Flying tests of radio controlled models of Wing-in-Ground Effect (WIG) craft were conducted using 3 models of TN-1,2 and -3 at Tottori University, and other 3 models of NT-1,2 and MNT-3 at Nagoya University.TN-1 had a Lippisch wing with a canard, which deflrct slip stream of a propeller mounted in front of its nose and drived by a gas engine. NT-1 had an ordinary flying-boat type. Its wing was a modified Lippisch wing, whose leading edges were cut out to introduce slip streams of two propellers mounted in front of its nose and drived by two electric motors. These two types of models revealed that they were suitable for a high speed and high efficiency craft. From this time, weight of research effort was put on the development of a low speed and small craft at Tottori University. On the other hand, at Nagoya University, effort was continued to develop a high efficiency craft. TN-2 had a ram wing, which could achieve a low wing loading and was suitable for a low speed craft. Wing of NT-2 … More was rectilinear instead of a Lippisch wing to maximize the effect of power augmented lift (PAR). TN-2 had satisfactory performance except the tendency of pitch up. To control pitch up, TN-3 was designed and constructed. Two electric motors of NT- 2 were not enough powerful for its model size. A new model MNT-3 was designed with a gas engine. These last two models achieved constant low altitude flight above water surface.During this research project, investigators in Tottori University had a chance to advice another project of manned model of WIG. A 1-seater and a 2-seater were developed in success. They are now making effort to develop a production model. At the same time, investigators in Nagoya University also advised a project of a manned model of PAR-WIG. This model succeeded to a continuous jump. They obtained many valuable data of PAR-WIG development.From these results, we find out that one of important problem is pitching stability for the practical use of WIG. We will study the problem by making use of numerical simulation. Less

使用鸟取大学的TN-1、2和-3模型以及名古屋大学的NT-1、2和MNT-3 3个模型进行了地面效应飞行器无线电控制模型的飞行试验。TN-1有一个带有鸭翼的Lippisch机翼，它可以偏转安装在其机头前面的由燃气发动机驱动的螺旋桨的滑流。NT-1是一种普通的飞艇类型。它的机翼是一个改装的Lippisch机翼，它的前缘被切断，以引入安装在机头前面的两个螺旋桨的滑流，并由两个电动马达驱动。这两种类型的模型表明，它们适合于高速高效的飞行器。从那时起，鸟取大学的研究工作重点放在了低速小型飞船的开发上。另一方面，在名古屋大学，继续努力开发高效率的工艺。TN-2有一个冲压机翼，可以实现低机翼载荷，适合低速飞行器。NT-2…之翼More是直线的，而不是Lippisch机翼，以最大限度地发挥增力升力(PAR)的效果。TN-2除有上升趋势外，其他性能均令人满意。为了控制俯仰，TN-3被设计和建造。NT-2的两个电动马达的功率不足以满足其模型尺寸。设计了一种新型的MNT-3型内燃机。在这项研究项目中，鸟取大学的研究人员有机会为另一个载人假发项目提供建议。一款单座和一款双座成功开发出来。他们现在正在努力开发一种生产模式。与此同时，名古屋大学的研究人员还为一个载人假发模型项目提供了建议。这一模式成功地实现了连续跳跃。他们获得了许多有价值的假发发展数据，从这些结果中我们发现，假发实际使用的一个重要问题是俯仰稳定性。我们将利用数值模拟的方法来研究这个问题。较少
