Aerojet Rocketdyne completes first rocket engine for DARPA’s quick launch rocket
Aerojet Rocketdyne has completed assembly of the first rocket engine for DARPA’s quick launch rocket, Phantom Express, being built by Boeing.
[The engine] can fly for 55 missions with servicing only every 10. To speed up turnarounds, the engines will be installed in a hinged nacelle for better access and the entire spacecraft will use an operations procedure similar to those developed for aircraft.
The first AR-22 engines will be used for daily hot-fire tests at Rocketdyne’s Stennis Space Center facility in Mississippi to demonstrate that it can handle multi-mission conditions and that the fast turnarounds are both feasible and practical. In addition, Rocketdyne says that the test information will help spaceplane builder Boeing to improve the Phantom Express ground infrastructure.
Boeing and Aerojet Rocketdyne both have it very sweet. They have gotten DARPA to fund the development of their own low-cost reusable rocket, while other private companies have to go it alone.
Still, it appears that Boeing is leveraging its engineering experience from building the X-37B for the Air Force for this project. Whether the company can expand the rocket’s customer base beyond the Air Force remains unclear.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
