PARIS AIR SHOW: Parker controls the C-Series

Parker Aerospace has won contracts for four systems in the recently launched Bombardier CSeries airliner, including the fly-by-wire flight control system.

Parker, a specialist in motion and control technologies, has also been contracted to supply the CSeries' fuel tank inerting system and its integrated fuel and hydraulic systems. It estimates that the contracts will generate around $5 billion in revenue over the life of the CSeries programme. The five-abreast, single-aisle 100- to 150-seater is planned for service entry in 2013-14.

Bombardier has also signed up Parker for 10 years to develop fly-by-wire systems for all planned or future aircraft from its stable on which it is specified. The Learjet 85 is not planned to have FBW controls. Parker says it will be developing "a complete, state-of-the-art, generic fly-by-wire system from stick to surface, that will then be customised and manufactured for separate aircraft programmes, starting with the CSeries aircraft".

The fuel tank inerting system, says Parker, uses air separation modules with patented fibres provided by its filtration and separation division. Air separation modules generate nitrogen-enriched air by removing the oxygen molecules from an air source and distributing the remaining nitrogen to all the aircraft's fuel tanks, reducing the flammability of fuel vapours in the tanks.

Parker's fluid management and control systems organisation will design the fuel system for the CSeries aircraft, and provide the control valves for fuel and emergency shut-off, isolation, and venting of air in and out of the aircraft fuel tanks.

The hydraulic system will be produced by the Parker Hydraulic Systems division, and it will provide the functions to power and control the aircraft's flight control surfaces, landing gear and steering system, thrust-reverser and variable-area nozzle system.

Major system hardware elements include engine-driven pumps, VFAC-motor-driven pumps, a power transfer unit, reservoirs, accumulators, and filtration. Additionally, Parker will provide ancillary equipment, including heat exchangers, various sensors, valves, and quick-disconnect couplings.
