Chapter 235 Extreme Test

When Kangchi designed Yinhe in Dongyang, because there were no wind tunnel conditions for actual testing, he only conducted a few computer simulation tests.

The biggest test in the fixed-wing state is whether the design of the fuselage complies with aerodynamics, so what Kangchi is most worried about is this inconspicuous test.

However, there is a wind tunnel laboratory at the Aoying base, so before the actual test, Kangchi asked Yinhe to be taken to the wind tunnel laboratory and conducted a wind tunnel test to confirm that the deviation between the test results and the simulation was within the acceptable range. Only then did he pull Yinhe to the testing site again.

Since the wind tunnel test has been passed, there is basically no suspense about this test.

With the dual motors running at full power of 3000 horses, Yinhe's gliding take-off distance was only 67 meters. When gliding and landing, the electric motors reversed braking and achieved an astonishing stop of 23 meters. .

This made Cai Yaobin become more and more fond of the Silver Crane. If it hadn't been for the most critical aerial deformation test, he would have placed an order with Kang Chi immediately.

Of course, even if there is an accident in the subsequent mid-air deformation, he will definitely support Kang Chi in continuing his research in this area. This is not only out of trust in Kang Chi himself, but also his love for this aircraft. .

"Preparing for mid-air attitude change testing."

"Roger that!"

As the testing process progressed, it was finally time to test the core functions of this aircraft.

"Success!"

Kang Chi: "..."

However, the performance of Yinhe's body stabilization system is as reliable as usual.

"..."

"Report to the tower, the current speed is 300 kilometers per hour, the flight altitude is 2234 meters, and the flight attitude switching procedure has begun."

"One mode switch directly caused the helicopter to reach a speed of 460KM... The tilting rotor is really powerful!"

He may have almost forgotten that Kang Chi originally built this Yinhe to have a convenient private transportation...

"Mr. Kang, congratulations!"

When the propeller of a tilt-rotor aircraft changes direction, changes in wind force will make the airflow environment faced by the entire fuselage extremely unstable and complex. If the stability of the fuselage is not sufficient, violent shaking will easily occur. Even flipping over or losing control.

"Mr. Kang is mighty!"

About twenty seconds later, Yinhe finally completed the transition from helicopter state to fixed-wing state. The reduction in wind resistance and the change in power direction also allowed Yinhe to soar in speed with the same power output.

In order to observe the process and stability of Yinhe's deformation in the air, the test team also arranged for a K8 trainer aircraft to fly with it for filming and transmitted it to the large screen in the command room.

can only say,

As expected of the leader of the Equipment Procurement Department, he arranged the application scenarios so quickly and even started to consider possible problems on the front line.

Upon hearing Li Xiangnan's report, the entire command room was immediately drowned in cheers.

"Reporting to the tower, we have successfully switched to fixed-wing flight mode. The current speed is 460KM and the flight altitude is 2323 meters."

"makes sense."

Cai Yaobin couldn't help but look at Kang Chi with excitement: "Although the stability and interference resistance of electric aircraft on the front line have yet to be tested, this aircraft definitely has huge potential in terms of border patrols, rapid troop transport support, and logistical supplies. potential!"

"Well... I think we should not get too happy yet. There are still many tests to come."

"I didn't expect that we also have aerial Transformers!"

Through real-time detection and adjustment of the fuselage status in milliseconds, Yinhe's fuselage stability has been maintained perfectly, without any large swings.

As Li Xiangnan began to perform the operation, the two motors on the Yinhe wings that were perpendicular to the ground began to slowly rotate ninety degrees.

When Cai Yaobin turned back and continued to look at the big screen, Kang Chi's brows began to frown slightly.

After switching to fixed wing, the speed increased to 460km/h. This data seemed to be a bit inconsistent with what he expected...
-

If you can change from a helicopter to a fixed wing, you will naturally have to change from a fixed wing to a helicopter.

In this test, Yinhe finally encountered its first problem since the test.

However, the problem was not that big. The main reason was that the change in shape caused the aircraft's power and speed to drop sharply, causing a small stall and fall.

After the test, Kangchi spent half an hour on the spot modifying and correcting the flight control program. First, the speed when switching to helicopter mode was reduced to 380KM/H, and then when switching to flight mode, the range in which the flight control system adjusted the motor power was widened.

After the modifications were completed, everyone conducted the test again, and the problem of stalling and falling was indeed solved.

Next, it’s the ultimate test.

During this test session, the aircraft will switch from semi-autonomous driving to fully manual mode, and at the same time disable most of the safety auxiliary functions so that test pilots can test out the ultimate performance of Silver Crane.

"Finally it's time for us to perform!"

After entering this session, Li Xiangnan and Shen Ye finally started to feel a little excited.

Although the previous tests were somewhat dangerous, because Yinhe has a relatively high degree of automation and the test of operating skills is very low, it can be used even if Kangchi is replaced.

This is indeed a bit boring for the two people who often fly supersonic fighter jets.

But the next test started to get a little interesting.

"Yinhe, conduct the ultimate lifting test!"

"Received, starting the extreme lifting test... 10 degrees, 20 degrees... 88 degrees! The current speed is 166KM!"

"Speed ​​434KM, ground radar overshoot!"

"Damn it, this is too fast!"

When everyone in the command room saw that the fixed-wing Yinhe turned into another form of 'helicopter' after being lifted up, climbing up at an angle almost perpendicular to the ground, and reaching a speed of up to 166KM per hour, Suddenly there was another burst of exclamation.

Next, under the control of two top pilots, Yinhe was really like a light crane, performing various dives, rolls, barrel rolls and other difficult acrobatic movements that fixed-wing aircraft often do, and at a basic speed of They were all over 400KM, and Kang Chi couldn't help but sweat for the two test pilots.

"Start the ultimate acceleration and maximum speed test. The current speed is 200 kilometers per hour, the altitude is 4556 meters, and the switch has been pulled to the maximum!"

As Li Xiangnan pulled the switch to the maximum, he felt a strong pushing feeling on his back.

"The acceleration is so fast!"

Li Xiangnan never expected that when testing a tilt-rotor aircraft, he would experience such an exciting feeling.

"Speed ​​280km/h, 350km/h...598km/h! Top speed 598km/h!"

"598km/h!!?"

When hearing this number, not only the people in the command room were stunned, but even Kang Chi showed a surprised expression.

In fact, Kangchi vaguely noticed something was wrong when he changed the form of the test before, because the speed in the helicopter form was 300KM/h, but after switching to the fixed wing, the speed increased directly to 460KM/h.

In helicopter mode, Yinhe's top speed is 400KM. Based on this ratio, Yinhe should be 613km/h in fixed-wing mode.

But Kangchi clearly remembered that the maximum speed written on the system panel was only 500KM/h.

Kang Chi thought about it and felt that the data given by the system panel was probably the maximum speed with a full load of 9 tons.

After all, if you want to measure this kind of limit speed, it will probably be affected by the number and weight of the pilots, and there is no way to specifically measure the limit speed without a load.

It seems that the parameters given by the system panel in the future can only be used as a reference and should not be trusted or relied on too much...

But in any case, it is definitely a surprise to be able to reach a speed close to 600km/h. You must know that the speed of the Osprey is only 510km/h.

However, the two are actually not the same weight class. The empty weight of the Osprey is 15 tons, while the Silver Crane is only 5 tons.

If Yinhe is enlarged to the level of Osprey and a few more tons of batteries and motors are installed, it may not be able to reach the speed of 600km/h.

Of course, there is also the possibility that the speed can be faster because of the addition of motors and propellers...
