Turbo-propellers; of a power not exceeding 1100kW

HS v2017 Code: 841121

About turbo-propellers; of a power not exceeding 1100kw

hs code 841121 covers the classification of turbo-propellers with a power output not exceeding 1100kW. This type of aircraft engine is a crucial component in the aviation industry, powering a wide range of smaller and medium-sized aircraft used for both commercial and military purposes. The global demand for these engines is driven by the continued growth in air travel, as well as the need for more fuel-efficient and environmentally-friendly propulsion systems.

Production process

The production of turbo-propellers classified under hs code 841121 involves a complex manufacturing process. Key steps include the fabrication of the turbine and compressor sections, the assembly of the gearbox and propeller shaft, and the final integration of all components. Advanced materials, precision engineering, and rigorous quality control measures are essential to ensure the reliability and performance of these engines.

Production inputs

The main inputs required for the production of 841121 turbo-propellers include high-strength alloys, such as titanium and nickel-based superalloys, for the turbine and compressor components. Specialized machinery, including CNC machining centers and welding equipment, are also crucial for the manufacturing process. Additionally, the industry relies on a skilled workforce of engineers, technicians, and assembly workers to design, build, and test these engines.

Production outputs

Turbo-propellers classified under hs code 841121 are primarily used to power smaller and medium-sized aircraft, such as regional airliners, turboprop commuter planes, and some military transport aircraft. The output of this industry is consumed by 880240 Airplanes and other aircraft, of an unladen weight exceeding 2,000 kg but not exceeding 15,000 kg, 880260 Airplanes and other aircraft, of an unladen weight exceeding 15,000 kg, and 880230 Airplanes and other aircraft, of an unladen weight not exceeding 2,000 kg.
