'LENA THE KILLER'

The previous post by 'Castor' set my memory board alight, wasn't there an article about 'Lena the Killer' in an older issue of Motor Cycling, and didn't I have a photo of Phil Irving with a Brough Superior record breaker?
The take-no-fools designer of the mighty Vincent twin (and diminutive Velocette LE!) isn't usually attached in folklore to George Brough's baby, but a most curious set of photos appeared last May in the fertile confines of a truck cab in Minnesota, registered to the Chantland family. Being the nosy sort, I photographed the lot front and back, and now take the opportunity to explore this seemingly forgotten and ill-documented foray of Australians riding British machinery on Austrian soil, snatching the World Land Speed Record from German hands.

Alan Bruce was well-known in Speedway circles, having set the sidecar lap record at Wembley Stadium in 1931. Australians have a dirty affinity for three-wheeled cinder sliding, then as now, and one commonly sees Vincent-powered crabs even today kicking up dirt Down Under. Bruce got the notion of a sidecar Land Speed Record while watching Paul Anderson take a national record with his Indian outfit, down Sellicks Beach, South Australia, in 1925. It took another 6 years of toil to modify an S.S.100 Brough Superior for a total speed attempt; a supercharger was added to the engine bay, and Alan Bruce hand-pounded a shapely set of aluminum alloy bodywork... which as you can see from the photos addresses the issue of drag by streamlining the rear of the outfit (including the rider's bum!). Which was the current thinking of the 1920s and early 30s, before extensive wind-tunnel testing of aircraft, cars, and lastly motorcycles, revealed that a very small frontal area was the real ticket for piercing the brick wall of wind which hits any vehicle at high speeds.

When finished, Bruce named his beast Leaping Lena, and sought a nice flat straight road to set his record. In 1931, there were only a few suitable locations for a really fast run; Hungary (Gyon and Tat), Austria (Neukirchner), the U.S. (Daytona/Ormond beach), the U.K. (Pendine or Southport beaches), France (Arpajon), and Germany (Ingolstadt). As speeds increased for record attempts, beaches became increasingly undesirable due to Neptune's fickle road-laying efforts, and attendant delays (read:money) for a perfect surface.

As all but the beach venues were public roads, the political machinations (read:money) required to arrange a few days' testing and eventual full speed runs could be daunting to a small and dedicated bunch of amateurs. Which virtually ALL those deeply speed-bitten proved to be, until National (Socialist) pride began to throw money at all sorts of sporting contests, and little swastika roundels appeared on the tails of wingless two-wheeled aircraft, and armbands on their riders. But I'm getting 5 years ahead of our story.

In 1931, Alan Bruce and Englishman Arthur Simcock took Leaping Lena to Tat in Hungary for a series of unsuccessful runs at the Motorcycle Land Speed Record, solo and sidecar. She can be seen at Simcock's side in the top photo, sans third wheel, taken on site at Tat, where various mechanical issues beset them like gremlins, and the pair headed back to England for a winter's work sorting out Issues like supercharged induction, etc. Note the copious oil leakage from the lower bodwork panels; one wonders if the lower 'tub' is in fact filled with oil!

Late April 1932 saw our familiar pair of Bruce/Simcock joined by Phil Irving, who must have provided a measure of technical expertise to sort out the troublesome animal that was Lena. Chosen venue was Neukirchner, near Vienna, and local Brough Superior agents Eddy and Kent Meyer lent a hand in any way useful - Eddy being a real champion of the marque in Europe, having won over 80 'firsts' in competitions with his Broughs. Arthur Simcock's record run without sidecar ended abruptly when his goggles were blown off at speed, followed shortly by the supercharger safety valve blowing off. Local support for Lena ended there, as a local wag slipped a steel bolt into her induction tract and shortly ruined the supercharger, cutting their effort short while they frantically sought a new venue, and spares from England.

City officials of Tat were successfully cajoled (read:money) into allowing Lena's run on short notice, and our crew high tailed it towards Hungary in their truck, which blew up and delayed their arrival. Meanwhile, Arthur Simcock trained back to England for blower parts, returning to find lousy weather (why April?), but it was decided that April 30th would be The Day, and it dawned with strong winds. Clearly, the slab-sided aluminum body of Leaping Lena wasn't lethally beset by side wind handling anomalies, and a two-way average of 124mph was finally recorded, with a best one-way speed of 135mph... really going some for a rigid-frame bicycle on an iffy concrete surface. Bruce had the scare of his life while aviating the whole outfit at speed after hitting a bump with the chair wheel, the entire plot lurching nearly off the road. While distracted and momentarily shutting off, he didn't realize he had passed the timing strips and carried on at full bore, only to hit a railroad crossing at 135mph! Man, motorcycle, and sidecar shot into the air, split the streamlining on impact, and nearly sheared off the carburettor, but hard Aussie Bruce kept the animal between the hedges, and their day was done. As he said, "Yes, it felt fast all right!"

How many times have we heard pilots of fast machines coming off after a near disasters quote something similar
"yes is felt fast all right"
It sounds so much braver then making mention of having to find a restroom

I got pointed to your blog from another blog that I was reading and I'm really liking your blog a lot.  I like the style of your writing, it really makes it easy to read and follow.  I know many blog owners out there really wonder if their stuff is being read, so I just wanted to drop an email to give you some encouragement.  You have a great blog going here, keep it up.
 
I also have a link you might want on your sidebar or links page.  The site is http://www.bikerhiway.com.  They sell a lot of apparel, safety equipment, and other stuff like that for motorcyclists.  I'm not sure if the link provides any value to you or your other visitors.  I've used them quite a  bit and they are a pretty cool company.
 
Again, the blog is great.
 
Thanks and Ride Safe

I love the crazed suicidal expression on Bruce's face in the photo below. So Glenn Curtiss would still be the fastest man on a motorcycle?

Great info Paul, as usual! Their streamlining efforts of the 1920s and 30s were actually an advancement on the minimized frontal area theory. Victor Page wrote about calculating frontal area of a bike/rider as early as 1914, it was pretty well understood then. But to minimize the Cd (coefficient of drag), they worked with their given frontal area and beat those aluminum panels into a shape that allowed good air flow off the backside of rider and bike.

I love that third photo. ;)

The more I follow your blog and read stories such as this, the more I want them in a permanent form (ie. book) that I could use for those snowy day respites needed during our icey winters. Great writing, great blog.
