MrMan Posted January 20, 2005 Share Posted January 20, 2005 Hello, I've been eyeing HC as it looks like a rather interesting series. I had a few questions regarding the technical regulations regarding aerodynamics for Hybrid Vehicles. If I could have a few clarifications to the meanings that would be greatly appreciated. 1.) 9.4(d), what is meant by it must retain the style (i.e. no air reliefs and no flares)? What exactly are air reliefs or flares? 2.) 9.4(f), what is meant by the diffuser tunnels can be at most 3 inches in depth? 3.) 9.4(h), what exactly is a front spoiler and a front splitter/undertray? 4.) 9.4(i), what is meant by 'cockpit and/or adjustable spoiler controls'? Please be extremely specific in the answers as it would be most helpful and very important. Regards and thanks in advance Quote Link to comment Share on other sites More sharing options...
0x1 Posted January 20, 2005 Share Posted January 20, 2005 I'll give this a shot. Anyone feel free to jump in and correct me if I've made a mistake. 1.) 9.4(d), what is meant by it must retain the style (i.e. no air reliefs and no flares)? What exactly are air reliefs or flares? 2.) 9.4(f), what is meant by the diffuser tunnels can be at most 3 inches in depth? 3.) 9.4(h), what exactly is a front spoiler and a front splitter/undertray? 4.) 9.4(i), what is meant by 'cockpit and/or adjustable spoiler controls'? Flared fenders (aka wide body kits) protrude further from the car and typically allow you to run wider tires or more offset for a wider stance and more grip. Air reliefs are holes/slits cut in the fenders, typically for the purpose of venting hot air out of the engine compartment or ducting air to the brakes. The diffuser depth is pretty self-explanitory. Diffusers are used to smooth airflow under the car and decrease drag. A front spoiler/splitter/undertray setup lets you alter the aerodynamics of the front end of the car. Typically, the goal is to make less air flow under the car and to make the air that flows under the car flow more smoothly. This gives you more downforce and less drag on the front of the car. If you want to see pictures of good setups, do a search on honda-tech for splitter. "cockpit and/or adjustable spoiler controls" refers to a spoiler whose pitch/attitude can be adjusted remotely via a switch (typically in the cockpit where the driver can reach it) Hope that helps - Scott Quote Link to comment Share on other sites More sharing options...
slammed_93_hatch Posted January 20, 2005 Share Posted January 20, 2005 Hello, I've been eyeing HC as it looks like a rather interesting series. I had a few questions regarding the technical regulations regarding aerodynamics for Hybrid Vehicles. If I could have a few clarifications to the meanings that would be greatly appreciated. 1.) 9.4(d), what is meant by it must retain the style (i.e. no air reliefs and no flares)? What exactly are air reliefs or flares? this means if you use a fiberglass or carbon fiber fender it must be an exact replica of the stock fender, IE you can not make the fender wider to accomodate tires, and you can not have something like the BMW Z3's have in there fenders 2.) 9.4(f), what is meant by the diffuser tunnels can be at most 3 inches in depth? This means that if you run a front diffuser/under try you can't have tunnels (that in some for of fluid dynamics that is above my comprehension allow air to move cleaning under the car) these can't be any longer then 3 inchs 3.) 9.4(h), what exactly is a front spoiler and a front splitter/undertray? THis is something that is placed under the front bumber, that is flat and creates down force on the front of your car, now here is the kicker WITHOUT introducing drag. If you go to google. And type in race car aerodynamic's you will find it VERY educational, thats how i found out all of this info 4.) 9.4(i), what is meant by 'cockpit and/or adjustable spoiler controls'? Ok you know the some times large aluminum wings/spoilers that you often see on honda's and other imports on the street? well on race cars they can be fairly effective at creating down force. Well unlike the front undertrays/splitter/spoilers/diffusers, almost all rear wings create drag when creating down force. So there might possibly be a benifit to having an adjustable wing, when you need down force pull the lever and in down force position, when you are on the stright away's or slow speed stuff and don't need the spoiler you flip the lever and position the wing to a position were it doesn't produce down force or drag. Please be extremely specific in the answers as it would be most helpful and very important. Regards and thanks in advance My answers are in bold. Andrie or some one else that has a fair amount of knowledge in this area, please chim in/correct/refine my answers. this stuff isn't my strong suit Quote Link to comment Share on other sites More sharing options...
MrMan Posted January 20, 2005 Author Share Posted January 20, 2005 What is an air relief? And thanks for the clarifications Quote Link to comment Share on other sites More sharing options...
