Abstract: Based on the analysis of the measuring principles and the structure of the strand burning rate apparatus (Light-Electricity type or Laser), a new method of light-electricity transformation for measuring the burning rate of solid propellants was raised. This method much improved the measurement accuracy, which has been verified by experimental results. Finally, the advantages of this method are discussed
