On 24 January, the Laboratory of Spray Combustion and Propulsion of the School of Aerospace Engineering at Tsinghua University, successfully conducted a test flight for a new engine that experts said could power China's future hypersonic aircraft and near-space plane, CCTV reported.
A two-stage rocket booster was used to assist the test flight, CCTV said, noting that after the separation of the 1st stage, the 2nd stage sent the engine to the predetermined height and velocity, and that was when the air inlet of the engine began to breathe in air very efficiently, and the fuel supply system began to spray vaporized jet fuel into the combustion chamber.
