Tight Cowl

grabcad

In my third attempt, I focus on reducing weight, frontal area, and skin while adhering to manufacturing requirements. My initial posts featured artistic designs. Recently, I employed a CAD program for this project, having first encountered CAD 40 years ago. For inspiration, consider the tight cowls of radial exhaust stacks on a Focke-Wulf Fw 190 and those of Pratt & Whitney PW 4360 engines in a commercial Stratocruiser. My goal is an eventual 18-cylinder application. The design is complete, but merely stable; it can be rolled to evaluate lifter cylinder positions within and without the case. I occasionally pause for reflection and create renders in Poser with figures to maintain man-rated standards.
