Bombardier remains on track to complete the joint definition design phase of its new CSeries aircraft by month's end, followed by the start of engine testing this summer.
Programme vice president Rob Dewar says that 47 work packages needed completion in the joint definition phase, and as each package reaches the completion milestone, it moves to detailed design phase. The last package makes its exit from joint definition this month.
Dewar says one of many items confirmed in the CSeries joint definition phase was maintenance reliability targets for the 110-130 -seat CS100 and CS300 aircraft powered by the Pratt & Whitney PW1000G geared turbofan.
The airframer also claims that as the CSeries exits joint definition phase the 110-seat CS100's cash operating costs advantage now appears to have a 16% cash operating cost advantage over its competitors, and the 130-seat baseline CS300 has an 18% cost advantage over similarly-configured Airbus and Boeing narrowbodies. Previously Bombardier has stated the CSeries would supply a 15% cost advantage.
Dewar explains Bombardier achieved better aircraft performance through the joint definition phase as it integrated systems and received input from suppliers to help the airframer refine the aircraft's design.
As Bombardier enters detailed design phase for the CSeries, Dewar says that engine tests of the PW1000G scheduled to power the aircraft will start sometime this summer, declining to supply a specific timeframe for the testing.
