Abstract
A linear actuator for use with a fan with deployable fan blades to deploy the fan blades when in use and stow the fan blades when not in use. The linear actuator utilizes a drive element having a driver that moves linearly along a shaft of the linear actuator. Linear movement of the driver causes radial movement of arms connected to the linear actuator and the fan blades. Radial movement of the arms causes rotational movement of gears attached to the ends of the fan blades to cause the fan blades to rotate into the deployed or stowed configuration.
