Thought you all might be interested in one of my endeavours. I call it the world's fastest manual wheelchair, in fact it is a streamliner hand trike, with chain driven front wheel.
Our pilot is Greg Westlake, a member of the Canadian Paralymic Hockey team. In our first outing last month at the Ford Proving Grounds Track we successfully beat the world one hour average land speed record for an arm powered vehicle at 20.757mph, or 33.406km/hr. On the week of Sept14 we will be attempting to beat the all out hand powered land speed record at Battle Mountain Nevada. Our goal is to exceed the existing record of 45km/hr by at least double. We have the machine and the pilot to do it.
The trike is an 8.5 foot long carbon fibre monocock tub and top shell, with one steering and drive wheel in the front and two wheels in the back. The bare tub weighs in at 7 pounds and is the only structural component of the trike. The rear and front wheels are attached to the tub via carbon/foam bulkhead ahead and behind the pilot. The top shell weighs under 3 pounds. All assembled with drive train and wheels it comes in at a bit more than I wanted, but still a respectable 39 pounds. We will shave some weight off of it for next year by making new wheels. These ones are carbon fibre with aluminum honey comb. I figure by refining our fabrication technique we will be able to cut a few pounds off of these.
The drive train is a modifies road bike gear set. We made a quick change jack shaft gear cluster with derailer so that we can quickly fine tune the gearing, as well create a compact drive and steering package.
