In summary, Space X's decision to not use a foldable rotor and instead focus on improving engine throttling for efficient landing is a sound choice for their goal of building a reusable rocket.

Space X wants to build such a reusable rocket:
Why don't they instead use a foldable rotor and land the thing with autorotation?
I mean it wouldn't take any fuel.

There was one contender that had such a design, but they dropped out early in the competition.
Do note that the rotor idea has some disadvantages, as it adds the dead weight of large hinged blades and their attachments, plus unpowered it has very limited maneuverability.
The Space X reusable booster requires very little fuel, as the empty booster is a fraction of the weight of the full unit. Throttling the engine efficiently is the biggest challenge, but if that is achieved, landing for reuse is a realistic option.

While using a foldable rotor and autorotation may seem like a cost-effective solution, it may not be practical for a reusable rocket like Space X wants to build. First of all, the size and weight of the rotor needed to support the rocket's landing would be significant, making it difficult to maneuver and control during descent. Additionally, the added weight of the rotor would require more fuel to launch, counteracting the savings from not using fuel for landing. Furthermore, the complexity of integrating a rotor system into the rocket's design would also increase the cost and potential for malfunctions. Space X's current approach of using thrusters for landing has proven to be successful and allows for more precise control during descent. While it may require some fuel, it is a more practical and reliable option for reusable rockets.
 

1. What is an autogyro reusable rocket?

An autogyro reusable rocket is a type of rocket that uses a rotor system to generate lift and propulsion, similar to a helicopter. It is designed to be reusable, meaning it can be launched multiple times without needing major repairs or refurbishment.

2. How does an autogyro reusable rocket work?

The rocket uses a rotor system to generate lift and thrust, which allows it to take off and land vertically. Once in the air, the rotor system is used to maintain lift while the rocket's engines provide horizontal propulsion. The rocket's wings also provide additional lift and control during flight.

3. What are the advantages of an autogyro reusable rocket?

The main advantage of an autogyro reusable rocket is its reusability. This reduces the cost of spaceflight by eliminating the need to build a new rocket for each launch. Additionally, the vertical takeoff and landing capabilities of the autogyro design allow for more flexibility in launch locations and reduce the need for large launch facilities.

4. What are the potential applications of an autogyro reusable rocket?

An autogyro reusable rocket could be used for a variety of space missions, including satellite launches, cargo transportation to and from space stations, and even human spaceflight. Its versatility and reusability make it a promising option for reducing the cost and increasing the accessibility of space exploration.

5. What challenges need to be overcome for the successful use of an autogyro reusable rocket?

One of the main challenges is developing a reliable and efficient rotor system that can withstand the extreme conditions of spaceflight. Additionally, the rocket's engines and other components must be designed and tested for multiple launches. Safety and regulatory considerations must also be addressed before the rocket can be used for human spaceflight.
