Wide & Thin. Once they began to build experimental delta wings (Convair's XF-92 was the first to fly in 1948), airplane manufacturers discovered other advantages of what the designers call "delta configuration." The strain of high-speed flight tends to bend the airframe out of line. Without adding too much weight., the triangular structure can be built stiff enough to eliminate this danger. A relatively thin wing and its short fuselage-have room for fuel tanks, landing gear and auxiliary equipment...
Some designers believe that the wide delta wing is so stable in flight that it does not need the balancing action of a horizontal tail. All the necessary controls except the rudder, they say, can be built into its trailing edge. And a fast-acting electronic auto-pilot can be added to stop the bucking and pitching that have been known to flip a tailless plane into the beginning of a fatal somersault. But the GA-5, as an added measure of safety, carries a small delta tail high on its rakish...
Biggest drawback to delta wing planes is their performance at low speeds. To maintain lift during landing and take-off they must hold their noses awkwardly high, limiting the pilot's vision at times when he needs it most. But there are fighters already on the drawing board that will meet this difficulty with adjustable wings...
