The process is repeated. This takes place within 2 miles (3.2 km), or 4 minutes away from the tornado itself. [18] The team had 24 2 metres (6.6 ft) high portable Sticknets, which can be set up at various locations around tornado storm cells to measure wind fields, provide atmospheric readings, and record acoustically the hail and precipitation.
In testing by Boeing and NASA, they reduce drag by as much as 5.5%, compared to 3.5% to 4.5% for conventional winglets. [1] While an increase in span would be more effective than a same-length winglet, its bending moment is greater. A 3 ft (91 cm) winglet gives the performance gain of a 2 ft (61 cm) span increase but has the bending force of a ...
The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing , of an aircraft as an infinitely thin sheet of discrete vortices to compute lift and induced drag .
