A Computer Program For Weight Estimation Of Propeller Driven General Aviation Aircraftud

摘要

This Document Describes The Predesign Weight Estimation Method Of An Aircraft And A Computer Program For The Calculation And Summation Of System And Sub-System Weight Elements For Subsonic Civil Aircraft . The Method Is Based On The Statistical Analysis Of Historical Weight Data For The - Components Of Similar Aircraft Configurations. The Correlations And Correlating Parameters For General Aviation Aircraft Are Presented.udududThe Capabilities Of The Program For Calculating The Centre Of Gravity Location Evaluated From The Calculated Individual Component Weights And Weight Reduction Due To Use Of Composite Materials And Advanced Light Alloys Are Described In Brief.ududThe program was used to estimate the weight of four. existing transport aircraft which was found to be well within the acceptable limit . Finally the code was used to estimate the weight and c .g . of NAL's light transport aircraft.udud
