Trials Performed Ahead of Schedule

Boeing last week completed loads calibration testing of the first P-8A Poseidon test aircraft, two weeks ahead of schedule. Loads calibration is one of the prerequisites for the US Navy flight clearance process.

During the tests, up to 80 percent of the highest expected flight loads were applied to the aircraft's fuselage, horizontal stabilizers, vertical fin and wing structures. Completion of loads calibration ensures that test aircraft T-1 is ready for airworthiness testing, which will commence later this year.

"One of the reasons we were able to complete the tests ahead of schedule is that the team incorporated some new technologies which enabled us to capture more accurate and more usable data faster," said Mark Magnuson, Boeing P-8A Structural Development and Certification director. "We also completed a number of independent reviews of the test plan prior to the start of testing, in order to reduce risk."

One of the new technologies, optical photogrammetry, entailed installing small video cameras on the P-8A's leading and trailing edges and underneath the fuselage. The measurement system provided three-dimensional, real-time data.

The team now will restore T-1 to its flight configuration and perform additional systems tests prior to first flight.

The P-8A is built by a Boeing-led industry team that includes CFM International, Northrop Grumman, Raytheon, Spirit AeroSystems and GE Aviation. The team currently is assembling and testing the first five P-8As, based off Boeing's 737-800 commercial airliner.

The Navy plans to purchase 108 P-8A long-range maritime reconnaissance and anti-submarine warfare aircraft to replace its fleet of P-3C Orions. Initial operational capability is slated for 2013.

As ANN reported, last week the US State Department approved the sale of three P-8I derivatives to the Indian navy -- the first of what Boeing hopes will be more international orders for the surveillance plane.
