Mach 3 performance in the 1950s was difficult to achieve. Jet engines compress incoming air, then mix it with fuel and ignite the mixture. The resulting expansion of gases produces thrust. The compressors generally can ingest air only at subsonic speeds.

Jan 16, 2020 · The most unique feature of the XF-103 was the dual-cycle propulsion system which could act as a traditional turbojet as well as a ramjet. The combination of the Wright Aeronautical Corporation XJ67 engine and XRJ55 afterburner unit meant the turbojet could be shut down for speeds above Mach 3 making the XF-103 a pure ramjet.

Dec 28, 2019 · Key point: Had the U.S. Air Force actually fielded an F-103, it would probably have been a supersonic waste. Before the advent of ICBMs in the 1950s, the horsemen of the nuclear apocalypse...

Three of the Century Series aircraft—F-101, F-102, and F-106—were armed with nuclear air-to-air missiles.

Sep 23, 2016 · Of the three designs, the XF-103 was the most advanced. Republic proposed an aircraft that could fly 2,600 miles per hour—faster than three times the speed of sound—to an altitude of 80,000...

The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners.

The XF-103 was developed as a high-speed high-altitude aircraft specifically designed to intercept incoming enemy bombers. The XF-103 was proposed in the same contract competition that resulted in the Convair F-102--Project MX-1554 Interceptor Fighter Airplane.

Jul 21, 2021 · Of the three designs, the XF-103 was the most advanced. Republic proposed an aircraft that could fly 2,600 miles per hour—faster than three times the speed of sound—to an altitude of 80,000...

In the 1950s, as the threat from Soviet jet bombers (and associated nuclear transport capabilities) increased, the United States Air Force (USAF) sought solutions to the problem at hand, resulting in a dizzying array of concepts, The development and production of …

capable of flying at Mach 3 in just 10 years. In 1949 the Air Force issued a Request for Proposals (RFP) for an advanced interceptor capable of defending against the new Soviet intercontinental...
