Rice =/= JDM Among things, that look was popular in America before most American 'import tuner scene' folks had heard the term JDM. The shape of flares, your hood, your roof, etc can add downforce, but those, and the wing or spoiler on your car don't operate 'in ground effect' typically. A low mounted wing that works in tandem with your diffuser might, but those aren't too common outside of sports prototypes, most tintops seem to get rear wings that are mounted too high for that to be the case. Mounting it high makes sense to remove it from 'dirty' air flow, but if the car allows it to be mounted low enough to work with the diffuser it makes sense to mount it there, you give up a little bit of downforce (but less than one might expect if you're thinking of the wing in isolation) but you reduce drag significantly at the same time. Never heard of a Flarecraft, but I am familiar with ekranoplans like the Caspian Sea Monster. |

It appears to me they are in the same category, the primary difference being size and use. I had not heard of Ekranoplans...took me right to the same Wiki reference. Large, military transports using ground effects principles primarily over water. Flarecraft are smaller, civilian pleasure craft using ground effects principles primarily over water. Interesting to see the Ruskies were playing with these craft in the 70s, and they went largely unreported in the west at that time. Which coincides with when I learned of the development of Flarecraft in the states, which was touted at the time as the next big leisure activity...not quite boating and not quite flying while combining elements of both. It didn't catch on, and folks flocked to the new personal water craft (jet skis and jet bikes) instead. ![]() From the Wiki:
https://en.wikipedia.org/wiki/Ground_effect_vehicle I quote this here regarding the Caspian Sea Monster to further make my point: "it was designed to travel a maximum of 3 m (9.8 ft) above the sea," which is that layer of atmospheric interaction with the surface that provides the "cushion" that provides "ground effects." I'm hard pressed to think of *any* non-airplane racing vehicles that operate normally at greater than 3 meters above the ground. Perhaps some dirt bikes in a motorcross, perhaps some offroad vehicles in an endurance race spend *some* time at that altitude, but most racers typically inhabit that boundary layer as a matter of course. Hence my opinion. In the grand scheme, it is merely words and doesn't really matter. |

Ground effect isn't determined by height from the ground, it's determined by height from the ground relative to the wing's chord. An ekranoplan with stubby, deep wings might still be in ground effect much higher off the ground than a craft with a narrower wing chord. That's why a race car wing isn't operating in ground effect even if it's less than half the distance from the ground compared to a wing-in-ground-effect craft. That flarecraft looks pretty fun. |

Yes. But even a regular pedestrian 99 Civic that was made to be sold in Japan is JDM. It really just means (made to be sold in the) Japanese Domestic Market. If Eddie Bauer (or whatever cobranded vehicles) Explorers were only made for the US because that's a recognizable name here, then someone in Europe that imported one might be driving around talking about their USDM vehicle. |

Expanding from this, your (hypothetical) Acura DC2 with the bug-eyed front is USDM, and if that person trades front sheet metal with a Japanese Honda DC2 owner, the Japanese Honda DC2 owner did a 'USDM conversion' the American Acura owner did a 'JDM conversion'. Further, nation of origin isn't relevant, GM has sold JDM Camaros (among vehicles), Volkswagen has sold JDM Golfs and Polos. |

Here in Eastern PA, the term JDM is affiliated with the company James D. Morrissey, Inc. They have been in business for almost 100 years and they are the largest union Heavy Highway Builder in the region. They pretty much built every major road, and highway in Eastern PA. They also have a ready mix concrete division called JDM Materials, Co. http://jdm-inc.com/ https://www.instagram.com/jdmmaterialscompany/ |
