Picking through my second reading of Hiscock and trying to sub my numbers (no surprise) I have problems. His data for the Dox is RN=10,000,000 and my calculations show my bird has RN=1,000,000. (row 7) I am trying to calculate the total drag for HP required in climb at best L/D along with reading along with Hiscock. I do not have the airfoil data for my bird but do have the Glide polar. I would think one could calculate the total Drag with the glide polar. Looking at a spread sheet with the expressions, the questions arise. Maybe one could point to a thread on the site, surly it has been discussed. [FONT=&] [/FONT] 1: rows 8, 12, 13….if the glider is sinking ….. they can not all be correct? 2: row 13, 9 same question
