本発明はホーバークラフト、特に浮上ファンの改良を図
ったホーバークラフトに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a hovercraft, and particularly to a hovercraft with an improved levitation fan.
第５図に示すように、従来、ホーバークラフト１の艇首
部２に浮上ファン３を配置する場合、浮上ファン３を、
その軸心４が垂直方向あるいはほぼ垂直方向を向くよう
にホーバークラフト１の主構造体５内に配置されている
。As shown in FIG. 5, conventionally, when levitating fan 3 is disposed on bow section 2 of hovercraft 1, levitating fan 3 is
It is arranged within the main structure 5 of the hovercraft 1 so that its axis 4 faces vertically or substantially vertically.
このため、ホーハークラフト１の前進中、ホ−バークラ
フト１の前進に伴う空気の流れと上記浮上ファン３に吸
い込まれる空気の流れがほぼ９０°相違するため、浮上
ファン３の吸い込み効率が低下する欠点があった。Therefore, while the hoovercraft 1 is moving forward, the air flow accompanying the forward movement of the hovercraft 1 and the air flow sucked into the floating fan 3 differ by approximately 90 degrees, so the suction efficiency of the floating fan 3 decreases. There was a drawback.
また、浮上ファン３はホーバークラフト１の主構造体５
内に配置されているので、第６図に示すように、主構造
体５の幅が広くなり、ホーバークラフト１の重量増加の
原因になっているのみならず、点検修理などのメンテナ
ンスが面倒になる欠点がある。In addition, the floating fan 3 is attached to the main structure 5 of the hovercraft 1.
As shown in FIG. 6, the width of the main structure 5 becomes wide, which not only causes an increase in the weight of the hovercraft 1 but also makes maintenance such as inspection and repair troublesome. There are drawbacks.
本発明は、上記の如き、従来の欠点を解消すべく成され
たものであり、浮上ファンの吸引ロスを少なくしてファ
ン性能の向上を図ると共に、ホーバークラフトの重量軽
減を図り、かつ、点検修理等のメンテナンスを容易に行
えるようになしたことを目的とするものである。The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology, and aims to improve the fan performance by reducing the suction loss of the floating fan, reduce the weight of the hovercraft, and facilitate inspection and repair. The purpose of this is to make maintenance easier.
上記の目的を達成できる本発明の一つは浮上ファンを客
室前方の張出しデツキ上に配置したことに特徴があり、
他の発明は浮上ファンの吸引口をホーハークラフト前方
に向けて配置したことに特徴がある。One of the features of the present invention that can achieve the above object is that the floating fan is placed on the overhanging deck in front of the cabin.
Another feature of the invention is that the suction port of the floating fan is placed toward the front of the Hoha Craft.
以下、図面にしたがって本発明の実施例について説明す
る。Embodiments of the present invention will be described below with reference to the drawings.
第３図は本発明にかかるホーバークラフトの側面図、第
４図はその平面図であり、ホーバークラフト１１は、そ
の主構造体１５のほぼ中央に設けた客室１６の前方に前
部機関室１７を設けると共に、客室１６の後方に後部機
関室１８を備えている。FIG. 3 is a side view of the hovercraft according to the present invention, and FIG. 4 is a plan view thereof. The hovercraft 11 has a front engine room 17 in front of a passenger compartment 16 provided approximately in the center of its main structure 15. Additionally, a rear engine room 18 is provided at the rear of the passenger compartment 16.
前記後部機関室１８内に配設した推進機関１９によって
主構造体１５の後部に設けた推進プロペラ２０を回転す
るようになしている。この推進プロペラ２０の推進力に
よってホーバークラフト１１が前進することは言うまで
もない。A propulsion engine 19 disposed within the rear engine room 18 rotates a propulsion propeller 20 disposed at the rear of the main structure 15. Needless to say, the hovercraft 11 moves forward by the propulsive force of the propulsion propeller 20.
また、主構造体１５の後部に空中前２２を取りつけてい
る。そして、この空中前２２によってホーバークラフト
１１の進行方向が制御される。Further, an aerial front 22 is attached to the rear of the main structure 15. The moving direction of the hovercraft 11 is controlled by this aerial front 22.
前記主構造体１５の張出しデツキ２３の上に客室１６の
前方に位置して二つの浮上ファン１３．１３を配設する
。一方の浮上ファン１３は前部機関室１７の左舷側に設
けられ、他の一方の浮」二ファン１３は前部機関室１７
の右舷側に設けられる。Two floating fans 13.13 are disposed on the overhanging deck 23 of the main structure 15 in front of the cabin 16. One floating fan 13 is installed on the port side of the front engine room 17, and the other floating fan 13 is installed on the port side of the front engine room 17.
It is installed on the starboard side of the ship.
各浮上ファン１３は前記前部機関室１７内に設けた浮上
機関２４によって駆動される。浮上ファン１３には軸流
ファンを使用し、その軸心１４は、第１図に示すように
、ホーバークラフト１１の前方に向けられている。また
、各浮上ファン１３のダクト１３ａの吸入口２５は浮上
ファン１３の軸心１４と同様にホーバークラフト１１の
前方に向けられている。Each levitation fan 13 is driven by a levitation engine 24 provided in the front engine room 17. An axial fan is used as the floating fan 13, and its axis 14 is directed toward the front of the hovercraft 11, as shown in FIG. Further, the suction port 25 of the duct 13a of each floating fan 13 is directed toward the front of the hovercraft 11, similarly to the axis 14 of the floating fan 13.
このように、浮上ファン１３のダクＩ−１３ａの吸入口
２５をホーバークラフト１１の前方に向けると、ホーバ
ークラフト１１の前進中、ホーバークラフト１１の前進
に伴う動圧を吸収でき、浮上ファン１３の性能が従来の
ものに比べて格段に向上するようになる。In this way, when the suction port 25 of the duct I-13a of the levitation fan 13 is directed toward the front of the hovercraft 11, the dynamic pressure accompanying the forward movement of the hovercraft 11 can be absorbed while the hovercraft 11 is moving forward, and the performance of the levitation fan 13 is improved compared to the conventional one. It will be much improved compared to the previous one.
また、各浮上ファン１３のダクト１３ａに連通する誘導
管２６はフレキシブルスカート２７と主構造体１５の底
部２８によって囲まれた空気室２９に連通ずる。そして
、各浮上ファン１３がら空気室２９内に供給された空気
の圧力によってホーバークラフト１１が浮上する。The guide tube 26 communicating with the duct 13a of each floating fan 13 also communicates with an air chamber 29 surrounded by the flexible skirt 27 and the bottom 28 of the main structure 15. Then, the hovercraft 11 floats due to the pressure of the air supplied into the air chamber 29 from each levitation fan 13.
ところで、ダクト１３ａの吸入口２５をホーバークラフ
ト１１の前方に向ける場合、浮上ファン１３ば必ずしも
張出しデツキ２３上に設ける必要はなく、例えば、主構
造体１５内に設けてもよい。By the way, when the suction port 25 of the duct 13a is directed toward the front of the hovercraft 11, the floating fan 13 does not necessarily have to be provided on the overhanging deck 23, and may be provided inside the main structure 15, for example.
上記のように、本発明は、浮上ファンを客室前方の張出
しデツキ上に配置したので、浮上ファンの点検補修等の
メンテナンスが容易になると共に、主構造体の幅を狭く
でき、その分、主構造体を軽量化できる。As described above, in the present invention, the floating fan is placed on the overhanging deck in front of the cabin, so maintenance such as inspection and repair of the floating fan is facilitated, and the width of the main structure can be narrowed. The structure can be made lighter.
また、浮上ファンの前方に空気の吸入を遮るものがない
から浮上ファンの吸引ロスが少なくなり、ファンの性能
が格段に向上する。In addition, since there is nothing in front of the floating fan to block air intake, the suction loss of the floating fan is reduced, and the performance of the fan is significantly improved.
また、本発明は、浮上ファンの吸引口をホーバークラフ
ト前方に向けて配置したので、ホーバークラフトの前進
中は、ホーバークラフトの前進に伴う動圧を吸収でき、
その分、浮上ファンの性能が向上する。Furthermore, in the present invention, since the suction port of the floating fan is placed toward the front of the hovercraft, dynamic pressure accompanying the forward movement of the hovercraft can be absorbed while the hovercraft is moving forward.
The performance of the floating fan improves accordingly.
