33% better fuel consumption, same thrust? YES!
Please, be aware, the variomatic propeller is only suited for Vittorazi Moster plus 185cc.
The first in-flight adjustable propeller for paramotors.
In flight adjustable propellers have been around for a while, especially in fixed wing aircraft, but they have never successfully implemented in paramotors.
When We mentioned this idea to our propeller guy Dušan, at first he rejected it, because he believed that inflight adjustable systems are just too heavy, bulky, expensive, difficult to operate, slow to operate and they are not worth it.
We prove him wrong!
We succeeded to design a system that is lightweight, relatively cheap, easy to operate. It’s actually fully automatic, and it’s totally beneficial because it saves 33% of fuel.
Variomatic propeller have benefits of a ground adjustable propeller, without all the disadvantages. The principal is very simple:
Lower pitch = higher max RPM, more peak power- 10.1° over 6500 RPMQ
Higher pitch = lower max RPM more efficient at cruise- 13.1° until 6500 RPM
It’s fully automatic based on RPM/power on the propeller and the aerodinamical forces that act on propeller.
