In flight variable pitch propellers

We design and make in-flight variable pitch propellers for Ultra Lights and UAV. Blades are in composite material and are made by the most advanced technology



Key features

•top of structural and functional reliability
•top performances
•extremely long operating life

Long life

TBO of the Hub is 2000 hours.
Blade life is depending from the composite material type and is specified by blades maker

Variety of blades

Wide variety of blade types available,made by highly qualified world famous Companies, in order to fill up the different pilot needs

Taylored solutions

Taylored solutions are developed for special applications

Why the In-flight variable pitch propeller?

To reduce the blade pitch to the geometrical value related to the aircraft instant speed, has the following effects:

  • The engine can supply all its full power

  • The blade section works closer to its highest yielding

  • The trust of the propeller increase strongly

It follows that take-off reduction can range from 30% to 60% of the original take-off by fixed pitch propeller

To reduce the blade pitch to the geometrical value related to the aircraft instant speed, has the following effects:

  • The engine can supply all its full power

  • The blade section works closer to its highest yielding

  • The trust of the propeller increase strongly

It follows that climb rate increase can range up to +80% of the original climb rate by fixed pitch propeller

In fixed pitch propeller or ground adjustable propeller we have a narrow window (aircraft speed / engine rpm) of good efficiency of the blade profile.
In variable pitch propeller, the pitch can be adjusted to high efficiency for all the flight condition envelope.
In other words, the in flight-variable pitch propeller replace to a set of propellers having different pitch and available each one at the right moment.
The fuel consumption is achieved as effect of the blade efficiency increase.
The fuel saving can range up to 25% for the same flight conditions.
For the flight school the propeller cost can be recovered in 2 years.

The take-off decrease and the climb rate increase available by the in-flight variable pitch propeller, reduce the time of the flight in most critical condition.
It follows the increase of the airworthiness condition
