1. Calculation of the nominal flight path of the designed launch vehicle and analysis of its energy characteristics. 2. Perform trajectory design, optimization, and dispersion for suborbital and orbital launch vehicles. 3. Selection of the design characteristics of the launch vehicle for launching a given payload into a given orbit. 4. Calculation of derived launch vehicle parameters to determine the optimal way to optimize the design and increase the payload mass. 5. Evaluation of possible points of impact of the separating parts of the launch vehicle, calculation of the withdrawal trajectory of the upper stages. 6. Calculations of orbital maneuvers of the spacecraft (upper stage), including the flight to the Moon. 7. Calculation of the deployment of vehicles by an upper stage for a given angular distance. 8. Mathematical modeling and development of 6-DOF launch vehicle and spacecraft dynamics simulators. 9. Development of special software.
