The fact that it easily burns is no surprise. Rotax made an engineering mistake with Evans and is backing off. PFA is making the situation more confusing with a totally mindless directive. For safety, experimental a/c builders need to understand the facts, rationales, and theorys, and to know which is which. Unlike the the antique powerplants in certificated a/c, Rotax engines have a significantly different metallurgy - they are made of aluminum alloy. Fact. This alloy anneals just below 300F. That is to say it softens and the cylinder heads will begin to warp with temperatures exceeding 275F for a length of time. Fact, see Line maint manual for temp-time tolerance curve. This temperature limit is more than 100F below routine lycosaurus CHT. Exceeding the time-temp limits buys you a tear down and Rockwell hardness testing of heads. Liquid coolant is required to keep Rotax CHTs in the required range. The coolant must provide an efficient path to dump combustion and compression heat to preserve the temper of the aluminum. Evans is far less efficient at heat transfer then water-based coolant.Fact. The "value" of Evans is its higher vapor pressure. Why? As fluids approach their boiling point they start to nucleate small bubbles (look at a pot of near-boiling water). These bubbles insulate the walls of the coolant path from efficient heat transfer from the metal to the liquid. Evans will not form as many of these bubbles at operating temperature as standard coolant. It will nontheless let heads rise closer to the annealing temp because it can't carry away the heat as fast even without the bubbles. A new solution to continue using water based coolant is to change the radiator cap to 1.2 atm from 0.9. This will keep the vapor bubbles from forming in the old coolant and lead to altogether better heat sinking the cylinder heads.(Theory) There is a new SB for kit manufacturers to measure coolant temperature or to measure the extent of the gradient between the standard CHT measurement point on the outside of the head and the coolant outflow point. The temperature of the coolant exiting the head, going to the radiator is always hotter and more closely related to the max temp inside the head than the CHT sensor. The coolant temp must not exceed 275F and if the gradient to the true internal temp is not known, then a worst case assumption leads to the new max (old style) CHT of 248F As for the flammability and the PFA, every other fluid forward of the firewall is flammable. One more adds no significant added risk. Stemme had a poorly designed coolant/exhaust system which lead to melting of coolant lines. This, I submit was the problem, not the flammability of the coolant! It could have just as easily been a gas or oil line. Temperature shield hoses and keep the engine aluminum cool! Check out the new intrinsically heat-shielded fuel line hoses in the 900 series now shipping. Nice clean new design to deliver fuel to mechanical pump and thence to carbs with new crimp fittings, a double banjo line splitter, etc. Ira N224XS Fresh from Dean Vogel's Rotax Engine course. ________________________________ Message 5 _____________________________________ Time: 09:09:12 AM PST US From: "Mike Parkin" Subject: Re: Europa-List: Re Coolant Coice I have just drained the Evans stuff out of my 914 - putting it in the engine in the first place was not my best ever decision.

Phase change from liquid to vapor absorbs several hundred times more heat than just raising the coolant temperature just another degree, and helps convection. This was clearly established by NACA researchers during the '40s. See Contrails http://contrails.free.fr/engine_liquide_refroid.php (only in French at the moment) Scroll down to the NACA reports. Also some basic info at : http://www.tpub.com/content/doe/h1012v2/css/h1012v2_62.htm Please note that we are speaking of nucleate boiling, and not of the "boiling crisis", which is the transition from nucleate to "film boiling". It is film boiling which tends to isolate the hot walls from the coolant. Best regards, Gilles http://contrails.free.fr ________________________________ Message 7 _____________________________________ Time: 10:50:51 AM PST US Subject: Re: Europa-List: Re Coolant Coice From: Hello Ira The info provided about flammable liquids was not a full discussion on the Pros and Cons of Evans, but was results about the flammability which I wanted to see and feel actual results for myself before I went flying with it in my cooling system. The results were just about what I expected. I added a test to see if 100LL in fact does ignite as easily as Mobil 1 when put on a hot muffler (it does not, Mobile 1 ignites a lot easier). There are Pros and Cons about Evans. I spent several days in contact with folk at Evans when Rotax first came out with recommendation. I have posted results and my conclusion in the past, but will restate: The folk at Evans were a bit shocked that Rotax made such a quick and bold jump with so little testing in their opinion It is true that Evans can run with a Zero pressure coolant pressure cap, but that is when the system design has cap located on the vacuum side of the water pump. The Rotax 9xx has the pressure cap on the pressure side of the water pump. You should not run a Rotax 9xx with a zero pressure cap. On my 914 install, I will run Evans with a .9 bar cap. The ability of Evans to transfer heat is not as good as water, or quite as good as a 50/50 mix of water and Ethylene Glycol. Evans on most of their applications recommend increasing flow rate of water pump or increasing radiators ability to dump heat to compensate for this. I don't know of a high flow Rotax water pump for use with Evans, but may be a good idea?? Evans also knows that Evans is more viscous and the radiator should not be too restricting, or it needs to be replaced with one less restrictive, I have the info of core requirements if anyone needs, but the Stock Europa Radiator seemed OK when I measured it. Evans will run a bit hotter than a 50/50 mix due to a poorer ability to carry away heat (Perhaps 10 degrees F, what I have read anyway about Europa Monowheels). I am willing to accept this downside. I am installing a Rotax cooling air baffle that I think will just bout negate the slight higher temp Evans will run over a 50/50 mix. On a 914 with intercooler, and a monowheel to restrict cooling flow on the ground, boil overs on ground and in the air are not a welcome occurrence. In addition when you are making some BTUs at altitude (an intercooled 914 can more easily do than normal aspirated), remember that the pressure cap for the cooling system is not altitude compensating, thus at altitude you will have less pressure in the system than at sea level, and less air to cool things. (Side note, this lesser pressure at altitude and higher oil temperature can cause oil tank to not condense foaming oil and a very undesirable oil pressure drop can occur, same goes for 912 or 912S). Even though you could have an overall acceptable coolant temp and cylinder head temp there can be pockets of boiling coolant that have very little ability to carry away heat and can cause hot spots a gauge will not reveal. Evans has a much higher boiling point, and even if you did get it to boil, it still will carry away a significant amount of heat (Think it is 50% ??) of what it is capable of when not boiling. Evans does not have to be changed, and will not hurt aluminium. Use of Silicone coolant and radiator hoses, should negate having to replace every 5 years, not a trivial job. Should a leak occur where pressure was reduced, Evans would conduct at a lower pressure better than a boiling 50/50 mix. If you developed a coolant leak, landed and repaired and could not find Evans, You could mix up to about half with Ethylene Glycol to get you home, but then should flush and replace with Evans 100% (according to Evans Tech.). Evans about a year ago would test your coolant (for free) to make sure it is still up to snuff (CT office). I fully agree that keeping the heads of a 9xx cool so as not soften them is a worthy effort. If I find that there are conditions that temporary put motor hotter than I care for, a water spray onto radiator could help with that, no matter Evans or 50/50. I am also going to try and optimize cooling intake and exhaust for radiator, intake no larger than needs to be, exhaust adjustable cowl flap (Gilles has great info on cooling dynamics). If I see that things are not quite acceptable, an easy thing to try a 50/50 mix (I also have a 1.2 bar cap). Another subject, but keeping the oil hot enough, and warming it up before you make some BTUs is a worthy effort. Especial desirable when performing a restart after soaring. I am installing a Mocal oil thermostat with -8 fittings. It always allows a path to and from oil cooler, so if it failed with valve opened or closed, you would never starve for oil (like some others I looked at). What the Mocal does, is allow a easier bypass path internal so instead of all the oil going through the cooler, for the most part takes the easy path. there is however some oil going through the cooler at all times. I will plumb my oil system with Aeroquip 498 and 598 (same hose, black or blue) and use mostly Aeroquip steel crimp on fittings. Will use McMaster 90 degree stainless large radius thin wall barbed tube fitting for bend needed. The 498 and 598 have same ID as FC332, has a slight tighter bend radius ability without kinking (slight larger OD, not much), and I like the crimp on steel fittings better than the brass or aluminium push on barb fittings. The ID is very large for a -8 hose, and is good for 300F on inside and 250F with air.

However, the original Europa installation was not designed to operate with Evans. With G-JULZ, Rotax 914 monowheel, it is quite obvious that the cooling system is working close to its maximum capacity during a sustained climb on a summers day. With the original configuration (oil cooler directly behind the radiator) I had such a problem with 50/50 during a fairly slow speed climb in the Swiss Alps behind Dave Buzz. In the end, I had to leave the formation and fly back down the valley at an increased speed to get the temperatures back under control. Once back on the ground under the advice of Andy Draper, I attacked the lower cowling with a hacksaw to take off a lip that I had misguidedly left on. That made a slight improvement. When I arrived back in UK, I lowered the oil cooler to the optional position. From that point on, G-JULZ never had a temperature problem even in the most sustained climbs to altitude. On the introduction of Evans fluid, the temperature problems in the climb returned. On a summers day it was necessary to level off and accellerate at about 3,000ft to keep the temperatures within limits. With both Evans and 50/50, in the cruise the temperatures will drop to 50 to 60 degrees C. Which is why I am just modifying the air duct exhaust with a temperature controlled 'cowl' flap. Incidentally, I had considered using an oil thermostat, but gave up on the idea when I read on this site that the oilstat mod did not work too well. The bottom line is that if you chose to use Evans coolant on the standard Europa configuration, don't be surprised if you experience unnecessarily high CHT temperatures. regards, Mike. ________________________________ Message 10 ____________________________________ Time: 11:48:54 AM PST US From: "Sidsel & Svein Johnsen" Subject: Re: Europa-List: Europa Widen Shoulder width door mod. Will, Bob, The attached may give you an impression of the added width - not much in mm/inches, but "it's all a matter of perception" also in this case - it feels good. The indent in the door of course matches the sill. On the right side you will notice a wider flat under the sill proper - this is a thin cover of 2 plies of bid covering electric cables (similar on the left side, covering xponder antenna cable and some el. cables). Together, this gives a nice area to rest/press your upper arm against. Even if you do not need it for cables, you might consider adding it to gain the same benefit (use some foam and cover with bid).

My coolant system has an electric heater in it, and is filled with NPG. Reasons are that cooling is not the problem in my region, heating is. To my surprise the coolant liquid sizzles in that heater, so it is micro-boiling. That while i expected it not to form bubbles on the element. If the stuff micro-boils at the heater, it will certainly do the same in the cylinder heads. This experience imho nolliefies the argument that NPG would prevent micro-boiling. The only remaining advantage for me would be that it would not pressurize the system, preventing blow-outs.

It therefore falls to me to announce that his lovely trigear G-FIZY took to the skies at 1600 local, yesterday afternoon ( 3rd), in the very capable hands of David Hunter. David took off from R/W 06 at Kemble for a 30 min flight, reporting just a couple minor points to be sorted out. He then took to the air again for a slightly longer flight, including a couple more landings. May I be the first of many hundreds to offer my sincere congratulations.

Mike: the PFA decision was to abruptly ban the use of Evans because it is flammable. Ron: Clearly you had fun playing with flammable liquids, but nothing in your data adds to critical decision making here. Gilles: Your comments about heat of vaporization may or may not apply. It depends totally on the dynamics, by which I mean the rate of nuclei formation. Dean and the Rotax engineers seem to be of the opinion based on their teardowns of damaged engines that stable nuclei do in fact block heat transfer. The proof would be to place a fiberoptic endoscope in a coolant channel during typical conditions and see the phenomena, along with placing micro -thermocouples in well points milled into the block next to the channels and in the fluid inside the flow channels. This of course ignores secondary effects like the conversion to turbulent flow due to nucleation and the consequent drop in flow rate ;-) (God, I loved my course in fluid dynamics 30 years ago) In the mean time, the current best practice per the Lockwood/Vogel organization with the tacit approval of the Kodiak group is: Use 50/50 with the 1.2 bar cap. NB: The day after SnF, I put in the new 1.2 cap ($29. at CPS, $74 at Lockwood at SnF, since reduced). During the next taxi run to the active, all the coolant blew out my overflow tank.

Theory should be used to explain observed facts not the other way round. The latent heat of vaporization of water is 525 calories per gram, whereas it only takes one calory to raise the temperature from 99 deg. to 100, boiling point. It won't boil until it gets the other 524 calories. Thanks for your clear thinking.

It is normal to control the exhaust rather than the inlet air which is what I did in both cases. Even with the outlet for the XS cowl being fully closed it made little difference to controlling either oil or coolant temperature. The only flap I have seen work really successfully controls the inlet air. The design uses a flap which can be raised to close off airflow whilst airborne or lowered on the ground to encourage increased airflow.
