Asst Marine Dwg 390-01 Rudder Stock.pdf

This is a technical engineering drawing document for a 390 Rudder Stock modification dated December 2, 2013. The drawing set consists of six sheets and provides detailed specifications and modifications for an aircraft rudder stock assembly.

Sheet 1 illustrates rudder stock reactions at a 1/32 scale, showing the overall assembly with the tiller, upper and lower rudder sections, and critical dimensions including the 15.768-inch distance to the tiller, 114.874-inch main section height, and 118.330-inch total length. Sheet 2 details rudder stock modifications with existing and new dimensions, specifying a new tiller design and a new inside radius of 0.25 inches minimum, along with tapered transition requirements (1:3 ratio). The modification notes reference calculation 1-11 and indicate a 334.281-inch above-waterline baseline. Sheets 3 through 6 present detailed weld group specifications and structural components, including cylinder foundation welds (Groups A-D), carrier foundation plate bolt group specifications (8 pc M30 bolts), structural elements under the carrier foundation plate (Weld Group H), tiller stop section welds (Weld Group I with tie plate welds), and tie-bar end weld groups with specific area and section modulus calculations. The drawings include precise measurements in inches with tolerances, material specifications, and cross-sectional area data essential for fabrication and structural analysis of the rudder stock assembly.
