Can We Combine Solar Sails and Ion Thrusters for Faster Space Travel?

AI Thread Summary
Combining solar sails with ion thrusters for faster space travel is a topic of interest due to the potential advantages of both propulsion methods. Solar sails provide a constant push from solar radiation, while ion thrusters offer speed and maneuverability. However, challenges arise in integrating these systems, particularly regarding spacecraft weight; solar sails require extremely lightweight designs to be effective, which may be compromised by additional propulsion systems. A theoretical solar sail made of ultra-thin aluminum could enable rapid travel to nearby stars, but practical obstacles remain in building and deploying such technology. Overall, while the concept is intriguing, significant engineering challenges must be addressed to make it feasible.

I've heard a lot of people talk about solar sails versus things like Ion thrusters, and it seems that both have their advantages and disadvantages. So I was wondering whether or not it's possible to use both on a single spacecraft ? That way you could get the speed of an ion thruster along with that constant push of the solar sail... Is this possible?

I guess what I'm thinking is something like one of those sail boats on Earth that also has a few engines on board. I know this is a completely different animal, but that's the same general idea, I think. I don't sail, so I'm not sure.

Doesn't necessarily have to be Ion Thruster, I just want to know about using solar sails along with any other, more "traditional", propulsion method on a spacecraft .
 
Solar sails need extremely light spacecraft to be effective. I'm not sure if that scales well enough to combine it with other propulsion methods (=more mass) - the sail would have to be extremely large to give a notable effect.

I once saw an article that described a solar sail made of aluminum, only two atoms thick, but a diameter the size of The Moon. It would weigh only one gram. Carrying a four gram payload, and boosted to 0.3 c with lasers it could reach the nearest star in only a few years, then beam back a selfie.

The only obstacles are building and deploying a system like that. Lots of luck.

P.s. The autocorrect on my iPad tried to change "nearest star" to "nearest Starbucks,". If I posted that, you would have all had a chuckle at my expense.
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
