Rolls-Royce backs hypersonic-power specialist Reaction Engines with new investment
By: Andrew Chuter
LONDON – Rolls-Royce has formed a strategic partnership with British hypersonic-power experts Reaction Engines and is backing that up with a new investment in the company.
The new partnership is aimed at developing high-speed propulsion systems for defense and civil applications as well as exploring Reaction Engines' key thermal management technology as part of Rolls-Royce's own gas turbine engines and hybrid-electric systems.
Rolls-Royce will invest £20 million ($26 million) over the next two years, building on an initial equity investment made in 2018. Other investors like BAE Systems, Boeing Horizon-X and financial institutions could follow suit, said a Reaction Engines spokesman.
The announcement comes as Rolls-Royce steps up its interest in supersonic flight.
Earlier in August, Virgin Galactic revealed a delta-winged Mach 3 sub-orbital vehicle concept powered by Rolls-Royce.
Earlier this year the British engine builder said it was collaborating with the U.S. company Boom Aerospace on propulsion options for a Mach 2.2 airliner called Overture.
“We have been working closely with Reaction Engines for the past two years, including exploring the potential of high-Mach systems for defense applications, and I am delighted that we are able to strengthen that relationship,” said Mark Thompson, director of global strategy and business development at Rolls-Royce.”
“Reaction Engines' thermal-management skills, added to our suite of existing technologies and capabilities, will further assist us as we explore opportunities in supersonic and hypersonic aviation,” Thompson added.
The two companies have also been involved with BAE and the UK Ministry of Defence in the first phase of a contract related to high-Mach advanced propulsion systems which could eventually find their way on to the British Tempest sixth-generation combat aircraft development.
Aerospace and defense consultant Howard Wheeldon, of Wheeldon Strategic Advisory, said the tie-up demonstrated the determination of both companies to be at the forefront of high-speed engine development going forward.
“The future of aerospace development from here on is about creating greater efficiency of operation and sustainability. Speed, including supersonic and hypersonic aviation development, will be an important part of this, and high-Mach advanced propulsion systems combined with the potential to apply some of the developed Reaction Engines technology within existing gas turbine engines together with what this offers for future hybrid-electric systems is of huge importance to a world-leading aerospace company such as Rolls-Royce,” he said.
Reaction Engines CEO Mark Thomas said the partnership will help speed commercialization of the technology.
“This strategic partnership is about developing market-ready applications for Reaction Engines' technology in next-generation engines and is a significant step forward for our technology commercialization plans,” said Thomas.
Based at Culham, southern England, and with a test site at Denver, Colorado, Reaction Engines has been developing technology to power aircraft and rockets at supersonic and hypersonic speeds of Mach 5 and above – more than twice the speed of the Concorde.
Last October Reaction Engines announced its key lightweight air cooling technology had been tested at its Colorado facility as part of the Defense Advanced Research Projects Agency's HTX project.
At the time Reaction Engines said its heat exchanger had been exposed to hypersonic conditions approaching 1,000 degrees centigrade (1,800 degrees F).
The heat exchanger performed its precooler function by quenching about 1,800-degree Fahrenheit temperatures in less than one-twentieth of a second.
Wheeldon said the Colorado test was a significant step in the development of Reaction Engines' SABRE rocket engine program.
“As an enabling technology for a potentially large range of other precooled propulsion systems that have potential commercial applications, the successful testing last year by Reaction Engines of its precooler heat exchanger at airflow temperatures conditions representing Mach 5 was a significant milestone in the development of its revolutionary SABRE air-breathing rocket engine. The new strategic partnership with Rolls-Royce offers further the commercial opportunities and potential for both companies,” said Wheeldon.
SABRE, which stands for Synergetic Air Breathing Rocket Engine, is a propulsion system being developed to operate in air breathing and rocket modes using the pre-cooler technology.

French Air Force chief: France and Germany working on export controls for future fighter
By: Valerie Insinna WASHINGTON — The French Air Force chief of staff provided top cover for the future Franco-German fighter at a time when the French defense industry is increasingly concerned that cooperation with Germany could curtail its ability to export the system. “There is a real determination" at the highest levels of government — including French President Emmanuel Macron and German Chancellor Angela Merkel — to agree on export controls, said Gen. Philippe Lavigne during a Feb. 7 roundtable with reporters. "It's a need for our security, but it's also a need for our industry, and we have to develop this,” he said, adding that Spain has already signed on as an observer to the program and that others are expected to follow. The French government is generally seen as more supportive of arms sales than its partner in the sixth-generation fighter program, called the Future Combat Air System, or FCAS. While enthusiasm for the program remains high, some French defense industry officials are concerned that Germany's involvement could prevent sales to countries that Berlin considers rogue actors. But settling an export policy is just one of the many questions about the FCAS program that are still yet to be answered. So far, France and Germany's concept for FCAS involves a network of swarming UAVs, new weapons and a sixth-generation fighter that can exchange information with each other. FCAS would replace France's Rafale and Germany's Eurofighter around 2040. “We haven't decided what will be the architecture,” Lavigne said. “Will it be this type of aircraft? Will it be this type of [UAV]? Will it be this type of unmanned combat air vehicle? Will it be this type of missiles? But we know that we will share an architecture. “The gamechanger is the connectivity between different platforms.” Earlier this week, the French and German governments awarded €65 million (U.S. $74 million) to Dassault and Airbus for the two-year study that will solidify a path forward for FCAS, and the companies plan to announce demonstrator programs at the Paris Air Show this summer. Lavigne wasn't clear on how the governments would reconcile different requirements, like France's intention to launch FCAS from aircraft carriers, which could drive different design attributes than a fighter that takes off and lands conventionally. “Of course we will have national interests in France with the nuclear deterrence. Germany will have different national interests,” he said. However, he stopped short of saying how much commonality is expected between the two militaries. Until the study is complete, it is “too early to say” whether FCAS will be manned or unmanned. However, Lavigne said a human will continue to be in the loop — especially for nuclear deterrence missions — whether a human is in the cockpit or it is remotely piloted. “We are open to look at the technical solution,” he said. “For me, it's optionally piloted.” FCAS' system-of-systems approach is similar to the U.S. Air Force's vision for Penetrating Counter Air, its future air superiority concept. The Air Force hasn't shared which defense companies are involved in conceptualizing or prototyping future technologies that could be pulled into a PCA program of record, but it requested $504 million in fiscal 2019 to push the effort forward, with investments projected to hit $3 billion in FY22. https://www.defensenews.com/global/europe/2019/02/08/french-air-force-chief-france-and-germany-working-on-export-controls-for-future-fighter

Lockheed Martin Fields Safety Upgrade For F-35A Fleet
By Steve Trimble A crash-preventing upgrade for the Lockheed Martin F-35A is now being fielded after a nine-month test phase, program officials announced on July 24. The Automatic Ground Collision Avoidance System (Auto-GCAS) is being integrated on the U.S. Air Force variant first, but will also spread to the Navy and Marine Corps variants. Auto-GCAS, which is already fielded on the F-16, prevents crashes caused when a pilot partially or fully loses consciousness during aggressive flight maneuvers. The system can detect an imminent collision, take control and steer the aircraft to a safe heading. The Air Force credits Auto-GCAS for preventing eight F-16 crashes since 2014. “Auto-GCAS is a proven system that is long overdue,” said Lt. Gen. Eric Fick, F-35 program executive officer. https://aviationweek.com/defense/lockheed-martin-fields-safety-upgrade-f-35a-fleet?NL=AW-05&Issue=AW-05_20190725_AW-05_516&sfvc4enews=42&cl=article_2&utm_rid=CPEN1000015176279&utm_campaign=20501&utm_medium=email&elq2=71640d6c1c2a404d87e172f000eaa32d
