DULLES, Virginia 23 January 2018 (Orbital ATK PR) – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, has entered into a contract with the Defense Advanced Research Projects Agency (DARPA) to study potential integration of turbine and hypersonic engine technologies into a new aircraft propulsion system under DARPA’s Advanced Full Range Engine (AFRE) program.
SACRAMENTO, Calif., Oct. 09, 2017 (Aerojet Rocketdyne PR) — Aerojet Rocketdyne, Inc., a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), has entered into an agreement with the Defense Advanced Research Projects Agency (DARPA) to develop and ground test an innovative propulsion system under the agency’s Advanced Full Range Engine (AFRE) program.
Ah, yeah…about that….Maybe if Virgin Galactic was already in powered flights. As it is, they still have at least one more glide flight to conduct. And they haven’t conducted one of those in two months.
It’s possible they only get one powered flight test off the ground by the end of the year. Would that leave them prepared to begin commercial flights by April? Probably not. There are a lot of variables involved — number of test flights, pace of testing, problems they discover — but six months would be pushing it.
The morning of Dec. 3, 2016, began like so many others in Mojave. The first rays of dawn gave way to a brilliant sunrise that revealed a cloudless, clear blue sky over California’s High Desert.
This was hardly newsworthy. For most of the year, Mojave doesn’t really have weather, just temperatures and wind speeds. It had been literally freezing overnight; the mercury was at a nippy 28º F (-2.2º C) at 4 a.m. As for Mojave’s famous winds – an enemy of roofs, trees and big rigs, but the lifeblood of thousands of wind turbines that cover the landscape west of town – there really weren’t any. It was basically a flat calm.
DARPA has awarded a contract worth $21.4 million to Orbital ATK for a research project under the Advanced Full Range Engine (AFRE) program. The defense agency is allocating $1 million in R&D funds for the program in fiscal year 2017, which ends on Sept. 30.
“AFRE seeks to develop and demonstrate a new aircraft propulsion system that could operate over the full range of speeds required from low-speed takeoff through hypersonic flight,” DARPA said in a press release announcing the program.
Hypersonic speeds are defined as Mach 5 (approximately 3,300 miles per hour/5,300 kilometers per hour) and above.
“Instead of designing an entirely new kind of engine, we’re envisioning an inventive hybrid system that would combine and improve upon the best of off-the-shelf turbine and ramjet/scramjet technologies,” said Christopher Clay, DARPA program manager. “This won’t be the first time that ambitious engineers will attempt to combine turbine and ramjet technologies. But with recent advances in manufacturing methods, modeling, and other disciplines, we believe this potentially groundbreaking achievement may finally be within reach.”

SATISH DHAWAN, India (ISRO PR) — In the quest to reduce the cost of access to space and to extend the frontiers of space exploration, ISRO has ventured into Reusable Launch Vehicle (RLV) and Re-entry missions, Air-breathing propulsion technology demonstration and Interplanetary missions. These missions encounter design criticalities at Hypersonic Mach number regime and need rigorous aero-thermodynamic characterisation at these Mach numbers.
In order to cater to the above need, Industrial type Hypersonic Wind Tunnel and Shock Tunnel have been established at Vikram Sarabhai Space Centre (VSSC).
Although orbital launch vehicles get all the glory (and infamy when they fail), 2016 was also a busy year for the far less glamorous suborbital launch sector. There were 19 suborbital launches at various sites around the world, and two more sounding rocket launches of note where the payload didn’t go above 100 km. (more…)
During an appearance in Florida one week before the election, Republican vice presidential candidate Mike Pence promised that he and Donald Trump would reinvigorate the nation’s space program.
However, the incoming administration’s larger economic priorities are likely to limit its options for any large-scale space exploration efforts.
President elect Trump’s biggest priority is a massive tax cut that would primarily favor corporations and upper income Americans. It would also lower taxes slightly for many middle class families while actually raising taxes for some of them. CBS News has a full analysis. Some of the highlights:
Right now, a single parent with $75,000 in income and two children can claim a head of household deduction of $9,300, plus three personal exemptions. Those steps would reduce the household’s taxable income by $21,450, to $53,550. (more…)
Two senior policy advisers to Donald Trump, Robert S. Walker and Peter Navarro, published op-eds in SpaceNews prior to the election outlining the president elect’s planned civil and military space policies.
Civil Space Policy
The highlights on the civil side include:
“Public-private partnerships should be the foundation of our space efforts. Such partnerships offer not only the benefit of reduced costs, but the benefit of partners capable of thinking outside of bureaucratic structures and regulations.”
OK, that seems to have pretty broad acceptance and is along the lines of what’s already being done. (more…)
Donald Trump policy advisers Robert Walker and Peter Navarro have returned to the pages of SpaceNews with a second op-ed piece the Republican presidential candidate’s military space policy.
They start out rather bizarrely by citing the weakness of the Obama-Clinton economy, advancing the startling proposition that economic policy is within the purview of a secretary of state who left the administration in early 2013. They then invoke Ronald Reagan and promise that Trump will bring peace through strength by countering aggressive moves by Russia and China.
Trump administration will simultaneously strengthen our economy and manufacturing base while significantly expanding our civilian and military space budgets. Trump understands, as Reagan did before him, that without a strong economy, there can be no strong space program. It is not too bold to assert the maintenance of our technological and strategic superiority in space is vital not just to national security but to our very survival….
While America’s space-based capabilities have made our military the world’s most powerful and effective, an over-reliance on our satellite network to provide situational awareness on the battlefield is now making America highly vulnerable to attack. Chinese and Russian strategists understand this better than our own government. That’s why they are now aggressively targeting our satellite networks – both military and civilian as the very concept of warfare broadens.
Against this emerging strategic chessboard, Donald Trump’s priorities for our military space program are clear: We must reduce our current vulnerabilities and assure that our military commands have the space tools they need for their missions. We must also reduce the cost of space access and create new generations of satellites to deal with emerging threats….
A Trump administration will also lead the way on emerging technologies that have the potential to revolutionize warfare. For example, both China and Russia are aggressively moving forward with a range of hypersonic weapons that are very difficult to defend against with traditional air-defense interceptors. A Trump administration will increase the coordination between DARPA, NASA, and the private sector to ensure the U.S. remains well ahead of the technology curve.
DULLES, Va., January 18, 2016 (Orbital ATK PR) — Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, announced today that it has successfully tested a 3D-printed hypersonic engine combustor at NASA Langley Research Center. The combustor, produced through an additive manufacturing process known as powder bed fusion (PBF), was subjected to a variety of high-temperature hypersonic flight conditions over the course of 20 days, including one of the longest duration propulsion wind tunnel tests ever recorded for a unit of this kind. Analysis confirms the unit met or exceeded all of the test requirements.
Sir Richard has invited the theoretical physicist and cosmologist Stephen Hawking to name the new plane at the unveiling. He has already offered the scientist Virgin Galactic’s only free ticket into space – which Professor Hawking has accepted, provided his health allows it.
“Obviously, we had a year’s delay after the accident and it’s tremendous that Stephen Hawking has agreed to come and name the new spaceship,” Sir Richard said.
“He has made it very clear that he thinks mankind and womankind need to work very hard to try to colonise other planets and that space is very important for people back here on Earth,” he said.
Hawking has a free ticket on SpaceShipTwo which now costs a cool $250,000 (up from $20o,000 in 2013). The PR benefits of having the world-famous physicist involved in the roll out ceremony is probably well worth the cost. And it’s the least Hawking can do for such a generous gift.
“We are doing everything we can to try to work towards turning the world into a place that’s run by clean energy, not dirty energy. We’ve managed to reduce the amount of energy, of carbon output, to get somebody into space … to less than a round-trip, economy class, from London to New York,” he said. (more…)

ARNOLD AIR FORCE BASE, TENN., July 3, 2014 — The relationship between the Air Force Research Laboratory and Arnold Engineering Development Complex’s hypervelocity capabilities is paying dividends and leading to a more in-depth and scientifically broader collaboration.
In light of the success of several joint projects, AFRL leadership has decided to extend the organization’s partnership with AEDC by establishing a new hypersonic research branch, to be known as the High Speed Experimentation Branch, here.
Virgin Group Founder Richard Branson was on CNBC’s Squawk Box the other day talking up his plans to follow up Virgin Galactic’s suborbital space tourism flights with hypersonic point-to-point transcontinental commercial passenger service.
