High speed catamaran and multihull high speed marine vessel have
become very popular in the last two decades. The catamaran has
become the vessel of choice for the majority of high speed ferry
operators worldwide. There have been significant advances in
structural materials, and structural design has been combined with
higher power density and fuel efficient engines to deliver ferries
of increasing size. The multihull has proven itself to be a
suitable configuration for active power projection across oceans as
well as for coastal patrol and protection, operating at high speedd
for insertion or retrieval with a low energy capability. At present
there is no easily accessible material covering the combination of
hydrodynamics, aerodynamics, and design issues including
structures, powering and propulsion for these vehicles. Coverage in
High Speed Catamarans and Multihulls includes an introduction to
the history, evolution, and development of catamarans, followed by
a theoretical calculation of wave resistance in shallow and deep
water, as well as the drag components of the multihull. A
discussion of vessel concept design describing design
characteristics, empirical regression for determination of
principal dimensions in preliminary design, general arrangement,
and methods is also included. The book concludes with a discussion
of experimental future vehicles currently in development including
the small waterplane twin hull vessels, wave piercing catamarans,
planing catamarans, tunnel planing catamarans and other multihull
vessels.
High Performance Marine Vessels (HPMVs) range from the Fast Ferries
to the latest high speed Navy Craft, including competition power
boats and hydroplanes, hydrofoils, hovercraft, catamarans and other
multi-hull craft. "High Performance Marine Vessels" covers the main
concepts of HPMVs and discusses historical background, design
features, services that have been successful and not so successful,
and some sample data of the range of HPMVs to date. Included is a
comparison of all HPMVs craft and the differences between them and
descriptions of performance (hydrodynamics and aerodynamics).
Readers will find a comprehensive overview of the design,
development and building of HPMVs.
In the last half-century, high-speed water transportation has
developed rapidly. Novel high-performance marine vehicles, such as
the air cushion vehicle (ACV), surface effect ship (SES),
high-speed monohull craft (MHC), catamaran (CAT), hydrofoil craft
(HYC), wave-piercing craft (WPC) and small water area twin hull
craft (SWATH) have all developed as concepts, achieving varying
degrees of commercial and military success. Prototype ACV and SES
have achieved speeds of 100 knots in at calm con- tions; however,
the normal cruising speed for commercial operations has remained
around 35-50 knots. This is partly due to increased drag in an
average coastal s- way where such craft operate services and partly
due to limitations of the propulsion systems for such craft. Water
jets and water propellers face limitations due to c- itation at
high speed, for example. SWATH are designed for reduced motions in
a seaway, but the hull form is not a low drag form suitable for
high-speed operation. So that seems to lead to a problem - maintain
water contact and either water propulsion systems run out of power
or craft motions and speed loss are a problem in higher seastates.
The only way to higher speed would appear to be to disconnect
completely from the water surface. You, the reader, might respond
with a question about racing hydroplanes, which manage speeds of
above 200 kph. Yes, true, but the power-to-weight ratio is
extremely high on such racing machines and not economic if
translated into a useful commercial vessel.
This definitive text describes the theory and design both of Air
Cushion Vehicles (ACV) and Surface Effect Ships (SES). It begins by
introducing hovercraft types and their development and application
throughout the world in the last three decades, before going on to
discuss the theoretical aspects of ACV and SES craft covering their
hovering performance, dynamic trim over calm water, resistance,
stability, manoeuvrability, skirt configuration and analysis of
forces acting on the skirts, ACV and SES seakeeping, and the
methodology of scaling aerodynamic and hydrodynamic forces acting
on the ACV/SES from model test data.
The latter chapters describe a design methodology, including
design criteria and standard methods for estimating craft
performance, lift system design, skirt design, hull structure,
propulsion systems and power unit selection. Much technical
information, data, and references to further work on hovercraft and
SES design is provided. The book will be a useful reference to
engineers, technicians, teachers, students (both undergraduate and
postgraduate), operators etc. who are involved in ACV/SES research,
design, construction and operation.
Guides the reader on how to perform machinery and systems selection
within ACV and SES overall design
For teachers, students (both at under- and post-graduate level),
engineers and technicians involved in ACV/SES
