Here is a lexicon of specific terms for the aerospace industry and techniques used in this industry.
Intended to signal a danger or an obstacle, or to mark out an aerial traffic route (e.g. beacon lights on wind farms, tall buildings, etc.).
Branch of fluid dynamics that looks at how objects move through air and the resulting physical effects.
All the disciplines related to flight through the air and aircraft construction.
All the disciplines related to aeronautics and astronautics.
Vehicle for moving through the Earth's atmosphere.
Procedure that involves surrounding a piece of metal with a protective layer (using electrolysis) that is both very thin and very dense.
This process is often used in aeronautics for its anti-corrosive properties, and it also provides a good surface for paint adhesion.
Device propelled through space by a launcher, to be sent into orbit around a planet. The satellites in orbit around the Earth are mainly used for telecommunications, scientific research and meteorological observations. .
All the disciplines related to flight through space and spacecraft construction. .
Electronic equipment and information technology allowing or assisting with aircraft navigation: radars, GPS, automatic pilot, radio, etc. .
Equipment used to train astronauts and military pilots in order to test their resistance to rapid acceleration. In the future, centrifuges could also be used in spaceships, to create artificial gravity. .
Protection against electromagnetic radiation using a screen (metallic cloth) or paint. .
Fibre optic cable:
Thin silicon or plastic wire that conducts light. Its high data transmission rate (at the speed of light) and the fact that it is not affected by electromagnetic interference mean it can be used for many aeronautical applications. .
Suitcase or protective case designed especially for wedging and transporting material by air in difficult conditions (vibrations, impact, temperature, humidity, etc.). .
System that realistically reproduces the flight conditions (take-off, landing, turbulence, weightlessness) of an aircraft or spacecraft. It is used to train and improve the fitness levels of pilots. .
In astronautics, heat shields are used to protect spacecraft from kinetic heating on re-entry into the atmosphere. .
Heat created by friction when a spacecraft enters the atmosphere. .
Process of reshaping or reducing a metal to thin layers. .
Self-propelled rocket used to launch satellites or space probes into space. .
Circular sealing ring that can be used at various pressures and temperatures. .
Equipment used specifically for manually cleaning and degreasing mechanical parts. .
All of the elements transported by a spacecraft to carry out a given task, as opposed to the weight of the spacecraft itself. .
(or polyether ether ketone) A semi-crystalline plastic material used in aeronautical manufacturing for its ability to withstand high temperatures and its capacity for radioresistance. .
Polymer resin (fluocarbon) used in aeronautics for its resistance to high temperatures and repeated flexing. .
Photovoltaic solar panel:
Equipment used to capture sunlight and convert it into electricity using photovoltaic cells. In astronautics, solar panels are used to supply electricity to artificial satellites. .
Mechanism used to keep an aircraft or other vehicle flying at high altitude at normal atmospheric pressure. .
Acronym for polytetrafluoroethylene, or TEFLON. Anti-adhesive plastic material which is also resistant to acid and heat, used to manufacture joints and fittings. .
Detection tool used to guide aircraft during flight. The radar detects the presence of objects or targets by means of radio waves. It emits a signal which bounces back, and the return time determines the position and the distance of the target in question. .
Technique allowing information to be collected remotely by an aircraft or satellite. .
Procedure for cleaning or modifying the surface of an object by high-speed projection of micro balls. .
Particular kind of shot blasting used to improve the properties of a surface. .
Reusable spacecraft for transporting astronauts or material. It is launched by a rocket and lands like an aeroplane. .
Chamber or cabinet that reproduces extreme thermal or climatic conditions. Used to test the solidity of materials. .
Bonding procedure linking plastic resin to carbon fibres. A thermoplastic material can be softened several times when it is heated to a certain temperature. .
Abrasive fabric made of nylon and synthetic resins, to which abrasive grains are added. It has several advantages, including its suppleness, which allows it to be used on curved surfaces, and its resistance to heat. .
