"You cannot deny that although the Armistice Treaty has restrictions on your country, we really do our best to take care of your country's face and interests. We are much more kind to your country than Britain, Russia and Belgium! In this world, only we have shown goodwill to your country. So from the reality, is the hatred between the two countries important?"

"I believe you also know that the Kingdom of Bavaria has opened its own automobile market to France. This is a kind-hearted move, and even the French government has expressed support and appreciation. So is it necessary for you to worry about the previous hatred? And this time, I came to France to conduct technology and trade exchanges. Can we not talk about politics but only technology and trade?"

Henkel said that at the end of the conversation, Henkel could feel that Marcel's hostility was very small. As Henkel said, even though the French government and citizens still had grudges against Germany in their hearts, the future environment will force them to make the right choice. If France wants to maintain its status and economic interests, it must move closer to Germany and Austria. As time goes by, the hostility between each other will be diluted by the interests in reality.

"Well, as a customer, especially the one who came to Toulouse from Bavaria so quickly, even for this point, we should have a technical discussion. If you have anything to ask, I can try my best to answer it," said Marcel.

"Okay, the first question is, when you designed this aircraft, you equipped it with three machine guns, two of which were arranged on the lower part of the engine, and the other one was deployed on the side of the engine. So I wonder why you didn't install 132 machine guns in the main shaft of the engine? In this way, the drag on the front of the aircraft can be reduced, and the fire trajectory will be better. According to your previous arrangement, the landing point of the bullet will tend toward the side of the aircraft. This is a bad feeling." Henkel said.

"Because I don't like the layout of shaft guns, although in actual combat, the shaft guns of your j6 fighter and the two machine guns arranged on the upper part of the inverted V-type engine have very good performance, but I think this deviates from the design principle of aircraft aerodynamics." Marcel thought for a while and said.

"I don't understand what it means." Henkel said with a frown.

"According to the distance from fluid mechanics, we need to make the appearance of the aircraft as smooth as possible, and various protrusions should be as few as possible. Your country's later-stage aircraft is equipped with superchargers. Because of the shaft gun, your country places the supercharger on one side of the aircraft, but this will inevitably increase the windward area of ​​the aircraft head. Therefore, if I designed the aircraft, I would cancel the shaft gun of the engine and then install the supercharger behind the engine." Marcel thought for a while and said.

(In fact, there are advantages and disadvantages to the arrangement of weapons of shaft cannons. In terms of firepower, the firepower landing point formed by shaft cannons and wing cannons is the best. However, because the precious position at the rear of the engine is occupied by the cannons, the supercharger can only be mounted on one side of the engine. If it is a small mechanical supercharger, it is okay, but if it is a two-stage supercharger, it cannot be arranged because the two-stage supercharger is too large. Generally, the two-stage supercharger is arranged at the rear of the engine. Moreover, the author feels that the heat and vibration generated when the cannon is fired are not good news for the engine.)

"Your idea makes sense. In fact, someone has asked me this question before, but unfortunately, war focuses on reality rather than ideals. In some cases, it is acceptable as a compromise. If you don't accept it, then the problem must be solved. For example, I want to equip two 20 machine guns and two 127 machine guns on a future fighter. So if it were you, how should the firepower be arranged?" Henkel asked.

"This question is very good. In fact, putting weapons into the nose is already very good. Early British and French fighters just put machine guns outside the nose, or even on the upper wings." Marcel said. "And I have solutions in this case, too." As he said that, Marcel took Henkel to a corner of the delivery room, and a huge canvas cover something.

"I think modern aircraft design requires a change. The wings made of biplane and several wooden boards have developed to the limit. Both strength and aerodynamic performance are difficult to improve. The strength of the wings made of wood is limited. If the dual-wing mode is adopted, the support must be needed in the middle. These cables and brackets undoubtedly increase the resistance of the aircraft. So, I have been studying the use of a brand new single-wing mode to replace the biplane mode." Marcel said as he walked over and pulled away the canvas. Then a huge thing similar to the later wing box appeared in front of Henkel.

"To put it simply, I will change the current wooden wing into a box, a carefully designed wing box made of metal. You just asked me where the weapon is installed. It's very simple. Just put it in this box. This can greatly enhance the strength of the wing, reduce drag, increase lift, and be more suitable for high-speed flight. Of course, doing so also increases the space that the aircraft can use." Marcel said.

"In addition to loading machine guns and ammunition here, we can also install fuel tanks." Marcel then came to the other side and took out a soft fuel tank made of rubber and said.

"You just want to install this soft fuel tank directly into it? Then fix it with a bracket?" Henkel asked.

"Of course not. We also need a pressurized device to ensure that the fuel in the fuel tank can still enter the oil pipeline when the aircraft is maneuvering." Marcel said.

"That's over?" Henkel asked.

"That's all." Marcel didn't think he had any omissions.

"It's a good idea, but I want to say, you must have not conducted any related experiments, right?" Henkel said with a smile.

"I don't understand what you mean. Is there something wrong with my idea?" Marcel asked.

"Your idea is very good, but unfortunately, your current ability cannot perfect this concept at all, because there are many details and precautions that will only be exposed in experiments. For example, the soft fuel tank you just mentioned cannot be installed so simply during test flights, because when the plane is flying, the soft fuel tank will collide and rub against the bracket inside the wing, and you obviously didn't think of how to solve this problem. So, I concluded that you just had an idea, but definitely did not do actual experiments." Henkel said with a smile.
