A NEW STERN HULL CONCEPT

Abstract

Since the apparition of the first commercial ships, the naval architects ceaselessly were racking their brains how to improve the existing hull forms. This paper tries to draw attention on and briefly documents the investigation work performed towards realization of a NEW STERN CONCEPT – having radial crenellated-corrugated sections (Tanasescu’s stern shape) - devised by the author. For a long time, the conceiver thought how to design the two systems - hydroframe system and propulsion system - very important for a ship, so that the hydroframe may meet the propulsion and the propulsion may meet the hydroframe in an optimal way. Main objectives of the new suggested stern concept are designing more energy efficient, with lower noise generated level and better directional stability, ship hull forms. These are the fundamental problems that were shortly addressed and partially presented analytically, numerically and experimentally, hereinafter. Of course, the reasonable, successful practical applications of this new technical idea for the real world next generation of commercial ships depend on quickly devising suitable technological ideas.
