新华社西安７月２９日电（记者陈钢）７月２９日，我国新一代大推力液氧煤油火箭发动机在西安进行的“极限工况热试车”获得成功，进一步验证了其稳定性和可靠性。

    The xinhua news agency on July 29, xian（Reporter ChenGang）July 29,，The country's new generation big thrust lox kerosene rocket engine in xian“Limit condition hot commissioning”success，Further to verify its stability and reliability。

    此次进行极限工况热试车的液体火箭发动机，单台推力为１２０吨，由位于西安南郊的中国航天科技集团第六研究院研制。航天六院是我国唯一集运载火箭主动力系统、轨姿控动力系统及空间飞行器推进系统于一身的设计制造单位。

    The working conditions of the test to extreme hot liquid rocket engine，Single machine for 120 tons of thrust，Located in the south of xian by China aerospace science and technology corporation developed 6 research institute。Space six court is the only rocket characteristic collection system、Rail power system and the attitude control space vehicle propulsion system in one of the design and manufacture of the unit。

    据航天六院科研人员介绍，现阶段我国使用的液体火箭发动机单台推力是７０吨左右。未来我国要建设太空实验站，需要更大推力的火箭发动机。

    According to the scientific research personnel introduces six space，At present in China the use of liquid rocket engine thrust is single machine around 70 tons。Future in China to build space lab，Need more big thrust of rocket engine。

    历经十多年研制的１２０吨级液氧煤油发动机，是我国首型拥有自主知识产权的高压补燃循环发动机，具有高性能、高可靠、无毒无污染等特点。它的研制成功，意味着我国成为继俄罗斯之后第二个掌握液氧煤油高压补燃循环火箭发动机核心技术的国家。该型发动机前不久经过了项目验收。

    After 10 years of development of 120 t liquid oxygen kerosene engine，Is our country the first type with independent intellectual property rights of the high pressure complementary combustion engine cycle，With high performance、High reliable、Non-toxic non-pollution etc. Characteristics。The successful development of it，Means our country after Russia became the second master liquid oxygen kerosene fuel cycle rocket engine for high pressure core technology of the country。This type of engine recently after the project acceptance。

    据介绍，７月２９日进行极限工况热试车的液体火箭发动机，已经历过两次长达６００秒的点火试验，经过了长途颠簸运输后，又经过了３年的储存。此次点火试验，就是要在高转速、高温的极限状态下，检测发动机是否可以保持稳定和可靠。这台发动机在极限考验中表现完美，预示着中国航天动力的新旧更迭将加快。

    According to introducing，July 29, to extreme conditions of hot commissioning liquid rocket engine，Has experienced two times for 600 seconds of ignition experiments，After a long distance transport turbulence，And after three years of storage。The ignition experiments，Is to high speed、The limit of the high temperature condition，Testing whether can keep engine stable and reliable。This engine test in limit perfectly，That China's space power of the old and new alternate will speed up。
