AJ26-59: NK-33 modified by Aerojet Rocketdyne. Planned to be used on the Kistler K-1, but the project was cancelled and the engine was never flown. AJ26-62: NK-33 modified by Aerojet Rocketdyne with additional gimbal mechanism. Used on the Antares 100-series first stage. NK-33A (GRAU index 14D15): Refurbished NK-33 used on the Soyuz-2.1v first ...
NASA Review of Orbital ATK Accident Released, NASA "The team determined the proximate cause of the Antares launch vehicle failure was an explosion within the AJ-26 rocket engine and identified three credible technical root causes, any one or combination of which could have resulted in the engine failure. The team outlined six technical findings and made seven recommendations to address those ...
Aerojet's AJ26 engine is an oxidizer-rich, staged-combustion LO2/Kerosene engine that achieves very high performance in a lightweight compact package.
AJ26 is a rocket engine used by Orbital Sciences Corporation for its commercial cargo missions to the International Space Station. NASA conducted a hotfire test of AJ26 engine E-15 at Stennis Space Center on Jan. 17, 2014, and cleared it for shipment to Wallops Flight Facility.
A team of NASA, Aerojet Rocketdyne, Orbital Sciences and Lockheed Martin engineers put each AJ26 engine through acceptance testing on the E-1 test stand at the Stennis Space Center in southern ...
The AJ26 engine used for Antares is based on a Russian NK-33 rocket engine designed and manufactured in the early 1970s in support of the failed Russian N-1 moon program. Aerojet-Rocketdyne modifie…
Aerojet 's AJ26 engine is an oxidizer-rich, staged-combustion LO2/Kerosene engine that achieves very high performance in a lightweight compact package. Based on the NK-33 engine originally designed and produced in Russia for the Russian N1 lunar launch vehicle, the liquid-fuel AJ26 will provide boost for the first stage of the Antares rocket.
The two Aerojet AJ26 engines, which form the Antares rocket's first-stage main engine system, burned for 233 seconds and provided 816,000 lbs of vacuum thrust as it powered Antares from the ...
The AJ26 engine used in the testing was removed from the E-1 stand on Jan. 24, and will be returned to Aerojet in Sacramento, Calif. to be refurbished and used on an upcoming Taurus II mission. The same day the engine was removed, the first flight engine was installed to begin regularly planned "acceptance testing" at Stennis.
