ENABLING OBJECTIVES Draw and label a power required power available chart and a fuel flow versus airspeed chart. Identify maximum endurance loiter airspeed. Identify maximum rate of climb airspeed. Identify the best range airspeed and state the effects of wind components on best range airspeed. Define torque effect. State the means by which we counteract torque. State the means by which we control the helicopter about the vertical axis. State the means by which a multi-headed aircraft counteracts torque. State the effect the tail rotor will have on power available to the main rotor. State the two means by which tail rotor loading is reduced in forward flight. State one problem created by use of a tail rotor system to counteract torque. Define virtual axis mechanical axis and center of gravity. State the relationship between center of gravity mechanical axis and virtual axis. List the forces acting on the main rotor head. Define centrifugal and aerodynamic force. Define coning. Interpret how a vortex is formed and how it affects the efficiency of the rotor system. State the effect the main rotor vortices have on the tail rotor at low airspeeds. HELICOPTER POWERED FLIGHT ANALYSIS 3-1 CHAPTER 3 HELICOPTER AERODYNAMICS WORKBOOK Define ground effect by stating what causes it. State how ground effect affects power required. Define ground vortex and what causes it. Define translational lift by stating the phenomena which cause it. State how translational lift affects power required.
