The Apache helicopter is designed for attack missions and can engage both ground and air targets. It has powerful engines, advanced sensors, and heavy armaments like Hellfire missiles. The pilot and gunner have helmet mounted displays for targeting. With its armor, sensors, and firepower, the Apache is a formidable weapon on the battlefield.

3. INTRODUCTION
 . It is essentially a flying tank- a helicopter designed to
survive heavy attack and inflict massive damage. It
can zero in on specific targets, day or night, even in
terrible weather. As you might expect, it is a terrifying
machine to ground forces.
 In this topic, we look at the Apache’s amazing flight
systems, engines, weapon systems, sensor systems and
armour systems. Individually these components are
remarkable pieces of technology.

5. WORKINGOF HELICOPTER
FOR STRAIGHT AND LEVEL FLIGHT
The following relationships must be true:
THRUST = DRAG
WEIGHT = LIFT.
Things which cannot be done by an aeroplane
 A helicopter can fly backwards.
 The entire aircraft can rotate in the air.
 A helicopter can hover motionless in the air.

7. APACHE HELICOPTER
 It is a attack helicopter an armed helicopter with the
primary role of an attack aircraft, with the capability of
engaging targets on the ground, such as
enemy infantry and armoured fighting vehicles. Due
to their heavy armament they are sometimes called
helicopter gunships.
 Weapons used on attack helicopters can
include autocannons, machine guns, rockets, and
guided anti-tank missiles such as the Hellfire

10. COCKPIT OF APACHE
The Apache has two cockpit sections: The pilot
sits in the rear and the gunner sits in the front.
The rear section is raised above the front section
so the pilot can see clearly.

11. HELMET MOUNTED DISPLAY
The Integrated Helmet and Display Sight System
(IHADSS)

12. APACHE SENSORS
The Longbow Apache detects surrounding ground
forces, aircraft and buildings using a radar
dome mounted to the mast. The radar dome uses
millimeter radio waves. that can make out the shape
of anything in range. The radar signal processor
compares these shapes to a database of tanks, trucks,
other aircraft and equipment to identify the general
class of each potential targets.

13. The pilot and the gunner both use night vision
sensors for night operations. The night vision sensors
work on the forward-looking infrared (FLIR) system,
which detects the infrared light released by heated
objects.

15. HELL FIRE MISSILE
 The Apache's chief function is to take out heavily
armored ground targets, such as tanks and bunkers. To
inflict this kind of damage, you need some heavy fire
power, and to do it from a helicopter, you need an
extremely sophisticated targeting system.
 Each missile is a miniature aircraft, complete with its
own guidance computer, steering control and
propulsion system

17. CONCLUSION
 Flying an Apache into battle is extremely
dangerous, to be sure, but with all its
weapons, armours and sensor equipment, it
is a formidable opponent to almost
everything else on the battlefield. It is a
deadly combination of strength, agility and
fire power.
