Abstract: An aircraft wing (104) is disclosed herein having a fixed-location trip device (108) placed along the span of the wing to transition airflow from laminar flow (302) to turbulent flow (306) so that potential load increases are limited and flight performance uncertainties associated with laminar flow wings are reduced. Wings designed for extended laminar flow offer the potential to significantly reduce airplane drag and fuel consumption. A collateral impact of a laminar flow wing is the generation of elevated wing loads at critical load conditions. This impact is mitigated by controlling the downstream limit of transition at these critical load conditions.
