Abstract
An aerodynamic blade for a motor vehicle includes a shutter mounted on a support shaft having an axis and connected to a chassis of a vehicle by at least one support, and driven in rotation around said axis between an open position and a closed position by a motor assembly. The motor assembly includes one or more elements configured to accumulate mechanical energy and having an adjustable stored energy level to meet a demand for a sufficient torque to change a position of the shutter in a time of less than one second.

An aerodynamic blade for a motor vehicle, comprising:
- a shutter mounted on a support shaft having an axis and connected to a chassis of a vehicle by at least one support and driven in rotation around said axis between an open position and a closed position by a motor assembly,
- wherein said motor assembly comprises a torsion spring oriented along the axis of the support shaft and configured to accumulate mechanical energy, and
- wherein a level of energy stored by the torsion spring can be adjusted to meet a demand for a sufficient torque to change a position of the shutter in a time of less than one second.
