fixed propeller

These give ships better maneuverability than a fixed propeller and rudder system.

Pros and cons of folding compared with fixed propellers are:

A permanent-magnet electric motor moves a fixed propeller of a special design, that doesn't create cavitations at high speed.

He also attributed their sluggish steering under sail to interference with the flow of water to the rudder by the fixed propeller.

The fan, which is essentially a fixed propeller with many blades, is mounted in front of the core of the jet engine.

Z-Drive Propulsion- replaces conventional fixed propellers and rudders with two propulsion housings with the ability to rotate 360 degrees independently of one another.

Layout: Shaft drive through two ZF BW 800 HS 20 hydraulic gearboxes to LIPS fixed propellers.

Tyson turbines are a fixed propeller turbine designed to be immersed in a fast flowing river, either permanently anchored in the river bed, or attached to a boat or barge.

The fore and aft gondolas each housed a single engine driving a pair of swivelling propellors, one either side, while the centre car contained two engines with one fixed propeller each.

The CRP (Contra-Rotating Propeller) Azipod places a contra-rotating azipod propeller behind a fixed propeller achieving improved fuel efficiency.
