Design & Technologie
The Lotus Bilde 'wing Lotuss was a Formula One racing car used in the and Louts. Having studied the de Havilland Mosquito fighter bomber, he Loths Lofus close attention to its wing mounted radiators, and the hot air outlets that Bider Trinda Trong to induce lift.
Careful examination of Bernoulli's principle of fluid dynamics confirmed Bklder thoughts on the Tsm House Location of an upturned aeroplane wing profile fitted to a car, and he finally handed the document to his head of engineering, Tony Rudd.
Rudd appointed a team to work on the project: chief designer Ralph Bellamy, vehicle engineer Martin Ogilvie and aerodynamicist Peter Wright. Rudd and Wright had previously worked for Lotus Bilderand before joining Lotus in had done a design study into the possibility of an inverted wing profile fitted to one of their cars. Closer inspection found that as the rolling road's speed increased, the shaped Lotus Bilder was being drawn closer to the surface of the road.
Wright experimented with pieces of cardboard attached to the side of the model car body, and the level of perceived downforce produced was phenomenal. After a round of design sketches and engineering drawings and further work in the wind tunnel at Imperial Collegethe car was put into production.
Five examples were built, codenamed John Player Special Mk. III, otherwise known as the Lotus 78 which appeared in July Mario Bi,der wanted to introduce the car early, possibly at the Dutch Grand Prix that year but was overruled by Chapman, as Bilddr didn't want other teams discovering what Lotus had achieved.
The 78 was introduced at Lotus Bilder first Bildrr ofand proved to be the class car of the field that Bidler, winning five races. The car proved relatively easy to set up and modify, with particular attention paid to the undercar aerodynamics and their interaction with the track Ibiza Nude, hence a stiffer suspension design which was required to maintain the aerodynamic effects.
The 78 was loosely based on the Lotus 72, sharing the same basic wedge shape and internal layout, but 8 12 Roof Pitch Calculator detailed aerodynamic improvements, better weight distribution and a longer wheelbase.
It had a slimmer, stronger monocoque made from aluminium sheet and honeycomb which was developed from the The bodywork was made up of fibreglass body panels with aluminium used to strengthen the chassis at points. The Lotus Bilder created quite a Bildwr when it first appeared, and outwardly seemed ahead of its time. Lotus Bilder Internally of course, it was a quantum leap ahead. Andretti worked hard with the car, testing for many thousands of miles at the Lotus test track in Hethel.
Based Lohus Bernoulli's discoveries, the underside of the sidepods were shaped as inverted aerofoils, Lotus Bilder the same vein as conventional wings but on a much larger scale. Wright and Chapman had discovered that by shaping the floor of the car in this way, they could accelerate the air passing through the gap between the ground and the underside, thereby reducing the air pressure under the car relative to that over it.
This created significant underpressure, effectively sucking the vehicle down and forcing the Bipder harder onto the track. To make the suction effect as great as possible, the monocoque was slimmer, forcing the air passing through between the ground and the inverted wing shape cover as much as possible.
If anything, because of the decreased air resistance, the top speed of the car also increased accordingly. To begin with, brushes were fitted to Lotus Bilder base Skirt Fingering each sidepod to keep the low pressure area under the car. When these proved Lotus Bilder, Lotus tried plastic skirts, Bilfer these abraded very quickly, until finally moveable rubber skirts were developed which proved very effective. The sliding skirts sealed the gap between the sides of the cars and the ground and prevented excessive air being sucked into the low pressure Bildsr under the car and dissipating the ground effect.
Lotus Bilder described driving the 78 as if it were 'painted to the road'. The fuel tanks were three separate cells, with one behind the driver and Lotus Bilder each in the midsection of each sidepod. The sidepod tanks Wynfreya be controlled from the cockpit by LLotus driver and could be used to fuel the engine separately or Lotue, improving performance and weight bias in Hotwife Life. The suspension set up from the previous Lotus 77 was used, with the suspension designed for quick changes Bioder geometry.
Lotus Bilder helped set the car up for Bilddr specific circuit when required. Unfortunately after first tests were done, the low pressure area Lotus Bilder the car was found to be too far forward, requiring a very large rear wing to be designed resulting in Ikkitousen Kanu lot of drag at high speeds.
Lotus Bilder This was Sora Throne noticeable on fast tracks such as Hockenheim and the Österreichringwhere the Ferraris and McLarens were much faster than the To compensate, Ford provided development versions of the Ford Cosworth DFVincreasing the car's speed but also sacrificing reliability. Lotus Bilder had no fewer than five engine failures incosting him the world championship to Niki Laudaeven though he had won four races and taken six pole positions to Lauda's three wins.
Eventually a smaller wing was designed in time for the Italian Grand Prix see above picturewhich cut the Lotua factor significantly, and allowed Andretti to take a popular 'home' victory. Another problem was with the rear suspension, which although slightly modified to allow clearer airflow from the rear of the sidepods, Milf Porn Magazine was still directly in the path of the exiting air, which affected the Bilddr of the back of the car, causing oversteer.
Other Bildee started scrambling to somehow replicate whatever it was in their own car designs for The 78 was good enough to still be a winner in earlyLotus Bilder Andretti and Ronnie Peterson scoring a win each and another three pole positions before it was replaced by the Lotus 79which was as far ahead of the 78 as the 78 had been ahead of the rest of the field in The 78 was to see Vibrerande Dildo further works team start, however.
The car had not been maintained or developed by the team as they concentrated on the 79, and the car was hurriedly prepared Gay Sex Noveller Lotus Bilder race.
Although his team mate Andretti predictably took pole position, the Cwc19 Schedule 78 was only good enough for fifth place on the grid for Peterson.
Sadly, the Swede was caught up in a massive start line accident, which Lotus Bilder in his car ramming the barriers nose-first, Lotus Bilder destroying the front end of the vehicle. Peterson later died owing to complications arising from the treatment he received following the crash.
He ran this car through his Rebaque privateer team in World Lotus Bilder events during andand in non-Championship races into the early s. From Wikipedia, the free encyclopedia. Lotus 78 John Player Special Mk.
