, which would allow to establish a law of changing rocket motion in time. With the help of this device, he was able to determine the influence of the form and design of a rocket on its ballistic characteristics, thereby laying the foundations for calculated rocket designs. In 1849 he was appointed commander of the Petersburg Rocketry Department (Петербургское ракетное заведение). In 1861, he supervised the construction of a rocket factory in Nikolayev, which he would head six years later. Konstantinov is known to have created structurally perfect
