Boeing 787 undergoes its pre-flight "high-blow" test

BOEING is inching closer to the long-overdue first flight of its 787....with the successful completion of the "high blow" high-pressure test on the static test airframe...

The high blow test is one of three static tests that must be cleared before the first flight....

During the high blow test, air pressure in the airframe was increased to an internal pressure of 150 per cent of the maximum level expected in service: 14.9lb per square inch (1.05kg/cm) gauge.

"Still, it's very rewarding to see a whole airplane being tested and having the results we expected," he said.

The static test fuselage is one of two aircraft being used to verify the structural integrity of the 787.

The aircraft is enclosed in a 700 tonne test rig that looks more like a medieval torture chamber, where it will undergo the most comprehensive testing program ever for a Boeing commercial aircraft except for the original 737, which involved the validation of a new -- at the time -- computer design tool.

A typical test rig has 100 hydraulic actuators to apply stress to the aircraft, with 4300 gauges to measure the effect of the stress.

I know what he means. I have the same feeling every time a plane I am traveling on lands safely.
