Stability

^[G] = Glossary link

    We can talk about stability for both Flight Dynamics^[G] and Aeroelasticity. In fact, stability is a branch of mathematics that checks if a solution of a differential (or a set of simultaneous differential, no matter ordinary or partial) equations grows or diminishes with time. If it grows the system is said to be unstable. If it diminishes, then it is stable. If it remains to be the same, then it is in between, but we usually call this marginal stability. Solutions in both Flight Dynamics and Aeroelasticity can grow or diminish, so stability is a concern in both disciplines. One important point is that to check stability, we don’t have to find the solution to the differential equations; there are methods that we can use to make stability conclusions without solving the differential equations.

    The whole point of modeling an aircraft is to ensure its stability in flight.  Modeling software of today does this by executing calculations based on the concept that the wing is perfectly rigid.  This page focuses on the conventional model; for our new model which accounts for aeroelasticity, see the Aeroelasticity + Stability page.
