#propulsion

• Air-consuming — Consuming, absorbing, or utilizing large amounts of air or atmospheric oxygen to function, live, or sustain itself. In biology, the term describes organisms or processes strictly dependent on open air; in technology, it applies to internal combustion engines or turbines that require a massive air intake to create the fuel mixture.
• Air-breathing jet — Utilizing the reaction of atmospheric air absorbed and expelled at high speed to produce the propulsion force necessary for movement; a system, engine, or aircraft based on burning a fuel in atmospheric oxygen. This type of structural propulsion is specific to modern turbojet airplanes, differing from rockets in that it does not carry its own oxidizer.
• Jet engine — An air-breathing jet engine (reactive) that utilizes surrounding air as an oxidizer for burning fuel and generating propulsion force through the rapid expulsion of exhaust gases. Unlike rocket engines, this structural mechanical assembly fully depends on the presence of Earth's atmosphere to function, being widely used in modern airliners and supersonic aircraft.
• Hover-scooter — A small, individual hybrid recreational vehicle, structurally designed to move at a low altitude above the ground or water by utilizing the air cushion principle or steerable propulsion propellers. This mechanical device combines the handling ease of a terrestrial scooter with aerodynamic elements specific to ultralight aircraft.
• Anterotor — Rotating assembly located at the front of an aerial vehicle, propulsion system, or industrial equipment, having the primary role of generating initial thrust or absorbing fluid kinetic air mass. In specialized helicopters or advanced drones, this front rotor provides pitch control.
• Front-wheel drive — Propulsion system or mechanical layout where the motive force is applied exclusively to the front axle of a vehicle, ensuring that the structural assembly is pulled by the anterior wheels. In automotive dynamics, this type of front-wheel drive optimizes directional stability.
• Anti-gravitational — Tending to cancel, counteract, or reverse the effect of the gravitational attraction force; pertaining to antigravity. In theoretical cosmology, it describes mechanical properties of dark energy, which exerts a negative pressure with an anti-gravitational effect at a cosmic scale.
• Thrower — A noun or adjective designating a person specialized in or a technical device designed for launching, propelling, or throwing an object, a projectile, or a substance into space. In sports, it indicates an athlete competing in throwing events (javelin, discus, hammer, shot put) or the player who throws the ball back into play, while in military or industrial terminology, it refers to mechanical installations or weapons intended for projecting loads at a distance.
• Astronautic — Belonging to astronautics, relating to astronautics; referring to the techniques, technologies, vehicles, or physical laws involved in the navigation and flight of manned or automated craft outside the Earth's atmosphere. The term defines structural engineering elements, propulsion systems, orbital trajectories, or research missions conducted in deep outer space.
• Astronautics — The science and branch of modern technology dealing with the study, design, construction, and operation of spacecraft (rockets, satellites, probes, orbital stations) intended for travel or research outside the Earth's atmosphere. This interdisciplinary discipline gathers advanced knowledge of celestial mechanics (astrodynamics), chemical or nuclear propulsion, onboard electronics, and space medicine to ensure the exploration of the universe.
• Astronautical engineer — A highly qualified technician, engineer, or specialist in the field of astronautics, responsible for the direct application of astrodynamics laws, the design of propulsion systems, or the structural maintenance of spacecraft and orbital stations. Unlike an astronaut, they do not travel into outer space, but instead coordinate the mathematical, engineering, and logistical aspects of extra-atmospheric flight from the ground.
• Amphibious vehicle — A motor vehicle specially designed and structurally equipped to move with equal efficiency both on land and on water; a military or rescue car capable of floating and navigating due to a watertight hull and its own aquatic propulsion system (propeller or water jet).
• Autochory — The biological and biomechanical process of autonomous dispersal or spreading of seeds, spores, or fruits by a plant, utilizing exclusively its own mechanisms and structures (such as capsule explosion, self-propulsion, or cellular tension), without the help of external vectors like wind, water, or animals. This structural strategy usually limits dispersal to the immediate geographic area.
• Electric car — A rare technical neologism used to designate a car fully propelled by electric motors powered by its own rechargeable batteries; a modern electric vehicle capable of autonomous driving.
• To self-propel — To propel oneself or move a vehicle or body by its own energetic and motor means, structurally integrated within it, without relying on an external pulling or pushing force. In transportation and aerospace engineering, it describes the ability of a device, vehicle, or projectile to generate the force required for travel by consuming a fuel or energy source stored on board.
• Self-propulsion — The act of self-propelling and its result; a technical or mechanical process through which a vehicle, projectile, or body generates its force of motion and spatial displacement utilizing an internal energy source or its own engine, without the input of an external pulling or pushing force. This structural system is fundamental in the design of rockets, spacecraft, submarines, and heavy self-propelled machinery, optimizing the operational independence of the assembly.
• Self-propulsion — The structural capacity of a vehicle, technical system, or body to move through space by generating motive force using an onboard engine or internal energy source, without the input of an external mechanical action (such as towing or pushing). This kinematic principle is fundamental in designing motor vehicles, modern artillery systems, rockets, and combine harvesters, guaranteeing full operational independence during travel.
• Propulsion unit — 1. (As a neuter noun) A mechanical device, engine, or complex structural technical assembly capable of generating and transmitting the pulling or pushing force required for the autonomous movement of a body or vehicle. 2. (As an adjective) Serving for self-propulsion; possessing the capacity to generate independent movement through its own energetic forces.
• Self-propulsion — The capacity or autonomous propulsion system through which a vehicle, machinery, or mechanical device moves under its own power, utilizing an internal engine integrated into its structure, without depending on an external towing force (animal, manual, or from another vehicle). The concept underlies the development of all modern self-propelled machinery.
• Soaring — The act of rushing or propelling and its result; the physical act through which a body gains momentum, propulsion, or launching speed; abstractly or spiritually, it represents the drive, enthusiastic surge, or inner impulse of total involvement in a creative or idealistic activity. Unlike 'avânt', the form in '-re' emphasizes the dynamic process and the unfolding of the action itself.
