Guest Lecture: Inlet Design

Today, we learn the basics of aircraft inlet design.

This November, I was asked to provide a substitute lecture to a senior level propulsion class (AEM 408). For this lecture, I attempted to provide the basics of inlet design by discussing the relevant physics and constraints.

Inlet fan face total pressure was introduced as a way to quantify the performance of an inlet and to diagnose common issues.

The concept of boundary layer growth with the inlet’s adverse pressure gradient was reinforced from an earlier Aerodynamics I course.

The lecture notes are available here: https://charles-oneill.com/docs/InletTalkAEM408.pdf

Thanks and best wishes to the UA Aero 2018 Seniors.
