TWIST OF PARAGLIDING ARCHED WINGS

V.E. Aleksandrov, P.I. Ivanov

The subject which is under consideration is connected with the necessity of the development of the methods of aerodynamic and aircraft performance characteristics of paraglider’s wings of high-fineness ratio increasing. Some major conceptions and definitions related to the twist of paragliding arched wings have been introduced. The options of airfoil combinations whilst carrying-out of a programme of model tests have been proposed in order to analyse the paragliding arched wings texting. The guidelines of experimental research for the making up, in perspective, the catalogue of paragliding wings with the twist characteristics have been proposed. The problems of optimization related to the balanced set of flight condition of the wing. We also consider some specific features and problematic issues associated with a twist of paragliding arched wings.

Key words: paraglider, geometric and aerodynamic wing twist, design, optimization.
