Add More Lightness

It was Lotus' Colin Chapman who famously coined this phrase, but Porsche's engineers turned the concept into a science and, during the 1960s, few manufacturers could rival Porsche's knowledge of lightweight metals, alloys and glass-reinforced plastics. Like its predecessors, the 909 Bergspyder used an aluminium spaceframe chassis and exotic titanium was then used for various suspension components, including the four coil springs. The engineers even experimented with alloy steering arms, but...

Art Us Physics

'What has always fascinated me more than anything else about racecar engineering, in its broadest concepts, is the combination of art - in terms of the ideas - and the test of those ideas, against well established physical principles. Having a great idea in itself is no use if it doesn't stand up to the harsh test of the physics. And, of course, we have to adapt ideas to any changes in regulations and sometimes, as in the case of a new tyre manufacturer, we don't always know quite what we've...

Billet Button Pistons

US-BASED SPECIALIST PISTON supplier, Diamond, is now offering a new inboard billet piston with buttons instead of gudgeon pin clips, designed specifically for racers who regularly replace pistons in a hurry and who want the benefits of a modern inboard piston design. Compared with the removal of the secure yet unwieldy spiral locks or round wire locks found on many pistons, changing buttons is remarkably rapid. In addition, on pistons where the pin bores intercept the oil control ring groove,...

Declaring The Variables

If we look a bit closer at how a typical advanced mathematics channel or program would be built up, it is very similar to popular programming languages. We start by declaring the variable we will be calculating, followed by a list of data channels we wish to use in the calculation. This could be anything the data system is currently logging. Next we need to declare all the constants we wish to use. Normally, these are handled separately and, in this example, the advanced mathematics package in...

Faster Processing

Fundamentally, there are only two ways to speed up a computer. You can increase the system clock frequency by improvements in silicon technology, thereby processing information faster, or you can attempt to do more processing in each cycle, effectively doing work in parallel. Throughout the late 1970s and up to around 1985, there was about a 30 per cent performance gain every year through improvements in semi-conductor technology alone. But from 1985 to the turn of the century, the computer...

The fierce rivalry between Porsche and Ferrari has its roots in the 1960s. Even though the two companies were founded at about the same time and competed in many of the same races during the 1950s, up uintil then they rarely crossed swords. But when Porsches started to vie for outright victories, the two legendary manufacturers became direct competitors. The epic fight between the Ferrari 512s and Porsche 917s in the 1970 and '71 editions of the 24 Hours of Le Mans is well documented. These...

No Uphill Battle

Two cars were completed but they were not ready in time for the start of the '68 season. In the end, this proved inconsequential as Gerhard Mitter more than held his own in the rebuilt 910 8s, and the Ferrari threat proved hollow as nothing was seen or heard of the flat 12-engined special, at least not in 1968. Although Mitter dominated the opening rounds of the championship, it was far from 66 the entire wiring loam was made in silver a happy campaign for Porsche, as Mitter's team mate, Rolf...

Uni-processor parallelism is the simplest form of parallel computing and is combined with the benefits of RISC (Reduced Instruction Set Computing) processor architecture developed during the late 1980s to produce increased performance. As all the parallelism is achieved within the chip, the system design is relatively simple, and the parallelism is achieved by the application software compilers. Modern, high performance, desktop workstations utilise Multi-processor parallelism was the next...

Some years ago, Patrick Head explained to me how to make boats from concrete, but I never envisaged he and Williams would ever embark on a similarly curious public flotation exercise for the entire team.

Both the Lotus T128 and the Force India VJM04 (shown) have re-visited the 'blade' concept for 2011 'The main target was to clear all the area to the rear lower wing because it is a performance differentiator now,' explains Williams' technical director, Sam Michael. 'You've got to have the underside of the rear lower wing completely free, so we took the decision to lift the top wishbone and the track rod and go to a z-bone layout, which was commonly used in the early '90s to get that all above...

The Cars For 2011

When not arguing with Ford over model designations, Ferrari is developing a push rod rear end with a damper package reportedly linked front to rear lower wing, whereas a pull rod is completely out of the rear lower wing. That was an easy decision to make.' Not everyone agrees, though. Ferrari, for example, has adopted suggest that one of the issues with this layout is that for the mechanics to adjust the dampers they now have to remove the floor of the car. 'We were working with different set...

Tyres

Aside from the new aerodynamic regulations, the biggest single change for the 2011 season is the arrival of Pirelli as the single tyre supplier. To ease the Italian firm into its role, the weight distribution for all cars has been fixed - no less than 291 kg on the front axle and 342kg on the rear. With the overall weight limit increased to 640kg, it gives teams a window of 7kg to play with.
