"Is it okay to start the foam mix next?"

Mu Tianyu handed over to the engineer and Wang Xu, and immediately began to direct the leakage cut-off operation.

When the red giant fire truck roared like an angry roar, Mu Tianyu felt the hope of success.

Wang Xu shouted excitedly: "Master, this is called passion and speed!" ”

Mu Tianyu suddenly remembered and asked him why he was here?

Before the fire, he was still racing his supercar car. felt that it was too long to talk, so he changed his words and said: "Since you have arrived at the fire rescue scene, pay attention to safety." ”

Mu Tianyu felt that he had followed him to the fire, so he must be playing for real. But being able to race a car does not mean that you can fight fires. I don't know if he has trained, the fire is like a battlefield, and safety is of course the first priority.

This Wang Xu, who is usually very unassuming, was taken care of by the "master" for the first time when he went on a mission with Mu Tianyu, and his heart was quite warm, a little excited, but he didn't know how to answer, but he just nodded.

At this time, the aerosol bubbles began to spray, and a very spectacular scene appeared in front of everyone's eyes at once.

In just a few seconds, the entire sky seemed to be covered in misty bubbles.

Soon the mist contracted and enveloped.

All the flames were suffocated and isolated.

The smoke began to dissipate, and the temperature of the space began to drop.

Everything is magically good!

Mu Tianyu said: "When I go back, I have to study the turbojet fire truck." ”

Maybe Mu Tianyu said it to himself, maybe he wanted to plan a new training subject in the Jiangcheng Fire Detachment......

Wang Xu immediately replied, "Yes, master." ”

Hu Haoran also replied: "Yes." ”

Liu Lei even said: "The vortex technology has finally succeeded. ”

The turbojet fire truck is to use the aviation gas turbine engine as the power to spray the fire extinguishing agent, which is installed on the chassis of the car and equipped with the water tank, foam fire extinguishing agent tank and water pump of the conventional fire truck.

The turbojet engine on the turbojet engine used by Mu Tianyu can produce a jet power of 5,000 kilowatts, which uses a high-speed gas jet as the carrier to make a direct flow of 100 liters per second collide with a high-speed gas jet in the accelerator, producing a large flow of "gas-water mist" jet (or "gas-foam-ultra-fine dry powder fire extinguishing agent" jet), realizing the long-distance and high-intensity injection of large specific surface area fire extinguishing agent.

The effective spraying distance can reach 150 meters, which can cover a fire area of 500 square meters in an instant, which is 15 to 20 times higher than the fire extinguishing capacity of conventional fire trucks, and the power-to-mass ratio is greater than 150 kW/ton.

Although, the turbojet fire truck is the world's fire truck with the largest jet power spraying water mist or composite fire extinguishing agent with high-speed driving ability, and has exerted great fire extinguishing power in airport and oil field firefighting.

But in this fire fighting battle, some problems were also found, which were to be solved by Mu Tianyu and his fire experts.

In fact, it has been a long time since the appearance of vortex fire trucks. At the earliest, the turbojet fire engine was put on the Gas-51 car by the former Soviet Union to test fire extinguishing; Later, similar experiments were conducted in Texas, USA.

The real sensation was the oil well fire in Kuwait.

In 1991, after the end of the Gulf War, 27 firefighting teams from 10 countries worked together to extinguish fires in 727 oil wells in Kuwait.

Among them, the Hungarians installed two Я-11Φ-300 aviation turbojet engines, that is, the WP-7 engines on the MiG-21 fighters, on the T-34 tanks side by side, and used the high-speed air flow generated by the turbojet engine with a jet power greater than 10,000 kilowatts to cut the seawater injected into the air flow into a mist of water and spray it into the oil well fire, and successively used 12 seconds to 120 seconds to extinguish several oil well fires, which opened the eyes of 26 fire brigades from 10 countries participating in the fire fighting battle.

The extinguishing of oil wells in Kuwait has demonstrated the great power of vortex fire trucks, so there has been an upsurge in the development of vortex fire trucks at home and abroad.

Since the turbojet fire trucks are used, most of them are retired aviation gas turbine engines for the army. Therefore, the advantages of low price and controllable cost have laid a material foundation for the development and application of turbojet trucks. As a result, a series of new equipment such as turbojet snowplows, turbojet decontamination vehicles, and turbojet anti-riot vehicles have been derived.

There are three types of turbo spray fire trucks: jet type, water spray type, and ultra-fine water mist jet type.

The so-called jet type refers to the turbojet engine is simply fixed on the carrier (such as a car, tank, etc.), and the exhaust gas of the turbine engine is used to blow out the fire. In a sense, the jet is the original turbojet fire truck.

The so-called water spray type is to send water into the air flow outside the nozzle of the jet engine, and directly impact it by the water and air jet under unconstrained conditions in the atmosphere, exchange kinetic energy in the impact, and form a larger particle size water mist to extinguish the fire by the impact of the air flow.

The so-called ultra-fine water mist jet type is designed to design the kinetic energy exchange device of water and high-speed gas jet, so that the energy of gas and water jet can be fully exchanged, the particle size of water mist is smaller, and the diffusion angle of the jet is smaller, so as to obtain a longer jet distance.

From Mu Tianyu's actual combat, it can be seen that there are still several problems to be solved in the vortex spray fire truck.

The first is the issue of the start of aviation gas turbine engines.

At military airfields, which themselves are users of aviation gas turbine engines, have a complete set of logistical support equipment and technicians. However, when equipped with a local fire brigade out of airport conditions, the very cumbersome batteries required for start-up cannot be maintained and used for a long time; Firefighters are difficult to master when mechanics and pilots work together to get an aircraft engine in motion.

The second is the cost of extinguishing fires.

Aircraft engines burn special aviation oil, which is very expensive, and is used as a fire truck to extinguish fires, which is very large and costly; In addition, jet fuel is a special fuel, and it is difficult for fire brigades to ensure the supply of this fuel.

Thirdly, most of the fire brigade personnel have not been exposed to aircraft engines, and they are intimidated by the turbojet fire trucks, feeling that they are highly technological, and they are worried that they will break down and cause damage to the facilities.

At present, diesel fuel is used to replace aviation gasoline as the fuel for turbojet engines to solve the problem of supply difficulties and high use costs, but the power will be relatively reduced; Secondly, the system device for starting the aero engine with a hydraulic motor was developed, which changed the cumbersome and easy to fail operation program, so that the start of the aero engine was as simple as the car driver starting the car, but it was not very mature, and it was also a compromise under relatively low power.

Mu Tianyu looked at the performance on the scene, and thought that it was the key to this technology because of the effect brought by the extreme play of the high power of this turbojet technology.

"Start Operation Cut-Off Valve Now!" Mu Tianyu issued a new order in time.
