Description
The majority of the ten-week internship was spent designing a servo mounting device, and a collective control system for the Forward Flight Aero Test (FFAT) stand. The servo mounting device uses four threaded standoffs along with a top plate, held together with screws, that raises the servos above the protruding threaded rods and screws. The collective control system is a rectangular block that attaches the swashplate to the servo arms connected to the servo motor. This control rod is used to translate the rotation from the servo arm into collective control for the blade angle. The control rod has two holes for shoulder bolts that connect it to the non-rotating swashplate and the servo arm. The control rod, servo mount standoffs, and top plate are all currently made from steel 17-4 PH. The screws that attach the top plate to the standoffs are made of black oxide alloy steel, while the shoulder bolts are composed of 18-8 stainless steel. The largest allowable force on the designed system is 50 N, since that is the force at which the standoffs fail under FEA.
