A tailless aircraft means to keep the vertical tail and move the horizontal tail to the wing. 1943 Germany took the lead in manufacturing Me 163 tailless rocket interceptor during world war ii. This is the first tailless aircraft in aviation history. This kind of aircraft adopts a swept wing with short span, and the lift aileron that controls the lift action of the aircraft is installed at the trailing edge of the wing. A rocket engine is installed at the rear section of the fuselage, and a bicycle two-wheeled landing gear is installed below the fuselage. When the plane took off, the wheels were thrown away to reduce the weight and resistance. When landing, use the sled under the fuselage to slide on the runway. The short and thick fuselage contains 2 tons of fuel. So much fuel is only enough for the rocket engine to work 12 minutes. Although the working time was short, it could fly at a speed of 957 kilometers per hour, which was unmatched by any kind of aircraft at that time. Therefore, it is only suitable for the tactics of quick victory in a short time. Once you rush into the enemy fleet, attack quickly, whether you hit the target or not, and return to the base immediately. This tactic made the allied pilots do not know how to deal with it.
In the 1960s, the tailless delta wing aircraft was in its golden age, and many countries followed suit. Civil aircraft and bombers have also appeared in the form of tailless delta wings. For example, the high-speed passenger plane Concorde, Vulcan bomber, followed by depression. The main reason is that in several local wars in the 1960s, fighters still fought at low altitude and low speed, and countries no longer pursued high altitude and high speed when developing new aircraft, but needed good maneuverability.
Since then, the tailless delta wing is no longer so beautiful.
