- Abstract
- A digitized measurement method was detailed for nozzle thrust line of solid rocket motor based on advanced non-contact measuring technology with laser radar. The principle of this measurement method and the self-calibration technology of tolling ball are deeply researched. It proposes a new measuring scheme for thrust line which aiming at the front and back face circularity, circular zero line and the inner 3-D shape of the motor nozzle. The thrust line is obtained through the proper optimization model, and experiment testing shows that this measurement method provides higher measuring precision and efficiency which ensure the accuracy of thrust line direction.
