TL;DR: In this paper, the experimental results of towing tank tests in calm water on a single-step hull model are presented, and the same flow conditions are analyzed via Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulations (LES), with different moving mesh techniques (overset/chimera and morphing grid), performed at different model speeds.

TL;DR: This paper defines what it means by trim, examines a variety of trim conditions that have proved useful and derive the equations defining those trim conditions, and presents a general approach to trim through constrained minimization of a cost function based on the nonlinear, six-degree-of freedom state equations coupled with the aerodynamic and propulsion system models.

TL;DR: From the results of RANS simulations on a modular model of a representative regional turboprop airplane layout, the authors have developed a modern method to evaluate the vertical tail and fuselage contributions to aircraft directional stability.

TL;DR: In this paper, the authors present some results of the flight test campaign conducted on the Tecnam P2006T aircraft, on the occasion of its certification process. This twin-engine propeller airplane is certified under the normal category CS-23 and FAR 23.

TL;DR: The present note introduces the ongoing development of the Java Program Toolchain for Aircraft Design (JPAD), a Java-based desktop application for aircraft designers to provide a library and a set of companion tools based onmodern software technology as a support for typical preliminary design studies.
