Quiet Commercial Aircraft via Reduced Slat Deflection

Completed Technology Project

Project Introduction

Quiet Commercial Aircraft via Reduced Slat Deflection
We will conduct CFD for several slat deflections including the design configuration of 22 deg as well as lower slat deflections ranging from 6 – 16 deg. For optimum results, the computations will employ the LAVA solver on overset grids, a combination that has been proven effective for high-lift aerodynamic simulation. The computations will include numerous angles of attack to adequately identify the maximum lift which determines the minimum flight speed of the associate slat configuration. In collaboration with FAA, the variation in maximum lift with slat deflection will then be analyzed to determine the effect, if any, on air traffic control in the terminal area. More »
