TWIST OF PARAGLIDING ARCHED
WINGS OF BIG ASPECT RATION AND PROBLEMS OF OPTIMIZATION IN COMPUTER ANALYTIC
DESIGN
P.I. Ivanov
The problem is connected with the development of
methods of enhancement of aerodynamic and flying tactical characteristics of paragliding
arched wings of big aspect ration. In this work some basic concepts and
definitions were introduced, they are connected with the computer design of the
arched wing with geometric and aerodynamic twists. The aim of twist was
revealed, the problems of optimization that are connected with the necessity of elimination of a
number of contradictions between
parameters and characteristics were analyzed. The examples of specific cases of
contradictions between the characteristics under the condition of
construction’s geometric parameters changing were given.
Key
words: paraglider,
geometric and aerodynamic wing twist, computer analytic design, optimization.
