Abstract

This document presents the results of analysis of the tests with ALVAST and CRUF at different power settings at the Mach numbers 0.18, 0.27 and 0.34. The pressure distribution at the wing sections is shown at different angles of attack and thrust conditions. In addition the effects of thrust and Mach number on wing pressure distribution, local lift, overall lift and drag are shown. Also investigated are the effects of thrust and Mach number on nacelle, pylon and fuselage, with the most attention being payed to the influence on the nacelle. Finally a comparison of TPS and CRUF measurements shows directly the advantages or disadvantages of CRUF compared with conventional propulsions (TPS) and Clean configurations. It is shown for wing pressure distribution,local lift at wing sections, overall lift and drag.
