Day 4 - Thermal; Electrical Subsystems Flashcards
What subsystem regulates and maintains the temperature throughout the spacecraft?
Thermal Control Subsystem (TCS)
Direct sunlight, Albedo, and infrared are all examples of what kind of heat source?
External heat source
What is the biggest source of heat for orbiting spacecraft?
Direct sunlight
What is solar energy reflected by a planet?
Albedo
What is the thermodynamic system that cannot exchange either energy or matter outside the boundaries of the system?
isolated System
Planets, moons, and other large space bodies provide what type of external heat source?
Planetary Infrared (IR)
What is the transfer of heat between substances in direct contact?
Conduction
Heat transfer method where fluid is heated and transfers away from the heat source.
Convection
What is energy transfer via electromagnetic waves?
Radiation
*Only effective method to release heat from a spacecraft.
Batteries hold a charge longer when aligned in this configuration.
Parallel
Batteries aligned in this configuration are capable of more power.
Series
First battery used in space. Susceptible to memory effects.
Nickel Cadmium
