Chapter 1055 Business jet for military use?

However, Rob Boudin apparently didn't notice Ed Steiner's slight emo side.

For him, who is only responsible for test flight missions, his lifelong interest is focused on exploring the performance limits of a model, and he is not very willing to care about the conflicts of interest in the research and development process.

Therefore, after a short pause, he continued:

"In fact, from my personal feeling, this aircraft is far from reaching its limit. If it performs a shallow dive during the test flight as originally planned, it should be able to break through to a higher speed..."

Robb stretched out his hand and made a downward dive in mid-air.

This somewhat crazy proposal frightened Edsteiner so much that he shuddered and thought to himself that you test pilots are really not afraid of death.

He did think about cheating by doing a shallow dive at first, but that was because according to the estimates at the time, the Falcon 8Z was too large and had a thick fuselage, so its maximum airspeed in level flight could not even reach Mach 0.9.

In this case, the risk is still within controllable range by taking advantage of the tailwind to perform a shallow dive and accelerate.

But now, the actual flight result is about 40km/h faster than the original calculation.

Even though this number is not very high when calculated proportionally, the deviation is less than 5%.

But this is the transonic range.

It is no exaggeration to say that the impact of every 1km/h speed change on airflow and structure is unpredictable.

At least it was unpredictable for Ed Steiner.

It would be fine if it could just keep flying level.

After all, there is no longitudinal overload. Even if you find that the speed has entered the danger zone, you can achieve a smooth deceleration simply by slowly releasing the throttle.

At least there won't be any major problems like plane crashes and casualties.

But if it goes into a dive, the situation will be difficult to predict when it is time to level out.

In case of rudder lock or even wing break...

Ed Steiner just thought about it for a moment and felt a chill down his spine.

If nothing unexpected happens, Falcon Z will be the last major project he is responsible for in his career.

Now that the big plans that were drawn back then have now come true, the remaining task is to ensure that the model can be smoothly implemented and achieve commercial success.

He is too old to do risky things.

"It's still not necessary."

Ed Steiner decisively refused:

"It is sufficient to meet the maximum and minimum speed tests. Now that we have exceeded the design indicator of 0.92, the focus of subsequent tests should be shifted to the allowable envelope range under this speed, rather than blindly continuing to accelerate."

"Moreover, according to our flight control program settings, no matter what the aircraft's airspeed exceeds Mach 0.9, an alarm will be issued and the aircraft will automatically enter the deceleration procedure."

As he spoke, he connected the data recorder that Robb had just brought to a dedicated reading device, preparing to personally confirm the test flight data, and then extract the more eye-catching sections from it to use as promotional material.

"Ok?"

Robb was stunned:

“Is there such a restriction?”

"Well... we added this specifically based on lessons learned from some typical air crashes that happened in the past."

Ed Steiner's answer was somewhat ambiguous, and he obviously didn't want to continue to dwell on this topic:

"Of course they were not installed during the test flight. You test pilots definitely don't need them... But it's hard to say for pilots of commercial airlines... Including the dive you just mentioned, large-angle climbs and dives may be restricted at the flight control level in the future."

Robb next to him suddenly showed a look of enlightenment.

We are all in the same circle.

At this point, it's hard to guess what the reason is.

"Anyway, remember to make arrangements as soon as possible..."

Just as Edsteiner was about to end the conversation, another voice came from behind him:

"In fact, Charles, based on our analysis of the engine operating data during this test flight, the SeA650 has the potential to further increase thrust..."

The two turned around and saw Ian Vista walking out of a small cubicle next to them.

"Of course I know that."

Ed Steiner had a matter-of-fact expression:

"But the Falcon 8Z is already the largest model in the entire series. Even if we redesign an engine with greater thrust, I'm afraid it can only be used for regional aircraft..."

Obviously, he got it wrong.

I thought the other party meant that based on the same core engine, they could design a product with a higher thrust level.

This is indeed something that makes sense.

After all, the SeA650 can essentially be regarded as a non-afterburner model with a small bypass ratio.

Even if nothing else changes, just replacing the fan with a larger one can increase the thrust to 9-10 tons.

There's just no suitable installation object.

But Vesta shook his head:

"It's not a redesign... I mean, judging from the performance, the SeA650 itself can still squeeze out some extra thrust, but it is currently limited by the engine control program."

"Of course, what I see here can only be regarded as some superficial phenomena. For the specific situation, we still need to seek the opinions of our Chinese partners..."

Edsteiner couldn't help but curl his lips, subconsciously wanting to complain that it was a bit inaccurate for the other party to call China a "partner".

But when the words came to my lips, I thought of the situation of Falcon 8Z and felt that I had no right to criticize others.

In the end, I swallowed it back.

Ed Steiner had a "are you kidding me" look on his face:

"The Falcon 8Z can indeed be equipped with an all-weather optoelectronic system, but that is..."

Having said this, he subconsciously glanced at both sides, then lowered his voice a bit:

"That's to transfer the Damocles pod technology to you...No normal user would choose to install it...And in the 21st century, there won't be any madmen who would install two missiles on a business jet to perform low-altitude penetration..."
