Description

Technical Field

[0001] The present invention relates to the technical field of transportation vehicles, and particularly to a flying car with dual-chamber gas conversion and nuclear-powered hydrogen propulsion. Background Art

[0002] With the acceleration of the urbanization process, ground traffic congestion has become a global problem. Traditional solutions such as road expansion and public transportation optimization have limited effectiveness, and three-dimensional transportation has become an important development direction. Flying cars, due to their three-dimensional space passage ability, are regarded as a revolutionary technology to relieve traffic pressure. However, existing flying car technologies still face multiple bottlenecks. For example, current mainstream solutions rely on lithium batteries or traditional fuels. Lithium batteries have a low energy density, generally lower than 300 Wh / kg, resulting in short flight endurance. For example, most prototypes have an endurance of less than 1 hour. Although fossil fuels have a high energy density, they have prominent carbon emission problems, and the energy consumption during vertical takeoff and landing is huge, with poor economy.

[0003] In summary, there is an urgent need for a flying car solution that integrates efficient energy conversion to break through the bottlenecks of existing technologies and promote the practical application of urban three-dimensional transportation. Summary of the Invention

[0004] The purpose of the present invention is to provide a flying car with dual-chamber gas conversion and nuclear-powered hydrogen propulsion to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A flying car with dual-chamber gas conversion and nuclear-powered hydrogen propulsion, comprising: A vehicle body; Two independent sealed chambers are provided inside the vehicle body, storing gaseous hydrogen and liquid hydrogen respectively, and there is a conversion device for converting hydrogen into liquid and vice versa to realize the lifting of the car; A nuclear-hydrogen power system, composed of a nuclear reactor power supply system and a hydrogen power propulsion system. The nuclear reactor power supply system uses a small nuclear reactor to provide a power source, and the hydrogen power propulsion system uses the energy generated by the small nuclear reactor to drive the thrusters to control the speed and direction of the car; A driving and control system is provided at the front of the vehicle body, which can transmit the operation instructions of the driver to the total control system; The total control system coordinates the instructions between the nuclear-hydrogen power system and the driving and control system, and analyzes and judges to ensure the safety of lifting and driving.

[0008] Preferably, the nuclear reactor power supply system includes a radiation level detection system and a cooling system detection system. The radiation level detection system is used to monitor the radiation dose during the operation of the nuclear reactor in real time to ensure that the radiation leakage of the equipment is controlled within the safety threshold.

When the monitored value exceeds the safety threshold, the radiation dose overlimit alarm triggers an audible and visual alarm.

[0012] Preferably, both the nuclear reactor radiation level detection system and the cooling system detection system have a fault redundancy design, adopting a triple redundant circuit, and any two signal anomalies trigger a response.

[0013] Preferably, the hydrogen-powered propulsion system includes a thruster and a combustion control system.

[0014] Preferably, a multi-layer protective layer structure is further provided outside the nuclear reactor.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through three core designs of hydrogen state conversion for lifting and lowering, continuous hydrogen supply driven by nuclear energy, and dynamic coordination of the total control system, the present solution constructs a flying car with dual-chamber gas-liquid conversion and nuclear energy hydrogen power. The body of the car is made of carbon fiber material, which can effectively reduce the overall weight of the car. Detailed implementation mode

[0016] Example 1:

[0017] The present invention provides a technical solution: A flying car with dual-chamber gas conversion and nuclear energy hydrogen power, comprising a body, a nuclear energy-hydrogen power system, a driving and control system, and a total control system. The body is manufactured by an advanced carbon fiber manufacturing process. The carbon fiber prepreg is laid, formed, and cured according to the designed body shape to ensure the body strength while minimizing the weight to the greatest extent.

[0018] Two independent sealed chambers are provided inside the body to store gaseous hydrogen (upper chamber) and liquid hydrogen (lower chamber) respectively. The chambers are connected by high-pressure resistant pipes, and there is a conversion device for converting hydrogen into liquid and vice versa to realize the lifting and lowering of the car; the conversion device in the dual-chambers includes a compressor, a heater, and an electromagnetic valve group. The compressor is used to compress gaseous hydrogen into liquid and inject it into the lower chamber, the heater is used to vaporize liquid hydrogen and return it to the upper chamber, the compressor and the heater are powered by the nuclear reactor energy supply system, and the electromagnetic valve group is used to control the flow direction and rate of gas and liquid between different sealed chambers, as well as the exchange with the outside world. Specifically, the opening degree is adjusted by the total control system, and the gas-liquid hydrogen flow is dynamically distributed according to the lifting and lowering requirements.

[0019] The lifting and lowering modes of the car are as follows: Descending mode: The compressor starts, compresses the gaseous hydrogen in the upper chamber into liquid and injects it into the lower chamber, then the total mass of the car increases, and it sinks under the action of gravity.

[0020] Ascending mode: The heater starts, vaporizes the liquid hydrogen in the lower chamber and returns it to the upper chamber, the total mass is reduced, and it is driven to rise by the thrust of the thruster.

[0021] The nuclear energy-hydrogen power system consists of a nuclear reactor power supply system and a hydrogen power propulsion system. The nuclear reactor power supply system uses a small nuclear reactor designed with a high-temperature gas-cooled reactor, with helium as the coolant and uranium-235 in the form of coated particles as the fuel. Thermal energy generated by nuclear fission drives a steam turbine to generate electricity, and the electricity is supplied to an electrolyzer to decompose water to produce hydrogen as a power source. Before startup, the nuclear reactor undergoes strict safety inspections, including radiation level detection and cooling system detection. During operation, the output power of the reactor is precisely adjusted through the master control system to meet the hydrogen production requirements under different working conditions.

[0022] Specifically, the radiation level detection system is used to monitor the radiation dose during the operation of the nuclear reactor in real time to ensure that the radiation leakage of the equipment is controlled within the safety threshold; the cooling system detection system is used to monitor parameters such as the temperature, flow rate, and pressure of the coolant in the nuclear reactor to ensure that the heat dissipation efficiency meets the standard and prevent the core from overheating and melting down.

[0023] The radiation level detection system includes a radiation detector array and an alarm and control unit.

[0024] The radiation detector array includes gamma-ray detectors: arranged in the outer shielding structure of the reactor and the personnel activity area (such as the cockpit), using bismuth germanate (BGO) crystal detectors or sodium iodide (NaI) scintillators combined with photomultiplier tubes. And neutron detectors: arranged near the neutron reflector layer of the reactor, using boron trifluoride (BF 3 3) proportional counters or lithium glass scintillators.

[0025] The alarm and control unit includes a radiation dose overlimit alarm: when the monitored value exceeds the safety threshold, such as the cockpit radiation > 0.1 mSv / h, an audible and visual alarm is triggered. And an automatic shutdown interlock device: when a serious leakage is detected, such as the reactor surface radiation > 10 mSv / h, the nuclear reaction chain reaction is automatically cut off, and a standby power supply is started for core cooling.

[0026] The cooling system detection system includes a multi-level temperature monitoring module, a fluid state monitoring unit, and a heat dissipation structure safety monitoring.

[0027] The multi-level temperature monitoring module includes a core temperature probe: using a tungsten-rhenium thermocouple with a maximum temperature resistance of 2000 °C, embedded in the fuel rod gap of the reactor. And a coolant inlet and outlet temperature difference sensor: a dual-redundant platinum resistance (Pt100) temperature probe, placed in the main cooling circuit pipeline.

[0028] The fluid state monitoring unit includes a liquid metal flowmeter: if a sodium-cooled reactor is used, an electromagnetic flowmeter is used to measure the liquid sodium flow rate, such as the range: 3 - 8 m / s. And a coolant pressure sensor: a piezoelectric ceramic sensor, arranged at the outlet of the main pump, such as the working pressure range: 15 - 30 MPa.

[0029] The safety monitoring of the heat dissipation structure includes an infrared imaging system for the temperature of the heat sink: the surface temperature distribution of the heat dissipation fins is monitored in real time through an infrared camera. And a heat pipe failure detector: the abnormal phase change of the working fluid inside the heat pipe is detected through a vibration sensor.

[0030] In addition, an abnormal handling mechanism is also provided. For minor faults (such as a 20% reduction in the coolant flow rate): the power of the auxiliary circulation pump is automatically increased. For serious faults (such as a 10% sudden increase in the core temperature): the emergency spray system is started to inject nitrogen into the core, and at the same time, the nuclear fission reaction is cut off.

[0031] Both the above-mentioned nuclear reactor radiation level detection system and the cooling system detection system have a fault redundancy design, adopting a triple-redundancy circuit, and any two signal abnormalities will trigger a response.

[0032] For example, when the γ-ray detector outside the reactor detects that the radiation dose exceeds the safety threshold and the radiation exceeds the standard, an alarm signal can be sent to the alarm and control unit, and then the compensation control rod will immediately insert into the core to reduce the radiation level below the safety threshold.

[0033] The hydrogen-powered propulsion system includes 4 groups of vertical lift thrusters arranged at the bottom of the vehicle body and 2 groups of horizontal thrust thrusters at the tail, as well as a combustion control system. After hydrogen and air are mixed and ignited, the opening of the hydrogen injection valve is adjusted through the combustion control system to dynamically adjust the thrust magnitude and direction of the thrusters, thereby controlling the speed and direction of the vehicle.

[0034] The driving and control system is provided with a driving controller at the front of the vehicle body, which can convert the operation instructions of the driver, such as acceleration, deceleration, steering, etc., into electrical signals and transmit them to the total control system through the bus, so as to accurately adjust the supply amount of hydrogen and the working state of the thrusters to ensure the smooth operation of the vehicle.

[0035] In addition, the total control system plays a coordinating and overall planning role. After receiving the driving instruction, it calculates the required lift / thrust, adjusts the opening of the double-chamber valve to control the hydrogen state conversion rate, distributes the output power of the nuclear reactor to the electrolyzer and the thrusters, and at the same time, if hydrogen leakage or radiation exceeding the standard is detected, the power is immediately interrupted and an emergency landing is started to ensure flight safety.

[0036] When in use, the flying car realizes normal flight work through the following several stages: Takeoff stage: The total control system starts the heater, and the liquid hydrogen is converted into gaseous state, filling the upper chamber, reducing the mass; the bottom thrusters output at full power and vertically lift off to the target height.

[0037] Cruise stage: The horizontal thrusters adjust the thrust direction according to the steering wheel commands to achieve forward movement / turning; the dynamic balance of the dual-chamber hydrogen state is maintained to keep the flight altitude stable. Retractable wings can be installed on both sides of the vehicle body. During the cruise stage, the aerodynamic lift is used to assist in maintaining the altitude, reducing the hydrogen conversion frequency. The total control system adjusts the thruster thrust in real time based on the mass change and combines with the inertial navigation system (INS) to ensure flight stability. Reference can be made to the existing technology here.

[0038] Landing stage: The compressor starts, and gaseous hydrogen is converted into liquid, enters the lower chamber to be filled, and the mass increases; the power of the bottom thrusters decreases, and gravity dominates the slow descent.

[0039] In actual application, there will also be multiple protective layer structures outside the nuclear reactor. For example, the innermost layer is made of ceramic materials that are resistant to high temperatures and corrosion, the middle layer is a shielding layer made of lead alloy for shielding nuclear radiation, and the outermost layer is a high-strength carbon fiber composite material shell that can resist external impact forces and ensure the safe operation of the nuclear reactor reaction. This will not be elaborated here.

[0040] The above designs, such as real-time monitoring at multiple levels and redundant protection measures, ensure the safe operation of the nuclear energy system in the environment of a flying car. In actual engineering applications, international nuclear safety standards (such as IAEA SSG-39) and aerospace-level reliability requirements must be strictly followed.
