Chapter 429: Why are your ghosts and mine different (page 1)

While Chang Haonan was busy working on the Air Police 200 and Turbofan 10 projects.

Tehran, Mehrabad International Airport.

An Il-76TD transport aircraft painted in a Soviet civil aviation livery that is quite strange for this era is preparing to land in a quite classic "maximum slope landing" attitude.

This method requires the pilot to align the aircraft with the runway in a dive attitude and level the aircraft at the last moment before touchdown.

A great test of courage and skill.

A few minutes later, the IL-76 stopped smoothly at the end of the runway. There were already many people and two trucks there, obviously waiting for a long time.

Yang Jin, an engineer from Factory 112, walked forward quickly with the staff behind him, preparing to unload the goods.

The huge three-flap tail hatch slowly opened.

The scene inside the cargo hold shocked Yang Jin, who saw the Il-76 for the first time.

There are six turbojet 14 engines flown from Shengjing.

Although the turbojet 14 is an engine with a small size and weight, in order to ensure a foolproof transportation process, the 410 factory often uses very exaggerated boxes for packaging before installation.

The first batch of four engines were all transported by Y-4. Only two engines could be transported at a time, and the cargo hold capacity was still tight.

Several people jumped down from the huge springboard door. The leader came to Yang Jin, shook hands with him, and then said in a slightly anxious tone:

"This is the second batch of six engines. Move quickly. There will be another plane coming later."

"Six more engines?"

Yang Jin was a little unbelievable.

As a technician at Factory 112, he is still aware of the capabilities of Factory 410, a sister unit.

Only 4 units were delivered in total in the past six months.

After all, the turbojet 14 model is used everywhere, and it is impossible to give it all to them.

"No, there are some other aviation materials behind it, as well as radar."

It wasn't until everyone started unloading the cargo with the help of the tail crane that the other party breathed a sigh of relief and introduced himself:

"Comrade Yang Jin, right? My name is Han Linping. I'm from Factory 410. I'm responsible for cooperating with Persia's ghost modification project."

"Hello, but it wasn't always Lin the past few times..."

"Lao Lin was transferred to be responsible for the logistics support of key model projects, so I came to replace him."

Han Linping explained.

Yang Jin was stunned after hearing this. He had followed the overseas working team established by the factory to Persia six months ago and had not returned to China since then, so he had very little information about this aspect.

However, he also knew that this was definitely not a place to discuss confidential topics, so he had no choice but to suppress his curiosity:

"That's a pleasure to work with."

"Pleasant to work with."

As Han Linping said, about twenty minutes later, another Il-76TD with the same painting landed in the same wild way, bringing other parts involved in the improvement project.

"You rented these IL-76s specifically from Lao Maozi?"

After unloading all the aviation materials and loading them into the truck, a somewhat out of breath Yang Jin found Han Linping.

These two huge aircraft really left a very deep impression on him.

"No, I bought a few finished aircraft from the Tashkent factory a few months ago. I didn't have time to change the paint. The superiors considered that this could be a bit confusing, so they used them like this for the time being."

Han Linping, who had just taken off his gloves, shook his head and looked at the IL-76 who was preparing in the distance and explained.

At just this moment, a Land Rover off-road vehicle stopped in front of the two of them.

"Get in the car first"

Yang Jin opened the car door and motioned for the other person to sit in.

In fact, as a dual-use airport with a large passenger flow, Mehrabad International Airport is not suitable for undertaking such sensitive military transportation tasks.

Even the Persians themselves know this and are therefore planning a new Imam Khomeini International Airport.

However, construction has just started and is far from being completed.

The reason why I have to use this place is because the only Persian Aircraft Industry Company (IACI) that has the technical ability to maintain F4 and F14 fighter jets is right here.

It even shares one of the runways with Mehrabad International Airport.

If it lands somewhere else and is transported by truck, not only will it cause more noise, but there will also be other risks along the way.

In the end, we can only choose to carry out transportation tasks in the evening or early morning when there is less passenger flow.

Fortunately, after switching from Y-8 to Il-76, the number of flights required will be much less.

"How is our current modification progress?"

After watching the rapidly regressing scenery outside the window for a while, Han Linping quickly felt a bit monotonous, so he turned back and asked about the project.

"The first two upgraded aircraft have been delivered, and now we are just waiting for your engines to start work."

Speaking of this, Yang Jin couldn't help but smile:

"Seriously, you should have come here a month earlier to listen to how the Persians praised the two new engines we installed..."

While the two were talking, an F4 fighter jet painted in blue and gray roared and took off from another runway not far away.

"Well, that's one of the ones we modified. The Persians renamed it F4EC and also changed the paint."

……

Lieutenant Colonel Siavash Bayani and Captain Sania Hoda were sitting in the cabin of the F4 that had just taken off, flying towards the northwest.

Radar stations there reported several unusual approaches by the Turkish air force.

Since the Persian Air Force has been troubled by the problem of aircraft readiness rate since the Iran-Iraq War, under normal circumstances, it will not respond to such actions by neighboring countries.

Moreover, Tehran is more than 400 kilometers away from the border between the two countries, so most of the time it is simply too late.

But one of the opponent's targets seems to be particularly persistent today, wandering near the West Azerbaijan Province several times and showing the intention to cross the border many times.

Then you have to go and see it.

After quickly climbing to the predetermined altitude of 12000 meters, Lieutenant Colonel Bayani pushed the throttle valve to the end and opened the afterburner.

The number on the aircraft's airspeed indicator increased rapidly and soon exceeded the speed of sound.

作为曾经击落过幻影F1、苏20和米格25的王牌，现年40岁的巴亚尼几乎是整个波斯空军中驾驶F4经验最丰富的飞行员。

But after being transferred to TFB1 base and equipped with this new aircraft, he even began to doubt his nearly two thousand hours of flying experience.

Although the sea-level thrust of the turbojet 14 is about 79% lower than that of the J7, its dry weight is almost only 60% of the latter. As a result, the thrust-to-weight ratio of the entire aircraft has even increased after thrust reduction and trimming.

But this is not a big problem. What makes him uncomfortable the most is actually the difference in feel caused by the increase in power feedback speed.

In the past, the F4 would have a very slow speed increase process after the throttle valve was activated. As a result, Bayani, who had already formed a habit, felt like he was acting like an old man in the first ten hours after boarding the plane. dementia.
