A fluid perspective that becomes the Group’s manifesto, suggesting a unique approach to doing business by placing at the core of ethical and action principles essential values such as freedom of creative expression, reinterpretation of what already exists, preservation of know-how and enhancement of people’s work. The Prada Group is a contemporary interpreter of changing scenarios. In a three- dimensional temporal dialogue that combines the identity heritage of the past with demands and dynamics of the present and future perspectives, creativity molds ideas that transcend the boundaries of the ordinary and create an innovative vision of tomorrow. “Thorough observation and curiosity for the world around us have always been at the heart of the creativity and modernity of the Prada Group. In society, and thus in fashion, which is somehow a reflection of it, the only constant is change. The transformation and innovation of references, at the core of any evolution, has led us to interact with different cultural disciplines, at times apparently far from our own, allowing us to capture and anticipate the spirit of the times.

  • Application of System-Based Modelling and Simplified-FSI to a Foiling Open 60 Monohull
    Journal of Sailing Technology 2019, volume 4, issue 1, pp. 114 - 141. The Society of Naval Architects and Marine Engineers. Application of System-based Modelling and Simplified-FSI to a Foiling Open 60 Monohull Boris Horel Ecole Centrale Nantes, LHEEA res. dept. (ECN and CNRS), France. Mathieu Durand SIRLI Innovations, LUNA ROSSA Challenge, France. Manuscript received July 30, 2019; accepted as submitted, September 11, 2019. Downloaded from http://onepetro.org/jst/article-pdf/4/01/114/2205504/sname-jst-2019-06.pdf by guest on 28 September 2021 Abstract. The increasing number of foiling yachts in offshore and inshore races has driven engineers and researchers to significantly improve the current modelling methods to face new design challenges such as flight analysis and control (Heppel, 2015). Following the publication of the AC75 Class Rules for the 36th America's Cup (RNZYS, 2018) and since the brand new Open 60 Class yachts are all equipped with hydrofoils, the presented study will propose a system-based modelling coupled with a simplified FSI (fluid-structure interaction) method that leads to better understand the dynamic behavior of monohulls with deformable hydrofoils. The aim of the presented paper is to establish an innovative approach to assess appendage behavior in a dynamic VPP (velocity prediction program). For that purpose, dynamic computations are based on a 6DOF mathematical model derived from the general non-linear maneuvering equations (Horel, 2016). The force model is expressed as the superposition of 7 major force components expressed at the center of gravity of the yacht: gravity, hydrostatic, maneuvering, damping, propulsion, control and wave.

  • THE 23Rd CHESAPEAKE SAILING YACHT SYMPOSIUM ANNAPOLIS, MARYLAND, MARCH 15 – 16Th, 2019
    THE 23rd CHESAPEAKE SAILING YACHT SYMPOSIUM th ANNAPOLIS, MARYLAND, MARCH 15 – 16 , 2019 ABSTRACTS Experimental and numerical prediction of foiling monohull dinghy performance A. H. Day, W. Shi, T. King, Naval Architecture Ocean & Marine Engineering, University of Strathclyde F.M. Fresneda, S.R.Turnock, Performance Sports Engineering Lab, University of Southampton The rise in interest in large foiling yachts, such as those in the America’s Cup, has spurred a corresponding interest in foiling applications in monohull sailing dinghies, both for boats designed specifically for foiling, and through retro-fit foil kits. The present study considers the assessment of foil systems for such boats, and specifically the prediction of the necessary foil performance of t-foils with and without flaps. Towing tank and wind tunnel experiments are used alongside numerical simulations. The accuracy of different simulation approaches is examined and the corresponding sensitivity of the predicted boat speed to the numerical method adopted is identified. Results are presented via two case studies, predicting performance for a foiling International Moth, and for a Europe dinghy retro-fitted with hydrofoils. Benchmark data for the numerical simulation is obtained using two approaches. The main lifting foil for a moth dinghy with flap was tested at full-scale in a towing tank at a range of speeds, trim angles and flap angles. Results are compared with published experiment data for a similar moth foil. In a complementary set of tests, the rudder of a Europe dinghy was tested in a wind-tunnel, initially in the original design condition, and subsequently with a T-foil rudder designed for a retro-fit foiling solution.
