Part 2: O-315 through OL-1430

This is the second part of the Continental engine compilation. It includes the engines with larger displacement, namely from the O-315 through the OL-1430. Again all families of Continental horizontally-opposed aircraft engines are listed in the table of Continental Engine Families. This table gives a compact reference to their chronological and technical development. The Continental introductory material is contained in the first part of the Continental compilation and includes a Table of Equivalence between Continental designations and this Website's designations. The Continental engines of smaller displacement from the O-110 (A-40) through the OL-300 (Voyager 300) are given in the first part and can be reached here.

The TCM Website is very comprehensive and provides specification sheets for all engine models in their current inventory at the TCM Home Page. The Engine Specification Sheets can be found from their Home Page by clicking on "Visitor Services" under the "Customer Center" heading. From there, you can click on "Engine Spec Sheets" and then scroll through the engine models to find the desired information. All models listed on the Website are indicated below as being in current production.

OL-1430 -- {5.5 / 5.0 / 1425.5} / {139.7 / 127.0 / 23,359}

The US Army at McCook Field (later at Wright Field) began cylinder research in 1929 under the direction of S.D. Heron and others. By 1931, a twelve cylinder, V-12 liquid-cooled engine with {4.625 / 5.0 / 1008.0} had been designed. In 1934, the US Army increased the cylinder size to 1425 cu. in. for a V-12; this was redesigned further into the OL-1430 and tested in 1938. The motivation for a high-power HOAE was the promise shown for low-drag, in-wing installation, but this soon was seen as impractical (see, also, the Lycoming OL-1230). Later, the OL-1430 was redesigned into the Continental IV-1430, which was an inverted V-12. The development of the OL-1430 has been discussed in the book by Schlaifer and Heron (S&H). Specific references can be found on pp. 21-23, 26, 75, 80, 82, 268-273, 288-289, 294-295, and 297-302.
