Bombardier plans to “clean up” its CRJ regional jet to gain further efficiency improvements, says the programme’s general manager Sylvain Leclerc.
The “aerodynamic clean-up” includes putting a cap on the tail bumper, closing a roughly 2.5cm (1in) gap between the tail and rudder, introducing the carbon break on the CRJ900 from the CRJ1000 and using lighter-weight materials throughout the aircraft, says Leclerc.
Bombardier is displaying an American Airlines CRJ900 at the Farnborough air show.
Just the tail bumper cap and closure of the gap between the tail and the rudder combined could reduce fuel burn by up to 0.5%, says Leclerc.
“Continuous improvement is the key,” he says. “You don’t change a working formula: you keep improving it.”
Bombardier introduced an enhanced CRJ900 that burns 5.5% less fuel than the first-generation CRJ900 with the debut delivery to American Airlines in June. The improvements are through weight reductions and new nozzles.
The airframer has outstanding firm orders for just 105 CRJ aircraft, including CRJ700s, CRJ900s and CRJ1000s, Flightglobal’s Ascend Fleets database shows. This compares with 245 outstanding firm orders for Embraer’s competing line of E-Jets, not including the re-engined E2 E-Jets.
