200537008 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種具有一用於改良空氣動力及熱效能之 具扇片之後緣水滴型陣列之渴輪機引擎組件。 【先前技術】 許多渦輪機葉片具有内部冷卻通道。通常，最後的冷卻 通道中之流體於葉片之外部噴射。此一冷卻液喷射系統展 不於Anselrai等人之美國專利第5,5〇3,529號中。另一此類 葉片展示於Reddy之美國專利第6，164,913號中。
AnSelrai等人之專利展示了 一具有角形噴射槽之渦輪機 葉片。該等喷射槽形成於一翼面側壁中。與該等槽鄰近的 係隨後用於引導流體之複數個錐形肋部。為了使冷卻液過 道中之流進入一槽中，該液動必須轉動9〇度以上。因此， Anselrai等人之葉片具有差的熱效能。
Reddy之葉片與Anselrai等人之葉片在設計方面類似。在 φ Reddy之葉片中’喷射槽排空冷卻液流體，該冷卻液流體 流出至一排列於直接鄰近後緣之管柱中之水槽中。水槽之 管柱安置於葉片之壓力側壁中。每一水槽都具有在深度上 減少以用於摻合水槽下游至後緣之側壁。另外，每一水槽 之側壁徑向分叉以分佈自槽中所喷射之冷卻液。該葉片亦 遭受差的熱效能。 在滿輪機之應用中’渴輪機葉片之翼面部分中流過薄脖^ 孔與後緣出口之冷卻液空氣導致效率損耗，此係歸因於冷 卻液注入與氣路混合並加速了冷卻液變為自由流之速&。 98822.doc 200537008 自由流氣路與冷卻液注入之間之角度愈大，效率損耗就愈 大。雖然水滴型設計在此項技術中已為吾人所知，但是此 等設計通常係軸向設計而不考慮氣路流線角。 【發明内容】 本發明之一目的係提供一種渦輪機引擎組件，該組件藉 由使冷卻液注入槽部件與非軸向翼面表面流線相對準而具 有降低之空氣混合損耗，其可改良總渦輪機混合效率並使 額外混合損耗最小化。 本發明之另一目的係提供一種渦輪機引擎組件，該組件 因該注入冷卻液流與該主流氣體之流線方向間之相對散射 角的減小而具有改良之熱效能。 本發明之又一目的係提供一種改良之後緣槽薄膜效力及 改良之内部效能。 可藉由本發明獲得上述目的。 根據本發明，其提供一用於燃氣渦輪機引擎中之組件。 該組件大致地包括··-具有後緣之翼面部分；及用於藉由 減小注入冷卻液流與經過翼面部分之流體之流線方向:門 的-相對散射角而使該組件之熱效能最大化之構件。該组 件可為包含但不限於葉片及輪葉（vane)之各種渴輪機料 組件。 具扇片之後緣水滴型陣列之其他細節以及與其伴隨之盆 目的及優勢陳述於下列詳細描述與隨附圖式巾，在該 圖式中，相同的參考數字描繪相同的元件。 ^ 【實施方式】 98822.doc 200537008 現簽看圖1，其展示一待用於燃氣渦輪機引擎中之組件 、. 。組件10可為渦輪機葉片或輪葉。組件1〇包括一具有前 -· 緣14及非線性（弓狀較佳）型後緣16之翼面部分12。組件1〇 之内部係冷卻通道18、20、22及24。同時，組件10之内部 係後緣冷卻通道26，該通道具有一用於接收冷卻流體之入 口 28。 複數個冷卻流體注入槽30位於組件丨〇之後緣區域中。注 φ 入槽30係由間隔分離式水滴型總成32之非線性（弓狀較佳） 陣列形成。每一水滴型總成32較佳地具有一弓狀前緣“、 自弓狀前緣34向外延伸之平坦部分36與38以及自平坦部分 36與3 8延伸至後緣44之錐角形部分4〇與42。平坦部分36與 38之範圍取決於通過槽3〇之流。必要時，可省略去平坦部 分36與38。每一水滴型總成32具有一中心縱向軸線补。注 ^槽30被設計以產生一扇形冷卻液流，該冷卻液流可模擬 氣路自由流（參見圖1與3)。 • 冷卻通道26具有複數個出口 50,冷卻流體通過該等出口 離開通道26。出口 50亦排列成非線性（弓狀較佳）陣列。每 一個別出口 50係由一對安置於弓狀壁53與55之一者中之間 隔分離式肋部52與54所形成。每—冷卻流體出口5〇具有一 中〜轴線56 ’該中心軸線較佳地與一水滴型總成之縱向 軸線46對準。 位於出Π5〇與水滴型總成中間的係複數個基架6〇,該等 基架形成複數個流通道62。如可自圖m2所見，基架6〇之 岔度在翼展方向中變化。组態基架60,使得於-出口 5〇排 98822.doc 200537008 放之机直接衝擊至_基架6〇上。由基架6〇所形成之流通道 人/主入乜30車父佳軸向地對準。另外，如可在圖2中所 - 1 ’複數個基架6G可沿著—軸線對準，該軸線與水滴型總 成32之中心縱向軸線仏重合。 、 藉由提供上述結構，可能藉由使冷卻液注入槽3〇與非軸 向翼面表面流線對準而降低空氣混合損耗。以此方式改良 了總滿輪機混合效率，並使伴隨軸向對準之水滴出現之額 _ 外混合損耗最小化。 另夕卜上述結構藉由減小注入冷卻液流與主流流體之流 線方向之間的相對散射角而使熱效能最大化。冷卻液與主 L體机之間的相對散射角之減小會使用於自水滴散射體 中刀離机之勢月匕最小化。自後緣水滴型部件中分離流可導 夂後緣區域之過早氧化，從而導致涡輪機效率、效能及翼 面壽命加速降低。 本^月之nx计亦使由離開非軸向後緣水滴型部件非分離 •、流產生之後緣槽薄膜效力最優化，其增加後緣絕熱薄臈效 力並減少吸入側邊緣金屬溫度，從而導致熱效能改良。 土月之叹。十藉由使後緣水滴型部件與上流冷卻液流場 方向對準而使内部流分離之勢能及離開後緣水滴型部件之 額外壓力損耗最小化’從而導致特定幾何形狀與流面積之 後緣迴路之總流量減少。流量減少可能會對後緣設計之細 Α熱效能產生不利影響’將其對於固定操㈣力比之冷卻勢 能自h給減小至g轉儲。 本發明之非軸向水滴型部件藉由使鄰近水滴型部件間所 98822.doc 200537008 需喉管量器長度最小化而改良了陶究芯之可生產性。由於 重要的是應確定有效計量長度以精確控制後緣槽流，因而 需要基於槽液壓直徑之最小槽長度。假如給^局部後緣之 軸向弓形及曲率’則有利於定向如上文所示之水滴型部 件，以使確定完全展開之流所必需之所f量器長度最小 化。如此，可減小總水滴型長度，其顯著改良了後緣水滴 ^•邰件之轉動t貝里特徵’並改良了後緣芯之總剛性及可生 產性。
藉由使如圖W2中所示之本發明之水滴型總成具扇形以 匹配圖3中所示之自由流，效率損耗可顯著減小。 很顯然，已根據本發明提供了一具扇片之後緣水滴型陣 列，其完全滿足上文所陳述之目的、手段及優勢。儘管本 發明已於其特定實施例之内容中得以描述，但是已閱讀上 述4田述之熟習此項技術者將明白其他替代、修改及改變。 因此’本發明意欲包含屬於附加申請專利範圍之寬廣範疇 内之此等替代、修改及改變。 【圖式簡單說明】 圖1說明根據本發明之渦輪機引擎組件； 圖2係圖1之渦輪機引擎組件之後緣部分之放大圖，其展 示本發明之具扇片之後緣水滴型陣列；及 圖3說明氣路自由流線。 【主要元件符號說明】 1〇 組件 12 翼面部分 98822.doc -10- 200537008
