But to the extent that the prop is not rigid, the blades will bend slightly in direction opposite to the force (thrust) they produce. This bend is the change of the disk into a very shallow cone shape. I'm still skeptical of the idea that these stiff Warps cone enf to explain the variable pitch phenomenon, at least on the lower power engines. But I'm also skeptical of the idea that stalling at the tips is happening much because that means an effectively smaller prop diameter, and it is the big prop diameter (high aspect ratio) that is so generally useful in producing high lift (think gliders). I'm starting to think neither coning or tip stalling is responsible for the Warp's performance on small engines, and it is simply that they are a great, low drag, very effective airfoil. --- Kirk Smith wrote: > --> Kolb-List message posted by: "Kirk Smith" > > " Most props will cone unless it is an over designed propeller.

A tractor has some possibilty of picking up a pebble, but a pusher has the added possibilty of whacking anything coming off the airplane in front of it. Especially open cockpit pushers, the pilot ought to make darn sure everything in his cockpit and pockets are going to stay put during the flight. Also, pushers have the risk of pebbles coming up from the tires getting into the prop. This esp true if the prop is close to the ground as in the Ultrastar. I think these are manageable risk areas, but they are added factors, and a more bullet proof prop would be good insurance IMO. > > Could you comment more as a performance comparison between the IVO > (number > of blade and length) and the Powerfin (type of blades, number, and > length). > jerb I don't know enf to comment specifically. Generally tho, thrust and efficiency comes from greater prop diameter (think about moving a small disk or column of air with a smaller diameter 3 blade, compared to moving a bigger column of air with a larger 2 blade). It is also true that a prop being extremely flexible, or flexible in the "wrong directions" allows for it to dump its load instead of making thrust. I think (guessing), that the IVO excels in its smoothness and is weak in thrust -- compared to other props -- because it is a relatively flexible plastic. The Powerfin is foam core, composite shell if I recall, and is pretty good at absorbing vibration (like wood) without the expense of high flex and changing its aerodynamic qualities. Warps are solid composite --heavier, near bullet-proof, and very rigid. -Ben > snip.. > >Wood (Culver or Tennessee?): almost as good as the Warp in > >performance, but the added risk of wood props as a pusher. > snip... > > > > _-> > > > > > > ===== http://mae.ucdavis.edu/~ransom __________________________________ ________________________________ Message 6 _____________________________________ Time: 10:17:17 AM PST US From: Eugene Zimmerman Subject: Kolb-List: 2 Honda engines on Ebay --> Kolb-List message posted by: Eugene Zimmerman Here is a four stroke for you to experiment with. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=6755&item=2448438777 ________________________________ Message 7 _____________________________________ Time: 10:22:24 AM PST US From: jerb Subject: Re: Kolb-List: Propellor --> Kolb-List message posted by: jerb Richard, Thanks for clearing that up.

What fun. It is amazing how easy it is to 2nd guess yourself with only maps and no GPS. I know what santa needs to bring me now. I wanted to run some speeds and rpms by the group to see how they compare: solo ~215lbs. I cruised my first leg at 63-65mph indicated at about 5100rpm. I thought the lower rpm would save some fuel even though it would take longer to get there. I was wrong. First and second leg were both right over 50 miles (minimal wind). The second leg I cruised at 5800rpm showing 85mph indicated. I burned less gas and arrived about 15 minutes faster. I did notice at about 88-90 (slight dive at 5800rpm) indicated my wing tips would shutter a little, getting very noticeable over 90. I know the VNE is 100, but considering the shutter I don't think I would want to go over 90. Anyway... It was a beautiful Colorado morning. Meadowlake to Frontrage to Limon to Colorado Springs East back to Meadowlake for a total of 152 miles. I have done some dual X-Country in a piper archer2.. cruising at about 110Kts. It sure was more rewarding to cruise around slower and lower in my mk3... I have a new appreciation for those kolbers that fly around the country. It must be a hell of a thrill to tour in a kolb.

It was a beautiful Aaron I am surprised the 618 uses as much gas at 5100 as it does at 5800, are you sure it wasn't the wind? My 690L burns less than 3.3 gph at 5100, but seems like it gets up around 4.7gph at 5800. These two engines are pretty different so I suppose I'm comparing apples and oranges.

They are not however. one measures 61 3/4 (the left) And I have never measured the right hand, although it was presented as a 60 when I bought it new. I had the left on a 2,5 belt drive on my fly...and when I lost one a them polychain belts at 32 hours...I switched it to a 2.65 gearbox and a right hand Ivo. So I really cant make any good comparisons on how they preform...being at 2 different ratios. BUT...I can tell you that the right hand prop does look different than the left. In the wide part of the airfoil..there is more there than on the left hand prop. It is wider I believe ..although I have never measured the right hand prop...but it looks wider and looks like there is more pitch in that spot from eyeballin it. I also have had a 3 blade 60 inch Sport prop on it...real pretty ...that black carbon fiber. All I really can say is it was a tad harder for the Cuyuna to turn. even being lighter than the ivos...the rpms didnt come up as quick...but I wont say any more because I just didnt have it on there long enough to give it a good workout. I thought I had it pitched about the same, as I measured the ivo with a protractor and set the sport accordingly...then checked the rpms and they were about right. But as I said..didnt run it long enough to really get to know it.
