spacesailor Posted June 22, 2019 Share Posted June 22, 2019 "all of them had to be parked to cool off after the test drive", New take on "over-heating" One motor-group (club ish) is gluing fins onto oil-pans & filters. Seems to be for towing/going up steep hills, & they say it Works. Trolley buses should have been used in Sydney !. spacesailor Link to comment Share on other sites More sharing options...
onetrack Posted June 22, 2019 Share Posted June 22, 2019 Spacey, you can purchase aftermarket alloy diff housing covers, and transmission pans, with fins cast into them. In the case of the Ford 6R80 transmission, you can purchase a deeper aftermarket oil pan with fins, that holds an additional 3 quarts (2.8L), which reduces transmission operating temperature, not only via the fins, but via the additional oil capacity, as oil does as much cooling as it does lubrication.

turboplanner Posted July 7, 2019 Share Posted July 7, 2019 https://www.avweb.com/aviation-news/airspeeder-racing-coming-in-2020/ should be be interesting to see how people react to the prototype Another fantasy. Car race tracks are still in existence because we built safety fences and catch fences to protect spectators from flying debris. Flying above a race car circuit would certainly provide a ready-made venue with parking, seating, eating, toilets etc, but there's no way the aircraft could race above them safely. In some cases there may be tracks where the aircraft could fly outside the circuit so centrifugal force threw any failed aircraft outwards into open land. Electric RC competition aircraft are sensational to watch because they are so fast, and slot cars were like lightning, so there's no doubt spectacular speeds could be achieved with powerful motors and short races.

facthunter Posted July 7, 2019 Share Posted July 7, 2019 Make for interesting collisions at some stage. Well we do have plenty of oil tankers on the road but I try to keep well away from them. nev Link to comment Share on other sites More sharing options...
onetrack Posted July 7, 2019 Share Posted July 7, 2019 Batteries in EV's pose no more fire threat than perforated petrol tanks. The vehicle designers smartened up their act probably 3 decades ago, in relation to improving fuel tank protection, after quite a number of lawsuits related to fuel tank fires, caused by poor placement of fuel tanks, and inadequate tank protections. The same design criteria are applied to battery placement in the EV's, it is well protected, and will only get badly damaged in the very worst of high speed major collisions with solid objects, or head-on collisions.

facthunter Posted July 7, 2019 Share Posted July 7, 2019 Yes, It's of similar magnitude but the anti electric mob will seize on it when it happens. It will be like a miniature atomic meltdown rather than an oxygen fueled "normal" type event with flames over a largish area. Nev Link to comment Share on other sites More sharing options...
spacesailor Posted July 7, 2019 Share Posted July 7, 2019 Just a note !. " Batteries in EV's pose no more fire threat than perforated petrol tanks." Race car's run alcohol, not ethanol/petrol like road users. spacesailor Link to comment Share on other sites More sharing options...

EVs don't pose any higher risk than ICE cars in that respect, but they need a new breakthrough in battery technology to avoid thermal runaway, where there have not been just a few, but many spectacular fires from EVs already. Unless they can can get a battery design breakthrough there will inevitably be design rules in reaction to the fires. Same reason we're seeing the current pause in autonomous car development until computer capacity can be found to avoid all types of collisions, not just the most obvious - crashing into the car in front etc. Link to comment Share on other sites More sharing options...
