The Convair Model 58-9 was a planned American supersonic passenger jet developed by the Convair division of General Dynamics and intended to carry up to 52 passengers at Mach 2. It was derived from the Convair B-58 Hustler (Convair Model 4) bomber in 1961 , but was not pursued beyond the design phase.
development and construction
The Model 58-9 was Convair's proposal for the third step in a three-stage program to develop an SST based on the company's B-58 Hustler supersonic bomber. Derived from the proposed B-58C, an enlarged Mach 3 version of the Hustler, the Model 58-9 was supposed to be the next step, after an unmodified B-58 and a version of the bomber with a modified weapon pod that held five Passengers would have been modified. The version with the external weapon pod converted into a “passenger cabin” is an intermediate step towards the final version of the airliner. The development took place in the 1960s as part of a design competition in the SST program of the US government. This program was started by the US government to defend America's claim to be the technological leader against the Soviet Tupolev Tu-144 and the British / French Concorde . For the winning design, prototype funding was provided through state funds. Competitive designs represented the Boeing 2707 and the Lockheed L-2000 . While the designs by Lockheed and Boeing were further evaluated after the first phase of the competition, the NAC-60 , Douglas 2229 and the Convair model 58-9 were eliminated prematurely. In the end, the Boeing 2707 prevailed, but was not implemented for financial, political and technological reasons.
technology
The Model 58-9 was proposed in early 1961 and used the wing design of the B-58C, which was to be connected to an entirely new 45.75 m long fuselage. The cabin of the passenger aircraft could accommodate up to 52 passengers. The 58-9 model had a maximum takeoff mass of 86,000 kg and a range of 4,600 km (2,600 km) at a cruising speed of Mach 2.4. If the project had been approved, Convair predicted that the first prototype of the aircraft would fly within three years of the project's approval, with eighteen months of flight testing on four prototype aircraft after the aircraft's maiden flight. It was expected that the military air transport service would conduct simulated flights with the Model 58-9 during its development.
