This video shows the VASIMR VX-200 during a 30 second firing of it's first stage, and a 15 second firing of it's second stage. www.AdAstraRocket.com The Astra Rocket Companys VASIMR® VX-200 rocket prototype reached its highly-coveted 200 kW maximum power milestone at 11:59 am (CST) September 30th 2009 in tests conducted at the companys Houston laboratory. The DC power trace actually exceeded the design requirement by 1 kW and exhibited the clear signature of a well established plateau at peak power. The achievement comes after an intense experimental campaign that began in April 2009 when the engine was fitted with a powerful low temperature superconducting magnet, a critical component that enables VASIMR® to process large amounts of plasma power. The electrical power processing is accomplished using high efficiency, 95%, solid state RF generators built by Nautel Ltd of Halifax, Canada. Demonstration of a 200 kW capability was required to validate, with full scale performance data, the design of the VF-200-1 already underway. The VX-200 turns out to exceed the expected power density of VF-200-1 by about 25%, so this is a robust demonstration of the technology. The VF-200-1 is the first engine that the company plans to fly in space, and it is presently working with NASA to effectuate inspace testing in late 2013 on the International Space Station (ISS). The total power processed by the engine is distributed between its two electromagnetic stages. The first, tested last ...
