Abstract
A skew sensing apparatus for detecting skew in at least one, or a plurality of control surfaces of a vehicle. The apparatus includes a tension cord which is held under tension between a) a first spring associated with a sensor and a sensor target and b) an opposing second spring. During normal operation, the apparatus is configured to maintain said sensor target in a first position relative to said sensor, thereby indicating said normal operation. During an abnormal operation, the apparatus is configured to shunt said tension cord such that said sensor target is translated to a second position, relative to said sensor thereby indicating said abnormal status.
Claims11
A skew sensing apparatus for detecting skew in at least one, or a plurality of control surfaces of a vehicle, the apparatus comprising:
- a tension cord which is held under tension between:
- a) a first spring associated with a sensor and a sensor target;
- and
- b) an opposing second spring;
- wherein during normal operation, said apparatus is configured to maintain said sensor target in a first position relative to said sensor, thereby indicating said normal operation;
- and
- wherein, in an abnormal operation, said apparatus is configured to shunt said tension cord such that said sensor target is translated to a second position, relative to said sensor thereby indicating said abnormal status;
- wherein said first spring provides a lower opposing force to said second spring.
