The turnover of the heat-preserving flip 108 is used for sealing the metal sealing cover 105 of the phase-change material, so that a heat-preserving effect is achieved, heat loss of the target aircraft during high-altitude flight is reduced, and meanwhile, the target simulation is provided by reaching the infrared characteristic exposure space region to show the infrared characteristic. When the target aircraft does not need infrared characteristics, the heat preservation flip 108 can be rotated to carry out closed heat preservation on the metal sealing cover 105, so that the energy loss rate is reduced.

When the heat-preserving flip 108 is opened, the metal cover 105 of the heat-preserving material is subjected to heat conduction and heat radiation heat transfer through the internal phase-change material, so that the temperature of the metal cover 105 can be maintained at a temperature which is 0-30 degrees different from the temperature of the internal phase-change material, and the infrared heat radiation characteristic is displayed, and the heat-preserving flip can be used for identifying and tracking the infrared characteristic emitted by the target aircraft infrared characteristic generator device, so that the infrared guided weapon device can be used for testing and training various tracking striking performances.
When the nondestructive testing and training are finished, the heat-preserving flip 108 can be closed through signal control to reduce the heat loss of the equipment, and the energy on the target aircraft can be used for heat supplement so as to realize multi-stage and multi-layer utilization of the infrared characteristic generating equipment, so that the testing and training cost is reduced.
