Overview

"Light aircraft" (balloon,airshipEtc.) and "heavy aircraft" (グ ラ イ ダ ー,airplaneEtc.)[1][2].. A light aircraft is one that utilizes the fact that gas, which is lighter than air, has static buoyancy.WingsWorking air dynamicsLiftIs to use[1].airplane,Rotorcraft,Glider,airshipEtc. are included.

The aircraftShipthe same asCitizenshipIs registered and alwaysAircraft symbolIt is obligatory to display it in an easily visible position (fuselage, wing, etc.)[1]..As a result, the country / region to which the aircraft belongs andJurisdiction-Diplomatic protectionIs identified where is[1].

Legal definition

Aircraft are legally given different definitions for different purposes. In the following, a typical definition from the perspective of aviation administration is illustrated.

Definition by ICAO
Chicago Convention(International Civil Aviation Convention) does not have a general definition of aircraft,International Civil Aviation OrganizationIn some of its annexes to the Convention (ICAO), "the bearing capacity in the atmosphere is defined as thereactionAny equipment you can get from[3] I am trying. In addition, the phrase "other than the reaction of air on the surface of the earth" is1967 May 11It was added toHovercraftWill be excluded.
U.S. Aviation Administrative Definition
米 国 OfUnited States CodePart 49, Part VII, Part A (Air Traffic and Safety) states "any contrivance invented, used, or designed to navigate, or fly in, the air. , Or any designed device)” (49 USC §40102(a)(6)). On the other hand, in Federal Regulations Vol. 14 Chapter 1 (Federal Aviation Bureau of the Ministry of Transport), "a device that is used or intended to be used for flight in the air" is used or used. Device intended to be)' (14 CFR §1.1).
Japanese Aviation Administration Definition
Japan OfAviation lawThen, "People can ride and serve for aviationairplane,Rotorcraft,Glideras well as the airshipMoreCabinet Order"Equipment that can be used for aviation as specified in". (Article 2, Paragraph 1 of the Civil Aviation Law) However, there is currently no equipment that falls under the Cabinet Order. Also,balloon,Unmanned aerial vehicle(Aviation Law, Article 2, paragraph 22),rocketEtc. are not included in the aircraft because they are out of this definition[1].

Classification of aircraft

There are various taxonomies. Generally the aircraftdensity 空 気LighterLight aircraftAnd heavier than airHeavy aircraftIt is roughly divided into two. Besides, based on the operator of the aircraft and the purpose of operation, etc.Commercial aircraft"/"Military aircraftThere is a method to classify. In addition, "manned aircraft"/"Drone(Unmanned aerial vehicle)"are categorized. AlsoengineDepending on the type ofTurbine(Machine)"/"piston(Machine)" (or "Reciprocating(Machine)”).

By principle

Light aircraft

Heavy aircraft

Wingsaroundatmosphere OfItineraryCaused byLiftAn aircraft that floats and flies with (dynamic lift). Depending on the wing type, it is divided into fixed-wing aircraft and rotary-wing aircraft. With HTA (Heavier-Than-Air) aircraft or aerodyne.

Fixed wing aircraft
An aircraft that has wings for lift and is fixed to the airframe, and obtains lift by moving in the atmosphere. Airframe with variable wing plane shape (Variable wing aircraft) Is also included.

A fixed wing aircraft equipped with a propulsion device. To create propulsionengineIs a manned aircraftJet engine,Piston engineSuch asInternal combustion engineIs the main. Generally not 1,500 although not classified by ICAOkgA single-engine reciprocating aircraft with a seating capacity of 2-6 people is called a light aircraft.JapanAccording to the aviation law of Japan, a navigation aircraft with a simple structure equipped with a landing (water) device and a power unit is not an airplaneUltralight motiveClassify.
Vertical takeoff and landing aircraft
An airplane that can take off and land vertically like a helicopter. Some jet planes have their engine nozzles facing downwards, and some have lift engines for vertical takeoff and landing separately from those for propulsion. Vertical takeoff and landing by tilting the rotorTilt rotor machineEtc. also have the characteristics of a rotary wing aircraft. Also, although you cannot take off verticallyShort-range takeoff vertical landing aircraft (STOVL)There is also what is called.
グ ラ イ ダ ー(Glider)
Fixed-wing aircraft that do not have power. Towing by another plane or on the groundwinchTake off by external power such as cable winding by, and glide after takeoff.[7]..Those equipped with a propulsion device for takeoff and re-climbingMotor gliderCalled. The crew is limited to 2 people.
Paragliding,hang glidingIs not an aircraft under Japanese aviation law.
Heavy airship

Rotorcraft
An aircraft that floats in the air due to lift generated by its rotating wings.
helicopter
The one that drives the rotor with the power of the engine. Propulsion is obtained by slightly tilting the axis of the rotor.
Auto gyro
An aircraft whose power is not transmitted to the rotor blades. It has a propulsion device for forward movement.
Orniopter(Flapping machine)
The one that gains lift by flapping its wings. It exists in radio control. Manned aircraft have yet to successfully take off without auxiliary power[Note 1].
Heavy aircraft without lift

Airplanes are one of the main weapons and the three majorServiceone ofair forceIs the core[13]..It is not only the Air Force that owns military aircraftNavy,armyAlso have each[14]..Military aircraftFighter,BomberWith airplanes for battle, such asTransport aircraftThere are airplanes that are not used for direct combat.

private

The plane isAutomobile,列車,ShipAt the same time, it is one of the main means of transportation in modern society, and a transportation system that combines these four types has been constructed.[15].. For passenger transportation over 700km, the advantage of the fastest airplane among the major transportation systems has been established.[16]..For this reason, large aircraft are mainly used for transportation between nations and long-distance metropolitan areas, but on the other hand, there are many routes that fly between small cities and remote islands due to their speed, and in this case small aircraft are often used.[17]..Small between small citiesRegional jetHowever, smaller propeller planes are used on remote islands.[18], In some remote islands where the land is too small to build an airport, helicopter regular passenger routes are also available.[19]..In the case of freight transportation, airplanes are often used for freight that requires expensive and rapid transportation due to the high operating cost.[20].

General aviation

Civil aviation other than regular route transportationGeneral aviationCollectively called (general aviation).In parts of the Australian continent, which are extremely sparsely populated and vast, many individuals own small planes and use them like private cars.[21]..Also overseas bigCompany,wealthy classBecause of its mobility, it is for personal movement, etc.Business jetOften owns, and its use is skyrocketing[22].

In addition to transportation and transportation, aircraft are often used for scenic flights.TheseTourismSmall aircraft and helicopters are mainly used for flights[23]..Sightseeing flights by airships are also carried out in some countries, but in Japan in 2007Nippon AirshipAlthough the airship sightseeing flight was started by[24], The company went bankrupt in 2010 and stopped operation[25].

Pesticide,fertilizer,seedEtc. are efficiently sprayed on agricultural landAgricultural machineIs also used all over the world.Many people use small planes, but in JapanYamaha MotorDeveloped the world's first industrial unmanned helicopter in 1987[26], Used in about 4% of paddy fields in Japan, and is widely used[27].AdsAirships are sometimes used for this purpose, and have long been the main use of airships after World War II.[28]..In Japan as Japan's first advertising airship in 1968Kid ColorSince the inaugurationRainbowVarious advertising airships were once in service[29].

Take an aircraftSports TheSky sportsIs collectively referred to asAerobatic flight,Air race,Hot air balloon competition,グ ラ イ ダ ーbyGliding competition,sky divingVarious sports are included.Glider competition has existed for a long time in Sky Sports, and various flight methods were developed and further developed in the 1930s.It is a competition that is popular mainly in Europe, and the world championship is held once every two years.[30]..In hot air balloon competition, since 1973Hot air balloon world championshipIs now held every other year, and domestic races are also held in Japan[31]..Aerobatic flights around the worldAir showIt is often held as an attraction, but the military shows its skillpublic relationsTo utilizeAerobatic corpsOften in possession of JapaneseJapan Air Self-Defense ForceAlsoBlue ImpulseI have an acrobatics team called[32]..The air race was first held in France in 1909 and has been held all over the world since then.[33]..These sky sports were founded in 1905International Aviation FederationIs in charge, and the headquarters isスイス OfLausanneIs located in[34].

History

Balloons and gliders

Human beings have longed to fly in the sky, and although various flying machines were conceived, it took a long time to realize them.The machine that flew in the sky for the first time with a person actually on boardFrance OfMontgolfier BrothersInvented byhot air balloonso,1783 The manned flight was successful on November 11st.Almost at the same timeJacques CharlesByGas balloonWas also invented and succeeded in manned flight on December 10, 12 days after the first flight of Montgolfier.The success of the balloon caused a temporary boom,French RevolutionLater, it was temporarily used by the French army for military purposes, but it was soon discontinued because it could not move freely in the air.[37]..On the other hand, in the 19th centuryGeorge CayleyConducted aviation research in the 1890sOtto LillienthalHowever, flight research gradually progressed, such as repeating glider experiments.However, power airplanes at that time were still in the research stage, and non-powered aircraft such as balloons and gliders were the mainstream.[38].

The appearance of an airplane

1903 ToThe United States of America OfWright brothersFly by power, so-calledairplaneInvented[39]..Airplanes developed rapidly and began in 1914.World War IThen a fierce aerial battle was held[40]..After World War I, the surplus airplanes became popular for commercial flights by the private sector, and in 1919, regular passenger operations by airships and airplanes began.[41]..In addition, the performance of airplanes has made great strides, and in 1927Charles Lindbergh Transatlantic solo non-landing flightSucceeded[42]..During this period, not only ordinary airplanes but also other aircraft were aimed at commercialization, and in the 1930s on long-haul routes.Flying boatIs often adopted[43]Also, airships were one of the important means of air transportation.But the airship was in 1937Hindenburg explosionIt will not be used after that[44]Also, flying boats were replaced by airplanes in the 1940s.[45].. In 1936, it was Germany's first practical helicopter.Focke-WulfFw 61Is being developed[46].

After World War II, in the late 1950sBoeing 707Even on passenger planesJetBecomes mainstream[47]In 1969, the world's firstWide body machineIsBoeing 747Is in service[48], Passenger airplanes have become larger and faster[49]..Furthermore, in 1968, the Soviet UnionTu-144, By England and France in 1969Concorde Supersonic airlinerAlthough it was developed as a high-speed engine, the Tu-144 was soon discontinued, and Concorde was discontinued in 1976 due to various problems such as noise and poor fuel economy. Since then, supersonic passenger aircraft have been manufactured. It has not been[50].. In 2003, Concorde ended its operation, and the operation of supersonic passenger planes itself disappeared.[51]..While the speedup has settled down, efficiency has been further improved by increasing the size and improving fuel efficiency.[52].

Relationship with ship

Aviation laws, terms, customs,ShipMany are derived from. For example, the following examples can be given.

  • Passenger planeLet's compare it to a passenger ship,ship)[53],kitchenToGalley』I call it.
  • EnglishLet’s call the conductor “Captain (captain)”. (JapaneseThen the aircraftCaptain, The shipCaptain
  • The crew memberscrew)” and is called an “air crew.Flight attendantIs called a stewardess because it is a passenger ship crew member.
  • On the left side of the aircraftPortside(port side), right side of the aircraft toStarboard side(starboard side)".
  • In the air, drive on the right as you would at sea.Starboard boat priority principleThere is a rule based on, and a red light on the port side and a green light on the starboard side.
  • Set the departure/arrival location to "empty"HarborCall it "(air"port")". Even if there are doors on both sides, there is no legal provision, and basically you get on and off from the port side as well as a ship. Most of the models that open the canopy and board are hinged on the right side.
  • Charter contractSimilar toAircraft leasingIs performed.

A manufacturer that manufactures both aircraft and shipsKawasaki Heavy Industries(Since 1918),Third(Starting entry in 2015),Tsuneishi Holdings(Acquired aircraft manufacturer in 2015) and so on.

Take off and land on land runwaysAmphibious aircraftIs basically treated as an aircraft.

Aviation industry

Although there are many companies in the aviation industry, the oligopoly is quite advanced, especially the production of large passenger planes in the United States.BoeingAnd EuropeanAirbusIs almost concentrated in the two major companies[54]..However, in the case of airplanes, each part is distributed and produced all over the world.[55]..The two companies have made little progress in manufacturing small passenger planes.Regional jetIs in BrazilEmbraerAnd canadaBombardier AerospaceHas been competing for many years as two major companies[56]..For smaller airplanes, in addition to Embraer and Bombardier,Cessna,Gulfstream AerospaceSome companies are manufacturing[57].

Aircraft use only certified parts and are basically made to order, so even a small aircraft takes time to deliver and is expensive. For this reason, the second-hand market is developing, with manufacturers selling refurbished certified second-hand machines and a large number of vendors specializing in second-hand machines. As long as there are parts that haveBoeingAirbusOf the two major companies have set up organizations to promote reuse (AFRA,PAMELA). Also, buying and selling parts[58], Many companies develop and sell repair parts and upgrade parts for discontinued aircraft[Note 2].

Buying and selling large passenger aircraftAirlinesHowever, large aircraft are very expensive, it takes several years to deliver them, and it is difficult to adjust to meet demand, so it enters between manufacturers and airlines.Aircraft leasingLarge relationships with financial institutions, such as the existence of many specialized companies[59].. In addition to affirmations, contracts have a unique style such as temporarily contracting for additional purchases, fixing them according to financial conditions and demand, and buying and selling purchase rights between airlines. Since it takes a long time to complete, there is a case where the airline company's management deteriorates after ordering and the aircraft that cannot be paid and is retained by the manufacturer is sold as a new old machine.[60].. Aircraft have a mechanical lifeLegal useful lifeBecause there is a large difference in sales, even parts can be sold, so a large market is formed with many transactions as tax saving, such as a company irrelevant to the aviation industry operating an aircraft leasing business for tax saving[58].. Small machines andBusiness jet TheFractional ownershipThis has activated the market for individuals.

Aircraft costs a lot of money to maintain and store, and a large number of qualified specialists are needed.Therefore, in addition to the manufacturers that manufacture aircraft and many companies that manufacture each component, maintenance and storage operations are also required. Professional media that provides information to specialized companies, temporary staffing companies that dispatch pilots and mechanics, airlines and leasing companies[61] Forms the aviation industry.
