In summary, the conversation discusses the possibility of using a ramp or rocket sled to reduce the amount of fuel used by rockets. While it may be possible, the idea comes with challenges such as finding a suitable location and increasing complexity.

Sure, it sounds silly, because it is. But would it work? Say, would the rockets use less fuel?

And yes, I'm horrible at starting threads.

If we had a long enough, strong enough ramp, then maybe. However, the ramp would have to be so steep that it'd hardly be worth using when it's possible for a rocket to take off vertically.
So to answer your question, it could be possible, but it would not be worthwhile.

There are some ideas. Even a rocket sled could help, if you can refuel and reuse the sled easily. First stages burn fuel in the range of tons/second, if you can accelerate the rocket on a ramp for 10-20 seconds the rocket can get much smaller and cheaper or carry more payload at the same size.
The downside is the increased complexity, and you need some large mountain nearby.

1. How does launching spacecraft with ramps work?

Launching spacecraft with ramps involves using a sloped structure to accelerate the spacecraft to a high speed before it leaves the ramp and enters space. The ramp is usually angled at a specific degree to achieve the necessary velocity for the spacecraft to overcome Earth's gravitational pull.

2. What are the advantages of using ramps for launching spacecraft?

One advantage of using ramps for launching spacecraft is that it requires less fuel compared to traditional rocket launches. This is because the ramp provides some of the initial acceleration, reducing the amount of fuel needed for the spacecraft to reach escape velocity. Additionally, ramps can be built on sloped terrain, making it easier to find suitable launch locations.

3. What materials are used to construct spacecraft ramps?

The materials used to construct spacecraft ramps vary depending on the specific design and location. Some common materials include concrete, steel, and reinforced composites. These materials must be able to withstand extreme temperatures, pressures, and forces during the launch process.

4. How is the angle of the ramp determined?

The angle of the ramp is determined based on the specific spacecraft being launched and the desired velocity. Engineers use mathematical calculations and simulations to determine the optimal angle for the ramp to achieve the necessary speed for the spacecraft to reach orbit.

5. Are ramps used for all spacecraft launches?

No, ramps are not used for all spacecraft launches. They are typically used for smaller spacecraft or payloads, as they are not capable of launching larger and heavier spacecraft. Additionally, ramps may not be suitable for launches to specific orbits or destinations that require a different trajectory.
