The Lockheed XF-90 was built in response to a United States Air Force requirement for a long-range penetration fighter and bomber escort. ... The XF-90 was the first USAF jet with an afterburner and the first Lockheed jet to fly supersonic, albeit in a dive. It also incorporated an unusual vertical stabilizer that could be moved fore and aft ...

2022年2月14日 · Overall, the aircraft shared some similarities to the P-80, but was a new design, designated the XF-90. The Lockheed XF-90 The airframe was designed before supersonic flight was completely understood, so the team working on the aircraft over-engineered its airframe to ensure it would survive such speeds.

The XF-90 was developed to meet a USAF requirement for a long-range penetration fighter. Two prototype aircraft were built. The first was powered by two Westinghouse J34 turbojets without afterburners, but these proved inadequate. The second aircraft was adapted for afterburning J34s and had better, but not great, performance.

The Republic XF-84H "Thunderscreech" is an American experimental turboprop aircraft derived from the F-84F Thunderstreak.Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the ...

The McDonnell XF-85 Goblin is an American prototype fighter aircraft conceived during World War II by McDonnell Aircraft.It was intended to deploy from the bomb bay of the Convair B-36 bomber as a parasite fighter.The XF-85's intended role was to defend bombers from hostile interceptor aircraft, a need demonstrated during World War II.McDonnell built two prototypes before the Air Force (USAF ...

While the Lockheed XF-90 appeared sleek, it wasn't. ... It was the first U.S. built, swept-wing jet to be equipped with afterburners and wingtip fuel tanks as standard equipment and have fully adjustable vertical and horizontal stabilizers. Fowler flaps and leading-edge slats improved airflow over the wings, making the F-90 one of the pioneers ...

2021年3月31日 · The XP-90 designation was eventually revised to become XF-90 in accordance to the shift from "Pursuit" (P) aircraft from the piston-powered days to "Fighter" (F) aircraft of the jet age. The early changes to the XF-90 product forced …

One of the hottest looking fighters ever to be built, but not go into production was the Lockheed XF-90. It was the first U.S. built, swept-wing jet to be equipped with afterburners and wingtip fuel tanks as standard equipment and have fully adjustable vertical and horizontal stabilizers.

2021年6月12日 · Lockheed built two prototypes, the XF-90 numbered 46-687, and an XF-90A #46-688 with an afterburning J34-WE-15 engine—the first U.S. fighter to be designed with the now-standard technology.

2023年5月19日 · While the XF-90 was not a successful design, it did have a big impact on the US Air Force for decades: In 1945, the U.S. Army Air Force issued a requirement for a “penetrating escort” jet that could accompany comparatively ponderous B-29 and B-50 strategic bombers all the way to targets over the Soviet Union.It wanted that jet to be capable of supersonic speeds, boast a combat radius of ...
