Conceptual Design of Swept Wing Root Aerofoils

For modern transonic transport aeroplanes, it is important to produce low drag at high cruise speeds. The root effect, caused by effects of symmetry on swept wings, decreases the performance of these aeroplanes. During aeroplane design, root modifications are applied to counteract this decrease in performance. Most conceptual aeroplane design...

Comparison of boundary layer calculations for the root section of a wing

At the workshop nine participants presented the results of their calculations for a practical test case. The test case deals with the 3D turbulent boundary layer development, including separation, on the root section of a swept wing. The employed calculation methods comprise 3D integral methods as well as field methods. A short description of...

MINITWIST: A shortened version of TWIST (Transport WIng STandard Load computer programme)

The Transport Wing Standard programme (TWIST) published in March 1973 is considered to be representative for the load history of the wing root of transport aircraft. A description of the shortened version of this load programme called MINITWIST is given in the present report. In all cases where testing time is a prohibitive factor to use TWIST,...
