The invention relates to a rapid prediction method for the stable stage of stacked biradical propellant powder. The rapid prediction method comprises the following steps: preparing a modeling sample of II-centralite available content near-infrared quantitative model of the biradical propellant powder by virtue of a thermal accelerated ageing method, and establishing the II-centralite available content near-infrared quantitative model by virtue of a near-infrared spectrum and chemometrics; establishing a stable stage prediction equation by virtue of a reliable temperature coefficient r0; and tracking the II-centralite available content in the thermal accelerated ageing process of the stacked biradical propellant powder by virtue of a near-infrared method, so as to obtain consumed critical time that the available content reaches critical criterion, and extrapolating the working condition and the stable stage of the stacked propellant powder under the storage environment temperature by virtue of the stable stage prediction equation. According to the rapid prediction method, the stable stage can be acquired only through the lossless tracking of the available contents of a sample at a temperature and different ageing time periods by virtue of the near-infrared method, the sample amount is reduced by 96%, and the method is safe and low in cost.
