Aerospace Engineering

Week two – “Aerospace Engineering” ended with two amazing lectures presented by Raycho Raychev and Stanimir Gantchev.

Raycho gave a talk on “Satellite Technology”. He described the three main segments of a space system: ground, launch and space. Don’t forget the formula: Spacecraft = Payload + Bus

Raycho explained in details by which subsystems a bus is composed of and didn’t miss the chance to challenge the cadets with some interesting questions.

The lecture of Stanimir was on the topic of “Introduction to Satellite Engineering”. In the beginning he explained the CubeSat design specification and applications. Soon after that he asked the cadets to describe the vital subsystems of a satellite bus.

Stan gave a very detailed description of satellite engineering phases. He went from Phase 0 (CDF Study) to Phase F (De-orbiting).

After that Stanimir talked about the project’s design document and showed a nice photo of Sputnik 1. He did not forget to mention the importance of the mass, power & link budgets.

Stan concluded his lecture by telling the cadets how important brainstorming is, for a project to be successful. He was determined to make them all understand the significance of efficient teamwork. Here are some of his motivating phrases during the lecture:

Work as a team! Plan your activities. The final result matters! It is important to have a strong team, not strong individuals. Do not be afraid to prototype and test. May the force be with you!

After that the cadets had their first workshop. They were organized in space teams and were ready to start working hard on their prototypes. The workshops take place in Betahaus where the participants have dedicated co-working space. The second workshop was about the mission objectives of each project, as well as the team requirements. The next step is the design and engineering of all prototypes… looking forward!
