翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク T-stage ： ウィキペディア英語版 T-stage T-stages, sometimes called booster stages, are mounted on the low pressure (LP) shaft of some turbofan engines directly behind the fan.〔 http://www.flightglobal.com/pdfarchive/view/1969/1969%20-%201658.html?search=%22thrust%20growth%22〕 T-stages are used to increase overall pressure ratio and, for a given core size, the core mass flow. This is demonstrated by the following relationship: :$w\_2\; =\; (w\_2\; \backslash sqrt/P\_3)\; )$ * (P_3/P_2) * (P_2/P_1) *( P_1/ \sqrt)/ (\sqrt * \sqrt ), :where: :hp compressor entry mass flow = $w\_2\; \backslash ,$ :core size = $(w\_2\; \backslash sqrt/P\_3)\; \backslash ,$ :hp compressor total head pressure ratio = $P\_3/P\_2\; \backslash ,$ :lp compressor total head pressure ratio = $P\_2/P\_1\; \backslash ,$ :lp compressor entry total pressure = $P\_1\; \backslash ,$ :lp compressor entry total temperature = $T\_1\; \backslash ,$ :hp compressor total head temperature ratio = $T\_3/T\_2\; \backslash ,$ :lp compressor total head temperature ratio = $T\_2/T\_1\; \backslash ,$ which varies more slowly than $P\_2/P\_1\; \backslash ,$ So as $P\_2/P\_1\; \backslash ,$ increases with the addition of T-stages, $w\_2\; \backslash ,$ also increases. T-stages are a popular method for uprating the thrust of an engine (see, for example the Pratt & Whitney Canada PW500). The alternative is to place a zero-stage, mounted on the HP shaft, at the front of the HP compressor. This approach requires a significant change in the HP turbine, whereas a T-stage can, if necessary, be accommodated by simply adding another stage to the rear of the LP turbine. Although T-stages usually only supercharge the core stream, some engines do feature a deliberately oversized intermediate pressure (IP) compressor, which compresses both the core flow and a proportion of the bypass flow. This enhances the stability of the T-stages during throttling. Where necessary, the alternative is to employ blow-off valves. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「T-stage」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
