Chapter 259: Prototype Test Flight
These guys have always prided themselves on being the pride of the sky, and they are empty-eyed, and what is the concept of people in this era who can fly an airplane in the blue sky is simply a later generation Yang Liwei drove a spaceship into space.
Wearing a flying jacket and a specially designed flying helmet, walking in the area of the Dragon King Temple is envied by everyone, and he is dragged to death. After a long time, no one's words are taken seriously, of course, Hu Wenkai's words do not dare to disobey, no matter how arrogant he is, he knows that he is a pilot trained by Hu Wenkai.
"It can't be true, right?" Diao Yuanjun's mouth was half-open.
Old Pete said: "I only have one engine piston engine in the United States, and the horsepower is only 45kw, you don't naively think that my technology will improve by leaps and bounds in two years, from the primary piston engine can directly build a V12 two-stage turbocharged engine, right?" I'll tell you that these are all drawings provided by your boss and developed under his guidance. ”
The pilot was stupid, he couldn't believe that it was actually designed by the boss Hu Wenkai, this plane is simply the pinnacle, Diao Yuanjun was itching in his heart to go up and fly to the sky, so he deliberately made trouble with the pre-flight theoretical study of old Pete, he didn't want to waste time on this red tape, the plane was not like that, as soon as the throttle was pressed and the lever was pulled, it went to the sky.
Since the aircraft was designed by the boss, I had to sit here honestly and listen to the old Pete explain the structure and operation of the aircraft, and dissect the structure and power system of the aircraft for seven consecutive days either next to the plane or in the classroom. Old Pete talked about the hardship, and the pilots asked in detail, Diao Yuanjun actually asked when the tire pressure on the landing gear of the plane should be conducive to takeoff.
In the next few days, Diao Yuanjun and the four selected test pilots climbed onto the stationary plane to familiarize themselves with various instruments and control systems. Dozens of pilots as a whole memorized passwords, instrument names, and roles in addition to eating.
Early one morning in mid-August, the first fighter prototype of Longwang Temple was ready for the maiden flight. It was a typical Jiangnan summer morning, with only thin clouds floating at low altitudes, perfect for flight tests.
The prototype was towed from the factory to the runway side of the Longwangmiao Airport, and the elder Pete gathered around the plane with members of the design team, as well as pilots of the flight group and officers of the staff headquarters, most of whom were witnessing the newborn born from his own hands for the first time. The prototype retains the original color of aluminum alloy, and the graceful and smooth body is smooth and shiny, standing quietly in the cool breeze, like a battle-hardened horse waiting for the moment when the starting gun is fired and gallops.
Diao Yuanjun put on a tight-fitting and comfortable flight suit and climbed into the cockpit. After the V-1710 engine was awakened from its slumber, he closed the canopy of the aircraft. The plane glided briskly towards the end of the runway, and as the engines roared, the air currents from the propellers blew up the stagnant water that had gathered on the runway from the previous night's rain, splashing up puffs of droplets.
All the equipment was working normally, and Diao Yuanjun obtained permission to take off and taxied the plane to the position of the parallel runway. He held on to the brakes and steadily pushed the throttle valve, the engine roaring louder and louder, and large clouds of black exhaust fumes gushed out from the exhaust pipes on both sides of the hood.
When the time to take off came, Diao Yuanjun released the brakes, and the plane was like an arrow off the string, sliding rapidly on the runway. As the speed increased, the tail wheel of the aircraft detached from the ground, and Diao Yuanjun found that the torque effect of the propeller was much smaller than expected, and he could keep the plane taxiing smoothly in the middle of the runway without difficulty by exerting a little control on the rudder.
The long concrete runway under the wings was thrown behind, the main landing gear wheels lifted off the ground lightly, and the plane leapt gracefully off the runway and flew into the endless blue sky.
After witnessing the plane's landing gear retracted into the wings with unerring accuracy, the pilots and aircraft factory workers on the ground erupted in a storm of cheers and applause.
Diao Yuanjun found that the plane accelerated faster than expected and climbed at a steeper angle, so he had to retract the throttle valve slightly to ensure the safety of the flight. After 20 minutes of experience piloting the plane, Diao Yuanjun gradually became familiar with the flight characteristics of this aircraft, and he formed a formation with another aircraft accompanying him and began to fly in unison.
At this time, the ground tower issued instructions to Diao Yuanjun, requiring a series of maneuvering flights within the observation range of the ground. For any action made by Diao Yuanjun, this aircraft can respond quickly and quickly, and its performance far exceeds the expectations of the engineers. In the end, Diao Yuanjun piloted the plane to land on the runway of Longwangmiao Airport with a beautiful three-point landing, and the fighter's maiden flight came to a flawless end.
With the help of the ground staff, Diao Yuanjun stepped on the spiral ladder and walked to the apron, and was picked up and thrown into the sky by the pilots who came, throwing it up and catching it and throwing it up, so excited that just watching the take-off and landing can feel that the horsepower of this aircraft is amazing, and the control is like a shadow.
Here, the engineers took the screwdriver pliers and drilled into the cabin of the plane to start the inspection, recording first-hand information.
Old Pete's team brought Diao Yuanjun to the conference room and began to ask various questions, Diao Yuanjun was qualified to be the first test flight aircraft, and needed to explain various flight phenomena theoretically, accurately report the flight situation, and put forward suggestions for improvement in the test flight, in addition to completing the flight action safely as required.
This is impossible without a high level of theoretical knowledge and a full understanding of the aircraft of the average pilot. It is the direct executor and monitor of flight tests, and the most important arbiter of test flight results and conclusions. In a sense, the success or failure of a test flight depends largely on the test pilot.
Diao Yuanjun opened his mouth to describe: "Piloting a sparrow is like riding on the back of a cow, and flying this plane is like riding on a humane horse, all the actions are easy and elegant." ”
After a detailed inquiry, the elder Pete said: "Tomorrow the flight test flight of the flight qualities of the aircraft will begin. ”
The flight quality test of the aircraft refers to the ability to ensure the flight safety of the aircraft and complete the flight mission, and the maximum speed of level flight; It is an important symbol to prove the combat performance of a new aircraft, and this kind of test flight is under the condition of "maximum" or "full afterburner" of the engine, and the stable level flight speed that the aircraft can achieve is the maximum ceiling of level flight; Refers to the maximum altitude that an aircraft can rise
Old Pete's sentence shows that the degree of satisfaction with this aircraft is extremely high, generally to carry out the flight quality test flight of the aircraft at least two or three times before the test flight, after the ground full analysis and test, through the test flight to verify whether the predetermined functions and indicators are achieved.
Now it's good that old Pete jumped directly over this link, and directly carried out the flight quality test flight of the aircraft, in fact, old Pete watched Diao Yuanjun's test flight today, and always felt that this aircraft was a mature aircraft.
For the rest of the week, the aircraft spent five hours a day in the sky, diving from high altitude to low altitude at high speed to obtain maximum longitudinal acceleration, and the prototype let out a low roar full of power. This is a low-altitude high-speed flight carried out by test pilots to test the structural strength and design indicators of the aircraft.
Old Pete no longer went to the Dragon King Temple Airport to watch the test flight, he really felt that there was no need to waste his time, this plane was simply brought out of the mother's womb, the power ceiling and power altitude flight was over, and the old Pete handed over the work to the assistant and never came again.
That day was a hairy young man test flight, from the height above the static ceiling, the speed increase to the maximum speed, the use of the aircraft's kinetic energy, along the jump route rushed up, in order to ensure that the aircraft does not lose stability, maneuverability under the circumstances, the maximum altitude that can be reached, the power ceiling and power altitude flight test flight is estimated in the world there is no more fierce than this aircraft.
The plane was handed over to Diao Yuanjun, and the flight team was responsible for writing the flight manual, and after a sortie, the test pilot must write a few hundred words of flight feelings, how long the stall will drop, the minimum turning radius, the maximum elevation angle, and the standard process of various actions, which need to be written out by Diao Yuanjun's test flight team one by one.
After getting the first-hand test flight information, the old Pete immediately began to build the second prototype, and there were hundreds of major changes without small changes. He accepted Hu Wenkai's suggestion to add bomb hooks under the wings, and Hu Wenkai always liked to use one plane for multiple purposes, and the first transport plane, the Sparrow, was both a bomber and a transport plane, and now it is also a passenger plane.
It is impossible for Hu Wenkai to let go of all the surplus value of an airplane, how can he only use this fighter as a fighter plane, the bombs hanging under the wings are named after the boss fighter-bombers, and the weight of the entire fuselage is greatly reduced by using a large amount of aluminum alloy, and the reduced weight can be used to increase the bomb load.
The elder Pete organized engineers to test the airframe, and he was already thinking about where to fold the wings, and how to modify the drop-shaped cockpit to affect the take-off line of sight and the sight line of sight of the landing to land on the aircraft carrier.
He has already considered how to transform this aircraft into a carrier-based aircraft, he and Hu Wenkai have the same virtue, an aircraft must squeeze out the surplus value. Holding a pencil in his hand and sketching on the drawing board, well, a *, can be hooked under the belly of the machine, the size and weight of the * are not known, he wants to pass through the naval base, people say that military secrets want to know the door.
Old Pete yelled angrily into the phone: "Damn, don't forget, Lao Tzu is also a citizen of the Republic of China." ”
"Are you a soldier? Otherwise, there is no door. The other party hung up the phone directly.
Old Pete wanted to find Li Manqiang through the staff headquarters, and Li Manqiang heard that this was the case and said: "Old Pete really can't be the master of this matter, it is the rule set by the boss." In this case, I will go to Chen Jiaxiang to take a look, but you have to write a letter of confidentiality. ”
"Li Manqiang, let me tell you, the degree of secrecy of my plane is several times higher than that of his broken *, but I am carrying out the tasks assigned by the boss, I have a note written by the boss, and all departments must assist me."
"Old Pete, don't worry, your strip works, you can borrow money and borrow people, but you still can't know military secrets. I'll contact Chen Jiaxiang in a moment. ”
