Definition of Initial Landing and Takeoff Reference Configurations for the High Lift Common Research Model (CRM-HL)

Abstract

The High Lift version of the Common Research Model (CRM-HL) is a geometry set developed to enable high lift configurations representative of those found on modern commercial airliners to be made available in the public domain. An effort is underway to create an ecosystem around this geometry set that will enable multiple users to collaborate on key common configurations that produce flow physics scenarios of shared interest. Such configurations will be referred to as reference configurations. Anticipated collaborative topics include CFD tool improvement and validation, technology development, and wind tunnel data acquisition methodology development. This paper will define two such reference configurations with the goal of establishing common geometry for these future efforts. It will include a discussion of the objectives for these configurations as well as the rationale behind their selection. It will also provide detailed configuration descriptions, broken down into the individual geometry elements.
