Assuming the ground test gives a green light, the 787 flight-test team must then perform another set of system tests and ground-taxi tests on Dreamliner No.

This award is one in a series of milestones for the F135 engine program, including exceeding 10,000 ground test hours as part of the system development and demonstration program; logging 59 successful flight tests and more than 75 flight test hours of the F135-powered CTOL F-35 aircraft; and completing 14 flights of the F-35B powered by Pratt & Whitney's F135 STOVL propulsion system.

Documents made public by the Air Force show base officials are preparing an environmental assessment in preparation for conducting flight and ground tests of aircraft equipped with lasers: up to 140 flight tests and 24 ground tests this year, growing to 394 flight tests with 24 ground tests in 2010.

amp; OSLO, Norway -- In an industry breakthrough, ARINC Incorporated and Telenor today announced they have successfully completed ground tests of a new mobile phone technology for use by passengers on commercial airlines.

Ground tests required before the jet can fly are progressing well.

Byline: pinto03 NASA has awarded Pratt & Whitney Rocketdyne a contract change to provide additional sea-level and simulated-altitude ground tests for the J-2X rocket engine.

The 20 or so test flights will begin while ground test work continues on the laser itself, which was fired for the first time last week at Edwards.

The delays on the new rocket are caused by software-integration problems, inaccurate designs resulting in parts that didn't match, and the failure of three ground tests of maneuvering the rocket in space, the Pentagon said.
