Chapter 856： new supersonic reconnaissance aircraft

? What plane needs to be faster? Certainly not a fighter! A fighter jet needs to integrate the technical conditions of all aspects. If it only works on speed, it will inevitably lead to a reduction in other technical indicators. The MiG-25 is an example. Although it flies very fast, its body is not. It is extremely bulky. For ordinary pilots, it is definitely not as good as the small and flexible MiG 21 to use it for fighting.

However, another type of aircraft requires the higher the speed, the better. This is the reconnaissance aircraft!

Although with the continuous development of reconnaissance satellites in space, there is a tendency to replace reconnaissance aircraft, but in some respects, reconnaissance aircraft are still very useful. For example, satellite orbits are fixed, and a lot of fuel is consumed when changing orbits. At the same time, it is impossible for satellites to quickly pass over the target at the same time. If you want to conduct more detailed reconnaissance of the target, the reconnaissance aircraft is still very useful.

For example, if the satellite finds the launch vehicle of a ballistic missile in the target area, then the reconnaissance plane can quickly carry out a reconnaissance, precise positioning and fast response.

For reconnaissance aircraft, of course, the higher the flight, the faster the better, which means that it will not be threatened by the opponent's air defense system!

At the beginning, after the MiG-25 was finalized, it immediately developed a reconnaissance type. This aircraft dominated the sky and was invincible. It could invade the airspace of any country at will, and then reconnaissance. Even if you encounter the opponent's anti-aircraft missiles, you can use the speed magic weapon to avoid the missiles.

Now, the MiG-25 is out of date, but the Soviets still need newer strategic reconnaissance aircraft!

Andrei and Ustinov, seeing the headmaster Sergei Nikolaevich Anokhin hurriedly approaching, in the more secret area behind the Gromov test flight complex, were right The arrival of the two people, Sergey expressed a very welcome.

"Sorry, there are some problems with our test flight, and the technicians are dealing with it." Sergey said: "Comrade Marshal, Comrade General, are you here to see our Tu-260 reconnaissance aircraft?"

Tu-260? Hearing this number, Andre felt a burst of excitement in his heart. In the decrypted materials of later generations, these projects seem to be projects on paper. Now, there are already prototypes?

As a test pilot, the later Andrei was interested in many Soviet declassified materials, including this high-speed strategic reconnaissance aircraft.

The size of this kind of aircraft is very large, almost the same size as the Tu-144, which is the supersonic passenger aircraft of the Soviet Union. .

This is a large aircraft, with a maximum take-off weight of 180 tons, far exceeding the size of an ordinary reconnaissance aircraft. At the same time, the aerodynamic shape of this aircraft is somewhat the same as that of the Tu-144, and there are also differences. The main reason is that the nose has no moving parts and will not sag. At the same time, it has been replaced with a larger engine.

After all, the prototype Tu-144 has a good supersonic capability. In operation, it has been flying at Mach 2 for a long time, showing the huge potential of this aircraft.

And it is really a creative idea to change this supersonic passenger plane into a supersonic reconnaissance plane.

"Yes." Ustinov said, "How did the test flight of this aircraft go?"

"The test flight has met our expectations. However, this aircraft is not suitable for mass production, and it cannot deal with future threats." Sergey said, taking everyone to a hangar next to him. On the side, there is a big plane lying quietly!

The shape is slender, the engine is placed under the rear of the fuselage, and the rear with a high aspect ratio has a slightly double-****** tailless design, all of which are prepared for supersonic flight.

The case is shiny, it's a titanium alloy material!

Regarding the materials used for supersonic fighters, the United States used titanium alloy to create sr-71, while the Soviet Union used stainless steel to create MiG-25sr-71, which was extremely delicate and widely criticized in use, while the Soviet MiG-25 was a Seen as a model for the correct choice of materials.

However, that was in the 1960s. At that time, the United States did not master the processing technology of titanium alloys, and the Soviet Union was the major producer of titanium alloys.

Now, with the passage of time, the Soviet Union is also very handy in the use of titanium alloys, and even titanium alloys can be used as the shell of submarines. , a large number of titanium alloy materials are used.

Therefore, it is not uncommon for the Soviet Union's new supersonic aircraft to be made of titanium alloys.

Andre's strange thing is its engine. If you want to fly to higher speeds, the engine is the key!

"General Andrei, your question is very important. Now the Tu-260 we have seen has completed its test flight. It uses four Surorov D-80 turbojet engines. This engine makes the Tu-260 It has a top speed of 4 times the speed of sound, and cruising speed is also 3 times the speed of sound, but it is still far from our requirements.”

It is impossible for such a hypersonic aircraft to use a turbofan engine, and the turbojet can only reach four times the speed of sound. Although the speed is much higher than that of the MiG-25, it still cannot meet the actual combat needs~www.novelhall .com~ After all, the future sky, the threat will be great. Now that the West has developed missiles that can counteract 3 times the speed of sound aircraft, it is impossible for the West to continue to develop missiles that can hit 4 times the speed of sound aircraft after discovering its own reconnaissance aircraft!

It is for this reason that although this aircraft has completed the test flight, it has no finalized equipment. It is only a transitional model.

"The turbojet engine is not good. For high-speed flight, a ramjet is needed." Andre said: "The American Blackbird uses a ramjet."

Sergey nodded: "Yes, General Andrei, you are very right. If you want higher speed, a ramjet is a good choice. However, just using a ramjet cannot adapt to conditions such as take-off and landing, so , we are now testing the variable cycle ramjet, which uses liquid hydrogen fuel, which can allow our current Tu-260 to fly to 6 times the speed of sound. In the plan, we will use this engine model, called Tu-360"

6 times the speed of sound! Andre instantly thought of the crazy Dawn Goddess project in later generations. If it really reached 6 times the speed of sound, it would be an extreme! Existing air defense weapons, even if upgraded, cannot effectively intercept it, unless it is a laser weapon! (To be continued.)
