The American company Aerion has announced the intention to hold the first transatlantic flight of their advanced supersonic passenger aircraft AS2 23 Oct 2023.
As written by Aviation Week, the flight was planned to coincide with the 20th anniversary of the last flight of the French supersonic passenger plane Concorde.
Civil supersonic aircraft does not exist today. In the 1970-ies was commissioned by the Russian Tu-144 and the French Concorde. First in passenger transport has been used less than a year. The last flight of the Concorde took place in October 2003 on the route new York- London. Both aircraft were written off due to the very high cost tickets on flights.
According to the approved plan Aerion, conceptual design of the new aircraft is scheduled for completion by mid-2020, and the protection of the technical project to be held in early 2022. After the defense has already assembled the plane will make its first flight within a year and a half.
The developers expect that certification of the new aircraft will be completed by the end of 2025, and 2026 of new supersonic aircraft will start performing regular flights. For the first year of serial production of Aerion plans to build 12 AS2, 2027 needs to be compiled 23 aircraft, but for 2028-th — 36. In the future, each year the company will release 36 AS2 2035.
Development of AS2 is 2014. According to preliminary calculations, the length of the plane will be of 51.8 meters height — 6.7 meters, and the wingspan is 18.6 meters. Maximum takeoff weight of supersonic aircraft will amount to 54.8 tons. AS2 will be equipped with three engines, thrust each of which will be about 69 kN. The aircraft will carry up to 12 passengers.
AS2 will fly over water at a cruising speed of 1.4 Mach number, decelerate to 1.2 over land. Some less flight speed over land coupled with the special aerodynamic airframe will allow, as I expect the developers to almost completely avoid the formation of shock waves.
The flight range of the aircraft at the speed of 1.4 Mach number will be 7.8 thousand kilometers and 10 thousand kilometers at the speed of 0.95 Mach number. Current international rules prohibit the flight of supersonic aircraft over populated land areas.
Earlier it became known that the demonstrator perspective supersonic passenger aircraft, developed by the American company Lockheed Martin for the project QueSST, received the official designation index X-59. The designation was assigned to aircraft in accordance with the tradition that began in 1947, when testing of the rocket plane X-1. The construction of a new supersonic aircraft has already begun.
