Abstract

Recently NAL has designed a natural laminar flow airfoil NAL--MSNLF-136 for use on a-genergl aviation aircraft for the design copditions M - 0.6, R - 10 x 10 and C -0.4. In order to validate this airfoil in the NA l' x 'I' tunnh , performance calculations have been carried out with 5% and 10% boundary, layer trippings. It is generally seen that while the lift co-efficients decrease the drag co-efficients increase relative to the natural flow case
