Non-dimensional approach to engine thrust and airframe drag for the analysis of measured performance data: aircraft with turbo-jet and turbo-fan engines.
Abstract:ESDU 70020 outlines the method by which the engine and airframe characteristics used in the measurement and calculation of aircraft performance may be expressed in terms of a few non-dimensional parameters and indicates the limitations of such a method. Various additional factors (Reynolds number, thrust angle, centre of gravity variation, power plant operation, gravity variation, flight path length, buoyancy) that affect the analysis of measured performance are discussed and methods by which they may be taken into account in applying this approach are indicated.
