Flutter is one of the most dangerous phenomena of aeroelasticity. It is the loss of vibrational stability of an elastic structure when the aircraft reaches a certain speed, called the critical flutter speed. Exceeding the critical speed almost always leads to the destruction of vibrating units or the entire aircraft. Flutter flight test support is a combination of self-excited continuous bending and torsional vibrations of the wing, other structural elements of the aircraft, mainly the wing in flight, or the main rotor of the helicopter, arising when a certain speed is reached, depending on the characteristics of the given aircraft.
