Linear correlations of principal parameters for the preliminary design of twin civil jet aircraft

摘要

Purpose - The purpose of this paper is to simplify the preliminary design process as well as the initial evaluation of existing design parameters of civilrnjet aircraft; to include noise level consideration right from the start of the design process; and to form a current database of civil jet aircraft designrnparameters.rnDesign/methodology/approach - Simple (linear) correlations are found between key design parameters.rnFindings - Direct linear relationships are found between design parameters including noise levels. Simplified preliminary design process.rnOriginality/value - New correlations which simplify the current procedures for preliminary design. In addition, the noise is included right from thernbeginning of the design. Finally, a new database is formed with specially selected aircraft that is current and covers a wide spectrum of sizes.
