Description
本開示は垂直離着陸飛行体用吊り下げロープに関する。 The present disclosure relates to suspension ropes for vertical take-off and landing vehicles.
物体の落下、吊り下げ又は牽引等の際に生じる衝撃を吸収できなければ、重大な事故等につながることがある。例えば、落下としては人体や落石、吊り下げとしてはヘリコプターやドローン等の垂直離着陸飛行体、牽引としては故障車両等が挙げられる。 Failure to absorb the impact that occurs when an object is dropped, suspended, or towed may lead to serious accidents. For example, falling objects include human bodies and falling rocks, hanging objects include vertical take-off and landing aircraft such as helicopters and drones, and towing objects include broken vehicles.
ゴムやバネ等の高弾性ロープを用いてエネルギーの吸収を緩やかに行うと、例えば、人体であれば制動距離が長くなりすぎ、地面に激突したり、反動で壁に衝突したりすることがある。ヘリコプターやドローン等の垂直離着陸飛行体の吊り下げであれば吊り下げロープの伸縮振動の振幅が大きくて収まりにくく、機体が不安定になったり、機体制御のために過剰に燃料を消費したりすることがある。ヘリコプターやドローン等の垂直離着陸飛行体でこれを回避するには、吊り下げロープの伸縮振動を吸収するように精密に対応して振幅を減衰していく必要があり、高度な操縦技術を要する。 If a highly elastic rope such as rubber or spring is used to slowly absorb energy, for example, the braking distance becomes too long for the human body, and it may crash into the ground or collide with a wall due to recoil. . When suspending vertical take-off and landing aircraft such as helicopters and drones, the amplitude of the extension and contraction vibration of the suspension rope is large and difficult to settle, resulting in unstable aircraft and excessive fuel consumption for aircraft control. Sometimes. In order to avoid this with vertical take-off and landing aircraft such as helicopters and drones, it is necessary to respond precisely to absorb the stretching vibration of the suspension rope and attenuate the amplitude, which requires advanced maneuvering skills.
なお、理化学事典第５版は、「高弾性」を「一般に可逆弾性の限界（弾性限界）が大きい物質の弾性をいう。（中略）ほとんどの結晶性物質、固い合成樹脂などの弾性はこれに属さない（中略）高弾性をもつ物質の多くは高分子物質である」と記述する。本願明細書及び特許請求の範囲等では、「高弾性」は上記意味を有し、バネの弾性も含む。 The physics and chemistry encyclopedia 5th edition defines “high elasticity” as “generally the elasticity of substances with a large limit of reversible elasticity (elastic limit). Many of the substances that do not belong (omitted) and have high elasticity are polymeric substances.” In the specification and claims of the present application, "high elasticity" has the above meaning and includes the elasticity of the spring.
一方、低弾性（高弾性率）ロープを用いてエネルギーの吸収を速やかに行うと、衝撃が大きく、重大な事故等を防げないことがある。例えば、人体であれば命綱や安全ベルトの装着部での内臓破裂、ヘリコプターやドローン等の垂直離着陸飛行体であれば機体の不安定化や吊り下げロープの破断といったものが挙げられる。ヘリコプターやドローン等の垂直離着陸飛行体でこれを回避するには、低弾性（高弾性率）ロープに荷重がかかる直前に上昇速度を減速する必要があり、高度な操縦技術を要する。 On the other hand, if energy is rapidly absorbed using a low-elasticity (high-modulus) rope, the impact is large, and serious accidents may not be prevented. For example, in the case of the human body, visceral rupture at the attachment point of lifelines or safety belts, and in the case of vertical takeoff and landing aircraft such as helicopters and drones, there are destabilization of the aircraft and breakage of suspension ropes. In order to avoid this in vertical take-off and landing aircraft such as helicopters and drones, it is necessary to slow down the climb speed just before the load is applied to the low-elasticity (high-elasticity) rope, which requires advanced maneuvering skills.
これに対し、特許文献１は、第１のロープと、この第１のロープに並列に接続される第２のロープとを備え、前記第１のロープは、前記第２のロープに対する余長を有し、且つ、その余長が確保された状態で前記第２のロープが接続され、前記第２のロープは、前記第１のロープに較べて縦弾性係数が小さく且つ同じ長さで比較したときに、その破断に至る伸びしろが前記第１のロープに較べて長いエネルギー吸収型のロープであることを特徴とする衝撃吸収機構を開示する。特許文献１（００７３）は、また、エネルギー吸収ロープ５１を双方共に用いる衝突吸収機構５０を開示する。さらに、特許文献２は、第１～第Ｎ（Ｎは２以上の整数）の高弾性ロープを備え、第Ｋ（Ｋは１～Ｎの整数）の高弾性ロープの長さをＬＫとするとＬ１＜Ｌ２＜・・＜ＬＮであり、前記第１～第Ｎの高弾性ロープは、一端同士と他端同士がそれぞれ結合されて並列につながれ、第１～第Ｎ－１の高弾性ロープの各々の弾性限界での長さが第Ｎの高弾性ロープの長さ（ＬＮ）未満であることを特徴とする垂直離着陸飛行体用吊り下げロープを開示する。 On the other hand, Patent Document 1 includes a first rope and a second rope connected in parallel to the first rope, and the first rope has an extra length with respect to the second rope. and the second rope is connected in a state in which the extra length is secured, and the second rope has a smaller longitudinal elastic modulus than the first rope and has the same length. At times, a shock absorbing mechanism is disclosed which is characterized by an energy absorbing rope whose elongation before breakage is longer than said first rope. Patent Document 1 (0073) also discloses a crash absorbing mechanism 50 that uses both energy absorbing ropes 51 . Furthermore, Patent Document 2 includes 1st to Nth (N is an integer of 2 or more) high-elasticity ropes, and if the length of the Kth (K is an integer of 1 to N) high-elasticity rope is LK, then L 1 < L 2 < . Disclosed is a suspension rope for a vertical take-off and landing vehicle, wherein the length of each rope at its elastic limit is less than the length (L N ) of the Nth high-elasticity rope.
特許文献１は、エネルギー量の最も高い衝突初期における衝突エネルギーを、エネルギー吸収型の第２のロープで吸収した後、残りのエネルギーを第１のロープで吸収する。しかし、特許文献１は、近隣の道路等に対する落石を防止するため、第１のロープには汎用鋼製ロープを用いる。したがって、鋼製の第１のロープに荷重がかかると、一気に衝撃がかかり、重大な事故等を防げないことがある。例えば、人体であれば命綱や安全ベルトの装着部での内臓破裂、ヘリコプターやドローン等の垂直離着陸飛行体であれば機体の不安定化や吊り下げロープの破断といったものが挙げられる。ヘリコプターやドローン等の垂直離着陸飛行体でこれを回避するには、第１のロープに荷重がかかる直前に上昇速度を減速する必要があり、高度な操縦技術を要する。また、特許文献１の衝撃吸収機構５０は落石防止用であり、垂直離着陸飛行体の吊り下げロープに用いることについて記載も示唆もない。 In Patent Document 1, after the collision energy at the initial stage of collision with the highest amount of energy is absorbed by the energy absorbing second rope, the remaining energy is absorbed by the first rope. However, Patent Document 1 uses a general-purpose steel rope as the first rope in order to prevent falling rocks onto nearby roads and the like. Therefore, when a load is applied to the first steel rope, the impact is applied all at once, and a serious accident or the like may not be prevented. For example, in the case of the human body, visceral rupture at the attachment point of lifelines or safety belts, and in the case of vertical takeoff and landing aircraft such as helicopters and drones, there are destabilization of the aircraft and breakage of suspension ropes. In order to avoid this in vertical take-off and landing aircraft such as helicopters and drones, it is necessary to decelerate the climb speed immediately before the load is applied to the first rope, which requires advanced maneuvering skills. Further, the shock absorbing mechanism 50 of Patent Document 1 is for preventing falling rocks, and there is no description or suggestion about using it for a suspension rope of a vertical take-off and landing aircraft.
特許文献２は、第Ｎの高弾性ロープに荷重がかかる前に第１～Ｋ－１の高弾性ロープが弾性限界に至るため、第１～Ｋ－１の高弾性ロープに急激な荷重がかかり、エネルギー吸収がスムーズかつ十分に行えない。場合によっては第１～Ｋ－１の高弾性ロープが切断することがある。ヘリコプターやドローン等の垂直離着陸飛行体でこれを確実に回避するには、第Ｎの高弾性ロープに荷重がかかる前に上昇速度を減速する必要があり、高度な操縦技術を要する。 In Patent Document 2, since the 1st to K-1 high-elasticity ropes reach the elastic limit before the load is applied to the Nth high-elasticity rope, a sudden load is applied to the 1st to K-1 high-elasticity ropes. , energy absorption cannot be performed smoothly and sufficiently. In some cases, the 1st to K-1 highly elastic ropes may break. In order to reliably avoid this in vertical take-off and landing aircraft such as helicopters and drones, it is necessary to decelerate the climb speed before the load is applied to the Nth highly elastic rope, which requires advanced maneuvering skills.
本開示は上記実状を鑑みてなされたものであり、本開示の目的は、衝撃が一気にかかることなく、エネルギー吸収を漸増かつ迅速に行うことにより、重大な事故等を防ぐことができる垂直離着陸飛行体用吊り下げロープを提供することである。 The present disclosure has been made in view of the above-mentioned actual situation, and the purpose of the present disclosure is to provide a vertical take-off and landing flight that can prevent serious accidents by gradually increasing and quickly absorbing energy without applying a shock all at once. To provide a body suspension rope.

本開示の垂直離着陸飛行体用吊り下げロープの引っ張り方向に衝撃が加わると、第Ｋ（Ｋは１～Ｎの整数）の高弾性ロープの長さＬＫはＬ１＜Ｌ２＜・・＜ＬＮであり、第１～第Ｎの高弾性ロープは、一端同士と他端同士がそれぞれ結合されて並列につながれているため、最も短い第１の高弾性ロープから順に荷重がかかり、それぞれの高弾性ロープでエネルギー吸収が開始される。第１～第Ｎ－１の高弾性ロープの各々の弾性限界での長さが第Ｎの高弾性ロープの長さ（ＬＮ）以上であるため、第１～第Ｎの高弾性ロープの全てが順次エネルギー吸収に参加する。その結果、エネルギー吸収を漸増かつ迅速に行うことができ、衝撃が一気にかかることない。また、本開示の垂直離着陸飛行体用吊り下げロープは構造が簡単なため、低コストで製造することができる。さらに、本開示の垂直離着陸飛行体用吊り下げロープをヘリコプターやドローン等の垂直離着陸飛行体の吊り下げロープに用いると、吊り下げロープの弾性率が漸増するため、伸縮振動の振幅が小さく、かつ、収まりやすい。その結果、吊り下げロープに荷重がかかる直前に機体の上昇速度を減速したり、吊り下げロープの伸縮振動を吸収するように精密に対応したりする必要がなく、高度な操縦技術を要さない。 When an impact is applied in the pulling direction of the suspension rope for a vertical take-off and landing aircraft of the present disclosure, the length of the K-th (K is an integer of 1 to N) high-elasticity rope L K is L 1 < L 2 < . L N , and the first to Nth high-elasticity ropes are connected at one end and the other end and connected in parallel, so the load is applied in order from the shortest first high-elasticity rope, and each Energy absorption starts with high elastic ropes. Since the length at the elastic limit of each of the 1st to N-1th high-elasticity ropes is equal to or greater than the length of the Nth high-elasticity rope (L N ), all of the 1st to Nth high-elasticity ropes sequentially participate in energy absorption. As a result, the energy absorption can be gradually increased and rapidly, and the impact is not applied all at once. In addition, the suspension rope for vertical take-off and landing aircraft of the present disclosure has a simple structure and can be manufactured at a low cost. Furthermore, when the suspension rope for vertical takeoff and landing aircraft of the present disclosure is used as a suspension rope for vertical takeoff and landing aircraft such as helicopters and drones, the elastic modulus of the suspension rope gradually increases, so the amplitude of stretching vibration is small and , easy to fit. As a result, there is no need to decelerate the fuselage's ascending speed immediately before the load is applied to the suspension rope, or to take precise measures to absorb the extension and contraction vibration of the suspension rope. .

Deterioration of the first to Nth high-elasticity ropes can be prevented by providing the stretchable cover for covering the first to Nth high-elasticity ropes. In addition, since a plurality of high-elasticity ropes can be integrated together, handling is facilitated.
