At that time, the four European countries urgently needed a fighter that could not only meet their own air defense tasks, but also cooperate with other European NATO countries. Participating in the competition were the French Mirage F1 and the American F16.

In the end, due to the technological gap, political pressure and military needs, the four European countries unanimously chose the American F16 fighter as their "joint fighter".

The French are very angry.

This fighter is taken out to the Chinese, can they be satisfied?

So what we are preparing today are two plans, first use the Phantom F1 to fool them!

Thinking of this, Boileau smiled.

"Ladies and gentlemen, you have just arrived today, and you may be very tired, so I will give you a projection display today." As he spoke, Boileau pressed the button, and the curtains slowly lowered all around, and the entire conference room went dark.

The slide projector was turned on, and the screen was lit up.

The aviation industry in the West is advanced, and Dassault is a world-famous fighter R & D manufacturer, which has produced many of the world's most famous fighters.

It's a pity, if I stayed for a while longer, maybe I would have had a chance to fly the Phantom.

"This is the main product that Dassault sells to the outside world, the Mirage F1 fighter." Boileau said that he used very clever words, this aircraft is the main force of external sales, and the Mirage 2000 is the latest, but after all, it has not been sold yet, and even all the test flight projects have not been completed.

Looking at the slides, Qin Feng suddenly wondered for a while, the Phantom F1 was actually a failed attempt by Dassault, why did he introduce this aircraft to everyone?

Why failed?

Dassault's best thing is the tailless delta wing layout!

Aircraft of other design bureaus, with wings, have a tail, which is a conventional aerodynamic layout, and it is also one of the most common ways for aircraft of various countries.

Dassault's main fighters are all without tails, a large delta wing, starting from both sides of the front of the fuselage and running through to the end, which is called a tailless delta wing.

The United States has the most developed fighter development, and it has always been a conventional layout, and has never engaged in anything else.

Dassault only works on delta wings without tails, but this Mirage F1 is a special case, which uses a conventional aerodynamic layout.

And once this special case is over, the current Phantom 2000 has become a tailless delta wing layout, which is enough to explain the problem, this is not just Qin Feng's speculation, many professional magazines have already compared.

"Our overall structure is a conventional swept wing layout, with a leading edge maneuvering flap and a trailing edge double flap installed on the wing. The horizontal rear wing is a low-mounted, full-motion type. Two pelvic fins were added to increase lateral stability, while the leading edge of the wing became serrate. ”

The development of science and technology in the West, it can be seen from a small leading edge maneuvering flap, this device is not complicated, that is, the leading edge of the wing can move downward, and when it turns downward, it can greatly increase the lift.

But just such a gadget, it can't be done in China, because the hydraulic cylinders that operate it require high-precision processing, and the domestic process can't reach it.

It was not until the late eighties that the leading edge mobile flap was used on the J-7 in China, but because of the lack of processing accuracy, there were often problems.

"Our power plant uses a single Seta 9K-50 turbojet engine from Snekma with an afterburner thrust of 70.6 kN. The total fuel volume in the aircraft is 4300 liters, with two 1130 liter auxiliary fuel tanks on the inner pylon of the wing, and a 2200 liter auxiliary fuel tank can be hung at the lower hanging point of the fuselage in order to perform long-distance interception missions. ”

Although it is a turbojet engine, it is full of power, and if this engine is installed on the J-7, the maneuverability will definitely go to a higher level.

Still, think about it.

The slide was put on the third sheet, which was already mainly about the electronic equipment of the fighter.

"The nose of this aircraft is equipped with the Thomson-CSF Silas IV fire control radar. It has multiple modes of air-to-air and ground, and belongs to a single-pulse system, which can be used to control the R530 missile. ”

When they heard about the fire control system, everyone was interested, as air force personnel, everyone deeply knew that the technical level of domestic military aircraft is very low, and there is a gap of at least ten years with foreign countries, and the gap in airborne electronic equipment is even greater, after all, over the years, the West has developed too fast.

When the West has widely used pulse Doppler radar, it still has a headache on a small single-pulse radar, what drops high voltage, what tracking is unstable, and these failures have not stopped for a day.

Qin Feng listened very seriously.

The R530 missile is France's own so-called medium-range air-to-air missile, which is called a medium-range air-to-air missile, in fact, there is a feeling of slapping a swollen face and being fat, after all, its range is only about 20 kilometers, and it can be seen by the naked eye, and it is a missile within complete visual range.

Even if it is developed to the Super 530 missile, the maximum range is only 30 kilometers.

Compared with sparrows, it is naturally a weak chicken, but if it is compared with the current level in China, it is also advanced. Think about the domestic Thunderbolt-4, I don't know when it will be able to have eyebrows.

Its electronics also include two HF radio communication stations, the Socrat 6200 VHF omnidirectional beacon/instrument landing system, the telephone equipment company's Takan, and the NR-AI-4-A friend-foe transponder. Ullis 47 inertial navigation system, EMD182 central digital computer for navigation / attack, 505 autopilot from Air Navigation Equipment France, air data computer and digital weapon control/navigation control selection board from Kreuzer company, THC8FVE-120C cathode ray tube head-up display, etc. Boileau pointed to the slides and explained them in detail.

This is the technical level of France in the early seventies, and it is definitely a notch higher than the avionics level of its own state-of-the-art J-8.

When Qin Feng saw these avionics, he couldn't help but secretly think in his heart, if it could be introduced and installed on the J-8 fighter, how good it would be.

Not to mention anything else, the inertial navigation system is the best kind of navigation equipment for fighters when they fly long distances, and there is no fighter equipment in China, everyone is familiar with the landmarks, flying in the airspace they are familiar with, and it is easy to get lost in another place.

Qin Feng didn't speak, he listened quietly, and when the other party finished broadcasting the last slide, the lights in the room turned on again.

"If you have any questions, you can ask them." Boileau said with a smile.

General Lin gestured to Qin Feng, so Qin Feng no longer hesitated.

"Mr. Boileau, we heard that you introduced the Mirage F1 fighter jet very well, can we learn more about some of the electronic equipment on this aircraft? Also, did such an aircraft achieve hot-wire aiming of the cannon? ”
