  Chapter 6: Flight Controls › Flight Control Systems › Primary Flight Controls

  Flight Control Systems Flight Controls Aircraft flight control systems consist of primary and secondary systems. The ailerons, elevator (or stabilator), and rudder constitute the primary control system and are required to control an aircraft safely during flight. Wing flaps, leading ... edge devices, spoilers, and trim systems constitute the secondary control system and improve the performance characteristics of the airplane or relieve the pilot of excessive control forces. Primary Flight Controls Aircraft control systems are carefully designed to provide adequate responsiveness…

  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…

  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 4: Helicopter Components, Sections, and Systems › Hydraulics

  Hydraulics Most helicopters, other than smaller piston-powered helicopters, incorporate the use of hydraulic actuators to overcome high control forces. [Figure 4-25] A typical hydraulic system consists of actuators, also called servos, on each flight control, a pump which ... usually driven by the main rotor transmission and a reservoir to store the hydraulic fluid. Some helicopters have accumulators located on the pressure side of the hydraulic system. This allows for a continuous fluid pressure into the system. A switch…

  Chapter 10. Helicopter Operations Section 1. Helicopter IFR Operations 10-1-1. Helicopter Flight Control Systems a. The certification requirements for helicopters to operate under Instrument Flight Rules (IFR) are contained in 14 CFR part 27, Airworthiness Standards: Normal Category ... Rotorcraft, and 14 CFR part 29, Airworthiness Standards: Transport Category Rotorcraft. To meet these requirements, helicopter manufacturers usually utilize a set of stabilization and/or Automatic Flight Control Systems (AFCSs). b. Typically, these systems fall into the following categories: 1. Aerodynamic…
