Can we tune the capsule geometry for betteraerodynamics - not a constant cross section?

How will it change with different back tail design (lifting tail)?

Should it be axisymmetric (revolution object)?A circular cross-section will lead to better aerodynamics.why??

Front opening needs to be circular like that of an aircraft jet engine for improved aerodynamics.WHY?

Exhaust of the air bearings will have to be controlled carefully to ensure proper capsule aerodynamics.

Above analysis based on some assumptions(refer hyperlooptech)Not for top speed but 470 mph(top speed-760 mph)

Assumptions:1. Capsule moving at 210 m/s, i.e. at 470 miles per hour2. Mass flow split assumed as: 50% sucked by fan, 50% goes around the capsule.3. Air sucked by the fan is then distributed at 40% from the tail and remaining to the air bearings.Diffuser needed if top speed more than mach 0.65Try using MDAO code?Read about inlets in Mattingly
