Abstract
Description
この発明は、航空機等に使用するパルスジェット・エンジンの形状と運用に関する。The present invention relates to the shape and operation of a pulse jet engine used for an aircraft or the like.
従来の航空機等に使用されているパルスジェット・エンジンの形状と運用方法は、パルスジェット・エンジンの特性上、使用の際にある程度の加速が必要で、その為にロケットエンジン等を使っていた。The shape and operation method of the pulse jet engine used in the conventional aircraft and the like requires a certain degree of acceleration during use due to the characteristics of the pulse jet engine, and therefore a rocket engine or the like has been used.
しかしながら以上の技術によれば、パルスジェット・エンジン以外にも、ロケットエンジン、その他のエンジン等を積まなければ離陸が不可能であり、重量の増加や、騒音の増加を招く。
そこでこの発明は、使用の際にロケットエンジン等の加速を必要としないパルスジェット・エンジンを提供する事を課題とする。However, according to the above technology, it is impossible to take off unless a rocket engine, other engines, etc. are loaded in addition to the pulse jet engine, resulting in an increase in weight and noise.
Accordingly, an object of the present invention is to provide a pulse jet engine that does not require acceleration of a rocket engine or the like when used.
以上の課題を解決する為に、第一発明は、空気流入の為の開閉口を漏斗と円錐の組み合わせ型にし、加速の必要が無いように、その前方に高速回転するファンを使用する事を特徴とした、パルスジェット・エンジンである。In order to solve the above problems, the first invention is to use a funnel-cone combination opening / closing port for air inflow, and to use a fan that rotates at a high speed in front of it so that acceleration is not necessary. It is a featured pulse jet engine.
第一発明によれば、ロケットエンジン等による加速による空気流入ではなく、空気流入の開閉口の形状を漏斗型と円錐型の組み合わせ型に改良し、それにより電気モーター等の高速回転で発生する気流を、従来のパルスジェット・エンジンよりも効率よく集束し、流入させることで、結果的にロケットエンジン等で加速した事と同じ効果が得られる。According to the first invention, the air flow generated by high-speed rotation of an electric motor or the like is improved by improving the shape of the opening / closing port of the air inflow to a combination type of a funnel type and a conical type instead of air inflow due to acceleration by a rocket engine or the like. As a result, the same effect as acceleration by a rocket engine or the like can be obtained.
この発明の実施形態を図1に示す。パルスジェット・エンジンの空気流入の為に使われる開閉口を漏斗と円錐の組み合わせ型としている。エンジン本体の材質等は従来の物であっても十分であると思われる。An embodiment of the present invention is shown in FIG. The opening used for the air inflow of the pulse jet engine is a combination of a funnel and a cone. It seems that conventional materials are sufficient for the engine body.
「実施形態の効果」
この実施形態によれば、開閉口を漏斗と円錐の組み合わせ型にする事により、空気の流入が改善され前方に高速回転する電気モーター・ファン等を使う事により、ロケットエンジン等の加速を必要としない。"Effect of the embodiment"
According to this embodiment, the opening and closing port is a combination type of a funnel and a cone, so that the inflow of air is improved and an electric motor, a fan, etc. that rotates at a high speed forward is used. do not do.
「他の実施形態」
円錐であろうと角錐であろうと、漏斗との組み合わせが守られていれば、理論上は使用できる。航空力学や流体力学の観点から言えば、漏斗との組み合わせは円錐と行なうのが良い。
高速で回転するファン等の回転動力は、電気モーターでも内燃機関でも問題はない。"Other embodiments"
Whether it is a cone or a pyramid, it can be used theoretically if the combination with the funnel is protected. In terms of aerodynamics and hydrodynamics, the combination with a funnel should be done with a cone.
There is no problem with the rotational power of a fan or the like that rotates at a high speed in either an electric motor or an internal combustion engine.
(a)回転動力(電気モーター、内燃機関等)
(b)ファン、プロペラ
(c)円錐型開閉弁
(d)漏斗型空気取り入れ口
(e)燃料噴霧装置
(f)スパークプラグ、点火装置
(g)開閉弁
各図の▲1▼▲2▼は、▲1▼が通常状態及び燃焼直後の形態で、▲2▼が空気流入時の形態の図である。実際に使用する際は、円錐型開閉弁と漏斗型空気取り入れ口には、それぞれを連結し、開閉弁の動きを空気の流れの強弱によって稼動させるばねや、センサー付き油圧式のサスペンション等を使用しなければならないが、この図1では省略する。空気の流入が改善される根拠は、漏斗型にする事で空気流が中心に集束しやすくなる。円錐型の開閉弁は、円錐に対して、空気が流れると空気の流れが円錐の先端部から、回転して流れる従来のターボ・ジェットエンジンなどに使われている技術根拠とほぼ同じである。
これらを組み合わせて、パルスジェット・エンジンに使用する事は、今までのところ見られない。(A) Rotational power (electric motor, internal combustion engine, etc.)
(B) Fan, propeller (c) Conical open / close valve (d) Funnel air intake (e) Fuel spray device (f) Spark plug, ignition device (g) Open / close valve , (1) is the normal state and the form immediately after combustion, and (2) is the form at the time of air inflow. When actually used, the conical on-off valve and funnel-type air intake are connected to each other, and springs that operate the on-off valve according to the strength of the air flow, hydraulic suspension with sensors, etc. are used. This is omitted in FIG. The basis for improving the inflow of air is that the air flow is easily focused on the center by using a funnel type. A conical open / close valve is substantially the same as the technical basis used in a conventional turbojet engine or the like in which a flow of air flows from the tip of a cone when the air flows relative to the cone.
The combination of these has not been used so far for pulse jet engines.
