The utility model relates to a technical field is retrieved to the space flight testpieces, specifically discloses a hierarchical loaded low brake recovery system that overshoots. The braking air supply includes high pressure braking air supply and low pressure braking air supply among this brake recovery system, wherein, high pressure braking air supply be connected with high -pressure pipeline, provide high brake pressure for high -pressure pipeline, low pressure braking air supply be connected with the low pressure pipeline, hang down brake pressure for the low pressure pipeline provides, the back end of back end and high -pressure pipeline of low pressure pipeline communicate with each other the back and be connected with brake equipment the anterior segment of low pressure pipeline be equipped with the low pressure solenoid valve the anterior segment of high -pressure pipeline be equipped with high pressure solenoid. When this set device was retrieved at the chorista to velocity of movement 12ms, the ratio that will cross impulsive force and the steady section power of retrieving be 2 times from 3.5 times of reduction, and that has guaranteed the weak intensity structure separate body cushions the recovery safely.
