An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

Welkin (Chinese: 苍穹; pinyin: Cāngqióng) is a gas-generator cycle rocket engine burning RP-1 and liquid oxygen under development by Galactic Energy. The engine features a pintle type injector, a double suction coaxial split turbine pump, and a gas generator using vortex principle. The engine was built with reusability in mind and can be deep throttled to 20% and re-used up to 50 times.

  • Welkin (Chinese: 苍穹; pinyin: Cāngqióng) is a gas-generator cycle rocket engine burning RP-1 and liquid oxygen under development by Galactic Energy. The engine features a pintle type injector, a double suction coaxial split turbine pump, and a gas generator using vortex principle. The engine was built with reusability in mind and can be deep throttled to 20% and re-used up to 50 times. Galactic Energy's Pallas-1 reusable launcher will be powered by Welkin engines. Seven Welkin engines producing 280 tonnes of thrust will be powering the first stage, while the second stage will be powered by a single vacuum-optimized engine. The engine successfully completed its first full-power test in March 2022. (en)
  • 苍穹（英語：Welkin）是星河动力公司研制中的液氧煤油火箭发动机，采用燃气发生器循环。该发动机的特点是采用了针式喷射器，双吸式同轴涡轮泵，以及采用了涡流原理的燃气发生器。发动机为重复回收使用而设计，可将推力深度节流至20%，并可重复使用50次。 (zh)
