Messerschmidt happily said, "Come on, come on!" Mr. Carr, let's patronize and discuss, let's dine first, let's talk while using! ”

Philip also chimed in: "Yes, this dish is almost cold!" And the intoxicating French red wine, my saliva is almost coming out! With that, Philippe opened a bottle of French Bordeaux wine and poured a glass for everyone.

Messerschmidt raised his glass and exclaimed, "Come!" After this glass of wine, I wish us a successful cooperation! ”

All four of them raised their goblets with a small half glass of red wine, touched each other, and then all fell on their backs.

After drinking this glass of wine, Philip sighed: "Alas, for more than a year, I feel like a dream!" If it weren't for the two of you, maybe I would have been a little engineer! ”

Karl waved his hand again and again: "Philip, you don't have to be presumptuous! In fact, the two of us are not like this, if it were not for Philip, how could our Bofors company have sprung up in the international arms market, let alone today's prosperity! ”

Messerschmitt also chimed in: "Yes, Mr. Karl is right! If Philip hadn't appeared, maybe our BFW company would have gone bankrupt! The M20 transport aircraft can be brought back to life, all thanks to Philip! And as soon as this thunder plan is successful, our three companies will become the world's ordnance giants, which makes people's blood boil when they think about it! ”

Philip poured a small glass of red wine for the crowd, then picked it up and said, "Come! For our bright future, let's have another drink! ”

After another glass of red wine, several people began to chat while eating.

Messerschmidt suddenly said: "We are now a community of destiny!" Philip, tell Mr. Karl about the development plan for turboprops! ”

Philip nodded and said, "Mr. Karl, our Wind Thunder plan includes development plans for jet engines, turboprop engines, and jet aircraft. This turboprop engine is derived from the jet engine, which can be said to be the serial development of the jet engine, and in the future, based on the ME15 jet engine, more advanced turbofan engines can also be developed, as well as more fuel-efficient turboprop engines, marine gas turbines and other products. ”

Karl asked curiously, "Oh, how can this jet engine be derived from so many products?" So what the hell is a turboprop engine? ”

Philip smiled: "Just now Mr. Karl has seen the overall design of the ME15 jet engine, and he must have a little understanding of the basic performance of the jet engine. The turbojet engine overcomes the main drawback of the piston engine plus the propeller, allowing the aircraft to fly faster, even breaking the speed of sound, and allowing the aircraft to fly higher. However, its biggest disadvantage is that the fuel consumption is too large, and its fuel consumption rate is estimated at the current level of technology, to reach more than 1 kilogram per kilogram hour, so it can generally only be used in fighter jets that pursue high speed, and can not be used in aircraft such as transport aircraft and passenger aircraft, because of its poor economy. So is there an aero engine that has more power than a piston engine and is close to the fuel consumption of a piston engine, the answer is yes, that is, a turboprop engine! ”

Karl asked curiously, "Oh, so how exactly does this turboprop combine the advantages of a jet engine and a piston engine?"

Philip smiled indifferently and said, "This starts with the principle of jet engines. The turbojet engine obtains huge thrust by exhausting high-temperature and high-pressure gas from the engine, and at the same time, a large amount of high-temperature gas that still has a certain amount of heat and kinetic energy is wasted, failing to maximize the heat energy generated by fuel combustion into effective power. As a result, its economy is poor, which is a weakness that restricts its continued development. There are three types of engines that can harness this gas energy, one is a turbofan engine, another is a turboprop engine, and another is a turboshaft engine. However, due to the limitations of technical conditions and materials, there is only one way that we can achieve at present, and that is the turboprop engine. ”

Philip paused for a moment, then continued: "The gas that flows out of the turbine of the jet engine, which still has a certain amount of energy, is sprayed from the tail nozzle at a speed of hundreds of meters per second to produce reaction thrust, which is a turbojet engine. If a set of turbines is installed behind the turbine, the gas expands in the back set of turbines, drives the turbine to rotate at high speed and emits a certain amount of power, and the front axle of this turbine passes through the original turbine and compressor rotor shaft, driving a fan with a larger diameter than the compressor, so that it becomes a turbofan engine, which is somewhat similar to the turbocharger installed on the piston engine. The gas coming out of the low-pressure turbine behind the temperature and pressure is greatly reduced, so the temperature and speed of the gas discharged from the tail nozzle of the turbofan engine are lower than that of the turbojet engine, of course, due to the low exhaust speed, the thrust is also smaller, but the air pressure flowing through the fan is increased, and the outer duct also produces a certain thrust, so the total thrust is still increased, and the fuel consumption is greatly reduced. However, due to the addition of a series of turbines and fans, the material requirements are higher and the processing technology requirements are very high, which is not yet possible. ”

Karl pouted and said, "Philip, you haven't gotten to the point yet. And what is the principle of a turboprop engine? ”

Philip laughed and said, "Mr. Karl, don't worry! I'm going to talk about turboprop engines right away. Add a set of low-pressure turbines behind the jet engine, the gas drives it to rotate at high speed and emits a certain amount of power, the front axle of the low-pressure turbine is empty over the rotor of the core engine, and the propeller is driven by the reducer in front of the compressor, so that most of the energy of the gas is converted into mechanical work, and the gas at the outlet of the turbine expands and accelerates in the tail nozzle and sprays out, and it can also produce a certain amount of thrust, so the economy of the turboprop engine is very good. Compared with piston engines, it has the advantages of light weight and low vibration, and with the increase of flight altitude, the performance is more superior, but the fuel consumption is about the same as that of piston engines. We plan to use the turboprop derived from the ME15 jet engine as the power of the M40 large transport aircraft, so that the M40 transport aircraft will be significantly ahead of other companies' transport aircraft in terms of technical performance. ”

Although Karl didn't seem to understand it, he also understood that this turboprop engine was a new type of aero engine that combined the advantages of a piston engine and a jet engine, and once it was successfully developed, it would definitely be a money-making machine. If this development continues, it is not known how much revenue this project will make in the future!

Carl slapped the table and said, "Good! Philip, I fully support this Wind and Thunder Project! It's better to sign a strategic cooperation agreement with the three of us, so that we can all become a strategic partnership! Through joint ventures and cooperation or other means, we use the advantages of capital, advanced technology and management experience to enhance the technological progress and core competitiveness of the three parties and the ability to expand the international market, we share competitive advantages and benefits, achieve long-term and strategic collaborative development relationship, promote resource complementarity, and achieve win-win cooperation. What do you think? ”
