発明を実施するための好ましい形態Preferred form for carrying out the invention

以下、本発明の好ましい形態を図面により説明するが、本発明の範囲はこれらの形態に限定されるものではない。   Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings, but the scope of the present invention is not limited to these embodiments.

図１は、本発明の小型推力発生装置の一実施形態を示す断面図である。この実施形態の小型推力発生装置１は、半導体電橋１３から発生するプラズマによって推力を得て矢印Ａ方向に飛翔するものである。推力発生装置１の金属の円筒１２に蓋を兼ねたセラミックの基板１４が取り付けられる。セラミック基板１４上であって円筒１２の内部空間に５mm程度の大きさのプラズマ発生半導体電橋１３が形成される。半導体電橋１３からは電極ピン１５が伸びており、リード線およびスイッチング回路を（図示省略）を介して電源、例えば太陽電池に繋がる。推力発生装置１は、例えば人工衛星などの宇宙航行体２に連結されている。尚、円筒の材質はガラス、樹脂、あるいはセラミックであってもよい。   FIG. 1 is a cross-sectional view showing an embodiment of the small thrust generator of the present invention. The small thrust generator 1 according to this embodiment obtains a thrust by plasma generated from the semiconductor bridge 13 and flies in the direction of arrow A. A ceramic substrate 14 also serving as a lid is attached to the metal cylinder 12 of the thrust generator 1. A plasma generating semiconductor bridge 13 having a size of about 5 mm is formed in the internal space of the cylinder 12 on the ceramic substrate 14. An electrode pin 15 extends from the semiconductor bridge 13 and connects the lead wire and the switching circuit to a power source, for example, a solar cell, through a not-shown. The thrust generator 1 is connected to a spacecraft 2 such as an artificial satellite. The material of the cylinder may be glass, resin, or ceramic.

宇宙に存在するこの小型推力発生装置１のスイッチング回路をオンにして電源から半導体電橋１３に電圧を印加し通電すると、プラズマが発生し、円筒１２の空間を通って矢印Ｂ方向に噴射する。これにより推力を得て宇宙航行体２は矢印Ａ方向に飛翔する。通電電流の大きさにより、出力するプラズマ量が変わるため、電流値を変えることにより、目的の推力の微量調整ができる。   When the switching circuit of the small thrust generator 1 existing in the universe is turned on and a voltage is applied from the power source to the semiconductor bridge 13 and energized, plasma is generated and injected through the space of the cylinder 12 in the direction of arrow B. As a result, thrust is obtained and the spacecraft 2 flies in the direction of arrow A. Since the amount of plasma to be output changes depending on the magnitude of the energization current, the target thrust can be finely adjusted by changing the current value.

図２は、本発明の小型推力発生装置の別な一実施形態を示す断面図である。この実施形態の推力発生装置３は、推進薬５によって推力を得て矢印Ａ方向に飛翔するものである。推力発生装置３の円筒１２に蓋を兼ねた基板１４が取り付けられる。基板１４上であって円筒１２の内部にプラズマ発生半導体電橋１３が形成され、円筒１２の残余の内部に推進薬５が充填される。推進薬５は、硝酸塩と金属を主とする火薬（例えばボロン／硝酸カリウム）や塩素酸塩と金属を主とする火薬（例えばロダン鉛／塩素酸カリウム）が使用できる。半導体電橋１３からは電極ピン１５が伸びており、リード線およびスイッチング回路を介して電源に繋がる。小型推力発生装置１は、宇宙航行体に連結される。   FIG. 2 is a cross-sectional view showing another embodiment of the small thrust generator of the present invention. The thrust generator 3 of this embodiment obtains thrust by the propellant 5 and flies in the direction of arrow A. A substrate 14 also serving as a lid is attached to the cylinder 12 of the thrust generator 3. A plasma generating semiconductor bridge 13 is formed on the substrate 14 and inside the cylinder 12, and the remaining part of the cylinder 12 is filled with the propellant 5. As the propellant 5, explosives mainly composed of nitrate and metal (for example, boron / potassium nitrate) and explosives mainly composed of chlorate and metal (for example, rhodium lead / potassium chlorate) can be used. An electrode pin 15 extends from the semiconductor bridge 13 and is connected to a power source via a lead wire and a switching circuit. The small thrust generator 1 is connected to a spacecraft.

宇宙空間に存在するこの小型推力発生装置３のスイッチング回路をオンにして電源から半導体電橋１３に電圧を印加し通電するとプラズマが発生し、プラズマが発生して推進薬５を点火する。すると、推進薬５から気体が矢印Ｂ方向に噴射することで推力を得て宇宙航行体は矢印Ａ方向に飛翔する。推進薬５の量を変えることにより、目的の推力に調整できる。   When the switching circuit of the small thrust generator 3 existing in outer space is turned on and a voltage is applied from the power source to the semiconductor bridge 13 to energize it, plasma is generated and plasma is generated to ignite the propellant 5. Then, a propellant 5 jets gas in the direction of arrow B to obtain thrust, and the spacecraft flies in the direction of arrow A. The target thrust can be adjusted by changing the amount of the propellant 5.

図３は、本発明の小型推力発生装置のさらに別な一実施形態を示す断面図である。この実施形態の推力発生装置４は、矢印Ｄ方向に飛翔するものである。推力発生装置４の円筒１２にシリコンの基板２４が取り付けられ、基板２４上であって円筒１２の内部にプラズマ発生半導体電橋１３が形成される。同じく基板２４の裏側には、スリーブ１７が取り付けられ、中央に噴射ノズルが形成される。   FIG. 3 is a cross-sectional view showing still another embodiment of the small thrust generator of the present invention. The thrust generator 4 of this embodiment flies in the direction of arrow D. A silicon substrate 24 is attached to the cylinder 12 of the thrust generator 4, and a plasma generating semiconductor bridge 13 is formed on the substrate 24 and inside the cylinder 12. Similarly, a sleeve 17 is attached to the back side of the substrate 24, and an injection nozzle is formed at the center.

円筒１２のシリコン基板２４とは反対側には金属の蓋２５が密封して固着される。半導体電橋１３からは電極ピン１５が基板２４を通って伸びており、リード線およびスイッチング回路を介して電源に繋がる。推力発生装置４は、蓋２５側で宇宙航行体２に連結される。尚、基板は、シリコンの他、ガラス、樹脂、薄いセラミックなど衝撃により破損する材質が使える。   On the opposite side of the cylinder 12 from the silicon substrate 24, a metal lid 25 is hermetically sealed. An electrode pin 15 extends from the semiconductor bridge 13 through the substrate 24 and is connected to a power source via a lead wire and a switching circuit. The thrust generator 4 is connected to the spacecraft 2 on the lid 25 side. In addition to silicon, the substrate can be made of a material that is damaged by impact, such as glass, resin, or thin ceramic.

宇宙空間に存在するこの小型推力発生装置４のスイッチング回路をオンにして電源から半導体電橋１３に電圧を印加し通電するとプラズマが発生する。その衝撃により基板２４が破損し（鎖線参照）、ノズルからプラズマが矢印Ｅ方向に噴射して推力を得、宇宙航行体２は矢印Ｄ方向に飛翔する。   When the switching circuit of the small thrust generator 4 existing in outer space is turned on and a voltage is applied from the power source to the semiconductor bridge 13 and energized, plasma is generated. The substrate 24 is damaged by the impact (see the chain line), plasma is ejected from the nozzle in the direction of arrow E to obtain thrust, and the spacecraft 2 flies in the direction of arrow D.

この実施の形態の推力発生装置４は、プラズマが発生したとき蓋２５と基板２４の密閉によって円筒１２の内圧が上がり、基板２４の破損によりプラズマが一気に噴出して大きな推力を得ることが可能となる。   In the thrust generator 4 of this embodiment, when the plasma is generated, the internal pressure of the cylinder 12 increases due to the sealing of the lid 25 and the substrate 24, and the plasma is blown out at a stroke due to the damage of the substrate 24, thereby obtaining a large thrust. Become.

図４は、本発明の小型推力発生装置のさらに別な一実施形態を示す断面図である。この実施形態の推力発生装置６は、矢印Ｄ方向に飛翔するものである。推力発生装置６の円筒１２にガラスの基板２６が取り付けられ、基板２６上であって円筒１２の内部にプラズマ発生半導体電橋１３が形成される。円筒１２の残余の内部に推進薬５が充填される。半導体電橋１３からは電極ピン１５が基板２６を通って伸びており、リード線およびスイッチング回路を介して電源に繋がる。同じく基板２６の裏側には、スリーブ１７が取り付けられ、中央に噴射ノズルが形成される。   FIG. 4 is a cross-sectional view showing still another embodiment of the small thrust generator of the present invention. The thrust generator 6 of this embodiment flies in the direction of arrow D. A glass substrate 26 is attached to the cylinder 12 of the thrust generator 6, and a plasma generating semiconductor bridge 13 is formed on the substrate 26 and inside the cylinder 12. The remaining portion of the cylinder 12 is filled with the propellant 5. Electrode pins 15 extend from the semiconductor bridge 13 through the substrate 26 and are connected to a power source through lead wires and a switching circuit. Similarly, a sleeve 17 is attached to the back side of the substrate 26, and an injection nozzle is formed at the center.

円筒１２の基板２６とは反対側には蓋２５が密封して固着される。推力発生装置６は、蓋２５側で宇宙航行体２に連結される。   A lid 25 is sealed and fixed to the opposite side of the cylinder 12 from the substrate 26. The thrust generator 6 is connected to the spacecraft 2 on the lid 25 side.

宇宙空間に存在するこの小型推力発生装置６のスイッチング回路をオンにして電源から半導体電橋１３に電圧を印加し通電するとプラズマが発生して推進薬５を点火する。その衝撃により基板２６が破損し（鎖線参照）、推進薬５から気体が矢印Ｅ方向に噴射することで推力を得て宇宙航行体は矢印Ｄ方向に飛翔する。   When the switching circuit of the small thrust generator 6 existing in outer space is turned on and a voltage is applied from the power source to the semiconductor bridge 13 and energized, plasma is generated and the propellant 5 is ignited. The substrate 26 is broken by the impact (refer to the chain line), and the spacecraft flies in the direction of the arrow D by obtaining a thrust when the gas is injected from the propellant 5 in the direction of the arrow E.

図５は、本発明の小型推力発生装置のさらに別な一実施形態を示す斜視図である。この実施形態の推力発生装置１０は、プリント基板２１上に個別の推力発生装置１１の多数のアレイを設置したもので、宇宙航行体２が連結されている。   FIG. 5 is a perspective view showing still another embodiment of the small thrust generator of the present invention. The thrust generation device 10 of this embodiment is configured by installing a large number of individual thrust generation devices 11 on a printed circuit board 21, and the spacecraft 2 is connected thereto.

個別の推力発生装置１１は、図６の断面図に示すとおり、プリント基板２１上に配置された円筒１２の内部にプラズマ発生半導体電橋１３が形成されている。各プラズマ発生半導体電橋１３どうしは、プリント基板２１の配線２３に連結している。プリント配線２３は、スイッチング回路、制御回路を介して電源に繋がる。   As shown in the sectional view of FIG. 6, the individual thrust generator 11 has a plasma generating semiconductor bridge 13 formed inside a cylinder 12 arranged on a printed circuit board 21. The plasma generating semiconductor bridges 13 are connected to the wiring 23 of the printed board 21. The printed wiring 23 is connected to a power source via a switching circuit and a control circuit.

宇宙に存在するこの小型推力発生装置１０のスイッチング回路をオンにして電源から半導体電橋１３に電圧を印加し通電すると、プラズマが発生し、円筒１２の空間を通って矢印Ｂ方向に噴射する。このとき、制御回路によりプリント配線の通電を制御することで、推力の方向を変えることができる。例えば推力発生装置１１のアレイのうち右一列を作動させると左に旋回し、所望の角度の旋回ができたら、他の推力発生装置１１を作動させれば、以後、直進する。   When the switching circuit of the small thrust generator 10 existing in space is turned on and a voltage is applied from the power source to the semiconductor bridge 13 and energized, plasma is generated and injected through the space of the cylinder 12 in the direction of arrow B. At this time, the direction of the thrust can be changed by controlling the energization of the printed wiring by the control circuit. For example, when the right row of the array of thrust generators 11 is operated, the vehicle turns to the left, and when a desired angle of rotation is achieved, the other thrust generators 11 are operated, and then the vehicle travels straight.

図５、図６の推力発生装置で、円筒１２の残余の内部に推進薬５を充填し、図２、図４に示したような作動をすることもできる。   5 and 6, the remaining portion of the cylinder 12 can be filled with the propellant 5 and the operation shown in FIGS. 2 and 4 can be performed.

図７は、本発明の小型推力発生装置のさらに別な一実施形態を示す断面図である。この実施形態の推力発生装置９は、プラスチックのプリント基板２９上に個別の推力発生装置９の多数のアレイを設置し、内部にプラズマ発生半導体電橋１３が形成される円筒１２が蓋板２８で塞がれる。各プラズマ発生半導体電橋１３どうしは、プリント基板２９の配線２３に連結している。プリント基板２９の裏側には、個別の推力発生装置９に対応する位置にスリーブ１７が取り付けられてスリーブ１７の中央に噴射ノズルが形成される。蓋板２８に宇宙航行体２が連結している。   FIG. 7 is a cross-sectional view showing still another embodiment of the small thrust generator of the present invention. In this embodiment, the thrust generator 9 is provided with a large number of arrays of individual thrust generators 9 on a plastic printed board 29, and a cylinder 12 in which a plasma generating semiconductor bridge 13 is formed is a lid plate 28. It is blocked. The plasma generating semiconductor bridges 13 are connected to the wiring 23 of the printed circuit board 29. On the back side of the printed circuit board 29, a sleeve 17 is attached at a position corresponding to the individual thrust generating device 9, and an injection nozzle is formed at the center of the sleeve 17. The spacecraft 2 is connected to the cover plate 28.

宇宙に存在するこの小型推力発生装置のスイッチング回路をオンにして電源から半導体電橋１３に電圧を印加し通電すると、プラズマが発生し、その衝撃によりプラスチックの基板２９が破損し（鎖線参照）、ノズルからプラズマが矢印Ｅ方向に噴射して宇宙航行体２は矢印Ｄ方向に飛翔する。   When the switching circuit of this small thrust generator existing in space is turned on and a voltage is applied from the power source to the semiconductor bridge 13 and energized, plasma is generated, and the plastic substrate 29 is damaged by the impact (see the chain line). Plasma is ejected from the nozzle in the direction of arrow E, and the spacecraft 2 flies in the direction of arrow D.
