Ultra-high-speed flight model deceleration recovery device and method

The invention relates to an ultra-high-speed flight model deceleration recovery device and method. The device comprises a sponge buffer area and a paraffin recovery area, wherein the sponge buffer area comprises multiple flame-retardant sponge layers, the density of the single flame-retardant sponge layers is uniform, the flame-retardant sponge layers are tightly attached layer by layer in the model launching direction, the density and the layer sectional area of each flame-retardant sponge layer are increased layer by layer, and the paraffin recovery area is arranged on the side, away from a model, of a flame-retardant sponge buffer area and used for decelerating and recovering the model. According to the ultra-high-speed flight model deceleration recovery device and method, soft recovery of the model with the mass larger than 1 kg and the launching speed larger than 1.5 km/s can be achieved. 本发明涉及一种超高速飞行模型减速回收装置及方法，该装置包括海绵缓冲区和石蜡回收区，海绵缓冲区包括多层阻燃海绵层，单层阻燃海绵层的密度均匀，各层阻燃海绵层沿模型发射的方向逐层紧贴设置，且各阻燃海绵层的密度和层截面积均逐层增加；石蜡回收区
