This car is beginning to look more and more conventional.

DW

Hi DW...The look is a function of the application using feedback I've received from forum members.  This latest version is designed to meet SCTA rules so that testing can be done at their events as Sumner and jacksoni wisely suggested.  We may learn that "conventional" body geometry is sufficient to achieve record speed with the power train as designed so the added costs of the encapsulated driver and video system may not be needed for the first effort should we get that far.  The Cd results should tell us if that's true or not.  Thanks...

The trick is to get everything within that envelope.

Hi Neil...yes that's true.  I believe I've been able to scale all the major systems within the envelop.  The wiring and plumbing I've taken into consideration and space is allocated for that routing.  The power cables running from the generators to the controllers runs between the raised tubing in the chassis floor and the flat floor pan running the length of the chassis. The short run of cables from the controllers to the wheel motors snakes within the tubing entering the motors behind the wheels.  Oil, methanol, glycerin, and dielectic fluid to cool the controllers are contained in the combo tank/intercoolers.  Dry sump components for the IC engines are mounted adjacent to the generators and central oil tank/intercooler.  The fuel system will be fed by a Waterman pump running off the nose of the forward 4 rotor.  The engine control modules will ride in the flat space above the drivers foot well.  There are no radiators or mechanical brakes.  Cooling is via the chilled fuel and oil, and braking is via the chutes and measured reversal of the electromagnetic field driving the wheel motors.  Thanks Neil...

Yes it is,  but the "conventional" vehicles it is being compared with took many years to get "conventional" as well.  Design without experience is dangerous.  There still may be some packaging advantages that will allow some improvement in cd.  As you know the faster you go the more important that becomes with limited traction.  The CFD drag predictions will be interesting. Hopefully reduced surface area (skin drag) and shape will show some improvement.  If the front skirts are effective at creating some down force the drag will be higher than the skirtless design but final weight distribution and rear drive only may make the shirts unnecessary.

From my crazy uncle in Red Bluff:


The Washington Redskins finally drop their offensive name.  Dan Snyder, owner of the NFL Redskins, has announced that the team is dropping "Washington" from the team name and the team will henceforth be simply known as "The Redskins".
 
It was reported that he finds the word “Washington" imparts a negative image of poor leadership, mismanagement, corruption, cheating, lying, and graft, and is not a fitting role-model for young fans of football.

 cheers

Mike

Here is a scaled size comparison between Simspeed 4.4 and the Challenger 2 and Turbonator II.  All three cars are scaled in inches based on info on respective websites.  The standing man model next to D. Thompson is scaled to 6'2 which looks correct compared to the Challenger II crew members.  All 3 cars are set equally at ground height.  The biggest difference (frontal area) would be most noticeable from and head on view but I couldn't find correct perspective photos of the other cars to make that comparison.  I didn't find any dimension info on the Speed Demon in order to scale that car for comparison so i left it out.

I hadn't heard AOC was dumb; is that real? Next thing someone will tell me Trump is dishonest. No, maybe not on this forum.

Back on topic...…………...Marybeth asked me what IDK stood for ….I told her " I don`t know"...She said  " Well darn...I thought you would …."

What!!??  You're a blonde?  I never would have guessed.   afro
