The main components of an aircraft, the organism, landing gear, power plant, flight control system, on-board equipment, and other systems. Combat aircraft also have airborne ** systems. The airframe includes wings, fuselage, and tail.
The function of the wing is to generate lift when moving in the atmosphere, and it is also equipped with ailerons and spoilers; Aircraft without a tail are equipped with longitudinal control devices (lifting ailerons) on the wings, in addition, there are lifting devices on the wings. The fuselage is used to house personnel, load equipment, cargo, **, power plant and fuel, etc. The wings and tail are fixed to the fuselage, and the landing gear struts of some aircraft are also fixed to the fuselage.
The tail is divided into a horizontal tail and a vertical tail. The horizontal tail is generally composed of a horizontal stabilizer and an elevator, and the vertical tail is composed of a vertical stabilizer and a rudder. Some aircraft make the horizontal tail into a whole, which can be manipulated and deflection, which is called a full-motion flat tail.
Some aircraft do not have a horizontal tail and are equipped with horizontal winglets in front of the wing, known as front wings or canards. The horizontal tail ensures the pitch stability, maneuverability and balance of the aircraft. The vertical tail ensures the directional stability and maneuverability of the aircraft, and together with the wings, ailerons or spoilers or differential flat tails, the lateral stability and maneuverability of the aircraft are guaranteed.
Landing gear] is used to support the aircraft during take-off, landing, parking on the ground (water) and taxiing. It includes landing gear, wing lifters, take-off acceleration devices, landing deceleration devices, and some aircraft also have arresting hooks. The landing gear can generally be retracted when the aircraft is flying, and the landing gear of some older aircraft and low-speed aircraft cannot be retracted.
There are wheeled, pontoon, hull, skid and other types of landing gear. 【Power Plant】 A general term for aero engines and various devices and systems that ensure the operation of engines. These include propulsion systems, starting systems, control systems, fuel systems, lubricating oil systems, as well as engine fixtures, thrust direction control systems, and fire extinguishing equipment.
The most commonly used engines for modern aircraft are gas turbine engines, including turbojets, turbofan engines, turboprop engines, and propeller fan engines. Piston engines are used only in light aircraft, and rocket engines are used on test aircraft and accelerators. 【Flight Control System】 It is used to transmit control instructions, drive rudder surfaces and other mechanisms to control flight attitude, and is divided into main control system and auxiliary control system.
The former is used to control the flight trajectory, including the steering stick (disc), pedals, rudder, transmission device connecting the elevator (or full-motion flat tail) and ailerons, and other specialized devices. The latter includes adjustment tabs, flaps, airbrakes, adjustable stabilizers, and control mechanisms for wing variable sweep angles. According to the different control instructions, the aircraft flight control system can be divided into the aircraft artificial flight control system and the 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. Military aircraft are also equipped with special equipment such as electronic countermeasures. The system of combat aircraft includes ammunition, fire control system, loading and launching devices, etc.

Simply from a fluid mechanics point of view! The pressure on the lower surface of the wing of the aircraft is greater than the pressure on the upper surface, which makes it possible for the plane to go upward, and with the forward vector, it flies!

To put it simply, the flight of paper airplanes is formed by the interaction of two forces, gravity and lift. The weight of the paper airplane itself pulls the fuselage downward, and the wings grab the air, causing the paper airplane to float in the air. The two forces of one up and down, plus the power of the thrower to help the paper airplane glide forward - produce inertial motion and slide out of the trend, the balance of the three forces can fly a beautiful attitude.
How do real airplanes fly?
Gravity refers to gravity, thrust refers to the thrust of the airflow generated by the turbine of the aircraft, and drag refers to the force of air affecting the flight of the aircraft. Therefore, when the thrust and lift generated by the turbines of the aircraft are greater than the gravitational force and drag of the earth, the aircraft will naturally soar in the sky!
Flight encyclopedia, please see the reference**:
Airplanes are heavier-than-air aircraft, so they need to expend their own power to gain lift. And the ** of lift is the effect of air on the wing in flight. The upper surface of the wing is curved and the lower surface is flat, so when the wing is in relative motion to the air, the air flowing through the upper surface travels a distance (s1) in the same time (t) than the air flowing through the lower surface (s2), so the relative velocity of the air on the upper surface is faster than the air on the lower surface (v1 = s1 t> v2 = s2 t1). >>>More
Two people squat, walking in the opposite direction, overlapping, probably squatting down and leaning on the waist of the other. It's very important here (success or failure depends on whether this overlap is good or not) After completing the above actions, it depends on the tacit understanding between the two, just press ctrl very rhythmically... Remember to wait for others to press (don't just look at yourself) and so on ... >>>More

It has been six years since the sudden disappearance of Malaysia Airlines MH370, and the days and nights of the six years have been torturous for the families of the missing. And Malaysia Airlines has also become a mystery in the hearts of the world. Why can't you find a passenger plane in such an era full of satellites?
Dual-aisle aircraft is a wide-body passenger aircraft, a passenger aircraft with a body width greater than 4m, and the seats inside the cabin are divided into three areas: left, middle and right, and there are two aisles in the double-aisle. >>>More
