They use reductions from auto transmissions, sun and planetary and are considered reliable relating to two and four strokes. (Between the two) They are considered that if they start they will get you home. The seals don't FAIL suddenly and nothing else comes poking out the side. like pistons do.  They are hard to silence (Like a 2 stroke). Nev

In my RX2 I could pull the engine out and rebuild it with a new set of seals over a weekend, so I wouldn't call them reliable.  We have a big sealing advantage with a circular combustion chamber seal because we can use steel rings. The Wankel has to seal at 90 degrees, so our seal needs to do a couple of 90 degree turns. At light loads or intermittant loads the silicon seals are not overheated, but at constant hard load, such as a country drive into the wind at high speed the seals would usually burn out by the end of the trip with the engine still running, as you said, but the car would be covered in steam if stopped at a set of traffic lights. There was very little power below 4,000 rpm, but the car would spin the wheels at 160 km/hr and cruise at 209 km/hr.

A racing Wankel and an aircraft engine are both constant load engines, but the Wankel power band is up too high for an aircraft.

You could use a prop reduction gear but that starts to add the weight that was the purpose for going there in the first place, and you have the issue that the seals are consumables, and you can't do a seal change in the sky.

It was slowed down by Turbo having to explain that the consultation "What are you here for today?" was free but the jab was 50 bucks, but they took it and poured in.

While this Site has ample facilities for commercial advertising, TREAT begs Een's forbearance for a short explanation of the TORS system which does so much for the environment. The TORS is very cheap, just AUD$30.00 + GST. It consists of a long rope and a reel. If you have an engine failure you simply release the engine and the rope automatically reels out until you have landed. Then all you have to do is reel the motor in, lust like fishing. In tests Professor Claret from Turbine Research has found the only environmental damage so far was mild rope burn on three wild ducks which would have been shot anyway.

As usual the Seagull has been totally reliable, and for those labouring over the last ten thousandth of a millmetre, and whether the cold bore will shrink just enough so that the expanding piston cannot seize. With the Seagull you just make the piston 1/8" smaller diameter and mix half a pint per gallon oil and the engine will work for 50 years, no shock cooling, no seizing and the only accessory you need is a packet of band aids to .........

Notice that to inexperienced spectators the action doesn't look spectacular at all until it goes wrong.

I was cured of doing steep turns etc over properties when I realised it didn't look spectacular from the ground, and people really didn't take much notice.

You're looking at "below the line" advertising where a Party advertises something anonymously.

Victoria is introducing a very small, petty cash. tax on EV based on road use, just like all the other vehicles which use the roads.

This is so that, over time, if the market share of EV does grow from its current 0.5%, then this will replace the tax we are currently paying on ICE vehicles. Both ICE and EV, equally use roads.

Dear NESers. The Skipper is flabbergasted that Turbo would voluntarily introduce his outboard exploits again.

 

Cappy therefore feels assured that Turbo has provided permission for his best mate to publish a photo (see below) of one of Turbo's outboard exploits from 2017 when he was messing around with the extremes of 25 hp.

 

This pic was previously part of a Non-Disclosure Agreement between Turbine Marine Propulsion Inc and the ABC.

The handwriting has been confirmed by experts to be that of the great man, Turbo himself.

Turbo admits that this was some of his earlier work (when he was about 10, before the Nuns belted him for swearing); fully ported it breathed like a horse, with it's big Mikuni, and chamber cleverly built down the leg. Problem was the throttle stuck wide open on its first trial on Coackatoo Lake, and Turbo had borrowed a duck punt from a local shooter. Duck punts have a flat bottom nd wide beam to slide around in shallow swamps, and the outboard had a long leg, so wherever Turbo pointed the prop, that's where the punt went. On the few occasions the prop and bow lined up, as soon as Turbo tried to turn, the punt went along sideways, at one stage straight down and alley of duck shooters stationed in hides. It's testament to the poor shooting of hunters that Turbo's hide wasn't full of No 6 shot.

....smooth use of the controls.

This was a diversion by Cappy who once again had come to a premature full stop in the previous posts. It was happening a lot these days.

It was when Turbo was looking at the Avatar that he noticed Cappy had flown/bought/wish listed a German Motoren Flugelshchitingliden, and that it had the engine on a pole above the fuselage, so in the event of an engine failure it would immediately nose up, compounding the impending attitude problem, and Turbo thought back to his own towling hat days when he owned an old Blanik and decided to convert it to a motor glider. He had one outboard left that hadn't blown the motor, a Seagull 3.5 and he artfully mounted this UNDER the Blanik, worked the head for 40 hp and fitted a wooden prop. He made a cradle on castors for the take off.

You had to be careful where you were standing when you pulled the starter rope; much the same as in a dinghy,but it started well after some tuning, and the first take off went smoothly with the Blanik performing very well, so well that Turbo suddenly realised he was almost out of fuel.

At the same time he realised the one Achilles heel in his design; the cradle was still on the ground and he couldn't land on the engine.

As he came in at his usual short-field height the prob carved a U shape in the hedge. He saw the cradle in the distance; it had run off the runway at an angle....................

An Aside ..... A rare picture today, from my drone, of Onesie going stir-crazy sitting by his pool during day 2 of lockdown, while his boat & seaplane (avref) are resting, unused on their pontoons on the Swan.

 

The pool looks nice now, notice the white pavement all around it; that's where he used to keep his collection of Chamberlain tractors and spare parts. |The waste oils and rusty water used to flow2 across the pavement and into the pool. You could still swim in it, but there was a lingering steely taste in the water abd the chicks used to climb up on the tractors where you couldn't get to them.

".......You XXXX!; Cappy would NEVER do that to me!" 

Cappy was standing next to Turbo beside the duck pond, but Turbo moved first, ripping off an RMW boot and throwing it expertly at  Mavis's exposed rump.

Not many people know that in the 1930s old RM started putting steel into the heels of the boots he made for the Ringers. It has nothing to do with boot structure but turned the boots into a weapon which when thrown in a certain way utilised the spin energy. If a calf got away, instead of tiring the horse a Ringer would rip off a boot and slug its thick backside.

It did the trick with Mavis who popped out of that fuselage and landed in the pond.

Turbo didn't draw any attention to himself, and all she could see through her mudcaked eyes was Cappy who had not moved.................

Turbs my GUESS is that there was some heat capacity available beyond the continuous heat duty and this got used up. 

 

In electronics, we have usually high thermal mass 'slugs' under power silicon chips: 

 

IE a sandwich of  chip >> copper slug >> aluminium heatsink.

 

For sustained heat removal , the heat just travels through the lot to the heatsink. But the amount of heat that can be removed per second is limited .

 

For transients and momentary overloads , the high heat capacity of the copper slug can absorb the heat pulse  out of the silicon chip, and stores it for (slower) forwarding onto the heatsink over time.  

 

I gather there is a bit of that going on in said drag strip service, a 2nd order effect. IE you have transient loads that have some heat capacity , and sustained dissipation limits. the piston will heat up fast, and there will be some heat capacity in the conrod, bore walls etc , and once those heat wells are filled up (come up to temperature), the piston temp rise will accelerate. 

 

It's oval track racing, not drag racing with a quarter mile circuit made up of two long straights with a double corner each end (effectively an oval), and covered in about 11 seconds. Acceleration starts  about half way through the first corner, and ends at the end of the straight, so there's a long burst of full power demand followed by a short period of trailing throttle over and over again. We would call that an Intermittent Power Application where the engine gets some relief in the combustion chamber. RPM variance is about 1500 each time.

I resolved my problem by cooling the engine with fuel, and went from piston replacements every few races to several years., but I had an advantage in that I was using Methanol, which you can run much richer than petrol before power loss.
