Northrop Grumman to investigate anomaly after OmegA’s first rocket motor test

“What we noticed at this time was profitable take a look at,” stated Kent Rominger, Northrop Grumman’s vp and seize lead for the OmegA launch system.

WASHINGTON — Northrop Grumman on Thursday performed a full-scale static fireplace take a look at of the primary stage of OmegA, the corporate’s new rocket it’s creating for nationwide safety missions. Firm officers known as it a profitable take a look at though it appeared that one thing went unsuitable close to the top when sparks and burning particles have been seen popping out of the nozzle.

Greater than 12 toes in diameter and 80 toes lengthy, the primary stage fired for 122 seconds on the firm’s take a look at facility in Promontory, Utah. The static fireplace produced greater than two million kilos of most thrust — roughly the equal to that of eight-and-a-half jumbo jets. The take a look at verified the efficiency of the motor’s ballistics, insulation and joints in addition to management of the nozzle place, Northrop Grumman stated in an announcement.

“What we noticed at this time was profitable take a look at,” Kent Rominger, Northrop Grumman’s vp and seize lead for the OmegA launch system, instructed reporters at a information convention following the take a look at.

Rocket motors are examined at excessive and low temperatures, he stated. This take a look at was at a excessive temperature of 90 levels “so that you get just a little bit increased thrust,” Rominger stated. “It seems that every thing labored very effectively. On the very finish when the engine was tailing off, we noticed the aft exit cone, possibly a portion of it, doing one thing just a little unusual that we have to go additional look into.”

A big plume of black smoke seen through the take a look at was regular, Rominger stated. When a motor burns out on the bottom in exams, black smoke is predicted whereas in house it’s a a lot cleaner burnout.

Rominger wouldn’t verify whether or not a bit or items of the aft exit cone got here aside. “Now we have to dig into all that information, analyze it to see what occurred,” he stated. The nozzle in OmegA’s C600 first stage motor is a industrial nozzle that’s completely different than the one utilized by NASA’s House Launch System, he stated.

Michael Sanjume, chief of the Launch Enterprise Acquisition Division on the Air Pressure House and Missile Techniques Middle, stated the Air Pressure will work with Northrop Grumman to research the info. “We view this take a look at as an integral a part of the event course of,” stated Sanjume.

Rominger stated the work required to research the outcomes of Thursday’s take a look at is not going to have an effect on the deliberate schedule for a full-scale static fireplace take a look at of OmegA’s second stage. That take a look at ought to happen in August or September, he stated.

The primary flight of the OmegA rocket, scheduled for 2021, will make use of a C600 first stage and a C300 second stage rocket motor. The second flight of OmegA can have the C600 and C300 configuration, with the addition of two GEM63XLT strap-on rocket motors.

Final October, the U.S. Air Pressure awarded Northrop Grumman a $792 million Launch Service Settlement contract to finish the event of OmegA and the required launch websites. The corporate will compete within the Nationwide Safety House Launch Section 2 Launch Service Procurement competitors that’s now beneath means. The Air Pressure plans to pick two launch suppliers in 2020. The opposite contenders are Blue Origin, SpaceX and United Launch Alliance.
