The invention relates to a modularized immersed water jet propulsion self-propelled ship model which comprises a ship body, immersed water jet propellers, propeller fixing bases, a ship body supporting frame and a ship body channel complementing module. A propeller mounting groove is preset at the tail of the hull; the lower end of the propeller fixing base is tightly attached to and welded to the immersed water-jet propeller guide pipe, and the upper end of the propeller fixing base extends out of the upper end of the propeller mounting groove and is fixedly connected with the hull supporting frame for carrying out a self-propulsion test. The lower end face of the hull channel complementing module is matched with the hull tail molded line to form a complete hull bottom shell, the upper end of the hull channel complementing module extends out of the upper end of the propeller mounting groove and is fixedly connected with the hull supporting frame, and the hull channel complementing module is used for replacing the propeller fixing base and the immersed water-jet propeller and carrying out a propeller-free hull resistance performance test. Through the modular and replaceable design, the machining difficulty and cost are reduced, and meanwhile convenient installation of the propeller is achieved; and self-propulsion performance and resistance performance tests can be correspondingly carried out on the same ship model.

    本发明涉及一种模块化浸没式喷水推进自航船模,包括船体、浸没式喷水推进器、推进器固定基座、船体支撑架和船体槽道补足模块;船体尾部预设推进器安装槽;推进器固定基座下端与浸没式喷水推进器导管紧密贴合并焊接,其上端自推进器安装槽上端伸出并与船体支撑架固定连接,用于开展自航试验;船体槽道补足模块下端面与船体尾部型线适配以形成完整的船体底部外壳,其上端自推进器安装槽上端伸出,并与船体支撑架固定连接,用于替换推进器固定基座与浸没式喷水推进器,开展无推进器的船体阻力性能试验。本发明通过模块化、可替换的设计,不仅降低了加工难度与成本,同时实现了推进器的便捷安装;且可在相同船模上对应开展自航性能与阻力性能试验。
