The delta wing was developed by Dr. Alexander Lippisch into flying aircraft kerbal space program mod

The Soviet Union became a strong threat to the West after WWII and the development of the atomic weapon removed the natural protection of the oceans and long distances, at least for the United States. Faced with these facts, the U. S. made it a priority to develop all weather fighter interceptors for the primary task of defending U.S. soil from Soviet strategic bombers. Convair signed a contract with the U.S. Army Air Forces on 25 June 1945 for the continued development of a delta wing interceptor.
The delta wing was developed by Dr. Alexander Lippisch into flying aircraft kerbal space program mods in the early 1930s and refined further during WWII. Overall, this type of wing was easy to manufacture and has a large internal volume which equipment and fuel could occupy. In addition, flying controls could be arranged to allow for the elimination of horizontal flying surfaces. Postwar, Convair spent a lot of time and effort kerbal space program mods developing the delta wing planform and their XF-92 design provided real world data from its flight test program. That data was a milestone that led to the development of the F-102, F-106 and B-58.
What became the F-102A Delta Dagger started out as Secret Project MX-1554 , also known as Dragon Fly . The program was also called 1954 Interceptor as the idea was to have the new fighter in service in 1954. Both radar/fire control system and guided missiles developments ran in parallel with the fighter s development as well. Overall, this was one of the first weapons system programs. Convair s proposal used the delta wing planform and had internal storage in the fuselage kerbal space program mods for the missiles. The project requirements required kerbal space program mods a top speed of Mach 1 but in 1952, wind tunnel testing determined that the proposed design could not reach that speed due to drag. The reason was simple the cross section area of the airframe increases through the area where the wing and fuselage add up and that added area creates a significant kerbal space program mods drag increase at higher speeds. NACA s Richard Whitcomb developed the area rule concept a smooth transition of the overall cross section of the aircraft from nose to tail which resulted in a reduction in the fuselage cross section to account for the wing cross section and creating what is generally called a wasp waist or Coke Bottle look. Whitcomb s development was directly applied kerbal space program mods to the F-102 to solve the unexpectedly higher drag encountered kerbal space program mods with the design. The area rule concept kerbal space program mods is still in use today. kerbal space program mods
Convair YF-102A at Edwards Air Force base, California, on taxi run to begin its maiden flight. November 1953. In most aspect this features all of the construction elements of the future manufactured machines.
The first development kerbal space program mods F-102s were too far along in construction to incorporate area rule and flew as originally designed. The YF-102 (52-7994) made its maiden flight on 24 October 1953 at Edwards AFB with Convair test pilot Dick Johnson at the controls. 52-7994 did not last long on 1 November 1953, an engine failure on take off during a test flight led to a crash landing and the aircraft was written off. The follow on YF-102 (52-7995) first flew 11 January 1954.
The YF-102A prototypes/development aircraft (starting with 53-1787) were the first airframes to incorporate the area rule concept and its impact was immediately felt when on the second flight of 53-1787 on 21 December 1954, it reached Mach 1. The revised kerbal space program mods design reached Mach 1.22 and an altitude of 53,000 feet proof of the worth of Whitcomb s aera rule concept.
Area rule is one of the greatest invention which helps aircrafts to pass into the supoersonic world. Note on this image how the fuselage become narrow in the middle. This particular machine still does not have splitter plate on the air intakes.
The success of the YF-102A to meet the stated requirements led to the U.S. Air Force proceeding with production of the F-102A Delta Dagger. Early production aircraft had a smaller vertical fin which in service was found to be inadequate for roll/coupling issues. This led to a redesign which increased the vertical height (and area) of the fin and was introduced on the production line starting with Block 25 aircraft. All earlier F-102As were retrofitted with the larger vertical fin.
Many of the early manufacturer block F-102As did not reach operational units but were used for various test programs. The official name given to the F-102A was Delta Dagger but in actual service pilots and ground crews universally called it the Duece. The 327th Fighter Interceptor Squadron at George Air Force Base in California was the first to receive the F-102A in April, 1956.
