Sukhoi has carried out a rejected take-off test with its Superjet 100 aircraft, as well as an evacuation trial, as part of its certification effort for the type.

It used one of the flying prototypes, number 95003, for the rejected take-off, performed in co-operation with the Russian certification authorities.

Sukhoi says the test, an aborted take-off run under maximum braking, is the "most difficult" of the certification requirements.

"The braking speed parameters are set for the conditions of a hot-and-high airport, with maximum tailwind," it states, adding that the test aircraft weighed 45.9t and was travelling at over 160kt.

"The brakes at the beginning are worn down to minimum thickness [and] the tests are performed without thrust reversers."

Sukhoi says the aircraft travelled about 700m (2,300ft) after braking commenced.

Goodrich and Michelin supply the wheels, brakes and tyres for the twin-engined aircraft. Sukhoi says the undercarriage did not catch fire during the test.

Sukhoi used its first serial production airframe, number 95007, for the evacuation test, conducted in a hangar at the Moscow Zhukovsky flight centre.

It says that 98 volunteer passengers and five crew members escaped in 73s, easily meeting the 90s criteria. The test was carried out under the observation of European Aviation Safety Agency personnel.

"The results were evaluated through synchronised video recording from the passenger cabin and outside each of the two emergency slides," says Sukhoi. While the aircraft has four doors, only half are permitted to be used during the certification test.

Sukhoi says the two tests showed that the aircraft fully complied with European and Russian certification criteria.
