Challenge Problems
Push your limits with advanced challenges
A vehicle is designed to achieve high speeds while minimizing drag. Describe how an understanding of boundary layers can impact its design approach.
💡 Hint: Think of aerodynamic shapes and how they interact with flowing air.
Given an aircraft wing designed for a Reynolds number of 200,000, calculate the expected boundary layer thickness if it affects drag on takeoff. Consider airflow speed and design features.
💡 Hint: Recalling the equations for boundary layer thickness in relation to Reynolds number will guide your calculations.
