Types of heat generation in Ukraine in 2016 and their cost

In 2016, private consumers of heat in Ukraine receive the heat from the following sources: The most common one is electricity, which means electric boilers, electric fireplaces and heaters of different kinds. Skipping some details, in most cases the ultimate source is hydropower. Possible sources are nuclear power and thermal power stations. For the most

Renaissance of the Yoke Drive

In September of 1980, Professor Dennis Chaddock of Quorn, England, stopped by Columbus to see my stirling engines. While demonstrating the 15cc alpha engine for him, I noticed that it seemed to take a longer time to come up to speed than the rhom­bic engines. I knew at once I’d better retest the 50cc yoke

Model airplane fever

Model aircraft engines have always appealed to me, and when Flob McConaghy demonstrated the world’s first model aircraft stirling in radio controlled flight, I knew I had to try my hand at a model aircraft stirling. Rob had used (and still favors) pressurization, but I decided to stay atmospheric, for simplicity. The key would be

The D-90 Engine

The excellent performance of the D-60 engine convinced me to proceed with the next step, which was to redesign the engine for limited production. l decided that any production engine would have a cast block, rather than one carved from bar stock, to decrease the time necessary to machine it. The expense of the pattern

Diversions

A period of extended disillusionment followed this brief initial run of the 50cc yoke drive engine. My stirling work continued, however, and considerable time was spent thinking of ways to create extended surface area in heaters. Eventually, I decided to at­tempt an investment cast, externally and internally finned, stainless steel heater head. After overcoming the

The Yoke Drive

The success of the small alpha produced a burst of activity. By December of 1976, I had devised the yoke drive mechanism (now generally referred to in the literature as the "Ross linkage") and a method to dynamically balance it (US Patent 4,138,897). The 15cc alpha engine was immediately modified to incorporate the yoke drive,

Dead Ends and New Beginnings

Why didn’t I simply stay with the 65cc rhombic engine and develop it further? I cer­tainly understood that it had a great deal of unrealized potential, even as I moved away from it. An extended surface area heater, additional regenerator volume, increased working pressures, anti-friction bearings on the connecting rods, and other more or less

Other Rhombics

The relative success of the 65cc engine inspired a series of other rhombic designs, some actually built, others not. Among the engines actually built was a small 11cc demonstrator engine designed for an article in Model Engineer magazine. This engine employes exactly the same rhombic geometry as the 65cc engine, but scaled-down to half size.

Getting Started: The First Ten Years

My active interest in stirling engines began in 1971 when I discovered the Philips literature and was inspired to design an air-charged stirling of several horsepower for use on a bicycle. The project was expected to take about a year. My initial design was a complex mess, featuring twin double throw cranks, scotch yokes with

Some Generalizations about Design

The three basic types of stirling described above may employ a wide assortment of possible crank drive mechanisms, or none at all, as in free piston stirling engines. The main requirements are high mechanical efficiency and simplicity, with other important considerations including good dynamic balance, the ability to operate with minimal lu­brication, and compactness. But
