Learning outcomes

Starting from the main results of aircraft subsonic aerodynamics, fundamental issues of jet and propeller aircraft performances are carried out within the classical flight condition (steady level flight, climb, gliding, and steady turn). Longitudinal, lateral and directional static stability and longitudinal controllability are also addressed.

Course contents

Introductory topics

Course introduction. Aircraft geometry. Earth atmosphere ISA model.

Equations of motion and subsonic aerodynamics review

Reference frames and 3 dof point-mass model. Drag polar and aerodynamic efficiency.

Aircraft Performances

Gliding performances. Steady level flight aircraft performances: range and endurance: jet and propeller aircraft. Cruise performance of electrical aircraft. Constant power discharge model for Li-Po batteries. Climb and descent performances. Steady turn. Take-off and landing. Aircraft limitations: load factor and flight envelope. High-lift devices.

Aircraft stability, controllability, and manoeuvrability

Introduction to aircraft stability. Longitudinal static stability: neutral point. Directional and lateral stability. Longitudinal controllability. Maneuvering point. Fundamentals of aircraft dynamics.
