Bombardier has disclosed details of the minimum-unstick testing on the initial CSeries variant which it conducted at a regional airport in Kansas.
One of the CS100 prototypes, FTV4, performed the tests at Salina airport during May. The twinjet was fitted with a projecting bumper underneath the aft fuselage for the tests, which explore the minimum speed at which the CS100 can lift off at high nose attitude.
FTV4 project flight-test engineer Allan Smith says the test is “one of the most dangerous” because it requires the bumper to make contact with the runway surface as the aircraft accelerates.
