What is the process of making a real modern aircraft???

First of all, it should develop data on the aircraft of its own hostile countries that it can confront it; Secondly, on the basis of these data, a design drawing of the aircraft was drawn on the drawings. Immediately after that, the aircraft on the drawing is made into an airplane model, and the wind tunnel test is done in a place called a wind tunnel to imitate the environment of the airplane flying in the air, etc., and the unreasonable plans are eliminated one by one, and the practical ones are repeatedly improved and "promoted". Immediately after that, the real aircraft was built according to the model, which was the prototype, and this entered the test flight stage.

Different prototypes, equipped with different avionics equipment, etc., or uninterrupted test flights, weak and strong (only, test flights are much more dangerous than wind tunnels, prototypes are aircraft that have not undergone any technical verification, the failure rate is very high, which requires excellent test pilots, plane crashes are absolutely common), and then, the most reasonable aircraft was left behind, and it entered the final first flight stage, after the army took a fancy to the aircraft, after approving the order to the Ministry of Defense, the aircraft was mass-produced and equipped with troops, Immediately after that, he entered service. In view of the shortcomings of the aircraft, the aircraft design bureau should also make various improvements in the aircraft, so that the service of the new model will not last so long.

Take the passenger aircraft as an example Place an order and schedule Cast the main structural parts, and supply the main structural parts to the branch suppliers The fuselage **, girders, ribs, and skin are in place The middle section of the fuselage and the wing are connected The fuselage is connected before and after the front and rear installation of ailerons, flaps, tails, landing gear, etc., the laying of lines and pipelines in the aircraft, and the installation of electrical equipment is on the line.

How are modern foreign aircraft made? Long insight.

First of all, the materials are different, and now the aircraft are made of high-temperature-resistant and high-pressure resistant materials.

Then there are different control methods, modern aircraft with hydraulic, electrical control, advanced computer analysis and control, and its safety measures are more complete.

Modern aircraft use a double vertical tail, which increases maneuverability.

Adjustment tabs. Increased stability.

Aircraft development is a process that combines invention and creation.

On December 17, 1903, Orville Wright piloted a self-made aircraft named "Asuka" by the brothers successfully flew a test flight, opening up a new era in human aviation.

The first test flight flew 120 feet (36 58 meters) off the ground for 12 seconds, achieving the first sustained, powered, and maneuverable manned flight of mankind, and the Wright brothers became recognized as the inventors of the aircraft by countries around the world.

1. The main task of the fighter is to engage in air combat with the enemy fighter plane and seize air superiority (air supremacy). The second is to intercept enemy bombers, attack planes and cruise missiles, and can also carry a certain number of ground attack missions to carry out ground attack missions. Fighter fighters are the main types of air combat aircraft of the air force, and can also be used to carry out ground attack missions.

2. Transport aircraft, which are divided into ordinary transport aircraft and strategic transport aircraft, are divided into military, civilian (cargo aircraft) and general purpose in terms of use, and are divided into subsonic transport aircraft, supersonic transport aircraft and hypersonic transport aircraft in terms of speed, which are divided into medium-range and long-range according to the range, and can be divided into medium and large according to the load.

How are airplanes made? Aircraft engines.

How is it made? Let's take a look. There are four steps in the manufacture of an aircraft engine.

Clause. First, the worker wraps the crankshaft with sandbags.

on the bearing, the shaft is tightened, and then polished with a jack.

Grind the shaft well until its diameter meets the requirements. It is a processing plant that specializes in making aircraft engines. Workers apply lubricating oil to the shaft wells and then connect the piston to the crankshaft, which can be rotated by the motor.

Next, he applies lubrication to the edge of the crankcase and attaches a silk thread that acts as a washer. He can guarantee that the engine will not leak.

Clause. 2. Subsequently, the worker places the crankshaft on the main bearing. To prevent the crankcase from hitting the housing when connected, they also installed a bull moment plate. Then the workers use sealant.

Fix the gasket and attach the accessory housing, which will hold all the gears and hoses. In the next step, workers install a cylinder on the piston and attach the parts to the engine. An engine requires a total of four cylinders to be installed and secured.

The worker then inserts a push rod into the two holes and mounts a crank on each rod until the device assembly of the cylinder and valve is completed.

Clause. 3. Immediately afterward, workers clean the engine with steam and then spray anti-rust magnetic paint on their surface. The next step is the spark plug.

One at the top and one at the bottom of each cylinder. Then two magnetos are installed, and they will generate electricity for the spark plugs, followed by the heat shield and the air intake pipe, and then connect the spark plugs to the discharge pipes. After the engine was assembled, workers installed a test propeller on top of him.

Clause. Fourth, the next step is to start the engine like a pilot and check the engine speed, Wensong shouting, fuel pressure and air flow. When everything is in order, the workers put the anti-corrosion oil into the cylinder, which protects the engine during transportation.

By this point, the manufacturing process of aircraft engines had been completely completed.

It will be assembled by the turbofan engine, and will be powered by the gas turbine engine Jingchang car, so as to provide power for the aircraft and ensure the flight of the aircraft. The engine is manufactured by assembly, and many parts are used in the assembly process.

The earliest manufacture of airplanes was inspired by birds, and the stove engine of the aircraft is very important, and the engine of the aircraft also includes many kinds.

In fact, it is to use two wings to support the aircraft, and then polish it out through copper and steel plates. In fact, it is made of steel and iron.

Who wouldn't want to own a private jet of their own? How do private jets work? How are simple airplanes made? This simple airplane might just make your dreams come true.

Clause. First, its skeleton is made of steel pipes and fibers, which contain metal chromium and metal magnesium, which can make steel stronger. The landing gear is made up of this rear wheel, which has two larger wheels in front of it.

These special tires allow aircraft to take off or land on rough ground. Workers spray anti-rust paint onto aluminum core-like beams and rivet them together to form the airplane's wings. The wings are then filled with millimetre-thick aluminium sheets, which are then coated with a special polyurethane paint.

Clause. Second, the fuselage of the aircraft is made of polyester fiber, which is thin and light, but unusually strong. Workers apply adhesive to the frame, and then cover the frame with polyester fibers until they wrap the entire fuselage.

Workers iron these fibers with a hot iron to make them shrink and taut. Next, the installation of the control system begins. First there is the cockpit seat dial, which is made of laser-cut thin aluminum sheets, and then there are two control links, which control the direction of the tires and even the propellers.

Clause. Third, a stainless steel firewall is then installed between the cockpit and the engine, which can protect the pilot from engine heat. After the landing gear, brakes and windshield were installed, the workers began to install the engine and exhaust system, then the aluminum propellers, and the rest of the workers installed the fuel tanks in the wings.

When the fuselage is finished painted, the wings are mounted on the fuselage. The wings of this improvised aircraft need to be mounted higher than other aircraft in order to provide the pilot with better visibility. Then the aircraft was fitted with tempered glass windows and cockpit seats, and an improvised airplane was made.

He is then given a head-to-toe final check, and if the results are up to standard, the pilot will fly it for a test flight.

Private jets need to go through many processes when manufacturing, and they also require a lot of precision parts. Aircraft manufacturing also needs to have chips. This is how security can be guaranteed.

The first step is to put forward technical requirements, that is, what kind of aircraft is needed, the military is proposed by the Air Force, and the civilian is proposed by the marketing departments of major aircraft manufacturing companies.

The second step is technical demonstration, in order to make such an aircraft, what technology, materials, equipment we need. If you can't reach it, then don't think about it, this plane is a castle in the air, and there are just empty ideas.

The third step is to complete the design, and the shape, size, and various parameters of the aircraft are determined, including wind tunnel tests, etc., and the large frame is done.

When necessary, a full-scale prototype is made to see if the parts are as envisioned.

The principle of private jets is to create a pull force through the high-speed rotation of the propeller to tow the aircraft forward. First the skeleton is made, then the fuselage, and finally the powertrain engine.

The scientific name of the aircraft ** is aircraft skin, which is a dimensional part outside the skeleton structure of the aircraft.

Materials: from cloth to alloy.

When the airplane was invented, the skin used was usually a textile cloth: the cloth was wrapped around the wooden or metal structure of the airplane and then coated with a waterproof and airproof material.

This rudimentary skin is easily affected by the environment, so during the First World War, countries focused their attention on the development and application of metal material skins. By the time of World War II, aluminum alloy skin had become the mainstream configuration of fighter aircraft.

Today, the skin material of conventional aircraft is mainly aluminum-magnesium alloy, and some high-performance aircraft will use titanium alloy or composite materials.

Shapes: from single to complex.

According to its shape, aircraft skin can be divided into single curvature skin, double curvature skin and complex shape skin.

As the name suggests, single curvature skin has a relatively simple shape, with curvature in only one direction, and is mostly used in the fuselage and wing of aircraft.

The hyperbolic skin has a pull shape in both directions and is generally used in most air intakes and parts of an aircraft.

Complex shapes, skinned ......Literally, it is used for parts such as the nose hood and wingtips.

Installation: To rivet not weld.

The riveting process is relatively simple, high stability, and more convenient for maintenance: the aircraft is generally larger, and the riveted skin can be used to disassemble and repair the problematic parts during aircraft maintenance, without destroying the structure of the entire aircraft.

The welding process is not only complex and has low stability, but also needs to be disassembled during repair. At present, the alloy materials used in general aircraft skins are prone to defects such as bubbles during welding, resulting in uneven surfaces and ultimately endangering the flight safety of aircraft.

Maintenance: Delicate skin.

Aircraft skins can corrode in complex environments, so they must be protected by a coating on their outside. If necessary, it is also protected by specialized technologies such as cathodic protection.

Damage to the skin of the aircraft will lead to a decrease in the strength of the relevant parts and affect the aerodynamic performance of the aircraft, and ultimately endanger the flight safety of the aircraft. Therefore, the aircraft skin needs to be checked at all times, and the damaged parts must be repaired and replaced in a timely manner.
