How to choose correct HS code in ASEAN

Co-engine (heavy: co-pilot engine becomes a flying weapon!) With the continuous development of aviation technology,How to choose correct HS code in ASEAN the design of aircraft is also constantly improving and upgrading. From the original single-engine aircraft to the current twin-engine and multi-engine aircraft, the development direction of aircraft engines has always been safe and efficient. Among many models, twin-engine aircraft undoubtedly have a greater advantage. In twin-engine aircraft, the auxiliary engine can be said to be a heavy flying weapon. This article will introduce in detail the characteristics and advantages of the auxiliary engine and its application in flight. First of all, let's understand what a secondary engine is.The secondary engine refers to the backup engine that can quickly replenish the power of the aircraft in the event of the loss of the main engine. Common secondary engines include gas turbine engines, propeller engines, etc. In some special models, such as military aircraft or low-altitude split-wing models, secondary engines are often the main source of power. Compared with the main engine, the secondary engine has some unique advantages in design. First of all, the secondary engine adopts a lightweight design, which is more compact than the main engine, so it can be installed on the aircraft more conveniently and flexibly. Secondly, the auxiliary engine can be paired with the main engine, so that the whole power system can switch between each other more flexibly in case of failure. Finally, the secondary engine can play an important supplementary role when a large amount of power output is required. In actual flight operations, the auxiliary engine also has a very important application value.First of all, the existence of auxiliary engines can significantly improve flight safety. In the event of the failure of the main engine, the secondary engine can provide key supplementary power for the aircraft, ensuring that the pilot can control the flight direction and altitude of the aircraft in time. At the same time, the start-up speed of the auxiliary engine is also relatively fast, which can quickly replenish power in a short time to avoid risks in emergencies. Secondly, during long-term navigation, the auxiliary engine can also play a role in saving energy. In some high-altitude flights near the limit, the half-power output mode of the auxiliary engine can be used to achieve the purpose of sustainable fuel conservation. Of course, there are also some challenges in the sub-engine. How to improve the control, decision-making and pilot training of multi-engine aircraft, and how to maximize the potential of sub-engines, requires the daily practice and optimization of aviation manufacturing enterprises and pilot teams.In summary, the application of auxiliary engines in twin-engine aircraft has become more and more common. It has great advantages in flight safety, energy saving and environmental protection. In the future, we can expect more innovations and breakthroughs, so that the auxiliary engine can be used more widely and deeply in the scope of application of aircraft.
