Orbital ATK next-generation launch vehicle
 
Конечно, в основном испытание успешное, но промахнуться так с соплом при американском опыте как то неприлично. Но с причинами разберутся, скоростная видео съемка наверняка есть, телеметрия также. И может быть дело не в материале сверхзвуковой части сопла, а в возникших дефектах дозвуковой части сопла, правда сопло короткое и это маловероятно.

After spending more than 50 years supporting NASA’s human spaceflight programs, the Vehicle Assembly Building (VAB), a landmark at the agency’s Kennedy Space Center in Florida, is getting its first commercial tenant.

Northrop Grumman will assemble and test its new OmegA rocket inside the massive facility’s High Bay 2, one of four high bays in the building. Officials with NASA, Northrop Grumman and the U.S. Air Force gathered in High Bay 2 on Aug. 16 to celebrate the partnership with a ribbon-cutting ceremony attended by legislative representatives and spaceport employees.


From left to right, Kennedy Space Center Director Bob Cabana, Northrop Grumman Vice President and OmegA Capture Lead Kent Rominger, and Col. Thomas Ste. Marie, vice commander of the U.S. Air Force’s 45th Space Wing, cut the ribbon in High Bay 2.

The company also is modifying mobile launcher platform-3 (MLP-3) to serve as the launch vehicle’s assembly and launch platform. Both the VAB and MLP-3 were originally built for the Apollo Program and went on to enable the three-decade Space Shuttle Program. The VAB also will be the assembly site for NASA’s Space Launch System rocket, which will carry the Orion spacecraft on Artemis missions to the Moon.

“With OmegA, we truly are standing on the shoulders of the giants of space history,” said Kent Rominger, Northrop Grumman’s vice president and capture lead for the OmegA launch system, as well as a veteran of five space shuttle flights. “This event marks that partnership with [Kennedy] at this phenomenal spaceport.”

Northrop Grumman signed a Reimbursable Space Act Agreement with NASA for use of the facilities. The company is developing the OmegA rocket, an intermediate/heavy-class launch vehicle, as a part of a launch services agreement with the U.S. Air Force.

Kennedy has transformed from a government-only space launch complex to the nation’s premier multi-user spaceport. Today, the space center has more than 90 active agreements with private-sector partners, sharing its array of unique facilities and resources through partnerships with government and commercial organizations.

This latest agreement brings Northrop Grumman into the fold.

“We have a great partnership with Northrop Grumman; we have a great partnership with all our partners,” said Kennedy Space Center Director Bob Cabana. “It’s a great pleasure to be able to be here today and cut the ribbon after signing this historic agreement to utilize this awesome facility to support our nation’s space program.”

The addition of Northrop Grumman’s OmegA rocket to the stable of vehicles processed and launched from the spaceport continues a long legacy that defines the local community.

“This whole area has been home to innovation and the drive to be bolder,” said Col. Thomas Ste. Marie, vice commander of the U.S. Air Force’s 45th Space Wing. “These efforts, government and contractor, have fueled the economies and the imagination and, really, the spirit of this community that we like to call the Space Coast.”

Static Fire Test of GEM 63

Northrop Grumman will conduct a full-scale static fire test of the GEM 63, the company’s next generation of Graphite Epoxy Motor (GEM) family of strap-on boosters to support intermediate- and large-class space launch vehicles, in Promontory, Utah. This motor was developed in partnership with United Launch Alliance to support national security, science and commercial payload launches of its Atlas V vehicle starting in 2020. At 66 feet long, the 63-inch diameter motor will fire for approximately 100 seconds and produce approximately 359,000 pounds of thrust.

What: Full-scale test of the GEM 63

When: Thursday, October 10, 2019; 1:00 p.m. MDT/3:00 p.m. EDT

GEM 63 Rocket Motor QM-3 Static Test

Northrop Grumman

15 окт. 2019 г.

On October 10, we completed the third static test fire of our GEM 63 rocket motor that will be used as a direct replacement for the existing strap-on boosters on United Launch Alliance’s Atlas V rocket. Firing for approximately 101 seconds at our Promontory, Utah, site, the 63-inch diameter motor satisfied additional requirements by the U.S. Air Force.

Solid rocket motor test-fired for Atlas 5 debut next year
October 20, 2019 | Stephen Clark

A new solid rocket motor built by Northrop Grumman has aced its final test-firing before a scheduled debut on a United Launch Alliance Atlas 5 rocket flight next year.

Northrop Grumman’s GEM 63 solid rocket motor will replace the Aerojet Rocketdyne AJ-60A solid-fueled booster that has flown on Atlas 5 rockets since 2003.

Billed as a “direct replacement” for the AJ-60A, Northrop Grumman’s GEM 63 booster produces roughly the same thrust and has approximately the same dimensions as the Atlas 5’s incumbent solid-fueled boosters.

Northrop Grumman performed the third in a series of GEM 63 test-firings Oct. 10 at the company’s Promontory, Utah, site before the new solid rocket motor’s first launch on an Atlas 5 rocket from Cape Canaveral late next year.

Kendra Kastelan, a Northrop Grumman spokesperson, said the company has no further test-firings planned for the GEM 63 motor before its first launch.

A spokesperson with the U.S. Air Force’s Space and Missile Systems Center, which procures launch services for U.S. military and intelligence-gathering satellites, said the the first use of the GEM 63 solid rocket booster on an Atlas 5 mission is scheduled for September 2020.

The mission, codenamed NROL-101, will launch a classified payload for the National Reconnaissance Office, which owns the government’s top secret spy satellites, the Air Force spokesperson confirmed to Spaceflight Now. Five GEM 63 boosters will help the Atlas 5’s main engine propel the NROL-101 payload into space, an Atlas 5 configuration with a 5-meter (17-foot) fairing known as the Atlas 5-551.

The GEM 63 motor is an enlarged version of the GEM 60 booster built by Northrop Grumman for ULA’s Delta 4 rocket family. The last GEM 60 motor flew on a Delta 4 launch in August. ULA’s five remaining Delta 4 missions will launch in the rocket’s heavy-lift configuration with three liquid-fueled cores, and no strap-on solid rocket boosters.

Northrop Grumman, through its predecessors ATK and Orbital ATK, also supplied smaller boosters — called Graphite Epoxy Motors — for the now-retired Delta 2 and Delta 3 rocket families.

The new motor is designated the GEM 63 because of its 63-inch (1.6-meter) diameter. It measures 66 feet (20 meters) long and will generate up to 373,800 pounds of thrust during launch, consuming some 97,500 pounds (44.2 metric tons) of pre-packed solid propellant during a burn lasting around 100 seconds, before the booster is jettisoned.

Like the AJ-60A motor, the GEM 63 will have fixed nozzles and ogive nose cone, providing the proper aerodynamic shape to ensure the booster cleanly falls away from the Atlas 5 after burnout.

ULA’s ground processing team rehearsed transportation, handling and mating procedures using an inert GEM 63 motor at the Atlas 5 launch pad in May. The team practiced installing the inert motor on an Atlas 5 first stage inside the Vertical Integration Facility at Cape Canaveral’s Complex 41 launch pad to verify clearances and techniques before working with a real GEM 63 motor next year.

Tory Bruno, ULA’s president and CEO, wrote on Twitter that all Atlas 5 missions will eventually convert over to the new GEM 63 motor. ULA has not said when the company’s inventory of AJ-60A boosters will run out, or identified the final launch with Aerojet Rocketdyne-built solid rocket motors.

Crewed launches with Boeing’s CST-100 Starliner spacecraft will also eventually switch over to the GEM 63 booster, Bruno tweeted in response to a question from Spaceflight Now.

Aerojet Rocketdyne’s AJ-60A motor has a flawless record since its first use on the Atlas 5’s third launch in July 2003, with 115 of the boosters flown to date.

ULA announced in 2015 the selection of Orbital ATK — now part of Northrop Grumman — to provide solid rocket boosters for future Atlas 5 launches, and for the next-generation Vulcan Centaur rocket. At the time, ULA said the selection of the GEM 63 rocket motor would “significantly lower the price to ULA and to the U.S. government.”

A lengthened version of the GEM 63 known as the GEM 63XL will fly on ULA’s new Vulcan Centaur rocket, which is scheduled for an inaugural launch in 2021. The Atlas 5 rocket can fly with any number of solid rocket boosters from zero to five, while the Vulcan Centaur will launch in standardized configurations with two or six strap-on motors alongside the rocket’s two Blue Origin BE-4 main engines.

Northrop Grumman’s planned OmegA launcher, which is competing with ULA’s Vulcan Centaur for Air Force contracts, is designed to fly with up to six GEM 63XLT strap-on boosters, another variant of the new GEM 63 solid rocket motor.
