Effects of Leading-Edge Figure on Aerodynamic Characteristics of 65° Delta Wing

EasyChair Preprint 7279

6 pagesDate: December 30, 2021

Abstract

Delta wing is used for hypersonic flying object. The specific feature of delta wing by comparison with
normal wing is that, the lift is created not only by potential flow but also by vortex flow. There are two
vortexes along the leading-edge. If the wing is in stability regime, the lift creating by the vortexes
helps increase total lift and stall angle of attack is reached to 40°. The creation of vortex is impacted
by the figure of leading-edge. The paper presents the result of dependence of aerodynamic parameters
and vortexes on the figures of leading-edge by using Ansys software. As the result, the paper brings
some evaluation and optimal choice for the figure of leading-edge in the stage of design the wing.

Keyphrases: ANSYS Fluent, Delta wing, Longitudinal vortex
