Definitions
- the present invention opens a parachute when a person jumps from a flying aircraft, drops an object, drops it, or when the aircraft itself loses balance and falls, regardless of descent speed or altitude position. It is a parachute that allows for a stable descent.
- the opening of a parachute In the air, the opening of a parachute, represented by the hemispherical type currently used, first opens the parachute for a small pilot in the air, then discharges and pulls the parachute out of the storage bag using the wind pressure of the descent. It opens using the power of the wind on the bottom.
- the parachute and the aircraft When jumping directly from the aircraft, the parachute and the aircraft are temporarily tied and pulled out of the storage bag, and then the bar is opened in a rod-like manner by applying wind pressure to the lower part of the parachute. Furthermore, the maximum load is generated at a stretch when the umbrella is opened due to its shape and usage.
- opening a parachute required speed pressure required for it and a descent distance to generate it. And it was impossible to change the descent speed or reduce the load when opening the umbrella. Furthermore, there was no way to reduce the impact force generated at the time of landing, and there was no choice but to rely on the buoyancy of falling objects when landing on the water.
- the parachute according to the present invention When opened, the parachute according to the present invention has a truncated conical shape, that is, a wing of a battledore and a shuttle of badminton, and the main body is made of a thin membrane (1), pursuing a stable descent. ing.
- the opening of the umbrella is not a force generated by air resistance, but when the umbrella is opened, an annular hermetic tube (2) provided on the rim that is the largest annular ring and the generation of compressed gas that expands it
- the apparatus (3) is used to deploy and open a parachute designed and produced according to the present invention when necessary, regardless of the descent speed and height during operation.
- a small annular airtight tube (6) and a compressed gas generator (7) can be attached to the tip of the cone separately from the rim, reducing the impact when landing as necessary.
- the compressed gas generator (3) is started, such as automatically pulling with a string or transmitting a radio wave.
- the tube (2) is expanded by the fed gas, and the storage bag is opened or broken, and the parachute is discarded and opened.
- (B) When adopting a drone type representative of a small aircraft, attach a frame that is equipped with a ring and a connection device with a parachute to the drone in advance to protect multiple rotor blades. deep. (Drones seem to be in a variety of colors with no fixed ones yet, but it seems that some of them have been designed with an outer frame from the beginning.) Place in the produced storage bag and bind around the fallout.
- (C) When the fallout is a cargo, attach a connecting device to the cargo and fasten it with a belt.
- This parachute can be provided with an annular tube having the same function as the airtight tube (2) having a plurality of compressed gas generators concentrically between the rim portion and the center. If the gas pressure in the tube (2) is changed, the finding area of the parachute relative to the descent changes, and the descent speed can be changed.
- the umbrella is opened, if the radial load applied to the membrane becomes excessive, the tube (2) shrinks in the circumferential direction or bends to reduce the load.
- FIG. 3 is a conceptual diagram showing the relationship between the lower part of the parachute, the outer frame (8) of the flying object, and the airtight annular tube (6).
- the annular tube (6) is used for absorbing and reducing the impact generated at the time of landing, and is provided with a compressed gas generator as in the case of p (2).
- the annular tube (6) may have a plurality of stages.
- a helicopter When this parachute is used on an aircraft, a helicopter can be fitted with a storage bag or storage device on the axis of the main rotor.
- a storage bag or storage device In the case of airplanes, in the case of high wing type, in the case of low wing type, a containment bag or containment device is provided along the fuselage so that it can be easily discarded or broken by compressed gas. A designed storage device will be provided.
- the use of the tube (2) and the compressed gas generator (3) is effective even in a semi-spherical parapet that has been used in the past, so that accidents that become torches can be reduced or prevented. However, there is a risk that the parachute may be damaged when the falling speed is high.

Abstract
Description
開傘のしたとき、本発明による落下傘は切頭円錘形、つまり、羽子板の羽、バトミントンのシャトルの様なかたちで、本体は薄い膜(1)で出来ており、安定した降下を追求している。開傘は、空気抵抗によって生ずる力でするのではなく、開傘したとき、最大円環となるリム部に設けられた円環状の気密性のチューブ(2)と、それを膨ませる圧縮ガス発生装置(3)を用いて、本発明に依って設計、制作された落下傘を作動時の降下速度および高さに関係なく、必要な時に展開、開傘させるのである。
また円錐の先端部に小型の円環状の気密チューブ(6)と、圧縮ガス発生装置(7)をリム部のものとは別に付けられるようにしておき、必要におうじて着地時の衝撃の軽減に、また水上に着水した時は浮力を得るために備えておく。
従来の落下傘は空中においては,開傘の作動開始から完了までに時間と、降下速度による速度圧を必要としていた。このため、低空では使えなかった。本発明によるものはこれらの条件を必要とせず、圧縮ガスを使って強制的に開傘させるので、降下物を安全に、棄損を少なく着地させることができる。また横方向の衝撃にも、縦方向の衝撃に対してもチューブ(2)、(6)で吸収、対処できる。円環部の形状は、チューブ(2)の圧力を変化させることにより変えることができるので、落下傘の垂直方向の見付け面積を変化させて、降下速度を変えることもできる。さらに、チューブ(2)を周方向で小部屋に区切り、各部屋の圧力を変化させれば、降下方向も操ることもできる。着水時には、チューブの浮力を利用して救命具としても使用できる。
(ロ)小型航空機を代表するドローン形式のものに、採用するときは、複数ある回転翼を保護するため環状の、落下傘との連結用装備が用意してある枠を、あらかじめドローン側に取り付けておく。(ドローンには、まだ定まったものはなく色色な形式が考えられているようだが、はじめから外枠が設計されているものも中にはあるようだ)落下傘は、環状に折りたたみ、おなじく環状に制作された格納袋にいれ、降下物の周囲に結合させる。(ハ)降下物が貨物の時は、貨物に連結装具を取り付け、ベルト等で留める。(ロ)、(ハ)の操作は(イ)と同じである。
この落下傘にはリム部と中心のあいだに、同心円状に複数の圧縮ガス発生器を備えた気密なチューブ(2)と同じ機能をもった円環状のチューブを設けることができる。
チューブ(2)内のガス圧を変化させれば、降下に対する落下傘の見付け面積が変わり、降下速度を変化させることができる。開傘時、膜に加わる半径方向の荷重が過大になればチューブ(2)が円周方向に縮むし、あるいは折れ曲がって荷重を減らすことになる。円錐形の開角が大きく鈍角になったときは、使用時に横滑り、旋回など好ましくない運動が発生することが考えられるが、その時はひだ、またはひれ等を落下傘の下面に設けて、対処することになる。
圧縮ガス発生装置(3)は、別に導管を設けてチューブ(2)から離して設置することもできる。
図3は落下傘の下部・飛行体の外枠(8)および気密性の円環チューブ(6)の関係を示した概念図である。実際に使用するときは、ベルト、ひも等を用いてすべてを強固に緊縛する。円環チューブ(6)は着地時に発生する衝撃を吸収低減させるためのものでp(2)と同じように圧縮ガス発生装置を併設している。円環チューブ(6)は複数段あってもよい。
この落下傘を航空機で利用するときは、ヘリコプターにあっては、主回転翼の軸上に格納袋を、または格納装置を取り付けられるようする。飛行機にあっては高翼型にあっては、主翼の上に,低翼型にあっては胴体にそって格納袋を、または格納装置設け、圧縮ガスによって容易に廃出あるいは、破れるように設計された格納装置を設けることになる。
従来から使用されてきた半円球の落下傘においても、チューブ(2)と圧縮ガス発生装置(3)の利用は有効であり、トーチになる事故を減らす、あるいは防ぐことができよう。ただし、落下速度の速いときは落下傘が破損するする恐れがある。
また、新しく登場してきたドローン形式の航空機の発展には、大きく、寄与するものと思われる。
