Cozy Girrrl

Happy birthday guys.

 

I haven't anything from Karolina in some time, and since return to the USA, Drew has gone 'deep n silent' no doubt re-establishing things.

 

Hope to see you back and posting sometime soon

 

Bruce.

Last I had heard from Karoliina was she was flying every chance she had on business visits to Palo Alto, California and had her USA pilots license, I think working on other endorsments thinking towards commercial. Pretty awesome.

We used those as heating units on yachts, either as a forced hot air unit or circulating hot water going to registers with heaters just like a car. I always preferred the hot water type since you could run it through a 2 gallon RV hot water heater and let the marina (no charge for electricity) pay for your heat. They were noisy little buggers and the greasel ones were a bit stinky, you could usually see one start up from the initial puff of smoke. Most of the small ones had a dribble mat rather than a proper injecter and they'd eventually get all coked up with carbon gunk. I might still have one somewhere in storage.

Why add yet another element of complexity and weight to you airship when you already have an adequate source of heat? Not to mention IT LIGHTS ITSELF ON FIRE!!!

...Chrissi

I was working on that in my sleep last night and woke up realizing I'd have done it out of 4130 tubing as a weldment. Probably lighter and stronger.

 

I think you're going about it the right way, predictable results. Originally I had thought of doing it by welding several plates of aluminum together that had been cut at angles to achive a hinge approximating the original... heavy and not nearly as nice as what you have come up with. So what are you going to do for the gear?

...Chrissi

Here is the final hinge assem for the berkut canopy. The nice thing about this, I can waterjet cut pretty much all of it. keeping costs down. I will have to post machine the counter bores no biggy.. Not sure if I want to tap the "Bow-Tie" cross brace or drill a thru hole and use a ny-lock nut. I'm open for suggestions.

They are going to be assembled only once (hopefully), capscrews with loctite.

I like the way you approached this, very good!

...Chrissi

Happy Birthday Karoliina and Drew !!!

:banana: :banana:

Edge.... WOW

Chris,

Lynn's observation is correct, also you need the reserve for climb out. Since you get 30% of your cooling from oil consider a deeper oil pan, again for more reserve on climb out before the oil gets really hot.

Speaking of hot, Chris we really love ya but you are geographically undesirable, one of us would have to commute!

...Chrissi

Chris, Agreed, its not any hotter than any other, can't really change the boiling point of water all that much except by pressure and not good to monkey about with that too much.

..Chrissi

Chrssi,

 

Since you mentioned this during your all too short visit to the Big Onion...uh, Houston, I addressed it with both my engineering friends (2) and Velocity, Inc. However, I have yet to get the model number and do the more proper research. I do have another Mazda oil cooler that is "about" the same size as the very expensive aviation one that Veocity provided. I think it was orignally for a 3rd gen

 

BTW, are y'all coming to the Texas Rotary Roundup north of Austin on May 29, 30 and 31? If not, WHY THE HELL NOT?

 

All the best,

 

Chris

Chris, the history goes that people have blown out aftermarket oil coolers because they are not rated for this pressure, something like 100+PSI at times. I think part of this is due to the need to spray it out in a large volume to the inside of the rotors for the cooling. Hey, the upside is you can sell the very expensive aviation cooler provided by Velocity

Nope, it is my destiny to never get near Austin, I lived in Houston for 6 years and never managed to go there so we are surely not going to drive from our state of Misery all the way to AustenTacious...

 

...Chrissi

Another safety factor used in the water cooled rotary installations is a water pressure gauge so you should see it coming before you pop the pressure cap.

...Chrissi

Yes, the GU canard plans have you attach the hinge points after building the elevators, the Roncz elevato hinge points are embeded into the tubes the elevators are built around, this is a first step thing that cannot be retrofit.

...Chrissi

Dear Chris,

Just make sure you do not use the Velocity cooler. The oil pressure in a rotary runs up to twice what other engines do, people have tried other coolers and they have burst.

Regards, Chrissi

Tman,

On the inlet side of the circuit at the firewall put a ball valve or your regulator valve (and maybe a ball valve). Use just a ball valve with a push pull cable if you wish to regulate temp manually. On the outlet side at the firewall put a check valve.

This way if you have a break or leak in the cockpit nobody gets scalded and you will not steam up the canopy and be practicing IFR flight turning your canopy into one giant Foggle. You will be able to shut off the cockpit circuit completely.

The deltaT accross whatever you use for a core is not enough to heat incoming outside air much above sea level on a good day. So you will need to recirculate air to get heat. Your air supply may be suplemented by a fresh air vent. Marine supply store have a good inline blower. You may need to put a filter capacitor accross the motor leads at the motor to kill off elecrical noise.

Heat is controlled much the same as your car at that point.

If you want heated seats you can spiral a tube under your seat, just make sure it is controllable!

...Chrissi

Chris, we're sort of just down the road from you but Steve Morse who works at Boeing, he's an ME, EAA chapter VP, he has one flying LE and is building another one so would be a better local resource for LE information.

Regards, Chrissi & Randi

Thats exactly where we were headed if we decide we need step(s), hook the cable(s) to the FHC canopy hinges and let the rising canopy deal with the steps.

For sale; $1500, Lincoln Square Wave 175 TIG/stick welder

Accessories: standard torch, ground, argon regulator gauge, pedal control, stick welding cable, Lincoln cart (not shown in picture), water cooled torch adapter (not shown, water cooled torch not included).

 

Great welder, like new condition, clean, used lovingly and not flogged like a used one on ebay from a welding contractor.

 

Buyer picks up here (big and heavy)

Agreed! Most folks are upgrading to this system ..... not swapping it out. You might get lucky and get one out of a wrecked plane or an abandoned project. I'd be checking eBay otherwise ....... Jack is the source.

I was not endorsing either system, just asking what was the problem in obtaining one, both should be available at a competitive price, people tend to hang on to them.

..Chrissi

Bruce,

Whats wrong with ordering one directly from Jack?

Seems like the clamping part needs to be twice as thick in your case.

...Chrissi

Ugh, nightmares from my youth; I remember fighting with the nuns who forced us to eat that crap on toast (Marmite, a competitor) in school down in South Africa. Looked like axle grease, smelled like dog poop, tasted like a beef & yeast salt lick.

...Chrissi

Thats OK Steve, we're sure you will more than make up for it telling everybody how cool the Fein tool i snow =)

...Chrissi

Sorry, have not had time to try the sample tool properly. If you are getting fuzz it is probably one of two things; poor blade design (or dull) or too much heating of the laminate. The ultimate proof will be with a quality Fein blade in it.

...Chrissi & Randi

www.TheProctRecycler.com has them at about 1/3 of the price but you have to turn them inside out to avoid contaminating the layup.

I won't be shaking hands with you:p

...Chrissi

Welcome back Drewby!

Sorry that it was under such circumstances though. The good news is you are nearby, you'll get to attend Osh once more, you are closer to Rough River and Wicks, you have a lot of time available for the plane.

See you around, C&R

Spruce got them cheap from Proctology Supply, mostly right handed Dr's you know?
