Flap Rudders

Name: Flap Rudders
Brand: Neuver

Flap rudders producing more side force than classic rudders of equal size, in bulbous, medium and slim profiles for low to high speeds; for newbuild and retrofit, ice-class compliant.

Description

Neuver Flap Rudders produce more side force than a classic rudder of equivalent size. They can be used to reduce overall rudder area while keeping equal lift, or wherever high manoeuvrability is required. Rudders can be optimised for higher speeds, and the leading edge can be twisted to improve efficiency and cavitation characteristics. Suitable for newbuilds and retrofits.

Profiles

Flap Bulbous – low to medium speeds; extreme low-speed manoeuvring performance
Flap Medium – medium speeds; high manoeuvring performance and propulsive efficiency
Flap Slim – high speeds; high propulsion performance with a high-strength flap mechanism

Support types

Direct Trunk Support – no rudder size limitation, aft ship optimisation
Neck Bearing Support – robust, simple maintenance for vessels not needing direct trunk support
Heel Support – full spade benefits with enhanced stability; durable in ice and protects the propeller from foreign objects

Trunk configurations

Standard: basic design for hull integration
Standard with steering gear foundation: fits all KM steering gear
Extended: minimum installation time, optional fairwater and hull plating
