When he sat on the seat of the Su-27 again, Qin Feng's heart was full of excitement, as he had done the previous times, he skillfully prepared before takeoff, put the throttle stick in the position of the slow flying car, and then pressed a start button on the right control console, that's right, don't look at the engine of the plane It sounds complicated, the actual start is very simple, this is a one-button start.

  Moreover, this time it was not started with a 26V power supply car on the ground, because now the power supply car in the base is starting another aircraft on the side, so it is the battery that comes with the aircraft, which is almost unimaginable on the previous small plane.

  The start of the engine was not fast, and when the roar of the turbine came from the tail, a minute had passed, Qin Feng looked at the instrument in front of him, and the engine output was only three thousand N The thrust of the slow train was set, and the temperature rose to four hundred degrees.

  Released the brakes and slid towards the runway, after receiving permission from the tower, Qin Feng pushed the engine to the position of maximum military thrust, and then released the brakes.

  In addition to the first flight to start the afterburner, the next few flights, almost no afterburner, because the afterburner of the engine is too oil-burning, which can save some fuel, and, at the maximum military thrust, all kinds of actions can be completed very well, such as now.

  The take-off of the Su-27 is still rapid, its thrust-to-weight ratio in the state of maximum military thrust is comparable to the actual thrust-to-weight ratio of many aircraft, moreover, its aerodynamic layout is excellent, at 200 kilometers per hour, the front wheels have been raised, and when it reaches 250 kilometers per hour, the entire aircraft has left the ground!

  It can fly at a speed of more than 200 speeds, and at the same time, in flight, the minimum speed can also fly to more than 100 kilometers per hour, which is definitely not like a jet to do it, and it is already very good for a propeller plane to have such performance.

  Take J-7-J-8 as a comparison, this speed is more than 300, and it is also when landing, so if the attitude is not well controlled when landing, it is easy to burst the tires, in contrast, the flight of the Su-27 is so easy and smooth!

  After taking off, he continued to raise the altitude, and when he reached an altitude of three thousand meters, Qin Feng said to the rear cabin: "Request to fly the cobra maneuver!" ”

  Finally about to fly this most famous maneuver, Qin Feng used his best strength to calm himself down, trying not to make any mistakes, after getting permission, he glanced at the airspeed meter, four hundred kilometers per hour, just in line with the required speed, now, disconnect the angle of attack limiter!

  Pushing the throttle to the eighty-fifth percentile position, Qin Feng pulled the operating lever back into his arms, the sky in front of him was rapidly flipping, the earth left the field of vision, all were the sky, and his angle of attack was rapidly increasing, thirty degrees, sixty degrees, ninety degrees! When it reached ninety degrees, Qin Feng glanced at the airspeed counter, and it had already been reduced to one hundred and fifty kilometers per hour!

  You can't go any further, and if you go any lower, it's time to get into a stall tailspin! Qin Feng was still a little unwilling in his heart at this time, what was going on? People fly cobra maneuvers, can exceed 90 degrees, 100 degrees, and even up to 130 degrees, but what about themselves? If you fly this time, you can only fly to a 90-degree angle of attack, and you can't break through? This kind of action is imperfect, only the nose is backward and the tail is forward, it is called a cobra maneuver!

  He pushed the throttle, operated the lever, changed the Cobra maneuver, and then, continued to fly other actions, this was the last time he flew the Su-27, and after flying this time, it was time to enter the professional training of stall tailspin.

  Unexpectedly, the last action was not perfect enough.

  In addition to this action, Qin Feng continued to do other actions very well, driving to the maximum thrust, entering the maneuver of breaking s, the plane entered and exited steadily, without any jitter, followed by half a Cuban figure, driving the maximum military push and pull to 65g. Another 7g 360-degree small radius turn, in the past few days of flight, he has fallen in love with this aircraft, only a high enough thrust can give the plane unparalleled maneuverability!

  Looking at the airport from afar, this flight has come to an end, Qin Feng aimed at the runway, and then opened the speed brake on the back of the plane.

  There is a huge speed brake on the back of the fuselage of the Su-27, which is used for landing, and it can also be opened if you want to deceive the opponent in air combat, but in the current energy maneuver theory, it is very stupid to take the initiative to reduce your speed.

  The speed was reduced to three hundred kilometers, Qin Feng divided the landing gear, opened the flaps, the speed continued to decrease, and when it fell to the ground, the speed had been reduced to two hundred and thirty kilometers per hour, which was a very perfect landing!

  When the plane stopped on the tarmac, sitting on the wide seat, looking at the cockpit canopy slowly rising overhead, Qin Feng didn't want to get up anymore, after going down from here, I don't know when I will be able to fly again!

  "What, you are still reluctant to go down?" Pugachev in the aft compartment shouted to him.

  If you don't come down, how can the ground crew take over the maintenance?

  Qin Feng stood up, climbed down slowly, and then, with one last glance, looked at everything in the cockpit, as if bidding farewell to his lover, and walked down step by step.

  "Instructor, why can I only pull my movements to 90 degrees?" Qin Feng looked at the plane reluctantly, and then asked Pugachev, this is also the strangest thing about him, why can't he fly as gracefully as Pugachev? Where did you not do it?

  Qin Feng pursues perfection, which is also where he feels that he has regrets.

  "You've done a great job, it's mainly a matter of the plane, if you fly a single-seater Su-27, you will definitely be able to pull it to more than 100 degrees." Pugachev said: "We flew a two-seater Su-27, and today, we don't carry much fuel, which is mainly stored in the front, so it is not easy to pull the plane to the back with the center of gravity in front." ”

  I see! Qin Feng immediately understood, it was not his own problem, it was the problem of the fighter! It's like riding a motorcycle, where the rider can get the front wheels off the ground, but if you add a counterweight to the front of the bike and make the front of the bike weigh too much, you won't be able to lift the front of the bike.

  However, when will the single-seater Su-27 be flown on?

  This idea can only wait until later, anyway, the Su-27 has returned to China, he still has a chance in the future, now, let's go to the last difficulty!

  The various theories of the tail spin test flight laid the foundation for the tail spin of the J-10 in the future! Even if Qin Feng flew before, it was not systematic, and now that he is here, he has to learn systematically.
