What significant contribution did Jean Froissart make to rocketry?

Jean Froissart made a significant contribution to rocketry by improving accuracy through the innovation of launching rockets through tubes. This technique allowed for better guidance and control during the initial phase of flight, reducing the erratic behavior that often plagued early rocketry. By channeling the rocket's propulsion within a confined space, Froissart ensured that the rockets would have a more predictable trajectory and improved aerodynamic stability upon launch.

This idea of using tubes not only increased accuracy but also provided a more repeatable method of launching rockets, which was essential for military and experimental applications. The concept laid the groundwork for later advancements in guided missile technology, where precision and reliability are paramount.
