【産業上の利用分野】
本発明は航空機がエンジン故障、車輪が出ないための胴体着陸、尾翼の操舵不能の故障による山岳への衝突、火災事故又は爆発事故など種種の原因により航空機が不時着を余儀なくされる事態に陥った時に、エンジンを停止し、機首、機体中央部、機体後部の3ケ所に装着された落下傘を放出し、開くことによって機体の落下速度を小さくし、軟着陸させることができる救援設備に関するものである。
さらに、本発明はエンジン故障、火災などのために航空機が海上或いは湖水上に墜落又は不時着するような事態に陥った時、胴体下部及び主翼下部に装着してあったガスバッグに、機内に搭載されていたヘリウムガスボンベ内のヘリウムガスを充填し、その浮力で航空機が水上に浮かんでいられるようにする救援設備に関するものである。
【0002】
【従来の技術】
航空機の車輪が出なくなって飛行場へ胴体着陸しなければならなくなった際に滑走路近くに設置した貯水タンクの水を一気に滑走路に流すことによって、航空機の胴体に対するショックを緩和し、安全に胴体着陸すことを可能にしようという特開平11−139399がある。
又、航空機が胴体着陸しようとする時に、大きなエアバッグを積んだ台車を滑走路上を走らせ、航空機をこのエアバッグの上に着陸させることによって胴体着陸の危険を回避しようという特開平10−305800のような従来技術がある。
これらの安全に胴体着陸させようという技術は貯水タンク、台車を備えている飛行場に胴体着陸する場合に限られていて、飛行場以外の平坦地、又は丘陵山岳地帯に墜落或るいは不時着する際の救援には役立たない。
航空機が海又は湖の上を飛行している際、エンジンの故障、火災、爆発事故その他の原因によって水上に墜落或るいは不時着する場合の対策としては、旅客機などでは各人が直ぐに利用できる救命胴衣を用意しており、航空機が水面に着水すれば、乗客、乗員は救命胴衣つけて機外に脱出し、救援の船舶または飛行機が到着するまで水面に浮かんでいられるようにする対策しか用意されていない。従って冬季水温が10°C以下の時に遭難者が生存し得る確率は極めて低いのが現状である。
【0003】
【発明が解決しようとする課題】
航空機はラジオ、テレビ、コンピューターと並んで20世紀に入ってから人類が実現した大発明の一つであり、地球上で最高速の交通、輸送機関となり、特に大型ジェット機の就航によって大量、高速輸送が可能になったが、航空機が空中を飛行するという特性上、一旦墜落事故が起ると燃料に引火して起こる火災、爆発を併発し、一瞬にして多数の人命が失われるという危険を内蔵している。陸上及び水上への航空機の不時着の被害を軽減し、安全性を高めることは、人類の悲願であり、極めて大きな課題である。
【0004】
【課題を解決するための手段】
本発明は航空機が何らかの原因によって地上に墜落或るいは不時着を余儀なくされる事態に際して、機首、機体中央及び機体後部の3ケ所に装着された落下傘を放出し、開かせると共に機体下部及び主翼下部に具えたガスバツグにヘリウムガスを充填することによって機体の落下速度を小さくし、軟着陸することを可能にする。
さらに本発明は海又は湖などの水上で航空機が墜落又は不時着せざるを得ない緊急時に、主翼の下面又は機体下面に装着してあったガスバッグに機内に搭載されてあったヘリウムガスボンベからヘリウムスを送りこんでガスバッグを膨脹させ、その浮力で救援の航空機或るいは船舶が到着するまで航空機が水面上に浮かんでいることを可能にする。
【0005】
【作用】
本発明は上記の手段を講ずることによって、陸上或いは水上で航空機が墜落又は不時着せざるを得ない非常事態に際しては落下傘を開き、機体下部及び主翼下部に設けたガスバッグにヘリウムガスを送りこんで膨脹させ、それらの浮力によって落下速度を小さくして軟着陸{軟着水}することを可能にし、水面に着水してからはガスバッグの浮力によって航空機が水面に浮かんでいられる事を可能にする。
航空機の事故の80%は離陸、着陸の際に発生するといわれている。航空機が離陸する際には推力の大きさと機体の抵抗が計算通りならば、必要滑走路の60%から75%ぐらい滑走したところでV{最大離陸断念速度}に達する。この速度に達する前にエンジンに故障が発生すれば、直ちに停止、着陸操作を行う。。
ところがVに達して離陸姿勢に入ってからエンジンに故障が発生し、推力が不足すると航空機は失速し、墜落事故を起こすことになる。このような場合、直ちに落下傘を放出し、落下速度を小さくすれば失速、墜落、火災発生といった事故を防ぐことができる。
本発明によれば、陸上で墜落又は不時着するといった事故に際してはエンジンを停止すると同時に落下傘を開くと共にガスバッグにヘりウムガスを充填することによって落下速度を減少し、軟着陸させて事故を未然に防ぎ、航空機が水上に墜落、不時着せざるを得ない時には、ガスバッグにヘリウムガスを送りこんでその浮力によって航空機が水上に浮かんでいられるようにし、墜落、不時着事故により多数の人命が失われるという航空機の最大の弱点を軽減又は解消することができ、今後の航空機の運用に多大の利点をもたらす事ができる。
【0006】
【実施例1】航空機の機首の落下傘収納室1、航空機中央の落下傘収納室2、航空機後部の落下傘収納室3には落下傘4、5、6が収納されている。
航空機が飛行不能、墜落せざるを得ないといった緊急事態には収納室の扉7、8、9が開き、落下傘4、5、6は収納室1、2、3から空中に放出れ、開くことによって落下傘の浮力によって航空機が滑空状態から急激に落下状態におちいることを防ぎ、航空機が地上或るいは水面上に軟着陸することを可能にする。
「実施例2」航空機が地上或いは水上に墜落、不時着せざるを得ない緊急事態に陥った時には、航空機の機体下面に装着されているガスバッグ10、11および主翼下面に装着されているガスバッグ13、14にヘリウムガスを送り込んで膨張させ、その浮力によって航空機の落下速度を減衰させ、航空機が地面或いは水面に激突することを防ぎ、軟着陸(着水)することを可能にする。
【実施例3】航空機が水上に墜落、不時着せざるを得ない緊急事態におちいった時、航空機の機体下面に装着されているガスバッグ11、12及び主翼の下面に装着されているガスバッグ13、14にヘリウムガスを送りこんで膨脹させ、その浮力によって着水した航空機が水上に浮かんでいられることを可能にする。

[Industrial applications]
According to the present invention, the aircraft is forced to land accidentally due to various causes such as an engine failure, a fuselage landing due to a wheel not coming out, a failure to steer the tail wing, a collision with a mountain, a fire accident or an explosion accident. The present invention relates to a rescue facility that sometimes stops an engine, releases parachute attached to three places of a nose, a center part of a fuselage, and a rear part of a fuselage, and opens the parachute to reduce a falling speed of the fuselage and make a soft landing. .
Further, when the aircraft crashes on the sea or lake or crashes due to engine failure, fire, etc., the gas bag attached to the lower fuselage and the lower wing is installed in the aircraft. The present invention relates to a rescue facility that fills a helium gas in a helium gas cylinder that has been filled and allows the aircraft to float on the water by its buoyancy.
[0002]
[Prior art]
When the aircraft's wheels stop coming out and the fuselage needs to land at the airfield, the water in the water storage tank installed near the runway is flushed to the runway to mitigate shocks to the aircraft's fuselage and secure the fuselage safely. There is Japanese Patent Application Laid-Open No. Hei 11-139399 that makes it possible to land.
Also, when an aircraft attempts to land on the fuselage, a truck carrying a large airbag is run on the runway, and the danger of landing on the fuselage is avoided by landing the aircraft on the airbag. There is such a prior art.
These techniques for safely landing the fuselage are limited to the case where the fuselage lands on an airfield equipped with a water tank and a bogie, and when landing or crash landing on flat terrain other than the airfield or on a hilly mountainous area. Useless for rescue.
As a countermeasure for aircraft crashing or landing on water due to engine failure, fire, explosion, or any other cause while the aircraft is flying over the sea or lake, passengers and other passengers can immediately use lifesaving Jackets are provided, and if the aircraft lands on the water, passengers and crew can wear a life jacket and escape outside the aircraft, so that they can float on the surface until the rescue ship or airplane arrives. Not prepared. Therefore, the probability that survivors can survive when the winter water temperature is 10 ° C. or lower is extremely low at present.
[0003]
[Problems to be solved by the invention]
Aircraft, along with radios, televisions and computers, is one of the great inventions that humanity has realized since the beginning of the 20th century. It has become the fastest transportation and transportation system on the planet, especially in large-volume and high-speed transportation with the introduction of large jet aircraft. However, due to the characteristics of aircraft flying in the air, once a crash occurs, the fuel ignites the fuel, causing fire and explosion, and the risk that many human lives are lost in an instant are doing. Reducing the impact of accidental landings of aircraft on land and water and increasing safety is a human race's longing and a huge challenge.
[0004]
[Means for Solving the Problems]
The present invention releases the parachute attached to the nose, the center of the fuselage, and the rear part of the fuselage in the event that the aircraft crashes or crashes to the ground for some reason, causes the parachute to be opened, and opens the lower fuselage and the lower wing. By filling the gas bag equipped with the helium gas with the helium gas, it is possible to reduce the falling speed of the airframe and to make a soft landing.
Further, the present invention relates to a helium gas from a helium gas cylinder mounted on a gas bag mounted on the lower surface of a wing or a lower surface of an aircraft in an emergency when an aircraft has to be crashed or emergency landing on water such as the sea or a lake. To inflate the gas bag, and its buoyancy allows the aircraft to remain above the surface of the water until the rescue aircraft or vessel arrives.
[0005]
[Action]
By taking the above measures, the present invention opens the parachute in the event of an aircraft crash or emergency landing on land or in the water, and sends helium gas to the gas bag provided in the lower part of the fuselage and the lower part of the main wing to expand it. The buoyancy reduces the falling speed and enables soft landing (soft landing), and after landing on the water surface, the buoyancy of the gas bag allows the aircraft to float on the water surface. .
It is said that 80% of aircraft accidents occur during takeoff and landing. If the size and resistance as calculated for aircraft thrust when the aircraft takes off, reaches V 1 {maximum takeoff abandon rates} where skate about 75% to 60% of the required runway. If the engine fails before reaching this speed, stop and land immediately. .
However, failure of the engine is generated since the beginning of the take-off attitude reached V 1, when the thrust is insufficient aircraft to stall, so that the cause of the crash. In such a case, if the parachute is immediately released and the falling speed is reduced, accidents such as stall, fall, and fire can be prevented.
According to the present invention, in the event of an accident such as a crash or accident landing on land, the engine is stopped and the parachute is opened and the gas bag is filled with helium gas to reduce the falling speed and prevent the accident by soft landing. In the event that an aircraft crashes on the water and must be brought into emergency, helium gas is sent into the gas bag to allow the aircraft to float on the water due to its buoyancy, and a large number of lives are lost due to the crash or accidental landing. The greatest weakness of the aircraft can be reduced or eliminated, which can bring great advantages to future operation of the aircraft.
[0006]
Embodiment 1 Parachutes 4, 5, and 6 are stored in a parachute storage room 1 at the nose of an aircraft, a parachute storage room 2 at the center of the aircraft, and a parachute storage room 3 at the rear of the aircraft.
In emergency situations, such as when the aircraft cannot fly or has to crash, the storage compartment doors 7, 8, 9 open, and the parachute 4, 5, 6 is released from storage compartments 1, 2, 3 into the air and opened. The buoyancy of the parachute prevents the aircraft from falling suddenly from a gliding state and allows the aircraft to land softly on the ground or on the water.
[Example 2] When an aircraft crashes on the ground or on the water and has to be brought into emergency, the gas bags 10, 11 mounted on the lower surface of the aircraft and the gas bags mounted on the lower surface of the wing of the aircraft are required. The helium gas is fed into the hulls 13 and 14 to expand them, and the buoyancy of the helium gas reduces the falling speed of the aircraft, prevents the aircraft from colliding with the ground or the water surface, and enables soft landing (landing).
Embodiment 3 When an aircraft crashes on the water and falls into an emergency in which it must be put on emergency, the gas bags 11 and 12 mounted on the lower surface of the aircraft body and the gas bag 13 mounted on the lower surface of the main wing are provided. , 14 are inflated by injecting helium gas, the buoyancy of which allows the landed aircraft to float above the water.
