这 康维尔XF-92 （最初被命名为XP-92）是美国早期的三角翼飞机。最初被设想为点防御拦截器，该设计后来纯粹用于实验目的。然而，它导致康维尔在许多设计中使用三角翼，包括F-102三角洲匕首，F-106三角洲飞镖，B-58 Hustler，美国海军的F2Y海上飞镖以及VTOL FY Pogo。

General Characteristics and Role
The Convair XF-92A Dart was a single-seat, experimental jet aircraft developed for the U.S. Air Force (USAF) in the late 1940s. Although initially conceived as a prototype interceptor (designations XF-92/YF-92), its true significance lies in its role as a pure research vehicle. The XF-92A was the first American jet aircraft to fly with a delta wing configuration. Based on aerodynamic research by German engineer Alexander Lippisch, this radical wing shape was crucial to Convair’s supersonic aircraft development. The XF-92A successfully proved the feasibility of the delta wing design for high-speed flight, directly leading to the development of the F-102 Delta Dagger and the B-58 Hustler.

Powerplant and Delta Features
- Engine: Initially a General Electric J33-A-21 turbojet, later upgraded to a Allison J33-A-29 turbojet with afterburner.
- Thrust (Max): Approx. 3,400 lbf (15 kN) (original J33); 8,300 lbf (37 kN) (upgraded J33-A-29 with afterburner).
- Aerodynamics: The delta wing featured a 60-degree sweep along the leading edge. The absence of a conventional horizontal stabilizer meant the single control surfaces (elevons) handled both pitch and roll control.
- Maximum Speed: The upgraded version was capable of speeds approaching the speed of sound, with Mach 0.95 being achieved during flight testing.
- Key Contribution: The XF-92A was vital in studying the flight characteristics of the delta wing, particularly issues related to high angle-of-attack handling and high-speed stability.
Program Legacy and Impact
- Pilot Feedback: Test pilots, including Chuck Yeager, praised the aircraft’s high-speed handling but noted poor low-speed maneuverability, particularly during landing approach, which required high pitch angles.
- Influence: The XF-92A is considered the direct predecessor to all of Convair’s supersonic delta wing interceptors and bombers, setting the path for aircraft such as the F-102 Delta Dagger, the F-106 Delta Dart, and the B-58 Hustler strategic bomber.
- Retirement: The sole prototype flew over 250 times and was retired in 1953 after successfully completing its primary research objectives.
- Preservation: The single XF-92A built (AF Ser. No. 46-682) is now on permanent display at the National Museum of the United States Air Force in Dayton, Ohio.
