This years Members Meeting saw demonstration runs of the Ground Effect F1 cars that raced between 1978 and 1983.
These Ground Effect cars were developed to take advantage of the Bernoulli principle, whereby the gap between the ground and the cross sectional underside of the car is reduced to maximise downforce. By minimising that gap between ground and car, the air underneath accelerates faster than the air above and creates that pressure system that sucks the car to the ground, increasing grip and cornering speed.
In 1983, the whole Ground Effect system was banned due to the ever increasing cornering speeds that these cars could achieve. Concerns were raised that if the force was suddenly removed, the cars would lose all grip and have an accident (similar to what can happen today if an F1 car loses a rear wing suddenly).
In 1979, Arrows ran their A2 design, a car that had huge downforce but no wings, leading to some handling problems. In 1980, designers Tony Southgate and David Wass developed the A3 model, based around an aluminium monocoque chassis and the Cosworth DFV engine. In-board suspension was used to provide the largest possible ground-effect tunnels and the front and rear wings were used to provide a better handling balance.
Overall Arrows took 7th place in the 1980 F1 season with drivers Jochen Mass and Riccardo Patrese, with a best finish of 2nd at Long Beach.
This shot of the Arrows Cosworth A3 was taken after the demonstration run as the cars were filing back into the paddock.

On March 31, 2021 hard working A-RTS 2143 032 was the power for train 61880 from Wels to Braunau loaded with aluminium. It was eagerly awaited by a group of photographers while slowly climbing the grade to Pram-Haag.
Am 31. März 2021 kam die kurzfristig von RTS angemietete A-RTS 2143 032 vor dem Aluminiumzug 61880 von Wels nach Braunau zum Einsatz, der unter Verantwortung des EVU S4YOU verkehrte. Bei Pram-Haag bot sich den wartenden Fotografen ein ziemliches Spektakel, wo der Dieselveteran mit dem schweren Zug auf der Steigung ziemlich zu kämpfen hatte. (6001)

Drapeaux en aluminium, pleins et perforés, qui rendent hommage à la longue tradition bourguignonne des toitures à tuiles polychromes.
Created for the Crazy Tuesday theme of Aluminium Foil.
I covered an ornamental fish with crumpled aluminium foil and then coloured the image using Photoscape Colorfill.
Die beiden Novelis-Maschinen 189 990 und 994 sind ausnahmsweise mal nicht mit einem Zug für die Aluminium-Industrie, sondern mit einem Containerzug bei Kamp-Bornhofen auf der rechten Rheinstrecke unterwegs.
Saturday Self Challenge
This week's challenge then is to show two things which are different, yet largely the same. For example two forks that don't match, two different types of yellow car, maybe a pair of different coloured socks from a matching set. Collage or a single image is fine. As ever new photos please.
This was one of those ideas that in my mind seemed simple but turned out to be quite difficult to pull off. I decided after taking photos of the ground pepper and the complete peppercorns in separate containers that they would look probably look better in the same one. That was when the trouble started, trying to get them not to mix. In the end I folded a small piece of aluminium foil and placed it across the middle of the wooden bowl. I carefully filled from each side and then just before I was ready to take the pictures I carefully removed the foil barrier. I did end up with a couple of stray peppercorns getting into the ground up side, but I would have caused too much of a mess attempting to remove them. I do hope it’s suitable for the challenge.
Thank you for your visit and your comments, they are greatly appreciated.
Voor rangeerwerkzaamheden op emplacement Kijfhoek zijn vier locomotieven serie 6400 toebedeeld. De 6476 tot en met 6479 zijn hier standaard gestationeerd, onder andere ten behoeve van het 'heuvelproces', waarbij goederenwagens over een heuvel gedrukt worden en op die manier gesorteerd worden. Bij afwezigheid van een van de vier valt soms een loc van 'buitenaf' in, zoals in dit geval de geel/grijze 6461. Rechts op de foto is de huidige VL-post Kijfhoek zichtbaar, die binnenkort samengevoegd wordt met die van Rotterdam en dan naast station Barendrecht een plekje krijgt.

The auditorium uses a cladding system inspired by the Newcastle-born mathematician Louis Fry Richardson whose pioneering work defined modern methods of weather forecasting. Fry Richardson’s work, which subdivided the planet into hexagonal zones, has been expressed in expanded aluminium mesh on the external elevations of the auditorium. A pattern has been created by the changing the orientation of the mesh, varying the opacity of the material.

An aluminium sculpture which is a later cast of the famous Eros figure which stands in the centre of Piccadilly Circus, London.
Designed by artist Alfred Gilbert in Art Nouveau style, the London, Eros was originally unveiled in 1893, but it was not until 1992 that this Eros came to the Art Gallery of South Australia.

07/01/2018; Enough bashing on the Amsterdam Light Festival, time for something else.
The windchill temperature was below zero last Sunday, mostly due to a very nasty northeasternly wind, but that didn't stop me from doing some shooting. Layers of clothing can do miracles. :)
