Electric blanket (motorsport)

from Wikipedia, the free encyclopedia
Tires with electric blankets and power pack for their power supply

Electric blankets (English tire warmers ) are used in motorsport to heat the tires of a vehicle to the required operating temperature before they are used. The blankets bring the tires to a temperature of around 80 ° Celsius, usually a little below the ideal operating temperature. Tires preheated by electric blankets achieve more grip in the first corner , so the vehicle achieves significantly higher cornering speeds and, as a result, faster lap times.

formula 1

In Formula 1, electric blankets were used for the first time at the European Grand Prix in 1985 by the Lotus team and were soon standard.

In the course of the reintroduction of slicks in the 2009 Formula 1 season , the FIA planned to ban electric blankets. However, this was discarded in June 2008 due to safety concerns.

In the summer of 2012 a ban on electric blankets was discussed again, this time also for cost reasons. McLaren boss Martin Whitmarsh put the cost of transporting and operating the electric blankets and the power generators required to be 300,000  pounds a year (approx. 370,000 euros). Robert Fernley , Deputy Team Principal of Force India , also stated that without electric blankets, about three fewer mechanics would be needed per team. In addition to several drivers, tire manufacturer Pirelli also rejected a ban for the 2013 season because the tires currently in use were not developed for use without electric blankets.

Alternatives

Mounted tires are brought up to temperature by zigzag driving as well as strong acceleration and braking maneuvers, for example when the tire temperature drops due to the use of a safety car .

One way to warm up tires without electric blankets is to use an "oven". For example, the RML Group uses an infrared heating system in its sports car operations.

Another alternative are walking scooters, on which you let the driven wheels of the vehicle run with your own engine power in the paddock.
