How about this hoss?

Looks heavy Philo, maybe good to power a Morgan 3 wheel roadster.

 

 

Right turn Clyde

 

[Dr. Mark]

Good god.

 

The engine type he derived this from is a radial, not a rotary.

 

Although they look similar when they are not running, the radial functions in a conventional manner, with the cylinders turning a crankshaft.

 

In a rotary the crankshaft remains stationary, and is bolted to the vehicle, and the rest of the entire whole damn engine spins. Yikes.

 

Nevertheless...this engine is still insane. Each cylinder displaces 2500 cc's.

Looks like a beefed up knuckle head

Actually Doc..

 

A radial is a circular arrangement of reciprocating pistons, think WWII aircraft.

 

The engine with a fixed crankshaft you mentioned was used in a Sopwith Camel. They always sounded like they were about to fall out of the sky due to their peculiar rpm limiter: it cut off the ignition.

 

A rotary engine ( think Wankle ) uses an eccentric motion in a rotating piston, eliminating the reciprocation of the piston and rods.

 

The only true rotary engine is the turbine.

All I know is it sounds awesome!

 

I would love to see this in a Morgan 3 wheeler.

 

God it sounded good!

The only true rotary engine is the turbine.

 

The term is/was used for both the rotary and the wankel, although in the purest sense, you are correct.

The turbine is the only one that generates is energy purely from the rotational force of the engine.

 

(The Sopwith and Le Rhone came first, though. See below.)

We have a thread over in the antique iron section that discusses the difference between radial and rotary engines in depth, and their use in some very odd German motorcycles.

 

While the rotary aircraft engine died in the 20's, the radial is very much alive and kicking. The HU-16E I crewed on in the Coast Guard had two 1425 horsepower radials. They are some loud sumbitches. I know...I had one about 10 feet from my head.

 

 

Rotary engine

From Wikipedia, the free encyclopedia

This article is about a type of piston engine with a rotating cylinder block. For the pistonless Wankel engine, see Wankel engine. For other engines described as "rotary", see rotary engine (disambiguation).

Rotary engine An 80 horsepower rated Le Rhône 9C, a typical rotary engine of WWI. The copper pipes carry the fuel-air mixture from the crankcase to the cylinder heads, collectively as an intake manifold.

The rotary engine was an early type of internal-combustion engine, usually designed with an odd number of cylinders per row in a radial configuration, in which the crankshaft remained stationary and the entire cylinder block rotated around it. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles.

This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. They have been described as "a very efficient solution to the problems of power output, weight, and reliability".^[1]

By the early 1920s, however, the inherent limitations of this type of engine had rendered it obsolete, with the power output increasingly going into overcoming the air-resistance of the spinning engine itself. The rotating mass of the engine also had a significant gyroscopic precession: depending on the type of aircraft, this produced stability and control problems, especially for inexperienced pilots. Another factor in the demise of the rotary was the fundamentally inefficient use of fuel and lubricating oil caused in part by the need for the fuel/air mixture to be aspirated through the hollow crankshaft and crankcase, as in a two-stroke engine."

 

 

 

There were actually even a couple of Bentley's with these type engines.

 

The idea of having a very large whirling mass of metal very near you is not, to me, very appealing, either in a car or an aircraft.

 

The prop spinning, I can deal with....a 9 cylinder engine and the prop spinning... eh...not so much

I used to work with old gentleman who was a British fighter pilot in WW I. He told me that there Bentley engines used to like to "cold seize" when you put them in a dive. The spinning engine had so much flywheel effect that when it locked up, the plane would do about a half dozen snap rolls. The reason you put the plane into a dive is to getaway from a German fighter. Now you have a German on your tail. A dead engine. Your plane is headed straight for the ground at maximum speed and your plane is in a spin.

Reminds me of an old pilot's saying: "A crash happens when you run out of airspeed, altitude and ideas, all at the same time."
