Another finless rocket, maybe yes and maybe no

Another finless rocket, maybe yes and maybe no

Well, KenECoyote has unveiled another finless rocket concept that has tickled my fancy - an Apollo Command/Service Module. I love its stubbiness and that big nozzle. I have my doubts on the feasibility of making this a finless rocket. However...I downloaded a 1:48 scale paper model with the intent of using it as skins. This came out to be about 3.25" in diameter. Rather than making a tube or fiddling with the scale of the printout, I am just adapting the wraps to a 3" mailing tube. The lower part of the capsule section will be left off and will expose the 6 strakes that will center a BT-60 in the 3" tube. These will extend a half-inch below the body. The bottom will be solid and thus air entering the top will be pushed out sideways at the base. This is Ken's 'RAIS' concept,I will build it, add nose weight and re-mindsim the concept. If the probability of success seems to more than 25%, it will stay finless. If not, I'll punt and kludge some fins.The dimensions are not right and the mass distribution is way off, but here is a cut at modeling it in RockSim.
