FIELD: transport.SUBSTANCE: aircraft has fuselage and swept wing configured for laminar airflow at cruising flight, convex-concave airfoils that feature definite magnitudes of depth, chord and shape along wing span. Wong leading edges are configured to influence the laminar air flow. Maximum depth-to-chord ratio along wing span is related to Mach number of cruising flight. Every version of aircraft is characterised by a definite wing profile selection.EFFECT: optimised airflow.24 cl, 10 dwg |
