Performance Analysis of a Wing-In-Surface-Effect Craft on the Basis of Extreme Ground Effect Theory

基于极端地面效应理论，对无厚度s型机翼的升力、阻力和俯仰力矩进行了分析。认为s型翼的稳定性是可行的。机翼展弦比为0.625。飞机的巡航速度、巡航范围、静俯仰稳定性、所需功率和燃油消耗率按通常的方法进行估计。在福冈-釜山和新潟-符拉迪沃斯托克航线上使用了40米长的全翼型模型飞机，以估算其直接运营成本。结果表明，与任何可能的或在不久的将来可能的运输方式相比，工艺是两条路线上最有效的运输方式。研究结果发表在在悉尼举行的第四届国际快速海运会议上。采用计算机仿真方法，对有限厚度的翼型进行了机翼特性计算。在悉尼举行的WISE至Ekranoplan GEMs国际研讨会和1998年日本造船学会秋季会议上报告了结果。

Lift, Drag and Pitching moment of a S-shaped wing without thickness are analyzed on the basis of the Extreme Ground Effect Theory. The S-shaped wing is considered that its stability is feasible. The aspect ratio of the wing is 0.625. Cruising speed, range of cruising, static pitching stability, required power and fuel consuming rate are estimated by an usual manner for aircrafts. A model craft of all-wing type with 40m length is applied to routes Fukuoka-Pusan and Niigata-Vladivostok to estimate its direct operation costs. Results show that the craft is the most efficient method of transportation on the two routes in comparison to any possible or possible in near future. The results are reported on the Fourth International Conference on Fast Sea Transportation held in Sydney.A wing characteristics are evaluated for wing profiles of finite thickness by a computer simulation method. Results are reported on the International Workshop on WISE up to Ekranoplan GEMs held in Sydney and on the Autumn Meeting of Japan Society of Naval Architects in 1998.
