A new type of rocket engine that will propel the X-33 experimental launch vehicle was tested to full power for the first time Dec. 18. Initial test data indicates satisfactory engine performance throughout the test. After the test, visual inspection showed some minor pinhole-sized erosion isolated to the interior wall of one of the engine's 20 thrust cells. The erosion was within the normal range for development testing and will not preclude further testing. This was the last planned test for 1999.
Engine testing is scheduled to resume next year.
Once testing of the first engine has been successfully completed, two flight engines will be tested. After successful flight acceptance test of the engines, the two flight engines will be shipped to Lockheed Martin Skunk Works in Palmdale to be mounted on the X-33 vehicle. Next Launch A Lockheed Martin Athena 1 will launch the Kodiak Star mission for NASA and the Air Force no sooner than Saturday from Kodiak Island, Alaska.
