Rolls-Royce
controllable pitch propellers
The Kamewa Type-A Controllable Pitch Propeller
Reliable, cost effective, and hydrodynamically efficient
the Type-A CPP builds on the success of the well-proven
XF-5 CPP design. Available in a range of sizes, covering
powers from 0.5-75MW, the Type-A CPP is suitable for
both naval and commercial applications, and has been
designed to meet current, and anticipated future CPP
market requirements.
The new Rolls-Royce Kamewa type-A hub is available in
over 40 hub sizes for 4 or 5 blades.
Key features of the type-A CPP
- 20% improvement in power-to-weight
ratio
- Robust design for increased service-life
- Available in NiAl bronze or stainless
steel
- Open water, nozzle and ice-class options
- 4 or 5 bladed options
- Increased bearing surfaces for improved
strength and wear resistance
- Optional features include, underwater
replacement of blades and a fully feathered design
Offered in two options depending on the speed of the
vessel, the standard CP-A hub covers speeds up to 30knots,
with the CP-A/H hub designed for faster vessels. Service-life
has been extended through significant design improvements.
Using computational fluid dynamics and advanced tooling
techniques, the hub shape has been specifically developed
to reduce drag, giving further benefits in propulsive
performance.

Improved power pack for the Type-A CPP
The introduction of a new power pack incorporating load
sensing hydraulic pumps, substantially reduces the amount
of power required to operate the system, and the amount
of oil in circulation. Offered are three types of oil
distribution (OD) box, providing increased pitch setting
accuracy and simplified service. In the first system
the OD box is situated on the propeller shaft. In the
second system, the OD is mounted at the forward end
of the gearbox, and in the third option, the oil distribution
system is integrated into the gearbox housing.
Type-A CPP Control system
Based on the Rolls-Royce common control platform, the
new control system for the CP-A comprises a bus connection
between the pitch setting system and the bridge levers
and displays. Enhanced touch screens at the bridge station
provide the operator with a clear and unobstructed view
of the system status. The propeller controls are based
on latest Rolls-Royce human/machine interface developments,
with the system being easily integrated with other Rolls-Royce
propulsion equipment, DP systems, and proprietary equipment.
