Küchemann was born in Göttingen where he studied at its University of Göttingen, home of the largest German institute of aerodynamics.He was originally going to move on to pure physics research under Max Born, a friend of his father's, but lost this chance when Born and several other Jewish members of the University staff were expelled from the country by the Nazi regime.
Max Taitz (1904–1980) – scientist in aerodynamics and flight testing of aircraft, one of the founders of Gromov Flight Research Institute; Kurt Tank (1898–1983) – designer of aircraft in Germany, Argentina, and India; Clarence Gilbert Taylor (1898–1988) – designer of the Piper Cub; Moulton Taylor (1912–1965) – experimental ...
In aerodynamics, compression lift refers to the increased pressure under an aircraft that uses shock waves generated by its own supersonic flight to generate lift. This can lead to dramatic improvements in lift for supersonic / hypersonic aircraft.
An elliptical planform is the most efficient aerodynamic shape for an untwisted wing, leading to the lowest amount of induced drag. The semi-elliptical planform was skewed so that the centre of pressure, which occurs near the quarter- chord position at all but the highest speeds, was close to the main spar, preventing the wings from twisting.
An Aerobie ring. An Aerobie is a flying ring used in a manner similar to a chakram or flying disc (Frisbee), for recreational catches between two or more individuals. Its ring shape of only about 3 mm (0.12 in) thickness [1] makes the Aerobie lighter and more stable in flight than a disc. [2]
Also, an aerodynamic force is imposed by the relative vertical positions of the fuselage and the wings, creating a roll-in leverage if the fuselage is above the wings, as in a low wing configuration; or roll-out if below, as in a high-wing configuration. A propeller rotating under power will influence the airflow passing it.
The first XB-70 carried out its maiden flight in September 1964 and many more test flights followed. [71] The data from the XB-70 test flights and aerospace materials development were used in the later B-1 bomber program, the American supersonic transport (SST) program, and via espionage, the Soviet Union's Tupolev Tu-144 SST program.

Normally the boundary layer is quite thin compared to the streamline of airflow over the wing, and can be considered separately from other aerodynamic effects. However, as the speed increases and the shock wave increasingly approaches the sides of the craft, there comes a point where the two start to interact and the flowfield becomes very complex.
