- Chapter 4: Helicopter Components, Sections, and Systems › Main Rotor System › Rigid Rotor System
comprised of glass fiber reinforced material. The hub is a single piece of forged rigid titanium. The rigid rotor system is very responsive and is usually not susceptible to mast bumping like the semirigid systems because the rotor hubs ... fuselage to move together as one entity and eliminates much of the oscillation usually present in the other rotor systems. Other advantages of the rigid rotor include a reduction in the weight and drag of the rotor…
- 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 4: Helicopter Components, Sections, and Systems › Electrical Systems
Electrical Systems The electrical systems, in most helicopters, reflect the increased use of sophisticated avionics and other electrical accessories. [Figure 4-24] More and more operations in today’s flight environment are dependent on the aircraft’s electrical system; however ... helicopters can be safely flown without any electrical power in the event of an electrical malfunction or emergency. Helicopters have either a 14- or 28-volt, direct-current electrical system. On small, piston powered helicopters, electrical energy is supplied…
- Chapter 4: Helicopter Components, Sections, and Systems › Stability Augmentations Systems › Autopilot
Autopilot Helicopter autopilot systems are similar to stability augmentation systems, but they have additional features. An autopilot can actually fly the helicopter and perform certain functions selected by the pilot. These functions depend on the type of autopilot and systems ... installed in the helicopter. The most common functions are altitude and heading hold. Some more advanced systems include a vertical speed or indicated airspeed (IAS) hold mode, where a constant rate of climb/descent or IAS is maintained by the autopilot…
- Chapter 7: Aircraft Systems › Heating System › Exhaust Heating Systems
Exhaust Heating Systems Exhaust heating systems are the simplest type of aircraft heating system and are used on most light aircraft. Exhaust heating systems are used to route exhaust gases away from the engine and fuselage while reducing engine noise ... exhaust systems also serve as a heat source for the cabin and carburetor. The risks of operating an aircraft with a defective exhaust heating system include carbon monoxide poisoning, a decrease in engine performance, and an increased potential for fire…
- Chapter 10. Helicopter Operations › Section 1. Helicopter IFR Operations › 10-1-1. Helicopter Flight Control Systems
order to be certificated for IFR operation, a specific helicopter may require the use of one or more of these systems, in any combination. d. In many cases, helicopters are certificated for IFR operations with either one or two pilots ... Certain equipment is required to be installed and functional for two pilot operations, and typically, additional equipment is required for single pilot operation. These requirements are usually described in the limitations section of the Rotorcraft Flight Manual…
