Brief Description: Designing Brackets For Trim Linear Actuator
I am implementing a modification to the AeroConversions manual dial nose trim system. The cable and spring design remains the same, but I will incorporate an electric linear actuator to produce the cable movement vs the manual dial rotation. I am starting with a Utility Linear Actutaor from Firgelli Automation, model FA-U-110-12-6, a six-inch travel actuator, operating on 12 volts, able to handle 110 lbs of force. This is a little more travel than the 4 inches of travel provided by the original manual trim system.
Designed and layed out intial tests files for cutting the mounting brackets for the electric linear actuator modification for the nose trim system.
Using 1/2" thick Corian acrylic countertop material, I made three iterations of the cut files for the mounting brackets, slightly adjusting the mounting opening on each iteration and test fitting to the actuator barrell.
Once the brackets files were finalized for fit, I layed out the cable attachment end for the linear actuator rod. This was cut from 1" thick black Delrin.
Both the brackets and the cable attachment piece were drilled and tapped as required for hardware and function.
Acrylic test brackets installed on the actuator arm.
