Reverie Universal Fit Motorsport 110mm Chord Rear Wing Data

110mm stand alone wing profile. Universal fit rear & Lotus specific rear wings.

Designed by Aerodynamics writer and designer Simon McBeath (author of Competition Car Aerodynamics) for ReVerie using Fluent Flowizard software. Data and images generated by the CFD software are displayed below.

Two universal fit designs are available, either a straight design or a curved design with a 1600mm radius (chosen to suit lotus Elise type models).

The wings feature internal longitudinal stringers and end spars with 2 x M6 threaded inserts for mounting between supports or for affixing end plates. The wings come ready to mount between supports on the end spars or can be supplied with underside double or single shear carbon fibre mounting plates.

Ordering details:

You need to tell us straight or curved profile, mount position (front under slung mounting tabs or underside tabs), the required span of your wing and the distance between the lower mounts (inside to inside on wing) if you require, the distance between the outside of vehicle mounts and vehicle mount thickness if you want a double shear fixing (unless you would rather fit the mounts to the underside yourself) and if you would like the optional 5mm or 10mm high gurney flap (these can be purchased later if required). New end plates are also available separately if they become damaged

Air speed 44.7m/s (100mph) freestream

Tuning Advice

The recommended maximum angle of attack with this wing in free stream air is 20^O, although this may be different when mounted on a car. Forces increase with span width as per tables above. The rise in the forces at speed is in line with the square of the velocity increase. Thus, to calculate forces at different speeds within the range bracketed here simply multiply by the square of the ratio of the speeds in question. Below 100mph some caution should be used when applying this square law, but approximations of forces down to perhaps 60mph or 70mph will be valid. A 5 or 10mm Gurney flap could be added to further add a reasonably efficient increment of down force. All the results obtained were from evaluations in free stream air, with horizontal onset flow to the wing. This is obviously not representative of the onset flow on the back of a car. Nevertheless, the generic findings of this project should be valid.

To Scale a force to a different speed.

We will use the Notched end plate design figure at 100MPH from above. Then scale it to 150MPH.

New Force (N) = Original Force (N) x (New Speed² (MPH) ÷ Data Speed² (MPH))
New Force = 937.2 x ((150 x 150) ÷ (100 x 100))
New Force = 937.2 x 2.25
New Force = 2108.7
