At sae.org - GE, Lockheed Martin commit to Aerion's supersonic bizjet - 21-Dec-2017
“Conditions are ripe for a supersonic renaissance,” said Brian Barents, Executive Chairman, Aerion. “We believe that speed is the next frontier in civil aviation, and we will begin that journey with a supersonic business jet capable of reaching demanding city pairs frequently traveled by the business community.”
Barents made his comments during an announcement in mid-December that his company and Lockheed Martin, along with GE, are participating in a Memorandum of Understanding (MOU) for the engineering and development necessary to bring Aerion’s AS2 supersonic business jet to fruition, runways, and airspace.
Out of those three companies, Aerion is the newest player in this market, having announced its Aerion program in 2003.
“We recognized several critical factors essential for our success. One of those was teaming with an established, reputable airframe manufacturer that would help us to design, certify, build, and support the airplane going forward,” said Barents. “We've been engaged with Lockheed Martin for the past year, including months of vetting the technology and the AS2 conceptual design.”

“For us, the supersonic era started with our J-79 engine that was introduced on the Lockheed F-104 Starfighter in the late 1950's,” said Brad Mottier, Vice President, General Manager of GE Aviation and Integrated Systems. In May, GE officially announced it was working with Aerion on an engine development study for the AS2.
Just in the civilian space, GE’s work on other engine programs include the Leap, Passport, Advanced Turboprop for the Cessna Denali, and the GE9X for the 777X. “Combined, these engines introduce nearly 500 new technologies to the aviation marketplace. The toolbox of engine technologies we are introducing is mounting at its own supersonic speed,” said Mottier. “Ceramic matrix composites, additive manufacturing, titanium aluminides, along with digital services and artificial intelligence, are maturing technologies and will enable new solutions to some of the more complex challenges ahead.”
Mottier admits that developing an engine for a supersonic business jet is no easy task, “otherwise someone would have done it before.” And while it will take “a tremendous amount of collaboration between the airframer and engine maker to pull off this integration, this will really be a marriage of technologies.”
Aerion advanced the aerodynamics and structural design of the AS2 through a previous engineering collaboration agreement with Airbus. The two companies developed a preliminary design of wing and airframe structures, systems layout, and preliminary concepts for a fly-by-wire flight control system.
The 12-passenger AS2 is expected to fly at a maximum speed of Mach 1.4 over water, and, where permitted by regulation, at speeds approaching Mach 1.2 without a sonic boom reaching the ground.
