There are several types of electric propulsion. None of these are useful for primary propulsion (getting off the ground and into orbit) because you can't deliver electric power at the enormous rate required. For orbital maneuvering, however, they can be very mass efficient. The sexiest is the ion thruster. It uses xenon gas, which is accelerated by electric grids. This was developed for stationkeeping of geostationary comsats, but also has seen use in deep space probes, see http://nmp.jpl.NASA.gov/ds1/tech/sep.html. The ion engine has a characteristic velocity of about 35 km/s, about ten times what you can get from typical thrusters. There are also resistojets, which heat the propellant with electricity, and plasma arc thrusters, which vaporize a block of Teflon with a big spark.

What did Tsiolkovsky prove?
Tsiolkovsky, a Russian scientist, is known for his work in astronautics and rocketry. He formulated the rocket equation, which describes the physics of rocket propulsion. His theories laid the foundation for space exploration and the development of rocket technology.
Why would a circuit not work when a wire is replaced with cotton string?
Cotton string does not conduct electricity, so replacing a wire with cotton string will break the electrical connection in the circuit. This will prevent the flow of electricity necessary for the circuit to work properly. It's important to use materials that conduct electricity, like wire, to maintain the circuit's functionality.
What position does the switch have to be in for a circuit to work?
The switch needs to be in the "on" position for the circuit to work, allowing the flow of electricity through the circuit. In the "off" position, the switch breaks the circuit, stopping the flow of electricity.
What type of elements would not be a good choice for use in electrical wiring?
Material that is not a good conductor of electricity, such as wood or plastic, would not be good choices for electrical wiring. Additionally, elements that are highly reactive or prone to corrosion, like sodium or mercury, would also be unsuitable for electrical wiring due to safety concerns.
What was Sir Isaac Newton's contribution to rocketry?
Sir Isaac Newton's contribution to rocketry was his formulation of the laws of motion and universal gravitation. These laws provided the foundation for understanding how objects move in space and the principles behind rocket propulsion. Newton's work laid the groundwork for the development of the science of rocketry.
Who was the father of modern rocket propulsion?
The father of modern rocket propulsion is considered to be Konstantin Tsiolkovsky, a Russian scientist and space pioneer who laid down the basic principles of rocket science. His work paved the way for the development of modern rocketry.
How does thrust work in the context of rocket propulsion?
Thrust in rocket propulsion is generated by expelling high-speed exhaust gases out of the rocket engine. This action follows Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. As the rocket expels gases downward, the reaction force pushes the rocket upward, creating thrust and propelling the rocket forward.
How did Robert Goddard invent rocket fuel?
Robert Goddard invented rocket fuel by experimenting with various combinations of liquid oxygen and gasoline in his rockets. Through trial and error, he discovered the optimal mixture that produced the most efficient propulsion for his rockets. Goddard's pioneering work laid the foundation for modern rocket propulsion systems.
What did Tsiolkovsky prove?
Tsiolkovsky, a Russian scientist, is known for his work in astronautics and rocketry. He formulated the rocket equation, which describes the physics of rocket propulsion. His theories laid the foundation for space exploration and the development of rocket technology.
How does Newton's Law of Motion apply to rockets?
Newton's laws of motion apply to rockets by explaining how propulsion, thrust, and control are necessary for a rocket to accelerate and navigate through space. The third law states that for every action, there is an equal and opposite reaction, which is the principle behind rocket propulsion. Rockets work by expelling mass in one direction to create an equal and opposite force that propels the rocket in the opposite direction.
What is the Pendulum Rocket Fallacy?
The Pendulum Rocket Fallacy is the belief that because a pendulum swings back and forth, a rocket can be designed to work in a similar way, changing its velocity by repeatedly turning its engines on and off. This comparison oversimplifies the complexities of rocket propulsion and dynamics, leading to misguided design concepts.
Who invented the rocket in victorian times?
Konstantin Tsiolkovsky, a Russian scientist and pioneer in astronautics, is often credited with laying the theoretical foundation for rocketry during the late 19th century Victorian era. While he did not actually invent the rocket, his work in rocket design and propulsion systems was influential in the development of the technology.
Would liferaft work on the moon?
I think so. The CO2 cartridge could also be used for propulsion
What parts make a rocket ship work outter space?
The main parts of a rocket ship that allow it to work in outer space include the propulsion system (engines), guidance system (to navigate in space), structural components (to withstand the forces of launch and flight), and life support systems (to sustain astronauts in space). Additionally, a rocket ship will typically have fuel tanks, rocket stages (for multi-stage rockets), and communication systems to stay in contact with mission control.
What rocket fuel did Robert goddard invent that you still use today?
Robert Goddard invented liquid fuel rockets, which are still used today in various forms for space missions and satellite launches. His work laid the foundation for modern rocket technology and propulsion systems.
How would an automobile work without electricity?
if it is a diesel
How does a quantum propulsion system work?
it probably doesn't
