The four-man team spent three days in the wind tunnel facility at Warton in a bid to shave valbuable seconds off their time in the hope to win medal's in the 2014 Sochi Winter Olympics.
The wind tunnel, normally used to test fighter jets such as the Eurofighter Typhoon, at speeds of over 200mph was used to simulate full bobsleigh racing conditions, examining how different sled set-ups and crew positions affect wind resistance at speeds of well over 65mph (100kmph).
The testing, which was carried out alongside experts from McLaren Applied Technologies, focused on the plastic composite helmets worn by the team Joel Fearon, Bruce Tasker, Stuart Benson and driver John Jackson, to ensure they have the most efficient head protection for competitions.
Gary Anderson, performance director for the GB bobsleigh team, said the team had been 0.07 seconds off a podium finish at a previous world championships. “Our aim is to top the podium at the bigger events and we are leaving no stone unturned to maximise our performance. We are talking the narrowest of margins and the aggregate of these can be the difference between fourth place and making it onto the podium.”
