The pitch moment of inertia is defined as the sum of the products of each small mass element in the aircraft and the square of its perpendicular distance from the pitch axis.
- ib: This represents the pitch moment of inertia, which is a measure of an aircraft’s resistance to changes in pitch motion. It quantifies how the aircraft’s mass is distributed about its pitch axis. A higher ib indicates greater resistance to pitch changes.
- Iyy: This represents the moment of inertia about the pitch axis (y-axis). It is a measure of how the mass of the aircraft is distributed along the pitch axis.
- m: This represents the mass of the aircraft, which is the total mass of the entire aircraft, including its structure, payload, and fuel. It is typically measured in kilograms (kg).
- lt: This represents the wing span squared. It’s a measure of the length of the wingspan of the aircraft, squared (lt^2).
