Aerion Corp. has opened its order book and set a price for its AS2 supersonic business jet: $120 million in 2015 dollars. The first 50 customers will receive preferential pricing and other benefits available only during the first round of orders. “This is another step forward for Aerion,” said chairman Robert Bass. “We are offering a select group of forward thinking business aviation users the opportunity to fly faster and to make history with us as we reintroduce commercial supersonic flight.” The company will be having discussions with travelers who place a high price on their time, said Ernest (Ernie) Edwards. Edwards, the former president of Embraer Executive Jets who joined Aerion as SVP and chief commercial officer. They will be able to save three hours flying time between Paris and Washington D.C. and more than six hours between San Francisco and Singapore
With its new three engine configuration, the AS2 is able to take greater advantage of the unique Aerion "unswept" SNLF (Supersonic Natural Laminar Flow) wing design. This sees the wing feature upper and lower surfaces that are slightly curved, ensuring a smooth flow of air across them that continues to travel in relatively undisturbed layers. Aerion claims this results in a 90 percent reduction in drag over more conventional swept or delta wing designs and helps reduce total airframe drag by as much as 20 percent. As a result, it is expected that the AS2 will not only be fast, but super-efficient as well.
Capable of a maximum speed of Mach 1.6, the AS2 has been designed to travel at two optimal cruising speeds where range and efficiency are at their best: Mach 0.95 where supersonic flight is prohibited, and at Mach 1.4 where the SNLF wing characteristics will be at their most efficient. Dimension-wise, the fuselage is 160 ft (48 m) long and maximum take-off weight is expected to be around 115,000 lb (52,000 kg). With these figures, the minimum projected range is predicted to be approximately 4,750 nautical miles (8,800 km), though the company is hoping to achieve an ultimate range of around 5,000 nm (9,260 km).
With a 30-ft (9.1-m) cabin in a two-lounge configuration, cabin dimensions widen from entryway to the rear seating area where height is about 6.2 ft (1.9 m) and cabin width around 7.2 ft (2.2 m). When fully fueled, it is expected that the AS2 will require a take-off length of roughly 7,500 ft (2,286 m), though this is expected to drop to only 5,000-6,000 ft (1,500-1,800 m) at take-off weights below 100,000 lb (45,000 kg), while still maintaining trans-Atlantic and transcontinental US capability. This should allow the aircraft to operate from medium-sized aviation hubs as and when necessary. According to the company, the new AS2 configuration draws on worldwide operator input from a market study conducted by Aerion in the first quarter of 2014 to assess demand for a supersonic business jet. "The message from many of today’s long-range business jet operators is very clear," says Aerion CEO Doug Nichols. "They want a supersonic jet sooner rather than later; a cabin comparable in comfort to today’s long-range jets; a range of 5,000 nm or better; and they are willing to pay more than US$100 million for such an aircraft. That is the supersonic jet we are working to deliver.”
Whilst the AS2 is still in the design stage, Aerion does have plans to form an industrial collaboration with aerospace firms capable of supplying engines and airframe structures before the end of 2014. The release date for entry into service, provided certification is achieved, is 2021. Given that there are also a number of other supersonic business jet concepts on drawing boards around the globe – such as the Spike S-512 and the Hypermach SonicStar – which are also aiming at a takeoff date somewhere in the same time-frame as Aerion’s offering, the period up to 2021 promises to be a very interesting time for aviation watchers. And, if all comes to fruition, it's also an exciting time for those of us who look forward to the ushering in of a new age of supersonic travel.
Aerion is planning to carry out low-speed wind tunnel tests in September at the University of Washington. The company is expanding its engineering organization and has deepened its ties with the Airbus Group as they participate in a joint definition phase refining the AS2 design. In March it moved into new and expanded offices in Reno, Nevada to accommodate its growing staff and provide space for the two companies’ engineers to work together. Aerion has made “substantial progress in defining the AS2 from the inside out,” CEO Doug Nichols said.
