 note = {液酸/ガス水素,液酸/ガスメタンおよび液酸/RJ-1Jを用いた水冷却高圧燃焼試験を最大燃焼圧10MPa,最大熱流束100MW/m2の範囲で実施した。ここでは各推進剤における燃焼ガス側熱伝達特性について比較検討した。さらに液酸/RJ-1J系において壁面上に生じたカーボン層の熱抵抗について論じた。実験により同軸噴流型エレメントを有する噴射器を使用した液酸/ガス水素,及び液酸/ガスメタンの場合の熱流束分布は,噴射器近傍からスロートに至る範囲では計算値とほぼ一致した。また,噴流衝突型エレメントを有する噴射器を使用した液酸/RJ-1Jの場合の熱流束分布は計算値よりかなり低い値を示した。この原因として炭化水素系燃料に特有な,燃焼ガス中のカーボンが燃焼室壁に堆積したことによる熱抵抗の影響と推定された。この熱抵抗の値は,同一の燃焼ガス質量流束の下では従来のデータの数％であることがわかった。, Combustion tests were conducted using liquid oxygen(LOX)/gaseous hydrogen, LOX/gaseous methane and LOX/RJ-1J as propellants. Two water-cooled calorimetric combustors and two types of injectors, i.e., a coaxial and an impinging injector, were used. The maximum chamber pressure was 10MPa and the heat flux reached 100MW/m2 in the maximum. Heat flux values measured at the throat section were lower than those predicted by the simplified Bartz's equation. A modified Bartz's equation, which uses 0.023 as a coefficient (instead of 0.026 as in the original) and which takes into account the injector and effect as well as the film cooling effect, more accurately predicted the measured heat flux distribution of the coaxial type injector. With regard to LOX/RJ-1J propellants, an empirical correlation for the thermal resistance of the carbon layer deposited on the chamber wall was obtained. It was observed that the values of thermal resistance measured were a small percentage of the values found in previously published data., 資料番号: NALTR1062000, レポート番号: NAL TR-1062T},
