Running a Mile in Very New Shoes

The Lola-Drayson LeMans Prototype (LMP) did not make it to this year’s LeMans race at the Sarthe track, but did make its racing debut at another prestigious motorsports event – the Goodwood Festival of Speed Hill Climb in England.  Nowhere near as long or treacherous as America’s Pikes Peak event, the race is a good test of acceleration, handling and sheer power, which the car displayed with great style. http://www.youtube.com/watch?v=sd-vAq4IDRA Lord Paul Drayson, a former science advisor to the Crown, drove the B12/69EV, a car crammed with new technologies, many of which have been reported on in this blog, and which have potential applications in aircraft.  He also set a new record for electric cars in the climb, doing a timed run of 53.91 seconds and placing 11th overall in the July 1 run.  Goodwood’s hill climb is only 1.86 kilometers (1.16 miles) with a mere 9 turns, and the fastest official time up the slope was the 1999 McLaren …

A Not Totally New Idea After All

Delos Aerospace patented an electric landing gear system as early as 2007, according to their web site.  Steven Sullivan, an alert blog reader, provided the following lead for your editor. Delos says, “This revolutionary technology is a total systems integration of a fully electric landing gear and maneuvering system wherein axial flux disk motor/generators replace the old friction disk technology providing increased braking and maneuvering capability to the aircraft wherein there are many engineering benefits to eliminating the heat generated within friction based braking systems.” Use of these brakes could reduce takeoff distances and increase range by reducing fuel weight otherwise required for takeoff and cruise.  Power would come from an auxiliary power unit (APU), currently part of most large jet aircraft, that would generate electricity to allow the wheels to “drive” the airplane from its parking space to the runway for takeoff, or on landing to take the airplane down the taxiway to its concourse gate.  These maneuvers alone …

Formula 1 Cars and Mazda Recover Waste Energy

David Bettencourt, a criminal defense attorney and aviation lawyer in Hawaii, is a follower of Formula 1 racing and energy-efficient systems.  He filed a brief with your editor on the following. Kinetic Energy Recovery Systems (KERS) were a relatively new thing in Formula 1 racing in 2009, had significant development problems and were banned in 2010.   Reinstated in 2011, the systems recover the kinetic energy present in the waste heat created by the brakes and exhausts. The energy is then stored in a battery or a light, extremely high-speed flywheel, converted into power and can then deliver a maximum of 60 kilowatts (80 horsepower), which can be called upon by the driver to boost acceleration for up to 6.6 seconds per lap. Williams is a major Formula 1 constructor and developer.  Sam Michael, Williams technical director, explains.  “The rules have changed since KERS was last used in F1.  Re-fuelling is no longer permitted, so the packaging is different now. We …

The Battery Pack Builder with the Ceramic Wedding Ring

The Killacycle Racing Team is led by two people, Bill Dube’, designer, builder, and driver of the world’s fastest electric motorcycle, and his wife, Eva Hakansson, crew chief and battery builder for the high-velocity two-wheeler.  Eva’s talk at the fourth Annual Electric Aircraft Symposium in Rohnert Park, California caused several stirs in the audience, and hinted at where battery technology might go in the future. Wanting to free electric vehicles from their “boring and slow” image, Eva seeks to make them “sexy and fast.” Pictures of her and Bill’s wedding, in which the bride wore traditional Swedish wedding garb and entered on a motorcycle, the ceremony took place in a motorcycle trailer, and for which both bride and groom wore ceramic wedding rings (necessary to prevent dead shorts while building battery packs and riding the 500 horsepower machine) show the domestic and the purpose-driven lives of both. Campaigning a high-performance vehicle of any kind, let alone a one-of-a-kind creation such …
