Does Solidworks allow for aerodynamics modeling?

it does, but it is limited. some simple testing and hand calculations will probably be more useful.

It's an interesting start and worth looking into more carefully for sure. That pod could have great utility even pared down for those that don't require the bike clearance. 5-10 gallon fuel cells that are removable for cargo, for instance. Like you said, CG, parasite drag, exhaust and cooling considerations along with stress analysis would be needed but the idea is so darn creative. Thank you for going through the mental exercise. Hopefully some of the engineering folks will kick in some thoughts.

I'm just curious why you'd want the bicycles in the pod when both Bromptons will fit in the RV7/9 baggage area. It seems that the luggage (suitcase and/or duffle bags) could be narrower/shallower and easier to slip into the pod. Or give you the option to make a shallower pod.

Have you considered shortening the pod to accommodate one of the bikes and load the other in the baggage compartment? Some items that normally would be stuffed in the baggage compartment could then go underneath in the pod. Might be able to change the pod dimension a bit to increase the ground clearance. Good luck with the idea.

that may be possible but I am really trying to get both in the pod. the bikes can be maneuvered on the ground and then shoved into the pod through the aft door. hopefully, that would be easy enough to do. I'm thinking minimal effort.

I would be worried about cooling air flow. There will be no free stream at the cowl outlet anymore, with a lot of turbulence. Not an aero Engineer but would want someone to tell how badly this would affect flow through the cowl.

yep, that's the first order of business. how much room do you need? a bifurcation built into the pod may be of some benefit.

Default Two Pods?

How about two pods tied in at lower fuselage corners and 9A gear legs? Have to have some flex in the connections to absorb the relative motions on bad touchdowns. Clear up some airflow down the fuselage center line.
