Aerodynamic forces will alternately make it want to fly and dive into the ground.

The system should not have been unlocked until mach 1.4, because of the risk of aerodynamic forces moving the tail structure and creating 'an uncommanded feather', investigators said.

These stabilizing surfaces allow equilibrium of aerodynamic forces and to stabilise the flight dynamics of pitch and yaw.

Aeroelastic flutter occurs under steady flow conditions, when a structure's aerodynamic forces are affected by and in turn affect the movement of the structure.

The extreme subtleties of the aerodynamic forces on the light wooden boomerang make it surprisingly difficult to predict how the finished boomerang will perform.
