Chapter Seventy-Six: The Blueprint for Jet Fighters
Philip nodded, "It fits its characteristics very well." When the jet engine starts, isn't it like the sound of wind and thunder? ”
Messerschmidt said excitedly: "By the way, Philip, how big do you think we should build a jet?" I guess it has to reach a speed of more than 500 km/h, right? ”
Philip thought for a moment, and then said indifferently: "What is the speed of the fastest plane at the moment?" Our jets must at least surpass it. ”
"The fastest current aircraft is no more than 300 kilometers per hour, so 500 kilometers is completely sufficient. ”
Philip looked at the overall engine plan, and then said, "Dr. Wiley, since that's the case, let's design a single-engine jet first to prepare for winning the championship at the aviation expo next year." It will surely shock the whole world when the time comes! ”
Philip has already thought of a design plan, that is, to design a jet trainer attack aircraft, in later generations there is a very famous trainer aircraft, that is, the K8 trainer, it is one of the largest number of aircraft exported by China, equipped with a TFE731-2A turbofan jet engine, thrust 16.01 kN. The thrust of this TFE731-2A turbofan jet engine is comparable to that of the ME15 turbojet engine, of course, there is no way to compare the thrust-to-weight ratio and fuel consumption, after all, it is a turbofan engine that has been ahead for I don't know how many years, and at this time the jet engine is not visible, and it is limited by materials and processes.
You must know that the TFE731-2A turbofan jet engine weighs only 350 kilograms, while the ME15 weighs 550 kilograms, a difference of nearly double. The K8 trainer is a type of primary trainer developed in cooperation with Pakistan in the nineties of the last century. The K in its name comes from the Karakoram Mountains on the border between China and Pakistan.
Using the K8 as a template for a design would have been a good choice, and even then, the world's first jet would have been considered a big one. The length of the K8 aircraft has reached 11.60 meters, the height is 4.21 meters, the wing area is 17.02 square meters, the empty weight has reached 2687 kg, the maximum fuel weight in the aircraft is 780 kg, the maximum external Daihol has reached 950 kg, the maximum take-off weight is more than 4 tons, the maximum level flight speed has reached 800 km / h, the maximum climb rate has reached 300 m / s, the practical ceiling: 13000 meters, the take-off run distance is 410 meters, and the landing run distance is 512 meters. The range reached 1,400 kilometers and the endurance was 4 hours and 25 minutes.
Philip had already drawn the blueprint for the jet plane in his mind, so he smiled and said to Messerschmidt: "Dr. Wiley, I have a rough estimate. Our jet aircraft can be designed as a trainer aircraft, and at the same time has a certain combat and ground attack performance, in fact, it can be regarded as a trainer attack aircraft, so it will not violate the restrictions of the Versailles Peace Treaty. Even with the installation of one ME15 engine, it will be much heavier than the current fighter. ”
Messerschmidt's face was full of joy and he said excitedly: "Okay, Philip, you can quickly paint your imaginary jet plane, I also want to see how strong it really is!" ”
Philip smiled and began to draw on paper, knowing that Philip was originally an expert in military design, drawing an airplane drawing was a piece of cake for him, and even drawing a 3D view by hand was not a problem.
Under Messerschmitt's watchful eye, it took Philip less than ten minutes to draw a jet trainer attack plane that looked very similar to the K8, and drew two bombs under the wings.
The more Messerschmidt looked at it, the more frightened he became, the shape of this plane was completely beyond his imagination, you must know that the planes at this time were almost all rear three-point landing gear, inverted seagull-style wings, like this kind of elliptical nose, blister cockpit, and the layout of the cockpit in the nose was the first time he had seen it.
Seeing Messerschmidt's surprised look, Philip also smiled: "Dr. Wiley, this is indeed a bit avant-garde, even a little offbeat, but the practical design is the most important thing." This jet trainer adopts a straight lower wing, air intake on both sides of the fuselage, a front three-point retractable landing gear, and a tandem blister cockpit, so that the two crew members have a very good view. The preliminary estimate is that the empty weight of the aircraft is about 3,000 kilograms, and the maximum take-off weight is about 4,500 kilograms. The length of the aircraft is about 11 meters, the height of the aircraft is about 4.2 meters, the wingspan is about 9.5 meters, the wing area is 20 square meters, the fuel weight in the aircraft is 1200 kg, the maximum external weight is 500 kg, the engine thrust is calculated at 1500 kg, and the thrust-to-weight ratio is about 0.3, which can make the maximum level flight speed of this aircraft reach more than 700 kilometers per hour, the endurance time is about 2 hours, and the range is 1200 kilometers. ”
When Messerschmitt heard these data, he could hardly believe his ears and said in surprise: "Really? Philip, that's great! I think that if this aircraft is really built, it will definitely make BFW and Dragon Soul Aircraft Manufacturing Company become the top aircraft manufacturers in the world! ”
Philip secretly said in his heart that Messerschmidt may not know that as soon as this jet trainer comes out, the BF109 fighter that made Messerschmidt famous, may not appear in this world. This may be a pity, but with jet engines, I believe that more aircraft than the BF109 will be born at Messerschmidt and Dragon Soul Aircraft Manufacturing. Historically, the design of the BF109 began a year or two later, but the appearance of Philip will definitely change the development of Messerschmidt.
Judging from the data, the BF109 is indeed a representative of a propeller fighter, which exerts the performance of the propeller aircraft to the extreme, and the best performance BF109G is equipped with a Daimler Benz DB605D engine with a power of 1850 horsepower. Its wingspan is 9.92 meters, the length is 9.07 meters, and the height is 2.5 meters. Empty weight 2630 kg. The maximum speed is 686 km/h, the ceiling is 10,000 meters, and the range is 700 kilometers. Armed with one MG10830 mm cannon, two MG13113 mm machine guns.
Statistically, the BF109 and Philip-designed jet trainers are inorganic, and the two are very close in size and weight, as well as in terms of maximum speed and ceiling. However, the jet trainer designed by Philip was much larger than the later BF109 propeller fighter in terms of fuel load, external weight, and take-off weight. And at this time, even Messerschmidt did not have a design plan for a high-speed fighter in mind.
Philip smiled: "Dr. Wiley, this trainer can also be used as an attack aircraft. With an external weight of 500 kilograms, it can carry bombs and auxiliary fuel tanks, and the range is sufficient. If it is equipped with the Vulcan cannon under development, it will be a powerful attack aircraft, and before the restrictions are fully relaxed, we can let it appear as a trainer aircraft and participate in aviation expos and aviation competitions, I believe it will definitely win the crown! ”
Messerschmidt laughed out loud with joy: "Philip, there you have it!" It seems that our two companies are about to take off! ”
