航海模型：是指船舶、軍艦的模型，通常是指體育運(yùn)動項目中的模型制作、比賽、展覽、表演。它是一項科技、軍事、體育、文化教育活動。通過制作模型、比賽、展覽、表演等多種形式，了解關(guān)于船舶、海軍、海洋方面的各種知識，提高他們的綜合素質(zhì)。

Navigation model: refers to the model of ships and warships, usually referring to the production, competition, exhibition, and performance of models in sports events. It is a technological, military, sports, cultural and educational activity. By creating models, competitions, exhibitions, performances, and other forms, we can gain knowledge about ships, navy, and the ocean, and improve their overall quality.

航海模型是具有科技性的體育運(yùn)動項目，通過研究制作、在水上操縱各種模型，學(xué)習(xí)航海科學(xué)知識。航海模型在我國已開展五十余年，受到廣大群眾，特別是青少年的喜愛。航海模型種類很多，分類的也各有不同。按照世界航海模型運(yùn)動聯(lián)合會NAVIGA的規(guī)則，航海模型的競賽項目分為五類：

Navigation models are technological sports events that involve studying, creating, and manipulating various models on water to learn about navigation science. Navigation models have been developed in China for more than 50 years and are loved by the general public, especially teenagers. There are many types of navigation models and their classification varies. According to the rules of the World Federation of Navigation Model Games NAVIGA, the competition events for navigation models are divided into five categories:

1、動力艇航海模型（M），內(nèi)燃機(jī)動力圓周競速和無線電遙控單艇或多艇競速的競速艇模型；

1. Power boat navigation model (M), a racing boat model with internal combustion engine power for circular racing and radio remote control for single or multiple boat racing;

2、仿真航海模型（C），只評比建造工藝技術(shù)水平的艦船、設(shè)備及建造場景等各類模型；

2. Simulated navigation model (C), only evaluating various models such as ships, equipment, and construction scenarios with advanced construction technology level;

3、耐久競速艇（FSR），無線電遙控，按專用競賽場地、航線在規(guī)定的較長時間里集體競速繞圈航行的競速艇模型；

3. Durable Speed Boat (FSR), a radio remote controlled racing boat model that collectively races and navigates in circles for a specified period of time according to a dedicated competition venue and route;

4、帆船模型（S），它是-種無線電遙控帆船模型；

4. Sailing model (S), which is a radio controlled sailing model;

5、仿真航行航海模型（NS）。

5. Simulated Navigation Model (NS).

軍事模型是以軍事外形（系統(tǒng)等外部肉眼可見部件）為形象按一定比例縮小的模型，一般用于教學(xué)、展覽、實驗及裝飾等。航海模型中的軍艦、潛艇、航空母艦等軍事則就屬于軍事模型，而宏辰軍航專注大型、仿真軍事模型類。

A military model is a model that is scaled down based on the appearance of military weapons (external visible components such as weapon systems) and is generally used for teaching, exhibitions, experiments, and decoration. Military weapons such as warships, submarines, and aircraft carriers in navigation models belong to military models, while Hongchen Military Airlines focuses on large-scale, simulated military models.
