Aerojet Announces Successful Requalification of Its Delta II AJ10-118K Second
SACRAMENTO, Calif., March 14, 2013 (GLOBE NEWSWIRE) -- Aerojet, a GenCorp
(NYSE:GY) company, announced that its Delta II second stage engine, the
AJ10-118K, successfully passed a requalification test of its ablative chamber
at Aerojet's J4 altitude simulation test facility in Sacramento.
The intent of the requalification program was to replace the asbestos
insulator material with a readily-available and environmentally-friendly
alternative. The three-burn hot fire test simulated a "test-like-you-fly" duty
cycle configuration, qualifying the new engine configuration for flight. The
altitude test was preceded by a successful sea-level test in November 2012.
"The Delta II is one of the most robust and reliable rocket engines ever
flown," said Aerojet Vice President of Space and Launch Systems Julie Van
Kleeck. "This test represents another successful milestone in a program with a
rich history of successful milestones and 100 percent mission success.
Additionally, it verifies that the past design rigor put into this heritage
technology meets and exceeds the scrutiny of modern day expectations for
Under contract to United Launch Alliance, Aerojet's AJ10 has provided
second-stage propulsion on 151 Delta II flights to date with a 100 percent
success rate. The engine has helped deliver payloads for NASA's space
exploration efforts such as the Phoenix Mars Lander, Mars Polar Lander, Deep
Impact, Kepler, NEAR Shoemaker and the Mars Exploration Rovers, Spirit and
Opportunity, as well as the U.S. Air Force Global Positioning System Block IIR
The AJ10 second stage engine produces approximately 10,000 lbs. of thrust for
orbital insertion. There are currently four flights in the near-term manifest
for Delta II, two in 2014 and two in 2016.
