Turbo-propellers; of a power exceeding 1100kW

HS v2017 Code: 841122

About turbo-propellers; of a power exceeding 1100kw

hs code 841122 covers the classification of turbo-propellers with a power exceeding 1100kW. These high-powered propulsion systems are a critical component in the aviation industry, powering large commercial and military aircraft. The global market for turbo-propellers is driven by the ongoing demand for efficient and reliable air transportation, particularly in emerging economies where air travel is experiencing rapid growth.

Production process

The production of turbo-propellers involves a complex manufacturing process. Key steps include the precision machining of turbine blades, the assembly of the propeller hub and reduction gearbox, and the integration of electronic control systems. Manufacturers utilize advanced materials, such as titanium and composite alloys, to optimize weight, strength, and durability. Rigorous testing and quality control measures are implemented to ensure the safety and performance of these critical aviation components.

Production inputs

The manufacture of hs code 841122 turbo-propellers requires a range of specialized inputs. Primary raw materials include high-grade metals, such as 810420 titanium and 720221 nickel-based superalloys, which are essential for the turbine blades and other structural components. Sophisticated machinery, including CNC machining centers and precision assembly equipment, is necessary to produce these complex propulsion systems. Additionally, advanced electronic components and software are integrated to manage the propeller's control systems.

Production outputs

Turbo-propellers classified under hs code 841122 are primarily used to power large commercial and military aircraft. These high-powered propulsion systems are typically found on turboprop-powered airplanes, such as regional airliners and military transport planes. The output of this industry is closely linked to the 880240 Airplanes and other aircraft, of an unladen weight exceeding 15,000 kg and 880260 Airplanes and other aircraft, of an unladen weight not exceeding 15,000 kg classifications, as these aircraft rely on the specialized turbo-propellers to achieve their desired performance and efficiency.
