  • Chapter 1: Introduction to the Helicopter › Controlling Flight › Throttle

    Throttle Helicopter rotors are designed to operate at a specific rpm. Figure 1-11. The throttle control mounted at the end of the collective control. The throttle controls the power produced by the engine, which is connected to the rotor ... maintain enough engine power to keep the rotor rpm within allowable limits to produce enough lift for flight. In single-engine helicopters, if so equipped, the throttle control is typically a twist grip mounted on the collective control…

  • Chapter 2: Aerodynamics of Flight › Hovering Flight

    Hovering Flight Hovering is the most challenging part of flying a helicopter. This is because a helicopter generates its own gusty air while in a hover, which acts against the fuselage and flight control surfaces. The end result is constant ... control inputs and corrections by the pilot to keep the helicopter where it is required to be. Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift…

  • Chapter 3: Helicopter Flight Controls

    fundamentals and theory and how they relate to flying a helicopter. This chapter also explained how aerodynamics affect helicopter flight and how important it is for pilots to understand aerodynamic principles and be prepared to react to these effects ... additional information on aerodynamics, refer to the aerodynamics of flight portion of the Pilot’s Handbook of Aeronautical Knowledge. Figure 2-48. Force vectors in vertical autorotation descent. Figure 2-49. Blade regions in forward autorotation descent. Chapter 3: Helicopter…

  • Chapter 6: Flight Controls

    addition, in some large and fast aircraft, controls are boosted by hydraulically or electrically actuated systems. In both the fly-by-wire and boosted controls, the feel of the control reaction is fed back to the pilot by simulated means ... Current research at the National Aeronautics and Space Administration (NASA) Dryden Flight Research Center involves Intelligent Flight Control Systems (IFCS). The goal of this project is to develop an adaptive neural network-based flight control system. Applied directly to flight…

  • Chapter 2: Aerodynamics of Flight › Sideward Flight

    Sideward Flight In sideward flight, the tip-path plane is tilted in the direction that flight is desired. This tilts the total lift-thrust vector sideward. In this case, the vertical or lift component is still straight up and weight ... horizontal or thrust component now acts sideward with drag acting to the opposite side. [Figure 2-42] Sideward flight can be a very unstable condition due to the parasitic drag of the fuselage combined with the lack of horizontal stabilizer…

  • Chapter 9: Basic Flight Maneuvers › Vertical Takeoff to a Hover › Technique

    Hover height, rate of ascent, and the rate of descent are controlled by using the collective. Helicopter position and the direction of travel are controlled by the cyclic. After receiving the proper clearance and ensuring that the area is clear ... obstacles and traffic, begin the maneuver with the collective in the down position and the cyclic in a neutral position, or slightly into the wind. Very slowly increase the collective until the helicopter becomes light on the skids or wheels…
