The TQ-15 (Chinese: 天鹊-15; pinyin: Tiānquè-15, lit. Sky Lark 15) is a gas-generator cycle rocket engine burning liquid methane and liquid oxygen under development by Landspace. The most recent version of the TQ engine family, the TQ-15A, is intended to power the second stage of LandSpace's upgraded Zhuque-2 rocket. [1]

天鹊-15A （TQ-15A）是由 蓝箭航天 自主研制的泵前摆 燃气发生器循环 真空型液氧甲烷火箭发动机，与 天鹊-12A 通用涡轮泵、阀门、燃气发生器等关键组合件。 [1] TQ-15A发动机真空推力提高9%，真空比冲提高130 m/s，推力调节范围拓宽至55%~110%且具备三次起动能力，可大幅提升火箭发射任务的适应性。 [2] 与现役的 朱雀二号 火箭二级发动机相比，其优势表现在： 涡轮排气引入推力室喷管延伸段，提高了发动机比冲性能，且减少了发动机侧向力。 [1] 推力室进一步增 …

tq-15a是“天鹊”家族真空型液氧甲烷发动机，2022年9月25日在湖州智能制造基地完成首台装配，于2022年10月8日交付试车台进行试车考核。tq-15a为目前国内推力最大的真空型液氧甲烷发动机，真空推力达836kn，是朱雀二号火箭第二批次的二级主发动机。

2022年10月19日 · TQ-15A 发动机真空推力提高 9%，真空比冲提高 130m / s，推力调节范围拓宽至 55%~110% 且具备三次起动能力，可大幅提升火箭发射任务的适应性。 本台 TQ-15A 发动机为带伺服机构不带大喷管状态，本次试车重点考核发动机系统、总装和各组合件改进方案的可行性，验证起动关机时序的正确性，获得发动机的实测性能数据及工作特性。 发动机按预定程序起动和关机、工作平稳，达到了预期设计目标。
