Questions
1. Electrical power to accelerate a propellant by different possible electrical and/or magnetic means.(esa)
2. An Electric Propulsion System is composed by four different building blocks: (esa)
2. An Electric Propulsion System is composed by four different building blocks: (esa)
- The thruster components,
- The propellant components or fluidic management system,
- The power components, which includes the PPU,
- The pointing mechanisms (optional)
5. Electrical propulsion is very fuel efficient and needs less than most other rockets.
conclusion questions
1. Newton's third law states that for every action, there is an equal and opposite reaction. Modern ion thrusters use inert gases for propellant.
