4 drafts of plan makes for a change!


10 March 2007 the chassis is almost ready to go to the next phase. Then we noticed the tail section was rather large, so we went back to the original drawings and guess what? Yes it is to0 large ! It would seem that the drawings varied from inside measurements to centre line measurement as they were changed from one type of format to the next. Perhaps we should have checked that detail as per our overall plan but, Oops! The fix is simple make the car longer so that the tail is carried on to the planned dimensions where the chutes are located. This will mean changing the length too maintain the 7 degree angles by 16.5". That will make the car a little over 28'6" and increase the lateral stability. pictured is Werner And Andrey mocking up the changes. We are still deciding whether to use Tube chutes or drop chutes to stop the car. A lot of knowledgeable folks in the Land speed community have suggested launching from the tubes is best and some say dropping is OK with the small tail of the car. I am accustom to dropping the chutes on the dragsters and like that the chute is out in the air immediately on release. I am going to talk to the manufacturer, but I am leaning toward mechanical launched tube chutes. Thanks to Sean for helping today & Andrey who also is donating his day off tomorrow to caught up to schedule.
