Cable Pulley Test

This report will investigate the interactions regarding a cable pulley system within the nose landing gear. There is the possibility of tension drops occurring within this system. A test was done to determine the tension values within the system, this test was to isolate two possibilities that could

cause the tension drop. These two possibilities were structural deflection within the nose landing gear or the tension loss occurring within the pulley cluster. With this test it was found that there are in fact tension drops when the pulley cluster was used on a rigid system without the structural deformations of the nose landing gear. There are some discrepancies where a basic cable test was done without the pulley cluster and no tension drop was found. This would lead to an investigation to occur after this test

to determine why the tension drop happens with the cable and pulley cluster interaction. Some reasons to the tension drop within the pulley cluster would be unwinding of the cable as well as deformation occurring. There is however no definite answer for the tension drop as the observation was difficult within such a confined and small space of the pulley cluster.
