Abstract
An automated method for influencing a gust load of an aircraft is provided. A torque at least of an electromotive thrust generating unit arranged on a wing of the aircraft is modified such that a root bending torque of the wing generated by the gust load is reduced. An associated apparatus, an aircraft, a computer program product, and a computer-readable medium for carrying out the method are also provided.
Claims14
An automated method for influencing a gust load of an airplane, the automated method comprising:
- ascertaining, by a sensor system, an acceleration of a wing of the airplane perpendicular to the wing, the wing having a wing root, and the acceleration being a value proportional to a root bending moment of the wing generated by the gust load;
- and
- changing a torque of at least one electromotive thrust generator arranged on the wing of the airplane based on the ascertained acceleration, such that an opposing torque introduced into the wing by the changing of the torque causes a bending moment at the wing root to compensate for the root bending moment of the wing generated by the gust load, such that the root bending moment of the wing generated by the gust load is reduced via the opposing torque.
A device for influencing a gust load of an airplane, the airplane having at least one electromotive thrust generator arranged on a wing of the airplane, the device comprising:
- a sensor system that is configured and programmed to ascertain an acceleration of the wing of the airplane perpendicular to the wing, the wing having a wing root, and the acceleration being a value proportional to a root bending moment of the wing generated by the gust load;
- and
- a controller configured and programmed to change a torque of the at least one electromotive thrust generator based on the ascertained acceleration, such that an opposing torque introduced into the wing by the change of the torque causes a bending moment at the wing root to compensate for the root bending moment of the wing generated by the gust load, such that the root bending moment of the wing generated by the gust load is reduced via the opposing torque.
An airplane comprising:
- at least one electromotive thrust generator arranged on a wing of the airplane;
- and
- a device for influencing a gust load of the airplane, the device comprising:
- a sensor system that is configured and programmed to ascertain an acceleration of the wing of the airplane perpendicular to the wing, the wing having a wing root, and the acceleration being a value proportional to a root bending moment of the wing generated by the gust load;
- and
- a controller configured and programmed to change a torque of the at least one electromotive thrust generator based on the ascertained acceleration, such that an opposing torque introduced into the wing by the change of the torque causes a bending moment at the wing root to compensate for the root bending moment of the wing generated by the gust load, such that the root bending moment of the wing generated by the gust load is reduced via the opposing torque.
A non-transitory computer-readable storage medium that stores instructions executable by a controller to influence a gust load of an airplane, such that the instructions cause the controller to perform:
- ascertaining, by a sensor system, an acceleration of a wing of the airplane perpendicular to the wing, the wing having a wing root, and the acceleration being a value proportional to a root bending moment of the wing generated by the gust load;
- and
- changing a torque of at least one electromotive thrust generator arranged on the wing of the airplane based on the ascertained acceleration, such that an opposing torque introduced into the wing by the changing of the torque causes a bending moment at the wing root to compensate for the root bending moment of the wing generated by the gust load, such that the root bending moment of the wing generated by the gust load is reduced via the opposing torque.
