Abstract
FIELD: aeronautical engineering; manufacture of seaplanes and ground-effect craft.SUBSTANCE: proposed seaplane has wing, tail unit and power plant. Seaplane is made in form of swept-back flying wing with extension in central section. Located on lower surface of this wing is longitudinal planing step and extensible transverse planing step is mounted in CG area; transverse planing step is used to reduced wettability at takeoff and landing. Wing may be formed by supercritical profile along axis of symmetry changing to profile of positive camber at boundary of extension.EFFECT: improved flight characteristics; improved lifting characteristics of wing.2 cl, 1 dwg
