The pilots of the major airlines took turns to sit in the cockpit of the M20, and each flew the M20 transport plane around the sky.

They were of course very happy with the results! Thanks to the torque conversion propellers, the power system is very efficient at all speeds and altitudes, and most importantly, it is very fuel-efficient and safe. One of the pilots tried to turn off the engine, but the M20 transport plane still managed to land several kilometers away, and it was forced to land on grass.

The pilot, who was flying the M20 transport plane's unpowered forced landing, gave a thumbs up and said, "Great! The maneuverability of this aircraft is just too good! I think I can drive it even with my eyes closed! ”

Another pilot chimed in: "That's true! The most wonderful thing is its torque conversion propeller, when the aircraft lands, it can also use the blades to generate negative tension to play the role of braking, and the gliding distance of the M20 transport aircraft after landing is much shorter than that of similar transport aircraft. It's a brilliant design! ”

Philip smiled and said to the pilot: "This representative is right! The advantage of torque converter propellers is that they can be adjusted to maintain maximum efficiency when the flight conditions change. When taking off, the small blade angle or distance, the load is small, the speed is high, and the maximum pulling force can be generated. When cruising, large blade angle or large distance, large load, low speed, can produce a large pulling force. By changing the blade angle to maintain the optimal blade angle of attack, high propeller efficiency and engine economy are obtained. ”

"In addition, what you just said is the anti-propeller function of this propeller, the anti-propeller manipulation propeller is that the blade angle changes to a negative value, so that the tensile force generated by the propeller changes direction and becomes a negative tensile force. Propeller manoeuvring is the placement of the propeller in the direction of the air flow of the flight. In flight, if an engine fails and fails, the propeller in the windmill state will not only not produce a pulling force, but will produce a large negative pulling force, that is, flight resistance, and have a serious adverse impact on the maneuverability of the aircraft. In order to prevent the occurrence of the above phenomenon, most constant-speed propellers on multi-engine aircraft are provided with shun-propellers. The propeller position is where the propeller generates the least drag, while also minimizing the engine speed. You can also return the oar after the oar. The so-called propeller return is to withdraw the propeller from the propeller position and return the propeller to the starting angle on the ground, that is, the minimum blade angle; Return the propeller in the air to the desired speed for starting. Its function is to enable a failed engine to be restarted after the fault has been rectified. Philip calmly explained the principle of the torque converter propeller thoroughly.

Representatives of these airline delegations gathered around to listen to his explanation, and it seemed that they were very interested in this kind of torque conversion propeller.

The Lufthansa pilot was surprised: "Oh, is this gentleman also a designer at Messerschmidt?" ”

At this time, Messerschmidt hurriedly said: "Delegates, this Mr. Philip is the designer of this torque conversion propeller. The torque conversion propeller of the M20 transport aircraft was provided by Mr. Philip's Dragon Soul Flying Manufacturing Company, and now Messerschmidt has formed a strategic partnership with Dragon Soul Aircraft Manufacturing Company, and in the future, Messerschmidt Company will cooperate with Dragon Soul Aircraft Manufacturing Company to develop aviation products. ”

As soon as the words ended, the delegates were in an uproar. A representative asked aloud: "May I ask Mr. Messerschmidt, how can this Dragon Soul Aircraft Manufacturing Company, which seems to be unknown, become a partner of Messerschmidt?" ”

Messerschmidt smiled: "It's really not well-known now, because the Dragon Soul Aircraft Manufacturing Company is just an aircraft manufacturing company that has just been established in Sweden, but I believe that in the near future, it will definitely be a blockbuster!" Now everyone has seen that the first product of Dragon Soul Aircraft Manufacturing Company, all-metal torque conversion propeller, and there is also a product under development, that is, aero engine exhaust gas turbocharger, which is also a product that can bring economic benefits to users! ”

One representative said with understanding: "These two products are indeed epoch-making, so can our existing aircraft be retrofitted with this kind of torque conversion propeller?" ”

Philip took the question and said loudly: "No problem! It is only necessary to install our torque converter controller in the fuselage through the aircraft factory, and the original fixed torque propeller can be replaced by the torque propeller produced by our company. Dragon Soul Aircraft Manufacturing Company can provide technical support to major aircraft manufacturers, as long as they agree that this is not a problem. ”

The representative thought for a moment and then asked, "It's just that this kind of modification costs a lot, right?" Whether it's cost-effective or not, we also need to know how much the retrofit will cost. I don't know how much this set of torque converter propellers sells? ”

Philip smiled: "Delegates, the price varies according to the size, but now I will only tell you one price range, which is between $500 and $3,000." ”

After listening to this, these representatives began to discuss, some said that the price was too expensive, not cost-effective at all, and some said that the replacement of the torque change propeller can still save a lot of fuel money, and besides, this kind of propeller can improve the performance of the aircraft, it is still worth it...... There are really different opinions, and there is no consensus.

Messerschmitt clapped his hands and said loudly: "Delegates, let's do it, we already have an intuitive understanding and experience of the M20 transport aircraft, now please go to the meal together, let's talk while eating!" ”

As soon as they heard that there was a good meal to enjoy, the delegates immediately nodded in agreement.

……

A few days later, Messerschmidt received orders for the M20 transport aircraft. Representatives of the airlines were satisfied and praised the M20 transport aircraft, especially its most prominent advantages: fuel economy and safety, which also made the owners and shareholders of the airlines very happy to accept it.

Messerschmitt watched the orders fly in one after another, and he was so happy that he couldn't close his mouth. Fortunately, he was not wrong, this Philip is simply the savior of the Messerschmitt company and the M20 transport aircraft, without him, the M20 transport aircraft may be buried in the dust of history. Now the order volume of the M20 transport aircraft has reached 60 in a few days, which is a very good result, and when the M20 becomes famous, I am afraid that the order volume will increase several times.

The success of the M20 has led airlines to ask aircraft manufacturers to replace existing transport aircraft propellers with torque conversion propellers, and to install such propellers in new aircraft delivered in the future.

This can give these aircraft manufacturers a headache, the torque propeller is too complicated, and only the Swedish Dragon Soul Aircraft Manufacturing Company can produce it, but its price is also very high, plus the modification of the old aircraft has to make more changes, although they all want to develop a set of torque propellers themselves, but obviously do not have this strength. As a result, aircraft manufacturers had no choice but to turn their attention to the Swedish Dragon Soul Aircraft Manufacturing Company.

The success of the torque propeller made the Dragon Soul Aircraft Manufacturing Company famous all of a sudden, and at the same time, the orders for the torque propeller began to rise by leaps and bounds, with orders reaching more than 1,000 sets in just one month, worth more than one million US dollars, which made the newly established Dragon Soul Aircraft Manufacturing Company immediately run at full capacity.
