FIELD: transport. ^ SUBSTANCE: invention relates to transport facilities, particularly, to self-stabilising hovercraft. Hovercraft features canard configuration and comprises fuselage, front horizontal tail, primary tail wing, vertical tail with rudder and sustainers with propellers. Primary tail wing and front horizontal tail are arranged relative to center of masses with relation between arms Ltail/LFGT=0.81.2, where Ltail is tail wing arm, LFGT is front horizontal tail arm so that distribution of lift forces between front horizontal tail and tail wing makes YFGT/Ytail=0.81.2, where YFGT is lift of front horizontal tail, Ytail is lift of tail wing while absolute arm of front horizontal tail LFGT is selected from the range LFGT/bMAC FGT=52, where bMAC FGT is mean aerodynamic chord of front horizontal tail; at elongation of front horizontal tail FGT=24 and elongation of primary tail wing tail=34 so that relation between lengths of mean aerodynamic chords of wing and front horizontal tail equals bMAC FGT/bMAX tail=0.951.05, where bMAC tail is mean aerodynamic chord of tail wing. Starting engines with screws may be arranged at fuselage nose section while sustainers with propellers may be arranged at fuselage tail section. ^ EFFECT: optimum configuration, reduced noise and higher payload. ^ 2 cl, 2 dwg |
