| description | The invention discloses a solid rocket engine propellant debonding detection device and method, the detection device comprises a sleeve optical cable, a tightly-packaged optical cable, a demodulator and a data processing unit, the sleeve optical cable and the tightly-packaged optical cable are arranged in parallel between an engine shell and a bonding interface of a propellant; the sleeve optical cable is used for detecting the optical fiber Brillouin frequency shift change of a bonding interface caused by the temperature change, the tightly-packaged optical cable is used for detecting the optical fiber Brillouin frequency shift change of the bonding interface caused by the combined action of the temperature change and external force, and the sleeve optical cable and the tightly-packaged optical cable jointly form debonding detection optical cables. The debonding detection optical cables are uniformly arranged in the bonding interface along the inner circumference of the engine shell, the plurality of debondi |
