Hello, my name is Zahra Bayoudh and I study Pure and Applied Science, and I am currently in my second year. This program means that we study advanced mathematics, physics, and chemistry to understand how the physical world works. Even though I really love my program, I want to specialize later on. I plan to study Aerospace Engineering at university because I am fascinated by aircraft, fluid dynamics, and space exploration.
Aerospace is a complex field of study and has a lot of incomprehensible words and this why I created this glossary. This glossary helped me understand and memorize some of the technical words, and I hope it will help other students like me who gets stressed out when they don't understand the meaning of a technical word. They can precise the word's French translation, or if, they want they can see exactly what the concept looks like in the real world.
aerodynamics
noun
The study of how gases interact with moving bodies, such as aircraft wings.
Example: Engineers use wind tunnels to test the aerodynamics of a new fighter jet profile.
en: aérodynamique
aileron
noun
A hinged flight control surface on the wing that controls the aircraft's roll (banking).
Example: The pilot deflected the aileron to roll the aircraft to the left.

avionics
noun
The electronic systems used on aircraft, satellites, and spacecraft (e.g., navigation, communications).
Example: Modern commercial aircraft rely heavily on advanced avionics for autonomous navigation.
en: avionique
boundary layer
noun
The thin layer of fluid or air molecules directly adjacent to the surface of an aircraft wing.
Example: The friction within the boundary layer accounts for a significant portion of aerodynamic drag.
en: couche limite
drag
noun
The aerodynamic force that opposes an aircraft's motion through the air.
Example: A sleek fuselage shape helps minimize aerodynamic drag and save fuel.
en: traînée
engineering
noun
Engineering is the practical application of science and mathematics to design, build, and improve structures, machines, systems, and processes that solve human problems.

fuselage
noun
The main central body of an aircraft that holds the crew, passengers, or cargo.
Example: The fuselage must withstand extreme pressure changes during high-altitude flights.
en: fuselage
lift
noun
The upward aerodynamic force generated by the wings that overcomes the aircraft's weight.
Example: The wings must generate enough lift to overcome the total weight of the aircraft.
en: portance
mach number
noun phrase
The ratio of the speed of an object to the speed of sound in the surrounding medium.
Example: The supersonic aircraft exceeded a Mach number of 2.0 during its test flight.
en: nombre de mach
payload
noun
The carrying capacity of an aircraft or spacecraft, including passengers, cargo, or scientific instruments.
Example: The supersonic aircraft exceeded a Mach number of 2.0 during its test flight.
en: charge utile
propulsion
noun
The mechanism or engine (e.g., turbojet, rocket) that generates thrust to move a vehicle forward.
Example: Ion propulsion systems provide low thrust but high efficiency for deep-space missions.
en: propulsion
rudder
A vertical control surface attached to the tail used to steer and control yaw (side-to-side movement).
Example: The pilot pushed the left pedal to deflect the rudder and counter the crosswind.
en: gouverne de direction
telemetry
noun
Example: Ground control monitored real-time telemetry data transmitted by the spacecraft.
en: télémesure
thrust
noun
The forward force produced by the propulsion system to overcome aerodynamic drag.
Example: Jet engines generate massive thrust by accelerating hot exhaust gases backward.
en: poussée
trajectory
noun
The curved flight path that an aircraft, rocket, or missile follows through space or the atmosphere.
Example: Computers calculated the optimal trajectory to send the probe to Mars.
