INTRODUCTION

The Apache AH Mk1 is an attack helicopter

produced by AgustaWestland under license

from Boeing, for the British Army. It is a

derivative of the AH-64D Apache helicopter,

which is used by the US Army. The AH Mk1

was custom built to meet the mission

specific requirements of the UK armed

forces.

DESIGN

The Apache AH Mk1 retains the same airframe design of the

standard AH-64D Apache, but with modifications to engines

and mission systems.

The major design changes include the integration of new

foldable rotor blades, weapon systems, countermeasures,

sensors and avionics equipment.

The crash-worthy fuselage was designed to withstand

12.7mm rounds.

It can even survive the hits of 23mm high-explosive

incendiary (HEI) rounds.

COCKPIT

The helicopter has an overall length of 17.5m, rotor

diameter of 14.6m and a height of 4.9m.

The maximum take-off weight of the AH Mk1 is

9,525kg.

The fully-integrated glass cockpit accommodates

two crew members in tandem configuration.

The digital "MANPRINT" cockpit integrates

coloured multifunction displays (MFD), pilot night

vision sensor (PNVS) and integrated helmet and

display sighting system (IHADSS).

AVIONICS

The avionics suite consists of integrated surveillance or

target acquisition equipment, including Longbow fire control

radar (FCR), TV, thermal imaging, direct view optics, laser

range finder / designator, laser spot tracker, automatic target

tracking and integrated GPS / INS / Doppler navigation

system.

The Longbow FCR allows the crew to find, track and engage

aerial and ground-based targets in all weather conditions.

The onboard communication systems provide the Apache

with command or attack co-ordination capabilities, through

real-time data sharing of weapon systems and mission

equipment.

ENGINES

The Apache AH Mk1 is powered by two Rolls Royce-Turbomeca RTM322 turboshaft engines.

Each engine develops a maximum take-off power of1,566kW.

The twin-shaft engine is controlled by a full authority digitalengine control (FADEC) system.

The helicopter has the fuel capacity of 1,421L. The cruisespeed of the Ah Mk1 is 259km/h.

The maximum range is 537km.

The helicopter has an endurance of two hours and 45minutes.
