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."

ЦитироватьSolid 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.

ЦитироватьOmegA Rocket: Counting Down to 2021 Launch

 Northrop Grumman

18 окт. 2019 г.

The powerful OmegA rocket is a top priority for Northrop Grumman, and we are counting down to launch in 2021.

OmegA has the thrust needed to launch intermediate/heavy national security missions as well as satellites for civil and commercial customers.
The United States Air Force, Northrop Grumman and suppliers across the U.S. are partners in developing and manufacturing OmegA. Scientists, engineers and expert technicians are building and testing flight hardware and ground system equipment for OmegA's first flight.

Milestones featured in this video:
• Successfully completed full scale static test of first stage
• Set up friction stir welding operations at NASA's Michoud Assembly Facility
• Began working in the Vehicle Assembly Building at NASA's Kennedy Space Center
• Started making modifications to Mobile Launch Platform 3
• Completed winding and cure for the first stage cases for OmegA's first flight
• Assembled the first flight set of upper stage engines

Northrop Grumman designed the OmegA rocket specifically to address performance, schedule, ride quality and reliability needs of national security payloads. It uses highly reliable solid fuel for the boost phases of launch. OmegA's cryogenic upper stage uses two proven RL10 engines. Its avionics have flown on more than 100 missions with 100 percent success. Leveraging existing facilities, technologies with high technical readiness levels and an experienced workforce keeps OmegA affordable for a wide range of missions.

Northrop Grumman is excited about several innovative ways we will evolve the design over the next few years to achieve even greater performance.

ЦитироватьOmegA rocket will launch up to two NationSats for Saturn Satellite Networks on certification flight for the US Air Force NSSL program in spring 2021
December 12, 2019

DULLES, Va. – Dec. 12, 2019 – Northrop Grumman Corporation (NYSE: NOC) announced that Saturn Satellite Networks has selected the OmegA space launch vehicle to launch up to two satellites on the rocket's inaugural flight scheduled for spring 2021. OmegA will launch fr om Kennedy Space Center's Pad 39B and ins ert the SSN satellites in to a geosynchronous transfer orbit.

"The OmegA rocket expands Northrop Grumman's launch capabilities beyond our small and medium class rockets, which have successfully launched nearly 80 missions," said Scott Lehr, vice president and general manager, flight systems, Northrop Grumman. "Expanding the company's launch capabilities to the intermediate/heavy class with OmegA complements our national security satellite portfolio and enables us to better support our customers."

Jim Simpson, CEO of Saturn, said, "We are excited to launch Saturn's NationSat on Northrop Grumman's OmegA launch vehicle's inaugural mission. OmegA's performance, payload accommodations, and rigorous certification program assures us it is a great fit for NationSats and our customers."

Last October, the U.S. Air Force awarded Northrop Grumman a $792 million Launch Services Agreement to complete detailed design and verification of the OmegA launch vehicle and launch sites.

"The first flight of OmegA is a key step in our certification process for the U.S. Air Force National Security Space Launch program," said Charlie Precourt, vice president, propulsion systems, Northrop Grumman. "Having Saturn's NationSat on board for this mission further demonstrates the versatility of OmegA to serve other markets including commercial and civil government."

Precourt continued, "Our customer's mission comes first, whether OmegA is launching a commercial satellite or a national security payload. At the end of the day, we deliver the customer's spacecraft wh ere it needs to go."

"Northrop Grumman designed OmegA to use the most reliable propulsion available—solid propulsion for the boost stages and flight proven RL10 engines for the upper stage—to ensure exceptional mission assurance for our customers," Precourt added. "Northrop Grumman's technical expertise is both broad and deep, and we bring unmatched experience, stability and a strong customer focus to every partnership."

OmegA rocket's first customer still needs customer of its own
by Caleb Henry — December 16, 2019

WASHINGTON — Startup satellite builder Saturn Satellite Networks says it doesn't have a customer lined up for the small geostationary spacecraft it booked aboard the inaugural launch of Northrop Grumman's OmegA rocket, but reserved the 2021 mission to save time down the road.  

Northrop Grumman announced Dec. 12 that Saturn agreed to launch one or two of its NationSat line of small geostationary communications satellites on the maiden flight of OmegA, a solid-fueled rocket Northrop Grumman is building to compete for U.S. national security missions.

Saturn CEO Jim Simpson said making the OmegA launch reservation before it has customers locked down for the NationSat spacecraft OmegA would carry is part of the startup's strategy for providing a one-stop-shop for its target customers.

"Part of our objective is to provide delivery in orbit of our satellite systems," Simpson said in a Nov. 12 interview. "As such, it's very incumbent upon Saturn to secure multiple launch options to give customers multiple alternatives at the lowest possible cost."

Saturn formed earlier this year to build small geostationary satellites for customers that can't afford or justify a traditional, multiton communications satellite. It considers small nations ideal customers.

Saturn's first NationSat satellite, for Moscow-based Intersputnik, is slated to launch on a shared SpaceX Falcon 9 mission that has slipped from 2020 to 2021.

Simpson said Saturn will retain ownership of the satellite, but will lease the capacity to Intersputnik for the lifetime of the spacecraft. Simpson said Saturn will provide lifetime capacity leases or full ownership of satellites depending on customer preference and regulatory restrictions.

Simpson said Saturn is close to clinching a second NationSat customer it expects to announce early next year. Whether that second NationSat will be assigned to OmegA or another rocket is to be determined, he said.

Saturn is offering NationSats as both single-operator satellites and so-called condosats shared by multiple operators.

Northrop Grumman is counting on Saturn to fill one of two certification flights it needs to fly to qualify OmegA for U.S. national security launches, said Charlie Precourt, Northrop Grumman's vice president of propulsion systems. He said Northrop Grumman has a backup plan for those flights if Saturn's satellites don't come through in time, but he declined to discuss specifics.

"Those are details that we've worked with them behind the scenes," Precourt said. "But our first focus is with the Air Force."

Northrop Grumman's primary focus with OmegA is the U.S. military market, having received a $792 million Launch Service Agreement from the Air Force last year meant to cultivate more launch options for the National Security Space Launch program.

The Air Force expects to sel ect two launch providers next year, choosing among Northrop Grumman, SpaceX, Blue Origin and United Launch Alliance for launch contracts anticipated to be worth billions of dollars collectively.

Whether Northrop Grumman continues development of OmegA will be heavily influenced by the Air Force's downselect.

Simpson said Saturn is aware of that risk.

"[That] is why we want to have multiple launch options to provide our customers," he said. "No one wants to be reliant on one launch vehicle."

Precourt said Saturn and Northrop Grumman have a contingency plan if OmegA is canceled.

"Suffice it to say that's been contemplated and we're dealing with it," Precourt said, without elaborating.

Precourt said Northrop Grumman plans to use the Saturn launch as one of two certification flights to qualify the rocket for U.S. national security launches.

"We're targeting somewhere in the first part of 2021 for that first flight and we'll be right on the heels of it as quickly as we can with the second," he said.

Precourt said Northrop Grumman keeps OmegA costs down by using the same factories and much of the same launch infrastructure as its smaller Antares rocket and NASA's Space Launch System, a Boeing-led heavy-lift rocket with side-mounted solid rocket boosters supplied by Northrop Grumman. He said OmegAs price is "competitive," but would not give a specific figure.

Simpson said his experience at Aerojet Rocketdyne, which supplies engines for United Launch Alliance rockets and Northrop Grumman's OmegA, convinced him that any rocket the U.S. military chooses will be reliable for commercial customers as well.

"It provided us a lot of confidence that the launch vehicle would have all of the criteria that we would like to see in a launch vehicle tested prior," he said. "That's why we were excited about having OmegA as part of our launch vehicle options, because of the rigor that's involved in being part of the NSSL program."

Simpson said Saturn's NationSats are small enough to fit on secondary payload adapters. Originally sized between 600 and 1,700 kilograms, Simpson said the largest NationSats will now be around 1,000 kilograms due to a decision to use electric propulsion instead of chemical.

Simpson said Saturn anticipates forming more placeholder launch agreements over the next 12 months.

OmegA on track to support certification launch in 2021

February 27, 2020

PROMONTORY, Utah – Feb. 27, 2020 – Northrop Grumman Corporation (NYSE: NOC) successfully conducted a full-scale static fire test of the second stage of its OmegA rocket today in Promontory, Utah. Developed to support the U.S. Space Force's National Security Space Launch program, the OmegA Launch System remains on track for its first certification flight in spring 2021.



During today's test, the second stage motor fired for full-duration, approximately 140 seconds, burning nearly 340,000 pounds of solid propellant to produce upwards of 785,000 pounds of thrust. The test verified the motor's ballistics and thermal performance as well as steering control and performance in a cold-conditioned environment. The test team collected more than 500 channels of data to aid in verifying the motor.

"Northrop Grumman designed OmegA to use the most reliable propulsion available to ensure exceptional mission assurance for our customers," said Charlie Precourt, vice president, propulsion systems, Northrop Grumman. "Today's firing is a significant accomplishment that demonstrates a domestic solution for the RD-180 rocket engine replacement."

In October 2018, the U.S. Air Force awarded Northrop Grumman a $792 million Launch Services Agreement to complete detailed design and verification of the OmegA space launch vehicle and launch sites. Today's cold test, in conjunction with the successful hot static fire in May 2019, subjected OmegA's motors to the most extreme propellant temperatures the rocket will experience during storage, transport, stacking and launch.

Northrop Grumman has leveraged its flight proven technologies and extensive experience launching critical payloads in the development of the OmegA launch system. The rocket was designed to accommodate national security payloads while also serving the civil and commercial markets.

In preparation for OmegA's inaugural flight, Northrop Grumman now occupies High Bay 2 as the first commercial tenant in NASA's historic Vehicle Assembly Building at Kennedy Space Center. Construction crews are currently modifying Mobile Launch Platform-3 to serve as OmegA's assembly and launch platform at Pad 39B.

Northrop Grumman solves the toughest problems in space, aeronautics, defense and cyberspace to meet the ever evolving needs of our customers worldwide. Our 90,000 employees define possible every day using science, technology and engineering to create and deliver advanced systems, products and services.
