Abstract:Based on the special sensor and multi-point measure, a new method is proposed using temperature extrapolation method to get the in-wall temperature of the closed-bomb.First,the temperature change on lowly dynamic characteristics position is measured£¬and then in-wall temperature is extrapolated according the rule of heatª²transfer£®So the requirements of highly dynamic characteristics in measuring the inª²wall temperature of the closedª²bomb can be easily satisfied by the proposed method,the influence of the sensor coat-thickness on transient temperature measurement can be eliminated,and the correctness of the measurement can also be verified.The experimental results show that the measurement of changing regulation of the in-wall temperature of the closedª²bomb can be realized and the error in the verifying points is less than 1 ¡æ£®
