fatmal Posted October 11, 2012 Share Posted October 11, 2012 U.S. Airforce looks to save fuel with formation flying of cargo aircraft http://www.networkworld.com/community/blog/air-force-lab-test-out-%E2%80%9Caircraft-surfing%E2%80%9D-technique-save-fuel An FA18 can reduce fuel burn by 29%, by flying in the vortex of a DC8 - approx 200ft separation.\\Mal Link to comment Share on other sites More sharing options...
Sapphire Posted October 12, 2012 Share Posted October 12, 2012 If you look back and see a dozen a/c following, then you will be the one paying the biggest bill. Link to comment Share on other sites More sharing options...
boingk Posted October 12, 2012 Share Posted October 12, 2012 Same principle is being applied to cars, with tehcnology being used to adapt an autonomous 'road train' comprised of separate cars all going to a similar destination. Very interesting stuff. Of course, cyclists have been doing it for decades. - boingk Link to comment Share on other sites More sharing options...

Guest Howard Hughes Posted October 12, 2012 Share Posted October 12, 2012 A lot do that already-called tailgating I think some of the tailgaters are too close, to have the desired effect! Link to comment Share on other sites More sharing options...
Sapphire Posted October 12, 2012 Share Posted October 12, 2012 Especially if you slam on your brakes infront of them. After that they can follow you with their engine off. Link to comment Share on other sites More sharing options...
turboplanner Posted October 12, 2012 Share Posted October 12, 2012 That's the principle NASCAR racing is based on. They started as moonshine tankers to cart from the stills to the City, and often ran with Revenuers stuck to their tails until one of the other ran off the road.

Guest Howard Hughes Posted October 12, 2012 Share Posted October 12, 2012 Not really racing then is it? More like a really fast Mardi Gras, or Moomba parade! Link to comment Share on other sites More sharing options...

turboplanner Posted October 12, 2012 Share Posted October 12, 2012 Interesting - what would be the average lap speed? Link to comment Share on other sites More sharing options...
turboplanner Posted October 12, 2012 Share Posted October 12, 2012 The Daytona lap record was set in 1987 by Bill Elliott in a Ford at 210.364 mph/338.548 km/hr/182 kts - average speed. The Daytona 500 mile record was set in 1980 by Buddy Baker at 177.6 mph/285.94 km/hr/154 kts. - average speed over 500 miles Link to comment Share on other sites More sharing options...
winsor68 Posted October 12, 2012 Share Posted October 12, 2012 The Reno lap record is over 500mph... Link to comment Share on other sites More sharing options...
turboplanner Posted October 12, 2012 Share Posted October 12, 2012 Wikipedia is only saying they REACH those speeds; they would lose a lot in the turns, so it would be interesting to see the average lap speed. Just got a comparison for Formula 1, with the all time record being set at the 1971 Italian GP at 150.754 mph/242.6 km/hr Fastest speed recorded in F1 was a McLaren in 1998 at 240.19 mph/386.7 km/hr/208 kts Top Fuel Drag Racing trap speed record is 333 mph/536 km/hr/288 kts Link to comment Share on other sites More sharing options...
winsor68 Posted October 13, 2012 Share Posted October 13, 2012 The L-39 speed record as I read it is over 500mph... of course when we think of Reno we think of the Unlimited Racers. RareBear is quoted as having attained 500+ on the straights for but not for a lap. Link to comment Share on other sites More sharing options...
corvairkr Posted October 13, 2012 Share Posted October 13, 2012 Here we go gents, Strega won Reno this year with an average speed of 477mph thats not to shabby. http://reports.airrace.org/2012/2012.Unlimited.BreitlingGold.Results.Report.html jason 1 Link to comment Share on other sites More sharing options...
pylon500 Posted October 14, 2012 Share Posted October 14, 2012 Tailgating, or being sucked along by drag, is not going to be a very effective way of saving fuel. However, if you can reduce the amount of power used to generate the lift (which induces drag) by flying in a continual updraft created by an aircraft in front of you, then you can save some fuel. Like I said "Geese, Swans, Ducks etc have been doing it for centuries........" Arthur. 1 Link to comment Share on other sites More sharing options...
