The North American NAC-60 was the first American supersonic transport (SST) project. The development took place in the 1960s as part of a government-funded design competition to build an American SST [1] as the joint Anglo-French Concorde and the short-serviced Soviet Tupolev Tu-144 were underway. The design, however, due to being slower and smaller than the expectations of the American SST Race, was rejected in favor of the Lockheed and Boeing designs, allowing them to get further study.

Design

In some respects, the NAC-60 was a scaled-up variant of North American's bomber prototype, the B-70 Valkyrie. As with the B-70, the design of the NAC-60 did not include horizontal stabilizers at the tail structure, but did include a set of canards at the nose, to improve directional stability at lower speeds. (The Concorde with which it was intended to compete had a wing designed for both subsonic and supersonic flight and, as a result, did not need canards.) And instead of twin rudders like on the B-70, there was just one rudder. This SST also had a less tapered fuselage and a more compound wing than the B-70's.

Concorde British-French supersonic airliner

The Aérospatiale/BAC Concorde is a Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation and the British Aircraft Corporation (BAC). Studies started in 1954, and France and the UK signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million . Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969. The market was predicted for 350 aircraft, and it received up to 100 options from many major airlines. On 9 October 1975, it received its French Certificate of Airworthiness, and from the UK CAA on 5 December.

Tupolev Tu-144 Soviet supersonic passenger airliner

The Tupolev Tu-144 is a Soviet supersonic passenger airliner designed by Tupolev in operation from 1968 to 1999.

Boeing 2707 Proposed American supersonic passenger airliner

The Boeing 2707 was an American supersonic passenger airliner project during the 1960s. After winning a competition for a government-funded contract to build an American supersonic airliner, Boeing began development at its facilities in Seattle, Washington. The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise speeds of approximately Mach 3. It was intended to be much larger and faster than preceding SST designs such as Concorde.

Supersonic transport Type of commercial airliner (SST)

A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde's last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service. Several companies have each proposed a supersonic business jet, which may bring supersonic transport back again.

Lockheed L-2000 Proposed US supersonic airliner design

The Lockheed L-2000 was Lockheed Corporation's entry in a government-funded competition to build the United States' first supersonic airliner in the 1960s. The L-2000 lost the contract to the Boeing 2707, but that competing design was ultimately canceled for political, environmental and economic reasons.

Bristol Type 223 Early British design for a supersonic transport

The Bristol Type 223 was an early design for a supersonic transport. In the late 1950s and early 1960s the Bristol Aeroplane Company studied a number of models as part of a large British inter-company effort funded by the government. These models eventually culminated in the Type 223, a transatlantic transport for about 100 passengers at a speed around Mach 2. At about the same time Sud Aviation in France was developing the similar Super-Caravelle design, and in November 1962 the efforts were merged to create the Concorde project.

North American XF-108 Rapier Canceled interceptor aircraft project

The North American XF-108 Rapier was a proposed long-range, high-speed interceptor aircraft designed by North American Aviation intended to defend the United States from supersonic Soviet strategic bombers. The aircraft would have cruised at speeds around Mach 3 with an unrefueled combat radius over 1,000 nautical miles, and was equipped with radar and missiles offering engagement ranges up to 100 miles (160 km) against bomber-sized targets.

Tupolev Tu-244 1979–1993 proposed supersonic passenger airliner

The Tupolev Tu-244 was a proposed supersonic transport (SST) aircraft, developed from the Tu-144. It implemented novel features such as cryogenic fuel to enable flight distances of up to 10,000 km (6,200 mi) and would have carried up to 300 passengers. The project was cancelled in 1993.

Gyroflug Speed Canard

The Gyroflug SC 01 Speed Canard is an unconventional sports plane produced in Germany in the 1980s and 1990s. Inspired by the Rutan VariEze, the Speed Canard was an all-new design created without input from Rutan. Like the VariEze, the Speed Canard is a canard-configured mid-wing monoplane with wingtip fins that incorporate rudders. The two-seat tandem cockpit and canopy design were derived from Grob Twin Astir sailplane, and the nosewheel of the tricycle undercarriage is retractable. Construction throughout is of composite materials, and when the design attained German certification in 1983, it became the first composite canard design to achieve certification anywhere in the world. An interesting feature of the control system is that the twin rudders operate independently, allowing both rudders to be deflected outwards simultaneously, cancelling each other's yaw, but acting as airbrakes.

Douglas Aircraft Company's Model 2229 was a proposed supersonic transport (SST) originally started as a private study. The design progressed as far as making mock-ups of the cockpit area and wind-tunnel models of the overall layout. After studying the design, Douglas concluded that the SST would not work economically, and declined to enter the Model 2229 in the National Supersonic Transport (NST) program in 1963.
