70’Yacht Design Marine Engineering Section

With the rapid development of China’s economy for many years, the yacht industry as marine economy of the emerging new industries and tourism and leisure industry concern, becoming the housing, cars after the new hot spot for domestic consumption, as water consumer durables and high-tech products, as China’s most attractive and most promising industries.In the70’yacht design work, I mainly responsible for part of the design engineer. This article from the ship systems, air conditioning and ventilation systems, cabin ventilation, exhaust systems, shafting and propellers strength of other aspects of the detailed design.Ship systems, mainly for the boat bilge water system, freshwater systems, sewage systems, fire systems and fuel systems were designed in detailAir conditioning and ventilation systems, the chapter mainly based on national standards GB/T13409-92living at the ship to go on the air conditioning and ventilation design parameters and the calculation method and the relevant requirements of ship design manual, the whole boat air conditioning and ventilation systems were calculated. Ultimately select the requirements applicable to the yacht air conditioning system.Cabin ventilation and smoke, due yacht mostly used on diesel engine speed diesel engines, so the cabin ventilation and exhaust areas are mainly provided by the manufacturer according to the host requirements for the design.Shafting and propellers, as the boat’s propeller shaft speed is high, so select630stainless steel. The propeller design, since no domestic high-speed propeller design patterns, so we took outsourcing propeller, propeller in this article only the intensity of accounting.
