Abstract

本發明係有關一種三軸直升機，主要包含機殼及機身，位於機身組設有三組旋翼組以及驅動源，且於機身尾端架設有二渦輪風扇，並於二渦輪風扇之間設水平升降舵，且水平升降舵透過連桿組組接於驅動源，藉此，使三軸直升機運作時，能利用二渦輪風扇運轉所產生的向後氣流來協助將三軸直升機往前推進，以增進三軸直升機飛行的速度，並於三軸直升機欲上升或下降時，藉驅動源控制連桿組依上升或下降需求來調整水平升降舵的偏擺方向，使渦輪風扇所產生的氣流隨水平升降舵的方向吹送，進而增加三軸直升機升降力。

Description

三軸直升機
本發明有關一種直升機，尤指能透過渦輪風扇加速氣流推進的三軸直升機者。
按，直升機為透過旋翼旋轉飛行的飛機，且無需跑道即能垂直升降起落，因此，目前已普遍應用於觀光旅遊、災害救援、海上救援、緝私緝毒、消防、商務運輸、醫療救助、農業以及資源探勘…等領域。
而一般直升機飛行時，能藉由直升機的旋翼水平旋轉來達成使直升機垂直升起或落下的目的，但欲控制直升機前進時，則需透過操控機身或旋翼前傾的角度使氣流往後吹送進而將直升機往前推進，然而，直升機機身的前傾角度不易控制，若前傾角度過大，則容易受風壓影響而形成直升機的前進阻力，甚至因風壓過大造成直升機無法平衡而墜毀。
為改善上述缺失，遂申請人於2014年申請有中華民國第103134614號專利，係揭露一種「多軸直升機之推進加速裝置」，主要是在機體下方設置包含驅動單元及水平推進器的推進加速裝置，以藉油門控制組操控直升機的速度，並將所感測的訊息回饋給驅動單元，且由驅動單元驅動連動水平推進改變夾角，進而使直升機能穩定的高速行駛。
有鑑於習知直升機透過操控機身或旋翼前傾角度的方式來控制直升機往前推進，容易因風壓影響而破壞平衡，故仍有待改進的空間。
是以，本發明的目的是透過於直升機設置渦輪風扇，以藉渦輪風扇運轉時所產生的氣流來推進直升機前進。
本發明的另一目的是透過於二渦輪風扇之間設水平升降舵，使渦輪風扇所產生的氣流能朝水平升降舵的偏擺方向吹送，進而增加直升機升降力。
為達前述目的，本發明提供一種三軸直升機，該三軸直升機包含機殼及機身，位於機身組設有三組旋翼組以及一驅動源，其特徵在於：該機身尾端架設有二渦輪風扇，且於二渦輪風扇之間設有一水平升降舵，該水平升降舵透過一連桿組組接於驅動源，且水平升降舵兩端位於渦輪風扇之扇葉運轉部分範圍內。
基於上述，使三軸直升機運作時，能利用二渦輪風扇運轉所產生的向後氣流來協助將三軸直升機往前推進，並於三軸直升機欲上升或下降時，藉驅動源控制連桿組依上升或下降需求來調整水平升降舵的偏擺方向，使渦輪風扇所產生的氣流隨水平升降舵的方向吹送，進而增加三軸直升機升降力。

第5圖係本發明三軸直升機下降之示意圖。
為使達成本發明目的之技術內容能有更完整的揭露，茲於以下內容詳述之，並請一併參閱所揭之圖式及圖號：首先，請參閱第1圖並配合第2圖所示，該三軸直升機1包含機身11及機殼12，位於機身11組設有三組旋翼組13以及一驅動源14，且於機身11尾端架設有二渦輪風扇15，並於二渦輪風扇15之間設一水平升降舵16，且水平升降舵16透過一連桿組17組接於驅動源14；於本發明之實施例中，驅動源14為伺服馬達。
其次，請繼續參閱第3圖所示，當三軸直升機1的三組旋翼組13旋轉運作且欲朝前方飛行時，能透過設於機身11尾端的二渦輪風扇15將空氣朝後方吹送，使三軸直升機1能藉往後吹送的空氣向前推進，而無需調整機身11或旋翼組13的前傾角度。
且當三軸直升機1欲上升時，請配合參閱第4圖，驅動源14會驅動連桿組17將水平升降舵16與連桿組17的連接處往上頂，使水平升降舵16形成尾部161朝下的角度，由於水平升降舵16兩端位於渦輪風扇15其扇葉運轉的範圍內，因此，二渦輪風扇15運轉時所產生的推進氣流會沿 著水平升降舵16的方向朝下方吹送，藉此，透過調整推進氣流與空氣的方向來加速三軸直升機1上升。
而三軸直升機1欲下降時，請配合參閱第5圖，驅動源14會驅動連桿組17將水平升降舵16與連桿組17的連接處往下拉，使水平升降舵16形成尾部161朝上的角度，此時，二渦輪風扇15運轉時所產生的推進氣流會沿著水平升降舵16的方向朝上方吹送，藉此，透過調整推進氣流與空氣的方向來加速三軸直升機1下降。
是以，使用本發明的三軸直升機顯然能達成如下之功效：
1.本發明的三軸直升機能透過設於機身尾端的二渦輪風扇運轉時所產生的氣流將三軸直升機往前推進，故無需調整機身或旋翼組的前傾角度，增進三軸直升機飛行的速度，避免三軸直升機因急速前進而不平衡甚至墜毀。
2.本發明的三軸直升機於二渦輪風扇之間設有水平升降舵，且水平升降舵的兩端位於渦輪風扇氣流輸出的範圍內，使渦輪風扇所產生的氣流能沿著水平升降舵朝下或朝上的方向吹送，進而增加三軸直升機升降力。
惟以上所述者，僅為本發明之較佳實施例，並非用以限定本發明之實施範圍，凡未脫離本發明技藝精神所為之變化與修飾，皆為本發明專利範圍所涵蓋。
綜上所述，本發明確實已突破傳統並具有改良及創新之創作內容且能具體實施，理應符合發明專利之法定要件，爰依法提出專利申請，懇請 鈞局審查委員授予合法專利權，以勵創作，至感德便。
