Slide 1 :



Apache Helicopter

Slide 2 :


==> The Apache Helicopter is a revolutionary development in the history of war.

==> 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.

==> Individually these components are remarkable pieces of technology

Slide 3 :


==> The first series of Apaches, developed by Hughes Helicopters in the 1970s, went into active service in 1985.

==> The U.S military is gradually replacing this original design, known as the AH-64A Apache, with the more advanced AH-64D Apache Longbow.

==> In 1984, Mc Donnell Douglas purchased Hughes Helicopters, and in 1997, Boeing manufactures Apache helicopters

Slide 4 :

Aerodynamic Forces

==> The four basic aerodynamic forces are Drag, Thrust, Weight and Lift.

Slide 5 :

For Straight And Level Flight

==> The following relationships must be true


==>If for any reason, the amount of drag becomes larger then the amount of thrust, the plane will slow down.

==>If the thrust is increased so that it is greater than drag, the plane will speed up .

==>By increasing the lift, the pilot can make the airplane climb.

Slide 6 :

Working Of A Helicopter

==> The helicopter can do three things that an airplane cannot

==> A helicopter can fly backwards.

==> The entire aircraft can rotate in the air.

==> A helicopter can hover motionless in the air

==> The rotating wings of a helicopter are shaped just like the airfoils of an airplane wing,

==> The helicopter’s rotating wing assembly is normally called the Main Rotor

Slide 7 :


==> In order to spin the shaft with enough force to lift the vehicle, engine of great power is required.

==> Reciprocating gasoline engines and gas turbine engines are the most common types

==>The arrangement works really well until the moment the vehicle leaves the ground

Slide 8 :

Controls And Sensors

==> The Apache cockpit is divided into two sections, one directly behind the other.

==> The pilot sits in the rear section, and the co-pilot/gunner sits in the front section.

==> The pilot maneuvers the helicopter and the gunner aims and fires the weapons.

==> Both sections of the cockpit include flight and firing controls in case one pilot needs to take over full operation=

Slide 9 :

Evasion And Armour

==> The Apache's first line of defense against attack is keeping out of range.

==> The helicopter is specifically designed to fly low to the ground, hiding behind cover whenever possible.

==> The Apache is also designed to evade enemy radar scanning. If the pilots pick up radar signals with the onboard scanner, they can activate radar jammer to confuse the enemy

==> The Apache is also designed to evade heat-seeking missiles by reducing its infrared signature.

Slide 10 :


==> 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

==> The U.S is now developing a new revolutionary helicopter called ‘COMANCHE’, which has several superior techniques.

==> But it is still under construction. So, at present the APACHE holds the no.1 position among the revolutionary helicopters
