jt - b2 and b2 300

grabcad

These are the first two car bodies i've ever modeled - i've modeled individual car parts before but never bodies.I will be very greatfull for any feedback, especially constructive critques.NOTES:When i first saw this competition i knew i cannot compete based on design alone as i'm not good at it (i'm an engineer not a designer), so i decided to let aerodynamics and mechanics guide the design.The result is far more eye-pleasing than i anticipated, but (to me) also quite conservative looking.If time permits i will make another design to mend this.As requested 'B2 Spirit' and 'B2 Spirit 300' use the same main chassis/body, only the bumpers and gas caps are different.And as requested the canopy is largely uncovered.The nearly seamless look could be achieved with a translucent plastic canopy frame, as long as the bottom and back edges are braced by a sufficiently strong frame (assuming the glass itself is strong enough, which it likely is if aerospace grade glass is used).B2 SPIRIT 300:The CFD was made at 125 m/s (~280 mph).Due to time and resource constraints i have, it is static (non-transient), has a medium-fine mesh and uses simplified wheel-rims and tires, hence it's accuracy is limited. However, if i may say so myself, the model is decently streamlined for the first iteration of the process.Due to the constraints mentioned above, my aerodynamic profiles (applies for 'B2 Spirit' as well) are simple airfoils made of 3-4 circular sections, instead of actual aerospace airfoils. Changing this alone would make a considerable difference on the airflow.The biggest area for improvement is the rear bumper, which needs stronger tapering towards the diffuser.The second major area for improvement is the front bumper which is still pushing too much air despite the smooth, low contours.The third thing is the model needs viable seagull-door hinges modeled (applies to B2 as well).On one picture i added a decale of shark teeth/mouth in the Spirit of American warplane tradition; besides, with the central fin this model does somewhat remind of a shark.B2 SPIRIT:Looking from the front the car kind of has a smiley look, it is a love it or hate it kind of look.If time permits me i will make a facelift version.CREDITS: the Nevada road picture, used as the background in the picture of B2 300 with parachutes, is a free to use picture from pixabay.comp.s.: while uploading this, i read the latest comments and guidelines, seems my models do not comply.Still, feedback greatly appreciated.
