The transition effort from the US space program to multipurpose vehicles that have a quick turnaround time has reached a milestone, confirmed a federal agency, with the success of A series of 10 shots of a rocket engine According to a report published in the G2 Bulletin of Joseph Farah, the goal is, according to the Agency for Advanced Defense Research Projects, to evolve to a more overhead capability to launch payloads, such as satellites, on demand.
The agency said that she was using a main engine AR-22 Experimental Spaceplane, a variant of the main engine used in the Ace shuttle sp program, for the recent test. It was run twice over two weeks to establish the performance characteristics and turnaround processes for the record
Then the test – a series of 10 shots of a duration of at least 100 seconds – started.
240 hours.
"The 10 × 10 series of tests, with its succession of 10 long-lasting discrete shots in rapid succession, is unprecedented for large liquid propellant engines fueled by hydrogen," reports DARPA. "The test is an early check of one of the most critical subsystems of the Experimental Spaceplane program required to perform aircraft-type operations."
The tests were conducted at NASA's Stennis Space Center in Stennis, Mississippi. The goal of DARPA is to get there quickly and inexpensively, according to the specific orbit we want, at the time of our choice, "says Fred Kennedy
chief of the bureau of the tactical technology of DARPA
. In the future, we expect large constellations of small satellites, with a continuing need for replenishment to replace older systems and demonstrate new innovative capabilities. If successful, XSP will be a key element of this strategy, "he said.
