Syllabus of lectures:

1) Space Launch Vehicles Architecture I: history, the classification of the launch vehicles (expendable, reusable, single-stage, multi-stage, type of propellant, payloads, manned/unmanned), the subsystems of the launch vehicles.

2) Space Launch Vehicles Architecture II: the construction ofthe single-staged or multi-staged launch vehicles, the optimalisation of the stage numbers vs the chosen payload.

3) Space Launch Vehicles Architecture III: reusable vehicles, the review of the actually used launch vehicles, proposals of the new prospective launch vehicles.

4) Chemical Propulsion I: general survey, the thermodynamics of the chemical propulsion, the internal ballistics of rocket engines, the nozzle expansion processes, the thrust force of the rocket engine, the effective exhaust velcity, the specific impulse, the engine performance, the rocket engines using liquid and solid propellants, hybrid propellants.

5) Chemical Propulsion II: liquid propellant rocket engines-fundamentals, the combustion and possible vibrational instabilities, examples of oxidizers and fuels, the rocket engines construction pressure-fed, gas generator, staged combustion, expander), combustion of solid propellant.
