The TQ-11 (Chinese: 天鹊-11; pinyin: Tiānquè-11, lit. Sky Lark 11) is a gas-generator cycle methalox rocket engine under development by Landspace. It will be used as the second stage vernier engine for Landspace's ZQ-2 rocket.[2][3][4] The engine has been designed to produce 80 kilonewtons (18,000 lbf) of thrust in the vacuum.[1] Landspace completed the first engine hot firing test for TQ-11 on November 3, 2019, and the engine passed a 1500 second test in 2020.[2][4]
