"Flight status is stable."
"Good flight attitude."
"Flight altitude, 13,000 meters."
At this moment, in the main control console at the rear, each person reported on the data of the sixth-generation fighter jet that had taken off.
Su Jianjun picked up the walkie-talkie directly.
"Calling the gyrfalcon, calling the gyrfalcon."
"Haidongqing received, please speak!"
"Now we will fly to an altitude of 15,000 meters and begin the first test!"
"Received, Haidongqing".
After receiving the instructions from the ground, Yuan Yi immediately accelerated and flew into the sky.
After the fighter jets reached an altitude of 15,000 meters.
The ground team launched another air route link towards Yuan Yi.
You should know that there are many aircraft flying in the sky, and without a flight path, it's impossible for you to take off at will.
If an air crash occurs, the plane will simply fly onto another passenger flight route and be done for!
"Airline route being received."
An AI-generated voice came from inside the helmet.
"Airline route received."
Yuan Yi quickly tapped a few times on the electronic screen in front of him.
"Haidongqing route received, please provide instructions!"
"We will now begin supersonic flight at normal cruising speed, gradually accelerating after five minutes!"
"Received, gyrfalcon!"
Yuan Yi pushed the throttle valve directly, and then the speed began to increase little by little.
Normal cruising speeds: Mach 0.5, Mach 0.8, and Mach 1.
It directly enters supersonic cruise mode.
Mach 1, Mach 1.5, and Mach 2 are normal supersonic cruise speeds.
After flying at a normal cruising speed of Mach 2 for five minutes, Yuan Yi received another order from the ground.
Previously, it was operating with two pulse detonation engines.
The third engine was started immediately after the order was received.
The three pulse detonation engines immediately began to operate at full speed.
Yuan Yi went even further, pushing the throttle valve all the way to the bottom and increasing the throttle output power.
Vector propulsion pulse detonation engine unleashes its full power.
The Ginkgo Leaf sixth-generation fighter jet began to fly rapidly, trailing a sonic boom.
Mach 2.5, Mach 3, Mach 3.5.
The fighter jets sped up, leaving a trail of afterimages in the air as they roared past, accompanied by sonic booms.
At this point, the fighter jet's exterior surface becomes increasingly hot due to its supersonic flight speed.
The aircraft has airflow for heat dissipation on its exterior, and naturally, it also has the heat absorption function of the fighter jet itself.
However, the temperature on the exterior of a fighter jet will not affect the temperature control system inside the cabin, regardless of the temperature.
Yuan Yi stared at the fighter jet's instrument panel, reading Mach 3.5, Mach 3.6, Mach 3.7, and finally breaking through Mach 4.
And it's still hurtling towards Mach 4.
Looking out through the canopy of the fighter jet, the surrounding scenery was already too blurry to see clearly.
"Beep beep beep, beep beep beep, beep beep beep."
At that moment, a radar alarm sounded in the cabin.
"Calling the gyrfalcon, calling the gyrfalcon."
At that moment, an emergency call suddenly came through the communication channel from Su Jianjun.
"Gyrfalcon, slow down!!"
"Gyrfalcon, hurry, slow down!"
Although Yuan Yi didn't know what was going on, he still obeyed the order.
As soon as the throttle was released, the fighter jet's speed began to gradually decrease from Mach 4.
It continued to descend until it reached normal cruising speed.
Yuan Yi pushed open the visor on his helmet.
"Calling Number One, what's going on?!"
What Yuan Yi didn't know was that this was also the first time this sixth-generation fighter jet had broken the Mach 4 supersonic cruise speed since it was produced.
The alarm that just sounded in the cabin was a direct warning from the ground.
Su Jianjun was indeed a bit foolish; he originally intended to fly towards the other party for the first time.
At most, it can only fly at Mach 3 or Mach 3.5.
But who could have imagined that this guy would be so fierce, not only going straight to Mach 4, but also rushing towards Mach 4.5.
Although they knew that the three pulse detonation engines working together could reach a top speed of Mach 6.
But none of them had tried it before!
It's only theoretically feasible; in reality, a fighter jet carrying nearly fifty tons of empty weight can still be this powerful.
To be honest, Yuan Yi hadn't been paying attention to his speed.
He simply followed orders, pushing the throttle valve all the way down and flooring the accelerator.
Then I felt myself being pressed firmly into the cockpit seat.
I must say, this feeling of extreme speed is quite exhilarating.
"What? Are we going to conduct a supersonic test flight again?"
Yuan Yi asked Su Jianjun directly.
"Wait a moment, we're recording the data here!"
Yuan Yi shrugged and began flying at a normal speed.
Unbeknownst to him, the ground control center was already in an uproar because of his actions.
The staff are constantly recording data and monitoring the values of the three engines, among other tasks.
It took Yuan Yi ten minutes to hear Su Jianjun's voice again.
"Calling the gyrfalcon, calling the gyrfalcon."
"Received, Haidongqing".
"Can we re-enter supersonic cruise, this time at a slower speed?"
"From Mach 3 onwards, follow my orders and gradually increase the speed."
Upon hearing the words on the communication channel, Yuan Yi immediately pulled the control stick again, performing a somersault that allowed the 50-ton empty fighter jet to perform a high-G maneuver.
