I've played around a bit with the design, and come up with the suggestion that it's not necessary to have the cap be a perfect arch at the rear. It can approach, say, 80% of an arch, still be round enough, still allow a maximum flow angle of no more than 15%, and narrow the rear face area to around 2 square feet.


Thank you
