DUC Helices Propellers

DUC Helices Propellers designs, analyses, builds, certifies and maintains propellers, rotors and accessories for aircraft. The company was founded in 1997 in France. It combines aerodynamics with composite carbon materials. The company says its products are high performing, quiet and strong.

Its work covers the full life of a product. This includes design, analysis, manufacture, qualification, certification, industrialisation and maintenance. The company also applies its skills to projects in the space sector. It publishes service bulletins for owners, such as an increase in TBO for variable pitch propellers and a bolt replacement on four-blade variable pitch propellers.

The product range includes ground-adjustable pitch propellers and in-flight variable pitch propellers. It also makes helicopter rotors and drone rotors. Accessories include spacers, setting tools, governors and clothing.

A propeller selection tool on the website helps owners find the right propeller for their aircraft and engine. The list includes engines such as the Edge Performance EP912STi, Lycoming IO-320, O-235, O-320 and UL Power UL520T.

The company serves aircraft from airplanes to multicopters and helicopters. The selector lists many light aircraft and ultralight makers, including Jodel, Tecnam, Cessna, Robin and Zenith. The company says it works with aviation agencies such as EASA, the FAA, ANAC, CAAC and JCAB.

The company is ISO 9001 certified and says it is working toward EN 9100. It holds aeronautical approvals for design, production and maintenance. Its head office is at Beaujolais aerodrome (LFHV) in France. A US subsidiary in Sebring, Florida covers North, Central and South America.

More than ten approved installers in France fit its ground-adjustable and in-flight variable pitch propellers. Dozens of approved resellers work across Europe and worldwide, including South Africa, Eastern Europe, French overseas territories and South America. The company exhibits at AERO Friedrichshafen, France Air Expo, AERO South Africa, AERO Asia and the Paris Air Show.
