Ideal time to make progress on the project. Head scratching time!? I started taking a look at the Soobs Turbo intended for my KR. A tight fit is putting it lightly. I have a few questions. 1 Can the guys that have fitted the EA81T into the KR give me an idea of the engine mount frame. I would like to us the existing mounting points at the bottom of the engine but I am concerned about the angle of the bottom member from the existing engine mount to the fire wall (it goes though the exhaust) 2 Where is the Turbo repositioned? The engine that I have has the the turbo fitted between #4 cylinder and the gearbox. Clearly this must be moved 3 How far is it from the fire wall to the pulleys on the engine (DD on the flywheel side) and where is the radiator fitted. I had a look at the pic's of Roger Enns & Rob Brobergs Dragonfly for some ideas but I think the Dragon fly has a deeper firewall than the KR2. Are there any other pics of the EA81T DD installation on the Internet?

You have to consider a lot of factors like the Reynolds Number, size, aspect ratio, end effects, wall effects, etc, etc. Scaling is not a direct function of the size, since some things change in a linear manner, some by the square of a parameter, and some by the cube of a parameter. For example, surface area increases as a square of the characteristic dimension, and the corresponding volume increases by the cube of the characteristic dimension. The reason to have full sized tunnels is to get the real, unbiased truth about the configuration. As far as I know, all of the really large wind tunnels have been shut down since they are so expensive to operate. All work is now done with Computational Fluid Dynamics, which is an electronic wind tunnel. - -- Don Reid mailto:donreid@erols.com http://www.erols.com/donreid/kr_page.htm ------------------------------ Date: Fri, 02 Jan 1998 06:37:04 PST From: "Oscar Zuniga" Subject: KR: Low fuel indicator FWIW- Here's an item from the sooblist, where a guy took a "low fuel" sensor and idiot light from the tank of a car (Subaru) and tested it in both water and fuel: > If you place one of these cheap automobile low fuel senders at >bottom of sump, it will glow "water in fuel tank" when water is >present.

Wind tunnel tests showed rigging wires had very much more drag than their cross-sectional area - compared with a thick rod - indicated, if a simple scaling rule was applied. That's one reason why most any graph in this field is non-dimensional - the author knows you will have to scale his results appropriately - and the units are meant to help you (ha!) There are seven or eight scaling rules which depend on viscosity, a principal dimension compared with airspeed, air density and so on. Reynolds is one that comes immediately to mind. Designers have been known to trade speed for density - when they 'fly' models in a swim-pool.... brian whatcott Altus OK ------------------------------ Date: Fri, 2 Jan 1998 12:32:42 EST From: LDeckert Subject: Re: KR: EA81T In a message dated 98-01-02 01:54:08 EST, you write: << Snip Are there any other pics of the EA81T DD installation on the Internet?

The 2-rotor version weighs 135 lbs and delivers 150 hp. This engine turns 8 or 10 thousand rpm so it would (obviously) require a PSRU. Moller does not offer this engine specifically for aviation but there are several companies planning to sell engines converted for aircraft use. It seems like the 1-rotor version would be perfect for a KR, but they do not say how much it weighs, though a little more than half of 135 lbs seems like a good guess. This is really interesting technology using exotic lubrication and cooling methods. I would recommend having a look.

It's planning time, A couple of weeks ago someone floated the idea that we should all stay at the same motel at Sun & Fun. It's time to get the ball rolling, somewhat like what the video did for my building motivation. I have stayed at the Budgetel Inn, Tampa Fairgrounds. This motel is on the Lakeland side of Tampa and is within about 20 minutes as I remember, it's not much of a drive. I called tonight and checked on the availability of rooms and was told they have as many rooms as we would need. If we book under the KR name we would all get a group discount. Considering the price of food at Sun & Fun, any savings is a good deal. This of course would have to be run through the manager but I was told it would be no problem. If anyone has a better place to stay, speak up or comment of this location and if you would be interested and I'll call this guy back and shake his tree for rates.

I am planning on purchasing a KR2S kit in about a month. It is obvious from the emails I have read so far that their is a lot knowledge in this group that I would like to take advantage of. My biggest concern right now is what engine to choose. Reliability while maximizing cruise speeds is my primary objective. I am also contemplating installing a constant speed prop.

The other pilot was Ken Mintz in his Vari Eze (N86KM). I noted the following: At 5000' MSL OAT was 50 degrees F. IAS was 162 MPH, Manifold preasure = 28 inches Hg. RPM = 3570. Gross wt = about 1040 LBS. I had 18 gal of fuel and a 236 LBS pilot. We are going to double check our numbers against a GPS when the wind dies down out here. I will let you know what I get on the next go round with several other speeds as well. The climb rate out of Boulder city was only about 400 ft/min with full fuel.

The vented cap may not be enough, unless the vent is done like a Cub, etc. cap with a forward facing tube, at least 1/4" diameter. If you use a vent line, it needs to enter the tank at the rear-most wall, travel along the top surface of the tank, and have its opening near the front surface of the tank. This ensures that fuel will not leak out under any reasonable pitch angle. I ran my vent line down and it exits at the landing gear fairing. The end faces forward so it will tend to pressurize with the air flow. - -- Don Reid mailto:donreid@erols.com http://www.erols.com/donreid/kr_page.htm ------------------------------ Date: Sat, 03 Jan 1998 08:24:42 -0500 From: Donald Reid Subject: Re: KR: props Douglas Dorfmeier wrote: > My biggest concern right now is what engine to > choose.

Engines are like opinions, everybody has a favorite that will offend someone else. My choice was is an O-200. Just remember that most constant speed props are heavy. A flexible, almost constant speed prop may be a compromise. - -- Don Reid mailto:donreid@erols.com http://www.erols.com/donreid/kr_page.htm ------------------------------ Date: Sat, 3 Jan 1998 09:40:22 -0500 From: "Ron Brown" Subject: KR: Gluing Foam As a new member to the KRNET and someone who has just started working with foam and fiberglass.

By the time you get ready to fly the rear drive setup may be ready and then your choice of props are much better. Marvin McCoy Seattle, WA.

A big part of going fast has nothing to do with the engine. It involves building a LIGHT airplane with minimal DRAG. I suspect that a review of techniques to keep the plane light might help. I will provide some thoughts from a non-expert. First of all, very part you build must be done with the thought of staying light. It does NOT mean reducing wood sizes or using smaller bolts than called for. Those things could result in catastrophic failure. In means cleaning up excess glue from joints. For some, it means foregoing a starter and electrical system. It might mean using light-weight electronics and 2 in 1 or 4 in 1 type gauges. With the composite parts, you should make sure everything is smooth BEFORE fiberglassing. if you have a small bump in the wing foam, that will show up as a bump in the fiberglass...and you will have to add unnecessary filler around it to make a smooth surface. Take lots of time here to save time filling. It also means look at the aerodynamics of the KR. I would strongly suggest that you look at Mark Langford's web site for his OPINION section. There are several things there that you might consider...the possibly excessive wing incidence, washout (?) and horizontal surface incidence. I am not an aero engineer so I cannot say if they are correct, but my BUBBA analysis is that they seem reasonable. Also consider contributing to the NLF airfoil test effort. That may have the potential for speed increase (otherwise, why bother). Someone mentioned the VW read drive mod. That with the other things mentioned above should make for a fast airplane on reasonable power. A constant speed prop is likely not an option on many of the engines in KRs. If anything, a turbo might make more sense. But if you are trying to use power to muscle a plane that is 100 pounds overweight, then you made mistakes in building the plane. Troy Petteway has a fast plane (no electric system) as do others. The bottom line is that you can have an incredibly fast, economical airplane if you do your homework up front and build it light. And take advantage of well thought out modifications. ------------------------------ End of krnet-l-digest V2 #1 ***************************
