The engineering aspects of satellites and their launching rockets

The paper discusses the different engineering problems associated with satellites and probes, and their launching rockets. The different set of operating conditions encountered in these two main areas of space technology are examined and the motive power and control problems which arise are dealt with. The basic requirements for the multi-stage launching rockets are discussed; rocket equipment at present under development is then reviewed, noting the limitations imposed by present rocket techniques and launching facilities. Future trends of rocket development are mentioned in relation to possible payloads. The composition of a typical satellite or space probe is then considered, with some attention being given to each of the different systems, such as structure, power, attitude and speed control, instrumentation and communication equipment, etc. Critical design criteria such as weight, and electrical power requirements are highlighted. The operating environment is then reiated to the choice of design of the various systems. Particular consideration is then given to several specific types of satellites and space probes, examining the differences which arise from the varied requirements, and assessing what integration may be achieved by the design of common systems for the various applications.
