Pipistrel LN

The Pipistrel low-noise propeller is an adjustable fixed-pitch propeller for Ultralight and Experimental aircraft. The LN propeller may be used as both, push or pull-type propeller and therefore suits all aircraft construction types.

Pipistrel BAM

The Pipistrel BAM propeller is an adjustable fixed-pitch propeller for Ultralight and Experimental aircrafts. The BAM propeller may be used as both, push or pull-type propeller and therefore suits all aircraft construction types.

Pipistrel VARIO

The Pipistrel VARIO propeller is a variable-pitch propeller for Ultralight and Experimental aircraft. The VARIO propeller may be used as both, push or pull-type propeller and therefore suits all aircraft construction types.

Manufacturing method

The VARIO propeller’s outer skin and inside parts are made of composite materials, namely fibre-reinforced plastic. Blade’s base is made of aluminum and stainless steel tube, which lies within to ensure blade’s safe attachment to the propeller base (hub).
The propeller base (hub) is made of an aluminum alloy and features monolite construction. Inside, all parts are made of metal alloys. To achieve highest levels of propulsion efficiency combined with lower noise output, the manufacturer recommends a spinner to be mounted.
