Among the people who were with Hikmat, because they were mainly here to negotiate the proactive Sky Flash Project, in addition to the negotiation experts, there were only the Air Force missile technicians related to this plan, and there were very few people from the Army and Navy. However, Hikmat still felt that this was an opportunity!

What is Iraq’s most lacking? It’s not funds, but things that can be bought, especially the production line. He seems to regret it now. If Iraq has cooperated with Sweden from the beginning, then many projects are probably going to bear fruit now. Americans always like to put pigeons, British people hug American thighs tightly, and they always dig holes for Iraq. The French are very enthusiastic, but if they want to start the price, it is absolutely ruthless. The Soviet weapon, Kusai looks down on electronic equipment, and Sweden just fills these gaps.

Even if the people of the whole country have tied up their belts, they will introduce the projects that should be introduced. Of course, this is just a saying. Iraq is backed by two moguls of Saudi Arabia and Kuwait, and has crude oil from Khuzestan Province. Iraq's economy has developed greatly. Moreover, Iraq has been developing military industry, and it is not entirely only investment. Iraq will still be a major weapon exporter.

While reporting to the country, Hikmat also extended his itinerary in Sweden. He needed to go to more places to check out, collect more things needed by Iraq, report to His Excellency Kusai, and then make decisions on the projects he decided to introduce.

"You are by far the country that attaches the most importance to air force equipment. Now, you are using hunting early warning aircraft imported from the UK. This early warning aircraft has played a significant role in your air combat. However, this early warning aircraft is just the result of the expansion of ordinary airborne radars and has various disadvantages. Therefore, you need early warning aircraft with more advanced technology." Scheller, who was accompanying Hikmat, said.

If the visitor was Kusai himself, then it would be possible to guess that the Swedes were going to promote their efforts on the early warning aircraft to Iraq, which is commonly known as the balance beam in later generations, and the current Ericsson Eye Warning System.

Early warning aircraft, such a multiplier of air combat power, has attracted more and more attention from countries. However, to now, there are only a handful of countries that can develop early warning aircraft, with the most powerful Americans, the most mature technology, and the Soviet Union, which has also developed to the second generation, the Air Police One of the Eastern power, but ended in vain. The British hunting fan early warning aircraft was finally taken over by Iraq and blossomed in a foreign country.

Sweden needs national conditions and also desires early warning aircraft. However, Sweden is a small country, and it is obviously not suitable to take the path of the United States and the Soviet Union. Sweden needs a small early warning system with high cost performance.

Since the early 1980s, Ericsson Microwave Systems has started developing airborne early warning radar systems, and directly skipped the early stages of the development of national early warning aircraft such as the United States and the Soviet Union, such as traditional airborne surveillance radars and even passive phased array radars, and directly started from airborne active phased array radars.

Ordinary radars scan the surroundings through the rotation of the antenna, while phased array radar uses a "phase shifter" to realize the radar beam rotation. When the antenna is still, it is called electric scanning. Passive phased array radar has only one central transmitter and one receiver. The high-frequency energy generated by the transmitter is automatically distributed to each radiator of the antenna array by a computer. The target reflected signal is amplified uniformly by the receiver. Each radiator of the active phased array radar is equipped with a transmit/receive component, and each component can generate itself and receive electromagnetic waves. Therefore, in terms of bandwidth, signal processing and redundancy design, it has a greater advantage over passive phased array radar. This individual component is an insurmountable gap in front of all radar experts. In this regard, the United States is not advanced enough.

Ericsson is one of the world-famous electronic companies. It has invested a lot of energy in this area. By now, it has made breakthroughs in major technologies. The FSR-890 "Ericsson Eye" airborne active phased array early warning radar is about to emerge.

In later generations, this airborne active phased array early warning radar was successfully conducted in aerial tests at the end of 1985. At the Paris Air Show in 1986, the ps-890 Ericsson Eye radar was publicly unveiled for the first time. The Swedish Air Force used the US Metro transport aircraft as a platform to modify the Metro-3 air early warning aircraft. This was the first early warning aircraft in Swedish history. Later, the Saber 340 transport aircraft was selected as the body and converted into a Hundred-Eye Giant early warning aircraft.

A small country in Sweden can achieve great achievements in all aspects, which has a lot to do with their defense industry model. Their neutral foreign policy allows them to absorb various foreign investments. As long as they are not like the bearded man, they can interact with Sweden. Now, rich countries from the Middle East and are very brave to try new technologies. Sweden has put forward its own early warning system, hoping to win investment from Iraq. Iraq can spend so much money to purchase British hunting early warning aircraft and invest in the active sky flash missile that Sweden has not yet developed. So, this active phased array radar is probably more interested. At present, attracting Iraq's funds can allow this early warning system to enter the practical stage earlier. The cooperation between the two sides is win-win, and Scheller is very sure to win the favor of Iraq.

"Is that true? You also have an early warning aircraft project?" Hickmat said with interest. At this time, he had not recovered from the project he had just inspected.

"Yes, our early warning aircraft is more advanced than the United States and the Soviet early warning aircraft. The early warning technology we use is the active phased array radar, which is a new type of radar. The United States has not made any breakthroughs yet," said Scheller. "If you are interested, our next inspection site will be our Ericsson."

"Yes, we're very interested," said Hickmatt.

For a look, you can take some introductions of these projects before leaving so that you can take them back to report to You Kusai. If You Kusai is very interested, you will not be empty-handed. However, Sweden obviously misunderstood and thought Iraq would invest in these projects, which would be better. They would spare no effort to introduce the specific performance of these weapons and equipment to Iraq, such as the specific performance of these weapons and equipment.

Hickmatt is an amateur, which does not mean that his accompanying team is all amateur. When they hear the active phased array radar, they are moved. The project they just inspected excited the only naval representative. This naval representative is Mustafa, the captain of Iraq's Tr-1700 submarine.

The project I just saw is called the Stirling AIP system!

Since the birth of the submarine, it has become a killer hidden under the water, lurking under the dark water, relying on its own sonar to monitor everything on the sea surface, using torpedoes to launch its own attack, and becoming a killer at the seabed.

However, this killer has a fatal weakness. Underwater, he can only rely on batteries to provide power. Because the energy provided by the battery is limited, even if it is sailing at a low speed, it can only last for a few days. If it is sailing at a high speed, it will consume all the electricity for one or two hours.

Therefore, conventional submarines need to float up to at least the depth of the snorkel at every certain time, let the diesel engine they carry ignite and charge the battery. At this time, the submarine is the most dangerous time. In the war, the captain mustered up the courage to take considerable risks to float up and charge.

Except for nuclear submarines, nuclear submarines can sail underwater with their almost unlimited power. However, not any country can equip nuclear submarines. First of all, nuclear submarines are not taken out. All countries make their own products. Secondly, even if they can be purchased, the high price and maintenance costs are not affordable by ordinary countries.

Therefore, most countries use conventional submarines.

Sweden cannot equip nuclear submarines, so they took their own unique path and studied an underwater auxiliary power system, namely the Stirling AIP system, which is a unique closed-cycle hybrid system, mainly composed of two V4-275r Stirling engines, several low-temperature liquid oxygen cabinets and their control equipment. The Stirling engine is a V-type 4-cylinder external combustion engine, with the main components of the heater, pressurized combustion chamber, ring-type heater, cooler and cylinder block. During work, oxygen from the liquid oxygen tank and fuel tank are injected into the pressurized combustion chamber respectively, and ignite and burn through the hotline ignition plug. The starter motor drives the crankshaft to rotate and perform work, thus establishing a working cycle and providing continuous power for the submarine with a total power of 150 kilowatts. The Stirling AIP system operates smoothly, has low vibration, is safe and reliable, has a high thermal efficiency, low exhaust pollution, low failure rate, and has a long service life.

In addition to supplying the 75 kW of power to normal lighting on the boat, electronic equipment work and living facilities, the remaining 75 kW of energy can be used to propel the submarine, so that the submarine with a displacement of about 1,500 tons can obtain an underwater speed of about 6 knots, and can maintain the speed continuously for 15 days.

To put it simply, this system is an external combustion engine that is equipped with liquid oxygen and fuel, so that it can perform work underwater, thereby obtaining continuous power until the fuel and combustion aid are exhausted.

When he heard these data, Mustafa's eyes shone. He had made up his mind to report to His Excellency Kusai after he went back, hoping to equip this system. Because this system can not only be used on new submarines, but also be modified on old submarines. However, what the Swedes said in the end was that this system is still in the final development stage. If Iraq is willing to join this program, it will be installed on the submarine for trial at the latest next year.
