1. HELICOPTERS
WHY HELICOPTERS?
OVERVIEW
CONTROLS

2.  Why Helicopters
1)VTOL(VERTICAL TAKE-OFF AND LANDING)
2)HOVER

3. TORQUE & ANTI-TORQUE
• Helicopters experience a torque about its C.G due to spinning rotor
• So in order to be stable anti-torque must be generated

4. Types of anti-torque techniques
1) Main rotor techniques
• Co-axial rotors Tandem rotors
• Side by side rotors Intermeshed rotors

5. 2)Tail rotor techniques
• Simple tail rotor Shrouded tail rotor
• Lateral thruster NOTOR ( No tail rotor )

6. Control mechanism of Helicopter
SWASHPALTES
PITCH CYCLIC
COLLECTIVE
A swashplate is a device that translates input via
the helicopter flight controls into motion of the
main rotor blades
Tilt the swash plate forward and aft(longitudinal cyclic),
varying the aircraft pitch,
Tilt the swash plate left and right (lateral cyclic),
varying the roll

8. Control on fuselage
To pilot hand
