Results from comprehensive wind tunnel tests will provide performance and aerodynamic characteristics
and structural load data, further finalizing the aircraft design.
The most visible new features of the A330neo wings are the specially developed curved wingtip Sharklets - which draw on A350 XWB technology, extending the wingspan to 64 metres, providing state-of-the art aerodynamic characteristics
Hypersonic vehicles have to maintain their shape to get the right aerodynamic characteristics
, Braun explained, which is harder than it sounds when the aircraft's surface is heated to thousands of degrees Fahrenheit due to air friction.
The sidebar correctly notes that an airplane's unstable aerodynamic characteristics
can contribute to fatigue.
The new large-scale wind tunnel will be equipped with a moving belt function that can simulate complex real-life driving situations and will be used to improve aerodynamic characteristics
, environmental performance and noise levels.
These specifications were not affected by the upgrade, but all the aerodynamic characteristics
, like the boundary layer profile, were checked again afterwards.
By changing the voltage, the shape of the electroactive membrane and therefore aerodynamic characteristics
can be altered during flight.
1 used an airfoil called the Goettingen 298, with the Goettingen test data published in (NACA, AERODYNAMIC CHARACTERISTICS
OF AEROFOILS-11, NACA TR-124 1923) and is shown in Figure 17.
Brown begins with a chapter on "stringent design requirements for naval aircraft" including comments on needs for adequate undercarriage structure, landing visibility, aircraft attitude and aerodynamic characteristics
, arresting gear, and requirements for multi-engine designs.
Differences in aerodynamic characteristics
and trends between these two configurations are presented.
It was stated that a "UFOB" was "any airborne object which by performance, aerodynamic characteristics
, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object.
Their topics include the aerodynamic design of wind turbine rotors, aerodynamic characteristics
of the blade airfoils, effects of resin and reinforcement variations on fatigue resistance, the micromechanical modeling of materials surface protection and coatings, and wind turbine blade structural performance testing.
