So we're stuck in an era where:
- full wheel covers always gave the lowest drag
- lift was caused by separation
- airflow direction can be predicted by The Template
- rear spoilers 'reach up' to flow
- airflow separates at the end of the roof of notchbacks
.... and so on - all of which are wrong for any cars of the last 30 years. |
* what is communicated to the viewer when, a multi-billion dollar multi-national corporation, which could possess/ construct, the best technology imaginable, choose MOON discs when they attempt land speed records.
* You've yet to master the Bernoulli theorem, so I advise you to keep your mouth shut until you do. Your way out of your depth. Book sales be damned!
* The 'template' is a known quantity. It provides for fully-attached flow.
* All the spoilers listed in Hucho's 2nd-Edition were immersed in turbulence. And yes, they extend upwards through what would otherwise be turbulence, allowing the flow to intercept a target which will force the flow to follow a path of less severe pressure rise; and allow reattachment once the severe positive pressure is abated. Page - 61, ' One way to generate negative lift is a rear spoiler, the decisive feature being the relative height of 'separation' in relation to the rest of the body.' Hucho.
Page-282, 'negative lift values of... negatively inclined wings... increase with clearance above the body surfaces as they enter the ' undisturbed air flow.' ( what do you think Huchos' talking about? )
* Since notchbacks are a mutilation to a streamlined contour, one attempts to minimize the damage with whatever will pass muster with the stylist, designer, and production engineer. ( A Cd 0.22 notchback is not the same as a Cd 0.09 half-body ).
