15% Cash Operating Cost Reduction per seat, compared with currently

operated models:

Fuel Burn Reduction, -in

addition to latest generation

engine introduction-, is derived

from structural weight

reduction, close to 5,500 kg.

20% Fuel Burn Reduction per seat,

compared with currently operated models:

Competitive Advantages

10 Composite Materials in Canadian Collaboration 20140513 Miñano

Such weight reduction has been

obtained by extensively using advanced

structural material like new aluminum

alloys as well as composite materials.

Aernnova in the CSeries Program

Such collaboration has been focused on two

workpackages of both CS100 and CS300

models:

Center Wing Box

Tailcone

Aernnova, due to its large experience in the design and manufacturing of

composite materials structures, was selected to collaborate in the

development and production of this new aircraft.

Aernnova covers in CSeries, all program life cycle aspects from preliminary

design to “in service” support, including components manufacturing and

assembly.

Furthermore, in this program, Aernnova has developed the composite

qualification campaigns for the carbon fiber materials used in the

workpackages under its responsibility.

The use of composites in the aerospace sector is a reality that is

consolidating and growing continuously.

Products developed and produced by Aernnova follow this global trend,

playing composite materials a key role in those components under our

responsibility.

• It is a critical component, because it is located at “heart”

of the airplane, connecting both semi-wings and central

fuselage.

• Itts main components, like skin panles and spars have

been developed in composite materiasl, implying a

significant challenge because only last generation

aircrafts incorporate such technology in these

components

• These parts have been designed in carbon fiber

reinforced plastic with ATL technology on their

manufacturing process.

• Production and inspection of Center Wing Box parts involves last generation

processes like Automatic Tape Layup and hot forming.

• Together with the product, an exhaustive campaign of qualification of the composite

material has been developed to characterize it at the level of laminate, both in terms

of test specimen, as of subcomponent.

• Such characterization, has been carried out obtaining design allowable at different

configurations and conditions as:

• Defects simulation

• Environmental conditions

• Impacts

• Presence of holes (e.g. OHC/FHC)

• Integration of CFRP components into the

CWB structure represents also- aLa

integración de estos componentes en fibra de

carbono el resto de la estructura ha supuesto

–también-, a major challenge in the

development of drilling and assembly

processes due to the intrinsic characteristics

of thickness and combination of different

materials (carbon, aluminium, titanium)

Tailcone

• External panels as well as auxiliary power unit access doors have been designed

in carbon fiber, skin panels in solid hand layup fiber and core

• Complexity of this package is derived from component geometry and fire

resistance and temperature requirements originated by APU presence in this

compartment.

• Also for this component, an extensive composite material qualification has been

carried out to determine design allowables.
