Abstract

Zadatak ovog završnog rada je analizirati aerodinamičke značajke konfiguracije kanard –krilo– rep nalik na borbeni zrakoplov Chengdu J-20. Za analizu se koristi zrakoplov njemu nalik nazvan MD-20. Iz tog modela su izvučene sve potrebne dimenzije. Nakon definiranja geometrije provodi se analiza aerodinamičkih koeficijenata posebno za izolirano krilo, izolirani kanard, izolirani rep te konfiguraciju. S definiranim aerodinamičkim koeficijentima provodi se analiza uzdužne statičke stabilnosti i ravnotežnog leta zrakoplova za određene uvjete leta te je u analizi razmatrano za različite položaje središta mase. Na dijagramima su prikazani rezultati analiza promatranog modela zrakoplova.

Abstract (english)

The task of this paper is to analyze the aerodynamic features of the wing-canard-tail configuration similar to the Chengdu J-20 fighter aircraft. A similar aircraft named MD-20 is used in this analysis. Necessary dimensions were extracted from that model. After defining the geometry, an analysis of the aerodynamic coefficients was carried out, separately for the isolated wing, isolated canard, isolated tail and configuration. With the defined aerodynamic coefficients, an analysis of the longitudinal static stability and trimmed flight of the aircraft is conducted for certain flight conditions, and different positions of the center of mass were considered in the analysis. The diagrams show the results of the analysis of the observed aircraft model.
