Application of the ASP3D Computer Program to Unsteady Aerodynamic and Aeroelastic Analyses [PDF]
A new computer program has been developed called ASP3D (Advanced Small Perturbation - 3D), which solves the small perturbation potential flow equation in an advanced form including mass-consistent surface and trailing wake boundary conditions, and ...

Feasibility study of the transonic biplane concept for transport aircraft application [PDF]
Investigations were conducted to evaluate the feasibility of a transonic biplane consisting of a forward-mounted swept-back lower wing, a rear-mounted swept-forward upper wing, and a vertical fin connecting the wings at their tips.
