Steam catapults need to be equipped with steam storage tanks, pipelines and auxiliary equipment, and are too large in size and weight.

According to the information obtained, the complete set of Eagle Sauce's latest steam catapult has a volume of 1,100 cubic meters and a total weight of nearly 500 tons.

This device consumes a lot of steam when working, and if it is ejected at a minimum interval of 2 planes per minute, after 16 minutes, the ejection will be too low because the steam pressure is too low, and it will consume 20% of the steam in the boiler, resulting in a decrease in the speed of the aircraft carrier.

Moreover, the efficiency of the conversion of this device into kinetic energy can be said to be very low, while the energy conversion efficiency of the electromagnetic catapult device is very high, and the volume of this complete electromagnetic catapult equipment is only one-third of the volume of the steam catapult device, and the total weight is only more than 200 tons.

This device shows very good performance after adding the high-power pulse power system, because the energy classification management and control technology is adopted, and the electromagnetic catapult device can continue to eject through this energy management technology after the completion of energy storage, and will not cause a huge load to the fuel cell power system terminal that provides energy, affecting the stability of the entire power supply network.

This is precisely one of the main reasons for the frequent problems after the electromagnetic catapult of Eagle Sauce is launched.

The ejection device needs to consume four megawatts of energy at a time, and the high-power pulsed power system that supports this system can store up to hundreds of megawatts of energy, which has great redundancy.

In fact, the R&D center has also simulated continuous ejection experiments, and the working time can exceed tens of minutes, but the drive module of the device will also produce a high temperature after working for so long, and it needs to be cooled in time, so it is impossible to work all the time, and there is no need for this.

The medium-voltage DC integrated power system developed by Professor Ma Weimin has overcome the problems of system short circuit and protection, and developed a fault branch fuse, which can successfully isolate the fault, operate normally in non-fault areas, and achieve selective protection.

In fact, the R&D center has carried out fault simulation after connecting this ejection system with other marine equipment power systems, and the fault branch fuse has also been successfully disconnected, marking that the medium-voltage DC integrated power system has broken through a key technical problem and can be fully utilized.

Of course, this system still needs to be tested a lot, because many problems will be exposed in the long test period, and various improvements and optimizations need to be made in the middle.

In addition, the catapult version of the aircraft must be redesigned and manufactured, and the existing version of the aircraft cannot be brought to this ejection device for experiments, which is a larger system project and also requires a lot of work to do.

However, now Huaxing Science and Technology Group Company and Naval University of Engineering have been able to do this in so many years, and he is still very satisfied.

In fact, a large number of technical patents and experience accumulated in this process have been used in many products and equipment of Huaxing Technology Group Company, and many technical patents are the world's top, which naturally benefits Huaxing Technology Group Company a lot.

Yang Jie then also inspected the electromagnetic blocking device that was being tested and verified.

In fact, it is not easy to come up with a set of electromagnetic catapult devices, and Yang Jie never thought of developing such a set of devices before, but the navy saw that it was going smoothly here, and it also added a burden to the R&D center, so that this R&D center still led the research and development of this set of blocking devices. 163

Since it is a task assigned by the state, it can only be done head-on.

The R&D center is mainly responsible for the overall design and development of electromagnetic blocking devices, and many other R&D institutions and enterprises have also joined in, after all, the number of design and R&D personnel in this area is not enough.

The development of this blocking device was started two years ago, but at that time, many key technologies had been overcome in the R&D center, so the research and development of this device was smoother than the electromagnetic catapult device.

In fact, the principle of electromagnetic ejection and blocking is the same as that of ejection, and the key technology is still in the motor technology and the key technology of the new blocking cable.

The blocking cable system developed by China itself before mainly adopts the hydraulic system, the blocking force of this system is relatively stiff, can not be accurately controlled, and the huge pulling force leads to the tail hook of the carrier-based aircraft and the body parts connected with the tail hook are easy to fatigue and age, shortening the service life of the carrier-based aircraft.

The most important thing is that this system has a relatively narrow limit on the weight and speed of the ship-based fighters, which makes the carrier-based aircraft have to release excess fuel and drop the ammunition to reduce the weight before landing safely, which obviously causes a lot of waste.

In fact, the navy was not particularly satisfied with the set of devices that had been successfully developed in China, and then launched the electromagnetic blocking project.

Because of the advantages of motor system technology, this system expands the range of landing weight and landing speed of carrier-based aircraft, which can meet the landing needs of a new generation of carrier-based aircraft with larger mass and faster speed, and at the same time is more compact.

This system can automatically set the tension peak of the arresting cable according to the different carrier-based aircraft, accurately control the load of the carrier-based aircraft tail hook and the position of the carrier-based aircraft on the deck, achieve precise control, help to extend the service life of the carrier-based aircraft, and can recover the drone.

In addition, more sensors are introduced into this device, which can grasp the operating status and wear of each subsystem component in real time, and can predict the remaining service life of the blocking cable and other components.

This system has a higher level of intelligence and automation, and has obvious advantages over the previous domestic arresting cable system.

The R&D center of this device has also passed many experimental verifications, and has also achieved the design goals, and is now undergoing experimental verification in terms of reliability and durability.

When the carrier-based aircraft lands, the throttle is in a state of afterburner, so the blocking cable must bear at least 20 times the impact force of the aircraft taking off, and if the arresting cable technology is more advanced, the more the carrier-based aircraft will want to land safely.

In fact, there are different opinions on the first time that this R&D center has made such a large energy level of high-power pulse power supply technology and equipment, as well as electromagnetic blocking and ejection devices, and some people even oppose it.

However, this R&D center is led by Huaxing Technology Group Company, and does not rely on state funding, and the R&D funds given by Huaxing Technology Group Company are very sufficient, and these R&D projects will not be interfered with.

Now seeing that these major R&D projects have come out one after another, the happiest thing is the navy, because these devices can catch up with the progress of the second domestic aircraft carrier.
