As one of the most deterrent weapons in the world today, the aircraft carrier is an indispensable national weapon of all major maritime powers. After years of painstaking development, China’s first domestic aircraft carrier has completed six sea trials, and it is expected that it will soon Can join our naval queue. At the beginning of the year, it was only after the completion of the revision of the Liaoning ship that had greatly improved its combat effectiveness. Last month, it completed the historic mission of the first team to approach Guam for ocean training. At about the same time, the first ship of the No. When I went to sea to test the flight, I will pay attention to when the 055 drive with the "aircraft carrier with the knife guard" will join our military aircraft carrier formation. We noticed that some military fans have proposed a situation on the two seas. How is the well-known problem I heard that the Liaoning ship started for ten hours, and the 055 drive only took a few minutes. Why? Even if the difference in displacement is a bit large, it is not so bad on the issue of starting up.

But the truth is, let the expert's analysis tell you where to go. The answer is actually very simple, because the power system of the Liaoning ship and the 055 drive are completely different. The Liaoning ship uses a steam turbine, and the 055 drive uses a gas turbine. Compared with the starting speed of Liaoning Ship and 055 frigate, it is essentially the performance comparison between steam turbine and gas turbine. The first thing to note is that it is not necessary to mix the steam turbine with the steam engine. The steam engine that pushes the piston to do work is not comparable to the steam turbine that pushes the turbine to do work. It is necessary to know that even for a nuclear-powered aircraft carrier, the power system can be used for a long time. A steam turbine that provides powerful output power.

xx数据显示辽宁船舶配备了四台TB-12蒸汽轮机。启动前的主要步骤是通过燃烧重油来燃烧锅炉中的重水,形成高温高压蒸汽。蒸汽促进了涡轮机的运转。托架螺旋桨通过驱动轴旋转,然后航空母舰可以航行。也就是说,重油烧成沸水再高温高压水蒸汽的时间是辽宁船的起始时间,热值大,储存阻力大,粘度高的重油最初点燃的难度很难点燃,因此从完全熄火状态到整个系统功率峰值需要至少10个小时。

至于配备055变频器的四台GT25000燃气轮机,最明显的优势是单机具有高功率和良好的启动加速性能。冷启动只需要大约两分钟。此外,燃气轮机具有高可用性和长寿命;音量和噪音。一些优点,如更小,但仅限于技术的复杂性,高燃料质量要求和极高的价格,尚未得到广泛应用,但随着技术的经济发展,这些问题逐渐得到解决,燃气轮机终于透露了夏普。
