Abstract

U ovom diplomskom radu napravljen je model aerodinamike nadzvučnih brzina modernog lovačkog aviona s konfiguracijom kanard-krilo, nalik na Dassault Rafale. Prikazane su osnove geometrijske i inercijske značajke aviona. Metodama projektne aerodinamike procijenjene su aerodinamičke značajke aviona za normalnu silu i moment propinjanja, za bočnu silu i moment skretanja, te za moment valjanja. Procjene su napravljene za dva Machova broja: 1,2 i 1,6. Nadalje, određeni su linearni modeli dinamike leta i analizirana je stabilnost u odabranim režimima nadzvučnog leta. Linearno uzdužno i bočno gibanje aviona je razmatrano odvojeno. Provedena je ocjena kvalitete direktnog upravljanja u odabranim režimima nadzvučnog leta. Konačno, pregledno su prikazani svi rezultati dobiveni za nadzvučni let zajedno s ranije dostupnim rezultatima za dozvučni let.

Abstract (english)

In this thesis supersonic aerodynamics model for modern fighter aircraft with a canard-wing configuration, similar to Dassault Rafale, is made. The basic information about geometric and inertial characteristics of airplane are shown. Airplane aerodynamic characteristics for normal force and pitching moment, for side force and yawing moment, and for rolling moment are evaluated using analytic aerodynamic methods. Evaluations are made for two Mach numbers: 1,2 and 1,6. Moreover, linear models of flight dynamics are made and stability in selected regimes of supersonic flight is analysed. Linear longitudinal and lateral motion of the airplane was considered separately. Flying qualities of airplane in selected regimes of supersonic flight are evaluated. Finally, all results obtained for supersonic flight are presented together with previously available results for subsonic flight.
