Good luck getting a helicopter hypersonic. You need more than 2,600 m/s to escape Titan. The speed of sound on Titan is 194 m/s.

The RTG makes heat, which is used in two ways in missions to cold places: Through thermocouples to generate electricity, and through waste heat. Some of the waste heat is cycled through coolant loops or heat pipes to keep things warm; the excess is radiated. The electricity can also be used to run heaters. As the RTG ages and the plutonium within it ...

The problem here is that you are comparing a nuclear "battery" with a conventional battery. A conventional battery you draw power from it at whatever rate you want (up to some limit based on the battery) until it's gone, then it produces nothing. However, nuclear "batteries" are a very different beast. They're actually generators, not ...

It's a good question, but no it's not possible. The denser atmosphere works for you and against you, for you in that you can achieve more lift with less blade or a slower blade rotation, against you because it also increases drag which will slow the craft and it's blades. But, regardless of density this won't work because of the basic mechanics of ...

There is a maximum height for the helicopter. If the lift force of the rotor is equal to the weight of the helicopter it could not get higher. If you go up with maximum speed you only get a little jump above the maximum height but very soon the helicopter will be down at maximum height again. The escape velocity of Titan is 2.639 km/s. A helicopter with ...

Titan's atmosphere is has about 1.5 times the surface pressure of Earth's, so there would be no need for a pressure suit and it's mainly nitrogen, so not especially toxic. Something like a divers' dry suit would be a good place to start. You would need to find a material for the suit that remained flexible at low temperatures, which might be a challenge, and ...
