HELIX CARBON GMBH
The company HELIX Carbon GmbH develops and manufactures carbon fiber propellers since 1990 for a wide range of applications. Starting with a staff of three people propellers were developed for the paramotor and paramotor trike market. Today, Helix has 10 employees working on our 1000sqm facility at the Merzbrück airfield producing an average annual volume of 11,500 propeller blades for the paramotoring and ultralight market in general.
WHY A CARBON FIBER PROPELLER?
Propellers made of carbon (carbon fiber reinforced plastic – CRC) have a long lifespan and can be repaired very well. By using the same mold, the blades are identical and reproducible, thus offering a high dimensional stability. Carbon fiber propellers do not react to moisture. So they not warp and also give a high dimensional stability. With better strength properties the carbon fiber propellers have high vibration compensation. The vibration of the engine is better absorbed and thus gives a smoother running.
The production of the propeller blades is handmade. The aluminum molds are first coated with a viscous, especially high- quality epoxy resin. This is about a 0.3 mm thick layering that later forms the propeller blade surface. This is particularly robust and has a high surface quality.It follows a thin liquid epoxy resin, in which the previously suitably tailored carbon fiber fabric layers are embedded. The mold halves are folded together and after four hours of curing at 65 ° C, a complete propeller blade is removed.
The edges are removed and the surface is polished. The blades are weighted, and balanced accordingly. The last step before final inspection is the CNC milling of the propeller bolt holes.
Helix propellers are organized by number of blades, diameter, paramotor/engine model and reduction ratio. If you don’t find your particular model or you have a doubt please contact us. We will find the right propeller for your paramotor or trike. An example: H30F 1.25m R-M-07-02
