If you just want to make a VW or Corvair windmill, just lower the compression ratio to the same ridiculously low level that aircraft engines are, and you too will have a windmilling engine. From the Corvair's 9:1 down to the aircraft engines' 7:1, you'd probably lose about 10% of the power, but if that's all it would take to make you happy with the Corvair or VW, it might be worth it to you. Lowering the compression ratio is as easy as buying twenty bucks worth of barrel shims or head gaskets, and doing a proper "cc'ing" of the chambers, which is something every engine builder should do anyway.

The Corvair is already a good motor, so de-rating it by 10% will make it bullet proof. Your comment is encouraging and I would be delighted if this can work out - this is however how I see it. The tendency (ability) to wind-mill at cruising speeds is influenced by how much resistance the engine presents to being turned over (CR), as well as the force that is trying to turn it - and that is very much a function of propeller diameter and blade area. Smaller props have less leverage (and inertia). To achieve fair grunt out of any motor, we need to let it get a respectable way up the power curve. In the case of the Corvair I suspect that this will be well over 3000 rpm, restricting the propeller diameters to something like 65" on a direct drive. (not that there is room for much more). My instinct has always been that - by the time you drop the CR to the point that 80mph (approach) will keep a 65" prop turning a 3L engine (approx)- the CR will be such that maybe 30% of the potential power is lost. If the CR reduction required to allow a typical KR prop to wind-mill is such that the power loss is 10% /12%) - this would change things for me. Take care Steve I visited your engine CC'ing site - excellent piece of work, written in a way that that makes me want to do one. ------------------------------ Date: Mon, 23 Feb 2004 11:45:10 EST From: Veeduber@aol.com To: krnet@mylist.net Subject: Re: KR> Windmilling Message-ID: <76.3823c6bf.2d6b8816@aol.com> Content-Type: text/plain; charset="US-ASCII" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Precedence: list Message: 8 To All: Want to make your veedub air-startable?

There seems to be a fear out there of ground loops. Perhaps the following will make my point. A friend had a Stits Playboy. A low wing 2 seater with a Lycoming 0290 G engine and NO BREAKS. I saw him land long on a short runway which terminated in a dirt field beyond which was a low ditch. The ditch was deep enough to be a real problem. He ran off the end of the runway and ground looped.There was a great cloud of dust, he went around 2 or 3 times and just taxied back. I asked him what had happened. His reply was that he could not stop so he stomped on the left rudder and kept the stick back. This turned out to be his standard emergency stopping method. The Playboy had a wide landing geer. (a tail dragger). Eventually he put breaks on it. I flew it a lot. One day I was flying it in the spring on a slushy runway, It persisted in turning left even with full right rudder.( It had developed a flat tire on the left.) Rather than run off the left side of the runway into a landing light , I followed his example. Stick back , full left rudder. It was quite an experience. No damage, no problem . I would not like to try that in any high winged plane. So if you ever get into a ground loop in your KR, KEEP THE STICK BACK, (and good luck) Harold Woods Orillia,ON Canada. haroldwoods@rogers.com --- Outgoing mail is certified Virus Free.

You can make a VW or Corvair turn a prop slowly too. William Wynne's Pietpol ran a Corvair at about 3000 rpm WOT and he claims an output of about 90 hp, and turned a 68" Warp Drive prop on it. See http://www.flycorvair.com/corvair.html#Engine%20Specs for more details.

Same scenario here except I also had the Director of the DCA (CAA) snoozing in the back of my Cherokee 6. When that 9 liter, 300 hp mill quit delivering, there was no doubt in anyone's mind.
