- 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

- 9. TYPES OF APACHE Apache version Engine version Engine power AH-64A General Electric T700- 701 1,696 shp (1,265 kW) AH-64A+/D General Electric T700- 701C 1,890 shp (1,410 kW) AH-64E General Electric T700- 701D 1,994 shp (1,487 kW) WAH-64D Rolls-Royce Turbomeca RTM322 2,100 shp (1,600 kW)
- 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.
