Chapter 4 Jet Aircraft Across Time and Space

  After a whole afternoon of explanation, Hughes finally understood what a jet plane was. A propeller-driven aircraft relies on the force generated by the rotation of the propeller to make the plane fly forward. However, when the speed of the propeller and the flight speed of the aircraft reach a certain level, it is impossible to make the plane go faster by simply increasing the propeller's rotational speed. On the other hand, the jet engine used in a jet plane uses the high-speed ejection of gas generated by fuel combustion to produce a reaction force that makes the plane fly forward, allowing it to obtain greater thrust and fly faster. Especially at high altitudes of 10,000-20,000 meters where the air is thinner, the jet engine has an unparalleled advantage over propeller-driven piston engines. Unexpectedly, as early as 1935, someone had already developed this type of engine, although it was still very immature. This means we can be the first to register a patent for a jet plane prototype, and now time is money.

  "Hughes, hurry up and take this engine blueprint to register for a patent. This is a great opportunity to make a fortune!"

  Hues looked puzzled and said to Sun Xiang: "Can this really work? I've heard what you said, but without testing it, how can I be sure that such an engine can propel the plane into the sky? ... Wait a minute, Steve, is that strange plane of yours using this engine?"

  Sun replied: "Yes, my friend, that's the kind of engine. I can definitely say that if it's made into an airplane, its speed can reach over 1,000 km per hour!"

  Hughes: "Oh my god, you know my H-1 only flies 560km? That's already the fastest in the world"

  Sun Xiang thought to himself: "It's better if you don't know that this plane can break the sound barrier, or it will scare your heart out. No, I have to do this step by step. If I disrupt the course of history, my future days won't be under my control anymore. Just thinking about such a life makes me feel uncomfortable."

  Hughs immediately called his driver Andor and had him take the drawings to apply for a patent.

  Sun Xiang said to Hughes, "This thing is related to the development of our future aviation company, please be careful and don't let the news leak out." "En" Hughes replied seriously.

  Sun Xiang, exhausted after asking Hughes to help him get a green card, fell into his first dreamland in this time and space. Hughes sighed softly when he saw the young man fall asleep: "Ah! Thanks for giving me so many surprises, you have the same momentum as I did when I was young, you'll be a great guy." What he didn't expect was that the flight he had been looking forward to would take place a whole year earlier than in history. Sun Xiang's appearance had already begun to slowly change the course of events for those around him. As this butterfly's wings grew larger and larger, would history still unfold as it did in the original world? This was something that no one could predict.

  The next morning, the two men began working in the laboratory with many technical experts to develop a jet engine. This new type of engine was an improvement on the old piston engine. After several days of hard work, the engine was initially completed, but this low-power machine could not be converted into a true jet engine yet, and there were still many technical difficulties to overcome, and it could not be taken to the battlefield in a short period of time. However, during the experiment, there was a disagreement on what kind of fuel to use for the engine;

  The working principle of a jet engine is different from that of a piston engine, and its combustion process is not intermittent.

  The fuel ignites and can burn until the engine runs out of oil. Therefore, it is not required that the fuel has good vaporization properties, and gasoline would be wasted. Not only that, but modern jet aircraft fly high and fast, which brings a big problem: when an airplane is flying at high altitude, the air is very thin, the atmospheric pressure is low, and the fuel is in a low-pressure state. In this environment, if gasoline is used as fuel, the gasoline in the oil tank and oil lines will immediately boil, producing a lot of oil vapor, blocking the oil lines and causing "vapor lock".

  The engine may also stall in mid-air due to lack of fuel, resulting in a serious flying accident. To prevent "fuel vapor lock", jet aircraft can only use kerosene with a very high boiling point and low volatility as fuel. In addition, the lubricity of kerosene is much better than that of gasoline, which will cause the lubrication performance of various engine parts to deteriorate, greatly shortening the service life of the engine, so this is another reason why jet aircraft burn kerosene.

  After Sun Xiang's persuasion, it was decided to use kerosene as fuel. In the design of the aircraft's shape, the original old-fashioned aircraft shape could not meet the needs of the new engine, which also required re-manufacturing. However, in a short period of time, jet aircraft still couldn't appear on the battlefield, and there were many technical defects. Therefore, Sun Xiang decided to bring historical aircraft onto the stage ahead of schedule. He chose the F4U Corsair, which was produced 40 years ago, but he had higher requirements for the new aircraft than in history. Two new engines were used as power sources. Due to the strengthening of power, the fuselage became lighter due to the weight of the engine, making it possible for the aircraft to withstand greater weight. Sun Xiang worked hard on the armor plating of the fuselage. The completed fuselage:

  Wingspan: 13 meters

  Length: 10.2 meters

  Output power: 2000 kilograms

  Speed: 700 km/h

  Armament: 6 x 12.7mm machine guns.

  Because the new model adopted the original pirate-type aircraft's appearance design, Sun Xiang decided to continue using the original name. As a counter to Japan's Zero fighter plane, with the use of an even more powerful piston engine, Fang Tou brought out historical data, and the Twin Wasp engine data from the Whitney company appeared in the Hughes Aircraft Institute, providing detailed information, studying all the way to having the aircraft take to the skies within 4 months.

  Haha, let Water Company's pirate plane make you appear on the battlefield ahead of time, Sun Xiang laughed loudly in his heart.
