Rating Aviation Fuels-in Full-Scale Aircraft Engines - A report of the Cooperative Fuel Research Committee 360112
THE Cooperative Fuel Research Committee in May, 1933, approved the program of the C.F.R. Aviation Gasoline Detonation Subcommittee.
This paper constitutes the report covering results obtained in carrying out that program involving tests made to ascertain whether octane-number determinations made by the C.F.R. Motor Method (A.S.T.M. Designation D357-34T) of rating motor fuels correlate satisfactorily with the behavior of widely different types of aviation fuel in representative full-scale aircraft engines.
These tests were made with four multicylinder aircraft engines by the Wright Aeronautical Corp., the Pratt & Whitney Aircraft Co., the Lycoming Manufacturing Co., and the National Bureau of Standards.
The C.F.R. Committee has approved a further program for full-scale engine detonation work with aviation fuels above 87 octane number. A statement of this program is included as an appendix of the report.
In this study of detonation testing methods applicable to high octane fuels, a sub-committee has been organized recently to coordinate the activities of the laboratories interested in the investigation and possible development of laboratory practices yielding results in correlation with full-scale data, as provided for through the cooperating aircraft engine laboratories.
