Best Aero Windshield Help...

[Giovanni LiCalsi]

I think the day will come when the rear steering on a Dymaxion car will be electro-mechanically controlled with gyroscopic and GPS sensors connected to a computer. Independent inboard front drive motors could add to the steering with computerized controllers that could help stabilize the steering in unison with the rear wheel.
I honestly think that the first series Dymaxion cars had so much of a front overhang that they became unsteerable in strong crosswinds.

One of the Dymaxions put 120,000 miles on the odometer. Cross-wind performance was managable but not what the normal driver would expect. They wanted to yaw into the wind instead of veering downwind.

They weren't even cars; but test vehicles for his Omni-Directional Transport tri-phibian. At high speeds the rear wheel was to lift off the ground with steering by rudder and drive from the two front wheels.



He anticipated (1933) turbojets that would let it lift off straight up like a Harier jump jet. His design for Kaiser had a variable wheelbase and 3 wheel power and steering.

I saw a Tesla Roadster up close and personal this morning and I immediately flashed on your project when I realized how narrow the canopy and windshield was.
I'm not sure of the dimensions,but it might be something Lotus could provide.

I went back to the first page to see what this was all about, and found the Porsche Speedster suggestion. It would be enlightening to find an autoglass provider willing to put one of each up on a countertop for evaluation.

No good for the street or strip

If the USFRA had allowed me to run it in 2012,I would have done the integration and figured out a way to transport it to,and attach it at Bonneville.But they said no dice!
For September this year,I'm going to make a sheetmetal or composite vignette of the wrap-around windscreen to test at DARKO.
R.G.S White gave it the A-Rating in 1968 and I want to see if it shows,drag-wise.
Here,VW is using the wraparound glass on their VW 2000 of 1980

Ditto for some of today's bigtime boy racers

(the evil Phil Knox has considered doing the integration anyway,installing the backlight as a 'bug-deflector' over the existing DOT windshield,with it's own wiper/washer system just to get some mpg data).And beg for forgiveness if any eagle-eyed constabulary catches on and wishes a roadside chat.
My biggest concern would be very weird internal reflections between the two screens.

Here's a shot from a higher vantage point which illustrates the plan curvature of the glass a little better

I've been looking lately at the Nissan IDS Concept. It's got these windsplits on the hood to partition the airflow over the windshield. They aren't as thin as the cut-line at the A-pillar makes them look.

I don't know what they're doing.But I'm doing the same thing on the T-100,without lowering the center/cowl area.
They may have cameras hidden in those areas at their trailing edges.

Oh man that is beautiful.

Real or Photoshop?
