Abstract

An ice-management method for an aircraft includes scavenging torque from a mast of the aircraft with a system that is configured to provide an ice-management capability. The method includes using the scavenged torque to impart a vibratory force to an arm of the system and imparting the vibratory force from the arm to an inner surface of a spinner of the aircraft via a contact of the arm.

First claim

What is claimed is:

1. An aircraft-based ice-management system, the system comprising:
a base configured to attach to a mast of an aircraft;
a movable mount movably coupled to the base; and
an arm with a first end configured to attach to the movable mount and a second end comprising a contact configured to contact an inner surface of a spinner of the aircraft;
wherein the base comprises a track disposed on a face of the base; and
wherein the movable mount comprises a foot configured to fit within the track and movably secure the movable mount to the base.

2. The system of claim 1 , wherein the track has an elliptical shape.

3. The system of claim 1 , wherein the track has a circular shape.

4. The system of claim 1 , wherein the track has a center that is coaxial with a central axis of the mast.

5. The system of claim 1 , wherein the arm comprises a damper disposed along a length of the arm.

6. The system of claim 5 , wherein the damper comprises a spring.

7. The system of claim 1 , wherein the arm is configured to contact the inner surface at midpoint of a height of the spinner.

8. The system of claim 1 , further comprising a second arm with a first end configured to attach to the movable mount and a second end comprising a contact configured to contact the inner surface of the spinner.

9. An aircraft-based ice-management system, the system comprising:
a bearing with an outer race and an inner race, the outer race configured to attach to a mast of an aircraft;
a channel adjacent to the outer race and comprising a feature disposed within the channel, the feature configured to impart a force to an inner surface of a spinner; and
an arm with a first end movably attached to the channel and a second end comprising a contact configured to contact the inner surface of the spinner to apply a vibratory force thereto.

10. The system of claim 9 , wherein the feature comprises a depression configured impart a force to the first end.

11. The system of claim 9 , further comprising:
a lockout pin configured to engage a hole formed through the first end of the arm; and
wherein the system is disabled when the lockout pin is engaged with the hole and the system is enabled when the lockout pin is disengaged from the hole.

12. The system of claim 11 , further comprising a clutch and an actuator that is coupled to the lockout pin and configured to engage and disengage the lockout pin with the hole.

13. The system of claim 9 , wherein the arm is configured to contact the inner surface at midpoint of a height of the spinner.

14. An ice-management method for an aircraft, the method comprising:
scavenging torque from a mast of the aircraft with an ice-management system;
using the scavenged torque to impart a vibratory force to an arm of the ice-management system;
imparting the vibratory force from the arm to an inner surface of a spinner via a contact of the arm;

wherein the ice-management system comprises:
a bearing with an outer race and an inner race, the outer race configured to be attached to the mast of the aircraft;
a channel adjacent to the outer race and comprising a feature disposed within the channel, the feature being configured to impart a force to the inner surface of the spinner; and
an arm with a first end movably attached to the channel and a second end comprising the contact configured to contact the inner surface of the spinner to apply the vibratory force thereto.

15. The method of claim 14 , wherein the feature comprises a depression.
