Of course, no matter how good the performance is on the ground, it is useless, since it is an airplane after all, it still has to fly to see the actual effect, and the test pilots who carried out the test flight and sent by the HNA unit are also very aware of this, and after completing the folding of the wings and rotors, they immediately put the rotors and wings into the flight state, and the engine began to warm up.

Taking advantage of the fact that the plane had not yet taken off, Chief Engineer Guo seized the time to introduce the situation and characteristics of the Zhi-9X to the generals of the Navy, "This Zhi-9X is still using the turboshaft-8A turboshaft engine on the Zhi-9, and we have not made any adjustments to the power system, but in order to ensure that the vector thrust ducted propeller can get enough power, we have made some adjustments to the final reducer, and under the premise that the power has not increased and the weight of the aircraft has increased by more than 700 kilograms, the straight-way that has taken off by taxiing and taking off has been adopted. The maximum load of the 9X can reach 3.5 tons. ”

"Wouldn't it? 3.5 tons?! ”

This time, not only Major General Zheng, but even General Wang Xu also exclaimed.

You know, the maximum load of the Z-9 is only 2 tons, the Z-9X is not only the addition of a pair of heavy wings and vector thrust duct propeller structure, together with the enhanced fuselage structure, the weight of the aircraft has increased by more than 700 kg, but in this case, the maximum load of the Z-9X has not only not decreased, but also increased by 1.5 tons?!

This is not only against the sky!

It's just against the sky!

When the other generals were still immersed in shock, General Wang Xu was the first to react, couldn't wait to grab Guo Jingshan's hand, and eagerly asked Guo Jingshan, "Chief Guo, what is the running distance of the straight-9X full take-off?" ”

That's right, what is the take-off distance of the straight-9X with a full load of 3.5 tons?

Hearing this question from the commander, everyone was stunned. Then I realized the importance of this problem: the Z-9X is a technical reserve for the future carrier-based early warning aircraft, and this full-load sliding distance is very important!

"The result of our test was 210 meters under pure ground and no wind, but when we simulated that there was no wind on the sea surface and the aircraft carrier was sailing at a speed of 28 knots, the take-off distance of the Z-9X with a full load was only 148 meters."

Guo Jingshan's tone was full of pride, and obviously, he was full of pride in this number.

"158 meters? God! ”

Hearing Guo Jingshan's words, even these admirals who have seen a lot of wind and rain can't be calm.

As admirals, the generals are good at math...... It has to be good, too...... A simple conversion immediately realizes the fork of this data: the speed at sea is 28 knots, which is 51.86 kilometers per hour. Even in windless conditions, the relative wind speed reached 14.4 meters per second.

But in fact, there will be no wind on the sea, most of the time there will be wind on the sea, and aircraft carriers, especially aircraft carriers that do not have steam catapults and can only choose to take off by glide jump, will not only use the maximum speed when flying. At the same time, the aircraft will take off with a headwind attitude.

The purpose of this is to increase the speed at which the air flows across the wing surface of the aircraft and to minimize the distance the aircraft can take off. In fact. This is true not only for aircraft carriers with glide jumps. The same is true for aircraft carriers that adopt catapult take-off.

The sea surface wind speed is 28 knots, and the take-off distance without wind is only 148 meters, not to mention a large aircraft carrier like the "Varyag", even if it takes off on an ultra-light aircraft carrier with a full load displacement of only one or two hundred thousand tons such as the British Invincible class and the Spanish Prince of Asturias, the deck length is sufficient.

"This is the worst-case scenario, in fact it is extremely difficult to come by, and we have simulated a situation where the aircraft carrier takes off against the wind when there is only a force 4 wind on the sea...... Category 4 winds can only be regarded as small winds at sea...... The relative wind speed at this time is about 20 meters per second. With a take-off distance of about 110 meters, the Z-9X has no problems taking off from the deck of any aircraft carrier. ”

"We have simulated and calculated some situations in the future of the Z-13X based on the existing preliminary design data of the Z-13X, and the take-off distance of the Z-13X with full load will not exceed 200 meters," Guo Jingshan said. Finally, I couldn't help but say, "Counting the low-speed heavy ground attack aircraft we are developing, on the premise of having the Z-9X and Z-13X, we can also develop a type of amphibious helicopter attack carrier similar to the American Wasp class with a large through-deck, this kind of warship should still be widely used in the South China Sea, and it also has enough power and attack power to deter Xiaoxiao." ”

Development of an amphibious military helicopter carrier similar to the American Wasp-class amphibious assault ship? Hearing Guo Jingshan say this, the generals' eyes suddenly lit up!

Yes, under the premise that we cannot develop aircraft carriers in the short term, we may be able to safeguard our country's interests in the South China Sea region and ensure our country's military presence and deterrence in the South China Sea through the development of this amphibious assault ship. Enough is enough!

It doesn't have to be like the Americans' Wasp-class amphibious assault ships with a displacement of 40,000 or 50,000 tons, just like the "multifunctional amphibious assault ship" that the French just started this year...... Well, this cargo is the later French Mistral-class amphibious assault ship.

With a full load displacement of more than 20,000 tons, it has strong amphibious combat performance, and it can also be pretended to be an aircraft carrier when necessary...... Now it's a helicopter carrier, and in the future, maybe we'll be able to develop a jet short-takeoff fighter, and then this cargo will be transformed into a light aircraft carrier.

Well, maybe at the very beginning it can be made into a light amphibious assault aircraft carrier with a sliding deck?

Several generals exchanged glances with each other, and there was some excitement in their eyes: It seems that you can operate it? …… It's really a shame, if it weren't for Comrade Guo Jingshan's reminder, we really wouldn't have realized this.

Seeing that a group of generals were distracted, and glanced at the Zhi-9X that had begun to glide in the distance, Lin Hongfei reminded the generals with a smile, "Everyone, the plane has begun to take off......

Well? Ready to take off?

Everyone hurriedly looked at the runway, and the next moment, under the gaze of everyone, the culvert of the tail vector thrust duct propeller of the straight-9X with a small forward-swept folding wing was obviously deflected downward, and the straight-9X, which was fully loaded with simulated load, crossed a short distance on the ground, because of the wind at the test site today, the take-off distance did not even exceed 150 meters, and the strange-looking straight-9X quickly took off under the double lift provided by the rotor and wing!

"Beautiful!" The generals applauded!

"There's even prettier." Lin Hongfei smiled mysteriously.

"And prettier?" The generals blinked, and suddenly became excited: could it be that the preparation of the carrier-based AWACS / air tanker platform has already made a prototype?

……………………

The platform of the carrier-based early warning aircraft / air tanker has not been made now, with the development of electronic computer technology, paperless design has been realized, unless it is for propaganda, there is no need to make large-scale models, but this big guy in front of him still brought great horror to the generals of the Navy.

When they saw the big guy in front of them, several generals were stunned for a moment, their faces showed disbelief, and their faces were inexplicably shocked, "This is ...... Black Hawk?! ”

Yes, the helicopter parked in front of him is exactly the same as the Black Hawk helicopter introduced from the United States during the Sino-US honeymoon, but the generals all know that the plane in front of them is absolutely impossible to be the "Black Hawk", and the civilian version of the Black Hawk helicopter of the Republic has always been supplied as a treasure, and the Navy and Bingfei will never have a chance to get these treasures. Case......

The general looked at Lin Hongfei in unison, "Mr. Lin, this Black Hawk helicopter is ......"

"This is our imitation," Lin Hongfei pointed to the "Black Hawk" in front of him and said to several generals, "Everyone knows that we once imitated the Black Hawk helicopter back then, but it ended up stuck in the engine, but in addition to the engine, in fact, we have completed the imitation of other systems and sub-modules of the 'Black Hawk' helicopter." ”

General Wang Xu and the others nodded again and again. After spending a lot of money to introduce the civilian version of the Black Hawk, in view of the excellent performance and reliability of the "Black Hawk" helicopter, the state immediately organized relevant enterprises and experts in the military industry to secretly carry out imitation work on the Black Hawk helicopter, and the entire reverse imitation and mapping project was completed about 70%, and finally because our materials and finishing capabilities were not up to par, we were stuck in the engine.

The electronic system of the civilian version of the Black Hawk helicopter introduced at the beginning is not complicated, and there are no major problems encountered in the imitation of the electronic system, even if some cannot be imitated, we can make up for it in other ways.

"So you've solved the engine problem?" General Wang Xu asked eagerly.

The Navy has been coveting the "Black Hawk" for a long time, but there are only a few in China, and the Navy has no idea at all, but if we can produce the Black Hawk domestically, the Navy will have a better platform for anti-submarine operations. As soon as he thought of this, General Wang Xu's face flushed a little.

"That's right."

"Huh?"

"The RTM322-9 turboshaft engine secretly imported by our company from rolls-Royce, the RTM332-9 is the same level of engine as the F700 used on the 'Black Hawk' and 'Apache', and the 'Black Hawk' helicopter used by the British themselves uses the RTM322 engine...... After solving the last stumbling block of the engine, there will be no obstacle to the localization of the Black Eagle. (To be continued......)
