Red Soviet Union

Remember【】in a second, providing you with wonderful novels to read.

At three o'clock in the afternoon, the sky was clear and Zhukovsky was full of voices.

Sitting in a shaded tent, looking at the runway in the distance, holding up the binoculars in hand, the highlight of the air show, the flight show finally started.

Everyone stood up from their seats when a red and white fighter plane with NASA on the tail slid onto the runway. What was that? Is it an American performance machine this time?

In terms of appearance, this aircraft is very similar to the F-15, with tall double vertical tails, rectangular air intakes on both sides, and a pilot waving to this side in the bubble cockpit. However, in front of the main wing, that What is the thing? Why is there another pair of small wings? That thing, a little upturned, seems to be able to move? What is this? Canards?

Hmph, as expected, this thing brought the technology verification machine over here! Standing on the control tower, looking at the fighter planes on the runway below, Andre couldn't help but sneer in his heart. Americans, don't they all claim that the best canards are on enemy planes? Even the three-wing layout that Andre rejected, the Americans still tried it!

Of course, this is not the final design, the model of the equipped troops, this thing is just a verification machine!

F-15S/MTD is an advanced technology demonstrator of F-15 short-range take-off and landing and improved maneuverability developed by McDonnell-Douglas for the U.S. Air Force Wright Aeronautical Research Institute in 1984. The verification aircraft is actually to verify advanced aviation technology, and this verification aircraft is mainly used to verify 4 technologies: binary thrust steering/reverse thrust nozzle, integrated flight/propulsion control, uneven/soft field short distance Takeoff landing gear and advanced man/machine interface.

Judging from these items, this technical verification aircraft modified from F-15B will have outstanding maneuverability, and this maneuverability is obtained from the canards in the front and the vector engine in the back!

The full-moving horizontal front wing is installed on the upper wall panels of the air inlets on both sides of the verification aircraft. This horizontal front wing is not newly developed, but is improved from the F/A-18A horizontal tail. The dihedral is convenient for co-directional or differential deflection to generate pitch and roll moments.

At the same time, the F-100 engine at the tail of the aircraft has also been improved. A rectangular binary steering nozzle of carbon fiber composite material is installed, which can deflect the thrust of the engine up and down relative to the longitudinal axis of the aircraft. The maximum deflection angle can reach 20 degrees. Improve the aircraft take-off performance and maneuvering flight performance. Moreover, the thrust-reversing blades in the nozzle can reverse the thrust to realize emergency deceleration and short-distance landing roll in flight, which is similar to the principle of a passenger plane.

In order to control these extra control systems, the original hydraulic operation of the F-15 can no longer accurately control so many systems.

Therefore, this fighter plane also introduced a digital fly-by-wire control system to realize integrated flight/propulsion control, so that the aircraft can change the thrust without changing the original flight trajectory, and realize the control of all flight parameters.

Originally, with the help of a powerful engine, the maneuverability of the F-15 fighter was already top-notch among the third-generation fighters, but after taking these measures, the maneuverability was even better!

Historically, these improvements were almost completed in 1988, and repeated test flights were carried out between 1989 and 1991. But now, under the stimulation of the Soviet Union, the United States has to speed up the development of new fighters.

In the past, the Soviet MiG-25 overwhelmed the Americans, but now, the new generation of Soviet fighters, the MiG-29 and Su-27, are rapidly finalizing and equipping troops. People are under great pressure. In addition to intensively developing their own fourth-generation fighters, the improvement of existing fighters is also the key content. The current technology verification machine is not just for verifying technology. If it proves to be reliable, maybe new fighters will be produced according to this standard.

And now, bringing this plane to Moscow is also to prove to the Soviets and the world that the most advanced aviation technology is still the United States!

Pilot Cruise, sitting on the seat, the tail engine has been started, and there are constantly surging sounds, and his mood also fluctuates accordingly. Since the first test flight of this plane, he has been flying it. Now, he is as familiar with this plane as he is with his own body. As long as he sits here and holds the joystick in his hand, he feels integrated with the plane. up.

Audience, let you experience the powerful performance of this aircraft! For a long time, American aviation technology has always been like alien technology!

Zhukovsky, the eagle is requesting to take off. Cruise said in proficient English. As an international language, English still has an advantage. When communicating inside, we must use English.

You can take off, pay attention to the airspace of the performance, and don't get close to the audience. The voice of the tower came from the earphone.

Can't get close to the audience? If you are not close to the audience, how can you make them feel deeply? Cruise thought to himself. In the current air show, there have not been several serious air crashes in later generations, so Cruise did not take the tower's warning to heart at all.

He pulls the throttle all the way, turns on the booster, releases the brakes, and a few seconds later, pulls back on the stick!

Let's start the show with a short takeoff!

Following his operation, the fly-by-wire system understood what he meant, and took off short distance!

With the improved engine, the thrust has increased by 10% compared to the original one. There is no need to worry about the life expectancy at all. Now it is just a matter of fighting for it! Within a few seconds, the fighter plane accelerated to a speed of more than 100 meters per second! Then, as he pulled the control lever, the front canards rotated to provide the nose-up moment, and the tail fins worked together to tilt the nose! The front landing gear vacated in an instant, and the rear landing gear also left the ground a second later! Then, the nozzle of the engine is deflected downward, pushing the fighter forward while providing upward thrust!

Woke up! That's it!

During the interception operation, the F-15 was fully fueled, loaded with medium and short-range missiles, and had a rolling distance of 274 meters. However, when it was empty and half fueled, it took off within 240 meters.

And now? With the help of the new engine, the vector nozzle, and the canard wings, the F-15 has already pulled the green onions from the dry land and flew up within a distance of less than 200 meters!

Fly up! How can this be! (To be continued.) Mobile phone users please browse and read for a better reading experience.
