... '' A variational approach is given to fundamental principles of dynamics, showing how these principles can be applied to space problems. Techniques for dynamical analyses are developed in such areas as coordinates for ... optimization. Individual chapters deal with kinematics, transformation of coordinates, gyrodynamics, dynamics of gyro instruments, space vehicle motion, performance and optimization, and generalized theories of mechanics. Extracted from the 1962 Publication ''Annotated Bibliography ...

Established initially by Nikolai I. Tikhomirov in March 1921, the Gas Dynamics Laboratory evolved from early smokeless powder propellant experiments made by Tikhomirov in Moscow. By 1925, ... successful launchings the rocket laboratory was considerably expanded, and in July 1928 named the Gas Dynamics Laboratory (GDL). The laboratory, the first in the Soviet Union to be engaged in rocketry ...
