Document Type: Book (Historical Study). Purpose: Informational. Authority: Author Expertise. Series: Rolls-Royce Heritage Trust Technical Series #3.

NB: The Rolls-Royce Heritage Trust and the Sir Henry Royce Memorial Foundation are closely related. From "Rolls-Royce: The Pursuit of Excellence" (1984): "Both organisations share the history of the early days and work closely in harmony. This Historical Series of books was started by the Trust and it is intended that a series shall follow, produced by both organisations in the same format, thus building up an embracing library of true Rolls-Royce history."

Scope (from Foreword and Introduction: "The Trust is publishing this facsimile report in the Technical Series as a tribute to one of Rolls-Royce's many unsung heroes, the late Alan Yarker. Whilst the report built on previous work begun by Jimmy Ellor, and was written by a team of three, Alan was responsible for the majority of the ground work, data manipulation and interpretation required."

"We shall, therefore, proceed immediately to the main problem of investigating the relationship between the factors affecting the charge consumption of the engine."
