Is there no drawback to the AF990's powerful data?

Eric was the first to object, the biggest problem with this seemingly epoch-making engine is that the fuel consumption is too large, the professional point is the fuel consumption rate, the professional shop is the thermal efficiency, and the professional point is the total efficiency, and the total efficiency of the F990 is a problem, so whether this aircraft can have a certain reference value, rather than really creating a unique big money consumer is a problem that needs to be improved again.

A large part of the expert team was thinking about improving the engine, and these people involved in the development and improvement of the team passed many screenings by the Ministry of National Security before being invited by Junkers and Dinah to participate.

"Mr. President, the test has begun." After Junkers finished giving the order, the people around him shook the flag in their hands, and the control center began to operate.

Erik, who was observing through the thick glass, noticed that the problem with the plane immediately appeared, and he trembled violently.

"Are you aware of this?" Eric thought that Junkers had not discovered the problem in advance in theoretical tests.

"This scheme is already a lot better than before, we have lengthened the wings, so that the effect of tremor is much lower." Junkers' answer left Eric a little baffled, does this problem need to be solved by lengthening the wings? What length do you have to add to?

"Why don't you consider adding ailerons, uh... I'm not talking about the flap, it's the diversion of the tail end of the wing, you try. After Eric finished speaking, he asked people to stop the test and then took everyone to the scene, and personally used adhesive tape to stick a material plate on the end of the wing, and then explained: "This is actually not difficult to understand, observing the eagle's flying movements, you can understand that the eagle's favorite hovering place is the high-pressure area, the rising force and air flow will squeeze and deform the eagle's wings, forming a turbulent current at the end of the eagle's wings, At this time, the wings at the tail of the wings will adjust the angle of upturn according to the change of airflow, so that the turbulence can avoid the intersection with the lifting force as much as possible. ”

Eric explained to the model, made the eagle flying, and used his fingers to demonstrate the tail of the eagle's wings, so that everyone was both clear and amazed by the president's talent.

It is not surprising to say that the harvest is very large, because the speed of the aircraft at this time is generally not high, and the composite materials used in the Lufthansa 1 plan are both strong and much lighter than all-metal structures, such shortcomings are really not surprising, but once the speed of the aircraft begins to climb with the innovation of technology, the role of these stable aircraft will become more and more obvious, so that everyone can avoid a lot of unnecessary troubles by understanding it earlier, and it can also make the German aviation industry go faster and smoother.

Eric didn't intend to hide it when he explained this, and unless you were an airplane that would never be seen by others, it was only a matter of time before it was borrowed.

Under Eric's mixing, the model with wingtip rockers had a significant effect on turbulence in the following wind tunnel tests, and the tremor amplitude was much smaller.

"Mr. President, this design is just one of them, and the next one..." Junkers wanted to continue to show Eric their design results, but Eric didn't want to look at it anymore, and provided the engine and fuselage materials, only one design was missing, such a simple thing, Eric didn't want to spend too much thought, the main reason for coming this time was August Horch's invitation.

"Thank you very much, the Lufthansa 1 project is less than half a year away, please continue to work hard and seize the time." Eric politely said goodbye again and did not forget to encourage everyone before saying goodbye alone, leaving his wife alone on the scene to preside over the overall situation.

Leaving the ALM base, Eric got into a shiny black Benz Extended Limited Edition sedan under the escort of the Security Bureau, which was said to be limited but was actually the only one, a car specially built by the Benz company for the president, with thick armor and sufficient power.

The car quickly drove to the weapons test site, where Horch and several of his designers were waiting at the door. For Horch, Eric both likes and hates, likes the spirit of daring to create, and hates the creation while completely ignoring the needs of reality, so many times the design presided over by Horch has fallen into an embarrassing situation, just like the previous 30MM cannon, which is simply a weapon that the current Wehrmacht cannot be equipped on a large scale, air defense is not used, anti-armor is average, anti-infantry is a waste of money, and it is not strong enough for the aircraft, and the plane has to fall apart as soon as the gun is fired.

"I was really touched by the fact that Mr. President was here in person." Horch has long forgotten when Eric refuted him in person, but thanked Eric for his many instructions, and after returning home, Horch made many rectifications to the RM-105, and changed the RM-91 and RM-150 to a larger caliber according to Eric's design, and the style of the two is no longer the same.

"Let's go, I'm very short on time, I'm chatting while watching the test, I'm the only one who came this time, and you don't have too much hope, after all, it's the Ministry of Defense who wants to sign an order with you." With the experience of the last time, Eric first said the ugly things in front of him, and also shifted the responsibility, for fear that another blow to Horch would make Rhine face an embarrassment. Eric hates Horch, but he doesn't hate the Rheinland company, Horch is just an investor and designer who took advantage of a large number of orders after the war to get rich, the main focus of the Horch company is the manufacture of small arms, and the intention of buying the Rheinland company is to get involved in large-caliber artillery, so even the machine gun is made bigger, which is completely inexperienced.

"Okay, I understand, Mr. President, there are two models on display this time, the first is an anti-aircraft gun, and the second is a heavy artillery." While explaining the two weapons, Horch did not forget to thank Eric for the suggestion, which was his sincere words, and the suggestion to make himself more likely to get the order was certainly appreciated.

"This..." As soon as Eric walked out of the stands, he saw an anti-aircraft gun not far away, FLAK41?

"This... That's what you call anti-aircraft guns? Eric was like seeing a ghost, because the 91mm caliber anti-aircraft gun in Horch's mouth turned out to be almost the same as the FLAK41 he was familiar with, of course, it was only the shape, and the ammunition feeder was different. Moreover, the load-bearing structure of the FLAK41 is also slightly different from that of the RM-91. The latter is significantly lighter and weighless.

The reason why RM-91 is not yet called FLAK-XX is because there is no official order to equip the troops after mass production, and there is no official military serial number, FLAK means anti-aircraft gun, such as 36, 41 are designed to produce years, RM-91 if it passes the test, and the Wehrmacht is willing to start procuring will have its own set of finalized methods. Starting with FLAK, it is a good way to distinguish by age, and if there is a variant, add letters at the end according to the military branch and purpose to distinguish it.

"Can we get started now?" Horch enjoyed the distraction in Eric's eyes, which he dismissed as a "design" stunning.
