Chapter 1350 Heavy Duty Race and Endurance Race

After all, GE is still a super-large company with a market value of more than [-] billion U.S. dollars. Its roots are deep and leafy, and it has influenced the world for decades. Compared with Kelin Aviation, it is still not the same size. Even if the stock price is close, the scale of the two parties is not at the same level. .

And there will certainly not be only one company in the future personal flying vehicle market.

No company in the world can fully meet the needs of everyone in the world. It is normal to have one superpower and many strong ones.

After the sprint race, it entered the second round of the regular season, the load race.

This is more complicated.

Different aircraft, different flying methods, have different competition standards.

As for the aircraft using mini-turbofans, after discussions with experts, a special competition method was directly used.

Two games of load and battery life in one!

A few planes filled up their fuel tanks before hanging up the counterweight as appropriate.

As long as it can take off successfully, it is considered a valid result.

Everyone knows how much their own aircraft can carry.

Considering the scene and the wind force, the contestants nervously calculated.

Soon, several aircraft took turns to weigh and weigh.

"Air killer: 79.7 kg."

When the data was announced on the spot, the audience was also in an uproar.

"Fuck, this is already close to [-] kilograms, can it be so heavy?"

"Isn't the thrust of the canned turbofan only 30 kilograms? How can such a heavy thing fly?"

In fact, the aerial killer is also a giant, much larger than ordinary model airplanes and aircraft.

Folded, disassembled, and packed separately on weekdays, it is still an oversized and overweight box.

Now it is fully extended, full of oil, and weighs almost as much as a relatively strong adult boy.

The thrust and weight are not proportional. This ratio has a name called the thrust-to-weight ratio, which is the engine's thrust/maximum take-off weight.

The thrust of an aero-engine is completely different from that of a rocket.

Due to different flight modes, aeroengines can take off with the help of runways and use wings to provide lift. Therefore, the thrust-to-weight ratio of commercial aircraft is often 0.2-0.3.

Because fighter jets require powerful maneuverability, the thrust-to-weight ratio is often above 1.

In other words, theoretically all fighter jets can take off vertically.

The thrust-to-weight ratio of the aerial killer has also reached about 0.4, which can be said to be very strong.

If it is designed better and the runway is stronger, it can continue to increase the take-off weight.

But the runway of the entire stadium is so long, and the wind direction today is still downwind, which is not suitable for takeoff, so that's all.

Over there, the data of the white falcon also came out: "82.1 kg".

"So heavy? Heavier than an aerial killer?"

"Can this fly?"

It has to be said that these two aircrafts have become the stars of the live competition and the wind vane that everyone pays the most attention to.

Other aircraft, and their take-off weights, are not in the same class.

After the weighing, the air killer took the lead to enter the take-off runway.

Yan Xuexin, as the operator, placed the aerial killer on the starting line for takeoff.

This time, instead of urging him, the staff let him take off on his own.

Beside, Makuka measured the wind direction and speed.

When the wind direction clearly turned against the wind, Makuka nodded, and the Sky Killer's engine was ignited, and it began to fly forward.

In fact, for an aircraft, the most important thing is not the ground speed, but the air speed.

With the help of the headwind, the wind speed is increased, the length of the runway is increased, and the take-off weight of the aircraft is increased.

However, Yan Xuexin was obviously unlucky, the wind direction suddenly changed while the plane was accelerating.

Although there was only a slight breeze today, it still caused trouble for Yan Xuexin.

Beside, Ma Kuka hurriedly reported the wind speed and direction, while Yan Xuexin watched the speed displayed on his remote control screen and silently calculated.

Ahead is the end of the runway, almost brushing the red line of the runway, the aerial killer flew off the ground!
Next to it, on the big screen, the take-off time and the weight of the successful take-off are displayed.

The continuation race has officially begun!
Seeing the aerial killer staggering and finally flying, Yan Xuexin subconsciously wiped off his sweat.

Fortunately, it's flying!
Just fly and nothing can stop it!
Take off successfully, 79.7 kg!

This is already the best result of the aerial killer so far. At MIT, when they conducted experiments, the maximum load was only 78 kilograms.

Over there, the white hawk was whistled.

Before taking off, the white hawk crossed the line.

Each aircraft has only three take-off opportunities. If it fails to fly three times, it means that the load challenge has failed, and the results of this competition must be given up.

Visible to the naked eye, the people in the Harvard team were sweating on their foreheads.

Refuel, reweigh, take off again.

Press the line again!

The third time, 80.1 kg, finally took off successfully.

On the rostrum, someone uttered a low voice: "Okay!"

Finally, it overwhelmed the canned turbofan and overwhelmed the aerial killer!
Although it is only a 0.4 kg advantage.

"Well, if only we were bolder." Seeing the other party's results, Lixia felt a little regretful.

A successful takeoff means that this has not yet reached the limit of the air killer. If you add more weight, it should be able to fly.

"It's okay, we have already won a victory." Yan Xuexin is not greedy for too many, and there are different scores when scoring multiple takeoffs and one takeoff.

Next, there is no need for any difficult operations, just let the aircraft ensure a stable cruising speed.

He moved his tense and stiff hands, and handed the remote control to Lisha.

The competition system of this continuation race is also very simple, which is to circle back and forth between two points AB.

In the middle of the two playgrounds, in the sky, there are two flying swords standing in the air, serving as indicator poles.

All flying machines have to go around these two flying swords to complete a circle.

Combined with GPS positioning and the distance between the two, the cruising range is comprehensively calculated.

On the large screen next to it, various current parameters of the aircraft, such as mileage and ground speed, are displayed.

At the beginning, only the sky killer was flying, and everyone didn't feel it yet.

But when the white hawk took off, everyone found something was wrong.

"Hey, why is the white falcon a little slow?"

"This speed is the most economical and fuel-efficient speed."

"The cruising speed difference between the two is so much?"

On the big screen, the aerial killer has been maintaining a speed of about [-] kilometers per hour.

But the speed of the white hawk is less than 200 kilometers, more than 100 kilometers.

"This is a bit interesting..."

Everyone is sensitive to what is happening.

That is, compared with the canned turbofan, the limit output of the two is similar, but... MF-101S consumes much more energy!
