1. A control surface load simulation apparatus comprising:
a first support surface;
a second support surface apart from the first support surface in a height direction;
a control surface located between the first support surface and the second support surface;
an actuator connected to the second support surface and configured to apply a predetermined load to the control surface; and
a reaction force providing structure connected to the first support surface and the control surface to be movable relative to the first support surface and the control surface, the reaction force providing structure being configured to apply a reaction force corresponding to the load to the control surface,
wherein the reaction force providing structure includes:
a first stator rotatably connected to the first support surface;
a second stator disposed apart from the first stator;
at least one linear guide located between the first stator and the second stator;
a main mover configured to move along the at least one linear guide;
a movement guide connected to the control surface and the main mover to move the main mover according to displacement of the control surface;
a fixed guide having one end fixed to the first stator and the other end inserted into the movement guide;
a first spring on an outer circumferential surface of the fixed guide; and
a second spring on an outer circumferential surface of the movement guide, and
wherein the control surface is rotatable about a hinge axis, and a central axis of the actuator and a central axis of the reaction force providing structure are spaced apart from the hinge axis and eccentric to each other; and
wherein the fixed quide is configured to pass through the main mover and is inserted into an inner space of the movement quide, which is hollow.
