Rocket Propulsion (1)|2023 LATEST UPDATE|GUARANTEED SUCCESS

1. Which of Newton's Laws describes how a rocket works? Action - Reaction: Newton's Third Law 2. Explain the difference between Thermodynamic and Electrodynamic propulsion systems used on spacecraft --Thermodynamic (heat/pressure energy) i. Cold gas ii. Liquid chemical Monopropellant Bipropellant iii. Solid chemical iv. Hybrid chemical v. Nuclear thermal vi. Arc-jet vii. Resisto-jet viii. --Electrodynamic (electromagnetic energy) i. Ion thruster ii. Plasma rocket 3. What is the most common type of thruster used for satellite on-orbit propulsion and attitude control? Monopropellant Liquid chemical Can throttle and restart Very high thrust Cons Not Storable on rocket Complex Expensive Explosive hazard Solid chemical Simple and storable Very high thrust Inexpensive Can't throttle Can't stop/re-start Difficult to vector thrust Explosive hazard Low ISP
