Aircraft Engine and Propeller Sizing

Welcome to Part 10, the final installment in the Fundamentals of Aircraft Design series. In Part 9 we completed a preliminary drag estimation of a new light sport aircraft design. In this tutorial we build on from the drag estimation, and specify an engine and propeller combination in order to determine the variation in thrust with airspeed. By superimposing this thrust curve onto the drag graph, we can calculate the aircraft’s theoretical maximum speed, or speed at various engine power settings. Let’s get started!
