FIELD: free molding of thermoplastic polymers, in particular, imparting the more stream-line form; perfect aerohydrodynamic form with the minimum drag to the medium flow, to the blanks of models of transport facilities. SUBSTANCE: the method consists in heating of the blank surface layer up to the transition to the plastic state, molding by action of the heated high-speed medium flow up to the decrease and subsequent stabilization of blank drag to the flow. The invention provides for production of various stream-line form of the model depending on the flow speed, model material and medium type and may be used for construction of newly designed objects. EFFECT: facilitated procedure. 1 tbl |
