Description
第1の一次反応室130および第2の一次反応室140を、二次反応室に連結された並列の配置で備える実施形態を、ここでより詳細に説明する。
第2の一次反応室140を備えていない、つまり、燃料リッチ単元推進薬のための一次反応室130だけを有する本発明の代替の実施形態を、ここでより詳細に説明する。
本発明のデュアルモード推進システムの実施形態の簡略化された水力学的な概略図が、図1に示されている。サービス弁22および32が、運転前に推進薬を推進システムへと充填するために使用されている。例えばLMP−103Sといった、燃料リッチ単元推進薬が推進薬容器21に収容されており、例えば非常に濃縮された過酸化水素H2O2、または代替で、酸化剤リッチHANもしくはADNに基づいた単元推進薬混合物といった、酸化剤リッチ単元推進薬が推進薬容器31に収容される。例えばヘリウムといった、高い圧力(つまり、数十メガパスカル(数百バール))に加圧しているガスが、推進システムの運転の前に、サービス弁11を介して加圧剤容器10へと充填される。推進システムは、遮断弁24および34の下流で推進薬配管における締め切りガスを放出することによって作動され、その後、最初の点火の前に推進薬のスラスタへの呼び入れを実施する。いずれかのスラスタを点火するとき、容器10からの加圧剤ガスが、圧力調節器12によって、ロケットエンジン運転推進薬供給圧力(つまり、数メガパスカル(数十バール))に下げるように調節される。加圧剤は、推進薬遮断弁13を通り、さらに逆止弁20および30を通り、推進薬容器21および31へと流れる。運転モード、つまり、単元推進薬モードまたは二元推進薬モードに応じて、推進薬容器21もしくは31のいずれか、または、両方からの推進薬が、点火するとき、推進薬フィルタ23および33をそれぞれ通り、主題のエンジンへと流れる。
