Turbo-propellers; of a power exceeding 1100kW

HS v2022 Code: 841122

About turbo-propellers; of a power exceeding 1100kw

HS code 841122 covers turbo-propellers with a power exceeding 1100kW. These high-performance propulsion systems are essential components in large commercial and military aircraft, playing a crucial role in the global aviation industry. As air travel continues to grow, the demand for powerful and efficient turbo-propellers has become increasingly important, driving innovation and technological advancements in this specialized field.

Production process

The production of turbo-propellers under HS code 841122 involves a complex manufacturing process. It typically begins with the fabrication of the propeller blades, which are often made from advanced composite materials or high-strength alloys. These blades are then precisely engineered and balanced to ensure optimal aerodynamic performance. The propeller hub, which connects the blades to the engine, is also meticulously designed and constructed to withstand the immense forces and stresses encountered during operation. Finally, the entire assembly is rigorously tested and inspected to meet stringent safety and performance standards before being integrated into the aircraft.

Production inputs

The production of turbo-propellers under HS code 841122 requires a range of specialized inputs, including high-grade metals, composite materials, and advanced manufacturing equipment. Aerospace-grade aluminum alloys, titanium, and carbon fiber composites are commonly used in the fabrication of the propeller blades and hub. Additionally, precision CNC machines, specialized tooling, and advanced testing equipment are essential for the intricate manufacturing and quality control processes involved.

Production outputs

Turbo-propellers classified under HS code 841122 are primarily used as the main propulsion systems for large commercial and military aircraft, such as turboprop airplanes and transport planes. These powerful propellers are often paired with 841112 Turbo-jets; of a thrust exceeding 25kN or 841121 Turbo-propellers; of a power not exceeding 1100kW to provide the necessary thrust and power for these aircraft. The output of this industry is crucial for the global aviation sector, enabling the efficient and reliable transportation of passengers and cargo worldwide.
