Description

Technical Field

[0001] This invention relates to the field of rocket passive propeller energy storage technology, and in particular to a method for energy storage of the passive propeller of the PD-9S rocket engine. Background Technology

[0002] Current manned rocket engines mainly adopt active propeller drive, which uses external energy to drive the propeller to rotate. By precisely controlling the rotation speed and direction of the propeller, various flight missions and maneuvers can be achieved.

[0003] However, this method requires a large amount of fuel and has problems such as complex and easily damaged structure, difficulty in attitude control, and poor safety.

[0004] Therefore, it is necessary to find a new method for storing energy in the passive propeller of a rocket engine that can improve both rocket performance and safety, thereby meeting the power, safety, and economic requirements of passenger rockets. Summary of the Invention

[0005] The purpose of this invention is to provide an energy storage method for the passive propeller of the PD-9S rocket engine, which solves the problems of complex structure, easy damage, difficult attitude control, and poor safety of active propeller drive.

[0006] To achieve the above objectives, the present invention provides a method for energy storage of the passive propeller of the PD-9S rocket engine, comprising the following steps: The rocket launch generates a large amount of high-speed exhaust gas, which passes through the propeller blades and drives the propeller to rotate. The propeller rotates, storing rotational kinetic energy; The rotational kinetic energy is converted into electrical energy; The electrical energy is stored; When the rocket is restarted, the stored electrical energy is converted into thrust to supply the rocket, enabling the rocket to operate continuously.

[0007] The rocket launch generates a large amount of high-speed exhaust gas, which drives the propeller blades to rotate. Prior to this step, the following steps are also included: The propeller blades and root are manufactured using a lightweight integrated design made of metal-ceramic materials and additive manufacturing technology. Install the propeller at the tail of the rocket; After installation, the propeller was tested and verified to ensure that it could effectively capture the kinetic energy of the rocket exhaust to make itself rotate.

[0008] The process of manufacturing propeller blades and roots using lightweight integrated design with metal-ceramic materials and additive manufacturing technology also includes: A cooling structure, including heat sinks and heat conduction grooves, is designed inside the propeller blades.

[0009] The step of converting the rotational kinetic energy into electrical energy further includes: Choose an appropriate generator; When the propeller rotates, its power is transmitted to the generator through the drive shaft, generating an induced electromotive force. The induced electromotive force is converted into direct current by a rectifier; The voltage of the DC power is regulated.

[0010] The step of storing the electrical energy further includes: The regulated electrical energy is then sent to an energy storage device for storage. Energy management is carried out during the energy storage process.

[0011] When the rocket is restarted, the stored electrical energy is converted into thrust to supply the rocket, enabling continuous operation. The steps also include: When thrust is needed to power the rocket, the stored electrical energy is released through a specific mechanism; Inside an electric motor or electrochemical engine, electrical energy is converted into mechanical or chemical energy; Mechanical or chemical energy is transferred to the propellant through the propulsion system. The propellant burns inside the rocket engine, producing high-temperature and high-pressure gas. The high-temperature, high-pressure gas generated by combustion is discharged through the nozzle at the tail of the rocket, generating thrust that propels the rocket forward.

[0012] This invention discloses an energy storage method for the passive propeller of the PD-9S rocket engine. During rocket launch, the propellant generates a large amount of high-speed exhaust gas. As the exhaust gas passes through the propeller blades at high speed, it generates a reaction force, driving the propeller to rotate. With launch, the propeller begins to rotate, storing a large amount of rotational kinetic energy. When the rocket stops supplying propellant, the propeller continues to rotate for a period of time. During this time, an energy conversion mechanism converts the propeller's rotational kinetic energy into electrical energy, which is then stored. When the rocket needs to be restarted, the stored energy can be converted back into propellant to supply the rocket, thus enabling continuous rocket operation. This method effectively solves the problems of energy utilization, safety, and thrust vector control in traditional rocket engines, improving the rocket's main thrust performance, attitude control performance, green energy, and safety, meeting the power, safety, and economic requirements of passenger rockets.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 2 The present invention relates to a process in which a large amount of high-speed exhaust gas is generated during rocket launch, and the exhaust gas passes through the propeller blades to drive the propeller to rotate.

Figure 4 This is a diagram illustrating the steps of storing electrical energy according to the present invention. Figure 5 This invention illustrates the steps of converting stored electrical energy into thrust to supply the rocket during restart, enabling continuous rocket operation. The invention also provides a method for storing energy in the passive propeller of the PD-9S rocket engine, comprising the following steps: S101: The rocket launch generates a large amount of high-speed exhaust gas, which drives the propeller to rotate through the propeller blades; S1011: The propeller blades and root are manufactured using a lightweight integrated design with metal-ceramic materials and additive manufacturing technology. S1012: Install the propeller at the tail of the rocket; S1013: After installation, the propeller is tested and verified to ensure that it can effectively capture the kinetic energy of the rocket exhaust to make itself rotate.

[0022] Specifically, during rocket launch, propellant burns inside the rocket engine, generating a large amount of high-temperature, high-pressure gas. This gas is ejected at high speed through the rocket's exhaust nozzle, forming the rocket's exhaust. A passive propeller is installed at the rocket's tail. When the rocket's exhaust flows over the propeller, it is propelled by the gas and begins to rotate. The exhaust nozzle's outer shell features a regenerative cooling channel to ensure the mechanical stability of the nozzle material at high temperatures. The propeller blades and root are manufactured using a lightweight, integrated design of metal-ceramic materials and additive manufacturing technology. The blades incorporate an internal cooling structure. After installation, the propeller undergoes testing and verification to ensure it functions correctly during rocket launch, effectively capturing the kinetic energy of the rocket's exhaust to rotate. Finally, acceptance testing is conducted to ensure the propeller installation meets requirements.

[0023] S102: The propeller rotates, storing rotational kinetic energy; S103: Convert the rotational kinetic energy into electrical energy; S1031: Select an appropriate generator; S1032: When the propeller rotates, its power is transmitted to the generator through the drive shaft, generating an induced electromotive force; S1033: The induced electromotive force is converted into direct current by a rectifier; S1034: Regulate the voltage of the DC power supply.

[0024] Specifically, selecting an appropriate generator is crucial for converting mechanical energy into electrical energy. There are many types of generators, such as permanent magnet generators and induction generators. Rotational kinetic energy is converted into mechanical energy inside the generator, which typically involves the rotation of one or more rotating shafts. One end of the shaft is connected to the generator. Inside the generator, the design of the magnetic field and coils ensures that when the rotating shaft drives the coil to rotate, the coil cuts the magnetic field, generating an induced electromotive force. This process is an application of the principle of electromagnetic induction. The generated induced electromotive force is directly output as electrical energy. To adapt to different application requirements, the voltage needs to be regulated or rectified to ensure that it meets the load requirements.

[0025] S104: Store the electrical energy; S1041: The regulated electrical energy is sent to an energy storage device for storage; S1042: Energy management is carried out during the energy storage process.

[0026] Specifically, the converted electrical energy can be directly supplied to the load or stored in energy storage devices, such as batteries or supercapacitors. For scenarios that require energy storage, an energy management system is used to monitor the status of the energy storage device, control the energy input and output, and ensure the safety and efficiency of energy storage. When the stored electrical energy needs to be released, the energy management system coordinates the energy exchange between the energy storage device and the load.

[0027] S105: When the rocket is restarted, the stored electrical energy is converted into thrust to supply the rocket, enabling the rocket to operate continuously.

[0028] S1051: When thrust is needed to power the rocket, the stored electrical energy is released through a specific mechanism; S1052: Inside an electric motor or electrochemical engine, electrical energy is converted into mechanical or chemical energy; S1053: Mechanical or chemical energy is transferred to the propellant through the propulsion system. The propellant burns inside the rocket engine, producing high-temperature and high-pressure gas. S1054: The high-temperature and high-pressure gas generated by combustion is discharged through the nozzle at the tail of the rocket, generating thrust, which propels the rocket forward.

[0029] Specifically, when thrust is needed to power a rocket, stored electrical energy is released through a specific mechanism. This may involve the activation of one or more electric motors or electrochemical engines. Inside these engines, electrical energy is converted into mechanical or chemical energy to drive the rocket's propulsion system. The technology involved in this process depends on the type of engine used. The mechanical or chemical energy is transferred to the propellant through the propulsion system. The propellant burns inside the rocket engine, producing high-temperature, high-pressure gas. This gas is expelled through nozzles at the rocket's tail, generating thrust that propels the rocket forward. During launch and flight, the rocket's attitude needs to be adjusted. By controlling the thrust and direction of the propulsion system, attitude adjustment and maneuvering are achieved. Throughout the conversion and propulsion process, sensors and control systems are used to monitor the rocket's status and performance parameters. This data can be used to adjust the operation of the propulsion system in real time, ensuring a safe and accurate launch.

[0030] It effectively solves the problems of traditional rocket engines in terms of energy utilization, safety, and thrust vector control, improves the main thrust performance, attitude control performance, green energy and safety of rockets, and meets the power, safety and economic requirements of passenger rockets.
