WELCOME TO THE SEMINAR
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 :
==> The four basic aerodynamic forces are Drag, Thrust, Weight and Lift.
Slide 5 :
For Straight And Level Flight
==> The following relationships must be true
THRUST = DRAG
WEIGHT = LIFT
==>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
