The objective of this chapter is to describe the forces and moments that act on a MAV. Following [5], we will assume that the forces and moments are primarily due to three sources, namely, gravity, aerodynamics, and propulsion. Letting **f**_{g} be the force due to gravity, (**f**_{a}, **m**_{a}) be the forces and moments due to aerodynamics, and (**f**_{p}, **m**_{p}) be the forces and moments due to propulsion, we have

where **f** is the total force acting on the airframe and **m** is the total moment acting on the airframe.

In this chapter, we derive expressions for each of the forces and moments. Gravitational forces are discussed in section 4.1, aerodynamic forces ...
