Abstract

A series of wind tunnel experiment models with various Diamond Back wings were designed with a modularized method, and 6-component measuring experiments were conducted to study the aerodynamic characteristics of the Diamond Back wings under the conditions of Ma=0.4-0.8, α=-2°-12° and δ_z=-5°. The experimental results indicate that the Diamond Back wing is suitable for gliding extended range of unpowered guided bomb unit based on high lifting force, C_L/C_D ≥ 5 and high gliding extended range ability; the local slope of C_L-α curve reduces rapidly under the condition of α > 6°; the attack angle of gliding flight should be selected according to maximum C_L/C_D.
