Description
Technical Field
[0001] This invention relates to the field of booster rocket launch technology, and in particular to a steam-powered rocket booster launch device and its launch method. Background Technology
[0002] With the development of the space industry, low-cost reusable rocket launches have become a research hotspot. Currently, most space launch missions employ a vertical static launch method without external boosters, meaning the rocket engine ignites at zero velocity, relying entirely on its own power to overcome gravity for liftoff. During liftoff, the rocket's overall weight is significant, requiring the rocket engine to provide sufficient thrust, typically operating at full load to achieve maximum thrust performance, placing the engine in an extreme high-temperature, high-pressure environment. When launching reusable rockets, these operating conditions significantly shorten the lifespan of critical components in the rocket engine system, increase maintenance difficulty, severely restrict the rocket's reusability, and hinder further cost reductions in space launches. Therefore, booster launch technology is needed to assist rocket launch and liftoff, reduce engine load pressure, and improve system reliability and reusability.
[0003] Currently, booster launch schemes are mainly based on electromagnetic catapults, pneumatic catapults, and air launches. Although these methods can increase the initial velocity of rockets to some extent, they generally suffer from limited thrust, complex structures, and high operating costs, making them particularly difficult to apply in heavy-lift rocket launches. Therefore, there is a need for a booster launch technology that is relatively simple in structure, provides high thrust, is low-cost, safe and reliable, and suitable for high-frequency launch missions. This invention will utilize high-pressure steam to provide a novel steam-assisted launch technology scheme that features high thrust, low cost, high reusability, safety and environmental friendliness, and is adaptable to high-frequency rocket launch missions. This is of great significance for improving the launch efficiency and reliability of future rockets. Summary of the Invention
[0004] In view of this, the present invention provides a ground-based vertical boost launch method and launch device based on steam power. Using this launch technology can effectively improve rocket launch efficiency, reduce rocket engine workload, and improve the reliability of reusable rockets.
[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: a steam-powered rocket booster launch device, comprising: a launch tower, a booster base, multiple mechanical clamping arms, and a steam supply mechanism.
[0006] The launch towers are two in number and are distributed opposite each other on both sides of the rocket. Each of the two launch towers has a sliding groove on its opposite sides. The booster base is placed at the bottom of the rocket and its opposite ends slide in the two sliding grooves. Multiple steam nozzles A are fixed at intervals at the bottom of the booster base. Multiple mechanical clamping arms are clamped on the outside of the rocket above the booster base and their opposite ends slide in the sliding grooves. Steam nozzles B are fixed at the bottom of the multiple mechanical clamping arms. Multiple steam outlets of the steam supply mechanism are connected to the multiple steam nozzles A and multiple steam nozzles B.
[0007] The beneficial effects of this invention are:
[0008] 1. By utilizing a steam supply mechanism to provide high-temperature, high-pressure steam to multiple steam nozzles A and B, a greater initial velocity can be provided to the rocket during the launch phase, reducing the workload of the rocket engine during takeoff, improving the vertical takeoff and launch efficiency of existing rockets, enhancing engine reliability and reusability, and reducing rocket launch costs. Simultaneously, the rocket booster launch device of this invention has a simple structure, is easy to integrate, does not rely on complex electromagnetic or combustion drive systems, and has advantages such as high thrust, low cost, strong reusability, safety and reliability, and adaptability to high-frequency launch missions, significantly improving rocket launch efficiency and overall mission economy.
[0009] 2. This invention designs multiple mechanical clamping arms that can constrain the rocket's direction of motion while it moves vertically upward. The structure is relatively simple, easy to integrate, and has high boosting stability. It has high integration and reusability, and the device is highly modular, allowing for rapid loading, rapid reset, and rapid launch, greatly improving launch rhythm and launch site efficiency, and is capable of being used for flight-based launch missions.
[0010] 3. The present invention uses multiple steam nozzles A and multiple steam nozzles B to perform work, which then drop to ambient pressure and temperature. The resulting high-speed steam flow forms a protective gas film around the launch base. When the rocket ignites and takes off, it effectively isolates the high-temperature and high-speed gas ejected from the rocket engine, protecting the structural components, piping components, hydraulic components, and other infrastructure of the launch tower from the impact of the powerful heat flow. After each launch, a large amount of maintenance and repair work is saved.
[0011] 4. The rocket booster launch device designed in this invention stores a sufficient amount of high-pressure steam during rocket launch. In the event of a fire during rocket ignition, a large amount of steam can be rapidly ejected to extinguish the fire and protect the rocket and launch tower.
[0012] Based on the above technical solution, the present invention can be further improved as follows.
[0013] Furthermore, the steam supply mechanism includes a steam boiler, a steam energy storage controller, a steam accumulator, a steam distributor, and a sliding steam supply assembly. The steam boiler, the steam energy storage controller, the steam accumulator, the steam distributor, and the sliding steam supply assembly are connected in series via steam supply pipes. The sliding steam supply assembly slides on the tower, and multiple steam outlets of the steam supply mechanism are all located on the sliding steam supply assembly. The multiple steam outlets on the sliding steam supply assembly are respectively fixed on multiple steam nozzles A and multiple steam nozzles B.
[0014] The further beneficial effects of adopting the above are: by using a steam boiler, steam energy storage controller, steam accumulator, steam regulator and sliding steam supply assembly, high-energy steam with a pressure of over 20MPa and a temperature of over 800K can be generated to provide sufficient thrust to boost the rocket at the initial stage of takeoff, reduce the workload of the rocket's own engine, improve the problem of low takeoff efficiency and high engine load of traditional rockets from the source, and help improve engine reliability and reusability, and reduce rocket launch costs.
[0015] Furthermore, the sliding steam supply assembly includes a steam cylinder, a bottom cover, a piston, a sealing strip, and a steam distribution box. The tower has a groove on one side corresponding to the rocket. The steam cylinder is arranged along the height direction of the rocket and is embedded in the groove. The side of the steam cylinder corresponding to the rocket has an elongated hole penetrating its top and bottom ends. The bottom cover is sealed at the bottom end of the steam cylinder and has a sliding hole thereon. The piston slides and seals within the steam cylinder. The sealing strip slides and seals within the elongated hole, with its bottom end sliding through the sliding hole and its top end fixed to the piston. The steam distribution box is located outside the steam cylinder and fixed to the piston, and the steam distribution box communicates with the interior of the steam cylinder. Multiple steam outlets of the sliding steam supply assembly are all located on the steam distribution box.
[0016] The further beneficial effect of adopting the above is that by using the steam distribution box to provide high-temperature and high-pressure steam to multiple steam nozzles A and multiple steam nozzles B while moving with the rocket, the impact of steam supply on rocket boosting can be minimized.
[0017] Furthermore, it also includes two support frames, which are fixed to the booster seat on the two outer sides of the rocket and define a rocket restriction zone between the two support frames; the rocket is placed within the rocket restriction zone.
[0018] Furthermore, it also includes a booster controller, which is electrically connected to the plurality of mechanical grippers and the steam supply mechanism respectively.
[0019] Furthermore, it also includes a damping brake, which is fixed to the tower and can contact the mechanical gripper to restrict the mechanical gripper from continuing to move with the rocket.
[0020] The further beneficial effect of adopting the above is that by using a resistance device to quickly brake multiple mechanical clamping arms, multiple mechanical clamping arms can be stopped quickly, which facilitates the reset and reuse of multiple mechanical clamping arms.
[0021] Furthermore, all of the steam nozzles A and B are variable diameter pipes.
[0022] In addition, a method for rocket booster launch based on steam power is provided, including the aforementioned steam power-based rocket booster launch device, the specific steps of which are as follows;
[0023] S1. First, place the rocket vertically on the booster seat, and then clamp the rocket with multiple mechanical grippers that slide on the slide rails.
[0024] S2. First, high-temperature and high-pressure steam is generated using a steam boiler. This high-temperature and high-pressure steam is then injected into a steam accumulator, raising the pressure and temperature to a set threshold. Then, high-temperature and high-pressure steam is injected into multiple steam nozzles A and B.
[0025] S3. Under launch timing control, the high-temperature and high-pressure steam in the steam accumulator is released and enters multiple steam nozzles A and B through the steam supply device and is ejected downward to provide vertical thrust, which drives the rocket, booster and multiple mechanical clamping arms to move as a whole.
[0026] S3. Multiple mechanical clamping arms constrain the rocket's direction of motion, improving attitude stability;
[0027] S4. After the rocket reaches the predetermined initial velocity, it ignites. The steam supply mechanism begins to reduce the steam flow, and the booster and multiple mechanical grippers gradually decelerate. At the same time, the multiple mechanical grippers gradually release the rocket. Under its own power, the rocket flies away from the booster and multiple mechanical grippers and enters the autonomous flight phase.
[0028] S5. After the steam boosting stage is completed, the booster base and multiple mechanical clamping arms decelerate using damping brakes and return to their initial positions.
[0029] Furthermore, the high-pressure steam generated by the steam supply mechanism has a pressure of 20-30 MPa and a temperature range of 800-900 K.
[0030] Furthermore, the rocket ignites 0.3 to 0.5 seconds before the completion of the steam boost phase. Attached Figure Description
