What systems are airplanes generally divided into

1. Aircraft generally include wings, fuselages, tails, engines and landing gears.

2. The main components of conventional aircraft are fuselage, wing, tail, landing gear, power system, flight control system, avionics system and on-board equipment, etc. The wing is the main part that generates lift. The aidels for lateral control and flaps used to increase lift are also installed on the wings.

3. There are electrical system, flight control system, instrument display system, VHF communication system, VHF navigation system,Inertial navigation system, hydraulic system, fire detection and fire extinguishing system, warning system, oxygen system, air conditioning and supercharging system, engine and wing anti-icing system, landing gear system, lighting system and fuel system, etc.

4. Wings are the main parts used to generate lift in aircraft, which are generally divided into left and right wings. Wings usually include straight wings, rear-swing wings, triangular wings, etc.

5. According to the different sources of control instructions, the aircraft flight control system can be divided into aircraft manual flight control system and aircraft automatic flight control system. Airborne equipment includes driving navigation instruments, engine instruments, radio communication equipment, radar, electrical equipment, environmental control and life support equipment.

what Is it the aircraft automatic driving system

1. The automatic driving system (autopilot) is a device that automatically controls the aircraft to complete the three-axis action by the pilot pressing some buttons and rotating some knobs, or receiving ground navigation signals by the navigation device. The autopilots equipped with different models of aircraft may have some minor differences, but they are generally similar.

2. Professional introduction of flight attendants: The automatic driving system is a kind of equipment operated by pilots.Set, or the navigation device receives the ground navigation signal to automatically control the aircraft to complete the three-axis action. The autopilots equipped with different models of aircraft may have some minor differences, but they are generally similar.

3. The automatic flight system mainly includes subsystems such as (autopilot flight guide automatic throttle). The flight control of the aircraft is divided into manual control and automatic control. Manual control refers to the pilot's control of the rudder and trottle lever through the mechanical control system on board to control the flight of the aircraft.

4. The aircraft autopilot system is a complex closed-loop system. The autopilot sends a signal to control the deflection of the rudder and generate the rudder control moment, so as to realize the manipulation of the aircraft. Then the aircraft changes the flight attitude and changes the output signal of the autopilot through the measurement device, so as to Compound action, and finally reach balance.

5. It can be driven. Nowadays, new aircraft have automatic driving systems. For example, the Boeing 737 series aircraft is equipped with an advanced digital flight control system. When it reaches an altitude of 400 feet after take-off to landing, the whole flight process can be self-driving, and the aircraft will automatically select the best flight route.

6. Why can airplanes be autonomous? Chapter 1 Modern aircraft are often equipped with automatic driving systems, so that the on-board computer can control the automatic flight of the aircraft when the situation permits, so that the pilot will not be too tired. As early as decades ago, people invented autopilots.

What are the systems of helicopters?

The CCPM system of the helicopter is ** differential pitch hybridControl structure**, which is used to combine Cyclic and collective control signals into a single control signal to control the helicopter.

Helicopters are mainly composed of fuselage and lift (including rotors and tail blades), power, transmission and airborne flight equipment. Rotor wings are generally driven by turbine shaft engines or piston engines through a mechanical transmission system composed of transmission shafts and reducers, etc., and can also be driven by the reaction force generated by the paddle tip jet.

The control system of a helicopter is different from that of a fixed-wing aircraft. It usually consists of the following parts: the total distance joystick, abbreviated as the total distance lever, is used to control the change of the total distance of the rotor blade blades. The total distance joystick is generally placed on the left side of the driver's seat and rotates around the support axis and down.

stightThe information of the upgrade aircraft is introduced as follows: the power source, the helicopter is mainly composed of the fuselage and the three major systems of lift, power, transmission and on-board flight equipment.

Special lighting system: It is composed of special lighting for helicopters, which is mainly used to improve the visibility and controllability of helicopters in emergency situations. Common special lighting systems include emergency lights, search lights and floor lights.
