In this work we put forward a new method for calculating the detonation velocity of composite explosive based on the concept of the ideal composite explosive model, and constructed the characteristic detonation velocity equation of air and aluminum with explosive composition. Using this method, we performed calculation of the detonation velocity for 26 mixed CHNO explosives, 13 pure CHNO explosives, and 25 aluminized explosives, all of whose maximum theoretical charge density is more than 85%. The results showed that the calculated detonation velocities were in good agreement with the experimental values. The average relative error was 0.01% and the square of the correlation coefficient is 0.9615. Compared with the commonly adopted methods such as Kamlet and Urizar, the new method was more accurate. The new method not only provides a new way to calculate the detonation velocity of CHNO explosives and CHNOAl explosives, but may also serve as reference for the study of new composite explosives.
