In the 1950s, she developed a simultaneous treatment of all the features of a wing ( thickness, twist, sweepback, camber ) to predict the air pressure distribution over it.
42.
Pressure distributions can also be conveniently measured by the use of pressure-sensitive pressure belts, a recent development in which multiple ultra-miniaturized pressure sensor modules are integrated into a flexible strip.
43.
The problem was remedied by adding a " dive flap " beneath the wing which altered the center of pressure distribution so that the wing would not lose its lift.
44.
With an initial estimate of the pressure distribution on the wing, the structural designers can start designing the load-bearing parts of the wings, fin and tailplane and other lifting surfaces.
45.
This leads to a distinctive " double boom " from a supersonic aircraft . When the aircraft is maneuvering, the pressure distribution changes into different forms, with a characteristic U-wave shape.
46.
The pressure distributions across the test model have historically been measured by drilling many small holes along the airflow path, and using multi-tube manometers to measure the pressure at each hole.
47.
The linearized theory predicts the general character of the airfoil pressure distribution and how it is influenced by airfoil shape and angle of attack, but is not accurate enough for design work.
48.
Depending on the seal type these two angles are varied to create a pressure distribution at the seal contact point which has a steeper slope on the oil side of the seal.
49.
If an elastic sphere is pressed onto an elastic plane of the same material then both bodies deform, a circular contact area comes into being, and a ( Hertzian ) normal pressure distribution arises.
50.
On his own initiative he developed a method to predict the pressure distribution over the wing using mathematical formulae to describe the shape of the wing section combined with a solution of air compressibility equations.
