TL;DR

The study discusses wave interference effects for mirror‑symmetric and antisymmetric wing/body arrangements and proposes their application to moderate‑supersonic transport aircraft. The authors review prior work on oblique elliptic wing combinations and note that single continuous wing panels adapt readily to changing obliquity and flight speed. The study finds that antisymmetric arrangements yield significantly lower wave drag than mirror‑symmetric ones, and that single continuous wing panels adapt readily to changing obliquity and flight speed.

Abstract

The wave interference effects for bodies or wings in a mirror-symmetric arrangement, and in an antisymmetric arrangement are discussed. It is shown that while in the case of a mirror-symmetric arrangement large adverse interference effects can be observed, antisymmetric arrangements provide comparatively much smaller wave drags. The single continuous wing panels also adapt themselves more readily to varying angles of obliquity, and hence, to varying flight speeds. The single continuous wing panels also adapt themselves more readily to varying angles of obliquity, and hence, to varying flight speeds. A detailed review is presented of the previous work on the aerodynamic properties and flight stability of oblique elliptic wing combinations. A possible mode of application of these combinations to transport aircraft operating at moderate supersonic speeds is suggested.
