Description

本発明は、飛行場を設けた船の構造に関し、更に詳しくは、従来の航空母艦と異なり、陸上飛行場に専ら使用される航空機を離着船できるようにした飛行場甲板と、前記飛行場甲板を支持する複数個の下部船体とからなる飛行場船に関する。 The present invention relates to a structure of a ship provided with an airfield, and more specifically, unlike a conventional aircraft carrier, an airfield deck capable of taking off and landing an aircraft exclusively used for a land airfield, and a plurality of airfield decks supporting the airfield deck It relates to an airfield ship consisting of a single lower hull.

従来の航空母艦は、武器弾薬のほか航空機昇降機や航空機格納庫等を設けるため、船体構造が複雑な上に、船体の長さが約３５０ｍ程度以下でなければ、旋回性能や推進性能が期待できず、また、航空機は蒸気カタパルや制動索等がなければ離着艦できない欠点があった。
また、従来の双胴船は、滑走距離の長い大型航空機を搭載することは、船体構造、旋回能力、推進能力等の欠点が予想されるので採用することができなかった。 In addition to weapons ammunition, conventional aircraft carriers are equipped with aircraft elevators, aircraft hangars, etc., so the hull structure is complicated and the turning performance and propulsion performance cannot be expected unless the hull length is about 350 m or less. In addition, the aircraft had the disadvantage that it could not be taken off and landing without a steam catapal or braking cable.
In addition, conventional catamaran cannot be used to install a large aircraft with a long run distance because defects such as hull structure, turning ability and propulsion ability are expected.

In consideration of the runway deck of the deck, the length of the runway deck can be greatly shortened. The standby road deck is provided on one side or both sides of the runway deck, but the length or width of the deck can be appropriately shortened.
Also, the uphill runway deck (including the ski jump deck) is formed on part or all of the deck, and the uphill angle is usually 5 It is provided within the range of the up-gradient angle of ° -15 °.

It does not include a mechanical pod propulsion device that rotates the propeller by mechanical transmission from an electric motor installed in the ship. Further, the pod can be rotated 360 degrees and does not include a non-rotating type.

本発明飛行場船は、下部船体毎にポッド推進器を設けているので、各下部船体のポッド推進器の一せい稼働によって、前進又は後進、旋回、横移動等の各能力が格段に優れ、向かい風に直ちに追尾して滑走路甲板の大型航空機の離着船距離の大幅な短縮、飛行場甲板の接岸が迅速にできるほか、前述のポッド推進器を使用するので、多数個の下部船体のうち、１個の下部船体に発電機を装備して、各下部船体のポッド推進器に飛行場甲板を介して配線送電するだけでよく、各下部船体の船体構造の簡略化による造船費の低減、少数乗員による操船が可能となり、維持費及び人件費等の大幅節減により充分な商業採算が可能となる。

本発明の飛行場船が実施例１に示されている。 An airfield ship of the present invention is shown in Example 1.

本発明飛行場船の実施例１が図１乃至図３−２に示されている。本発明実施例１の飛行場船は、飛行場甲板１０と、６個の下部船体２０と、６個のポッド推進器３０を備えている。
飛行場甲板１０は、全長１１００ｍ、幅６０ｍの滑走路甲板１０１と、その両側に連接した全長１１００ｍ、幅６０ｍの待機路甲板１０２及び１０２とを備えている。
各下部船体２０は、全長３００ｍ、幅２０ｍで、船尾に、ポッド推進器３０を設けている。
ポッド推進器３０は、いずれも１個の下部船体２０（１）の船内に設けたディーゼル機関又はガスタービン機関等の駆動機関により駆動される発電機（図示しない）が設けられて、図３−１に示すように、各下部船体２０のポッド推進器３０のポッド３１に送電されてポッド３１内の電動モーター（図示しない）の回転軸と直結して推進プロペラ３２を回転させることになる。各ポッド推進器３０は、下部船体２０に対し３６０°回転可能で、これにより各ポッド推進器３０の推進プロペラ３２は前進、後進、横移動等の全方位に推力を出せることになる。
なお、ポッド推進器３０には、図３−２に示すポッド３１の前後に推進プロペラ３２（１）及び３２（２）を設けて、それぞれ電動モーター３３（１）及び３３（２）の各回転軸に直結して下部船体２０（１）から送電してもよく、この場合は、機構複雑な二重反転プロペラ（ＣＲＰ）を使用することなく、推進プロペラ３２（１）及び３２（２）の互に反対方向の回転により、いわゆる回転流によるエネルギー損失を防止できる。
各下部船体２０は、約１００ｍの間隔に３個が直列配置されると共に、約１２０ｍの間隔で２列配置される。
従って、今、本発明飛行場船を、向かい風に対し追尾して３０ノットで推進し、滑走路甲板１０１が５°の上り勾配甲板１０１１の場合、離着陸滑走距離約１５００ｍ前後のＭ社やＢ社の双発ジェット旅客機程度ならば、全長１１００ｍの滑走路があれば充分離着船できることになる。また、横向き推進による接岸も迅速にできる。 A first embodiment of an airfield ship according to the present invention is shown in FIGS. 1 to 3-2. The airfield ship according to the first embodiment of the present invention includes an airfield deck 10, six lower hulls 20, and six pod thrusters 30.
The airfield deck 10 includes a runway deck 101 having a total length of 1100 m and a width of 60 m, and standby road decks 102 and 102 having a total length of 1100 m and a width of 60 m connected to both sides thereof.
Each lower hull 20 has a total length of 300 m and a width of 20 m, and is provided with a pod propulsion device 30 at the stern.
Each pod propulsion device 30 is provided with a generator (not shown) driven by a driving engine such as a diesel engine or a gas turbine engine provided in the ship of one lower hull 20 (1). As shown in FIG. 1, power is transmitted to the pod 31 of the pod propulsion device 30 of each lower hull 20 and directly connected to the rotation shaft of an electric motor (not shown) in the pod 31 to rotate the propeller propeller 32. Each pod propulsion device 30 can be rotated 360 ° with respect to the lower hull 20, so that the propeller 32 of each pod propulsion device 30 can generate thrust in all directions such as forward, reverse, and lateral movement.
The pod propulsion device 30 is provided with propulsion propellers 32 (1) and 32 (2) before and after the pod 31 shown in FIG. 3-2, and each rotation of the electric motors 33 (1) and 33 (2), respectively. The power may be transmitted from the lower hull 20 (1) directly connected to the shaft. In this case, the propulsion propellers 32 (1) and 32 (2) can be transmitted without using a complicated counter rotating propeller (CRP). By rotating in opposite directions, energy loss due to so-called rotational flow can be prevented.
Three lower hulls 20 are arranged in series at intervals of about 100 m, and two rows are arranged at intervals of about 120 m.
Therefore, now when the airfield ship of the present invention is tracked against the headwind and propelled at 30 knots, and the runway deck 101 is an uphill deck 1011 of 5 °, the takeoff and landing run distances of about 1500 m around M and B companies If it is about a twin-engine jet passenger aircraft, it will be possible to embark and depart on a runway with a total length of 1100m. In addition, berthing by sideways propulsion can be done quickly.

本発明飛行場船は、構造簡単で造船費安く量産できる。 The airfield ship of the present invention has a simple structure and can be mass-produced at a low shipbuilding cost.
