PARABRAKE Meaning and
Definition
-
A parabrake, short for parachute brake, is a mechanical or aerodynamic device used to slow down or stop the forward motion of an object, particularly aircraft, rockets, or vehicles. It primarily functions by creating drag or increasing air resistance, which reduces the speed and decelerates the object in motion.
In aviation, a parabrake is often utilized as an additional braking system during landing or emergencies. It acts as a temporary substitute for conventional brakes, especially in situations where the aircraft requires a shorter landing distance. When a parabrake is deployed, it increases the air resistance, resulting in a decreased speed and increased drag force, which counteracts the aircraft's momentum.
Parabrakes can come in various forms, such as drogue parachutes, cone-shaped devices, or hinged plates that extend into the airstream to induce drag. The structural design and deployment mechanism of a parabrake depend on the specific application and intended use.
Beyond aviation, parabrakes find applications in space exploration and land-based vehicles to facilitate controlled descents, reduce speeds, or enhance stability. They allow for efficient deceleration, increased maneuverability, and improved overall safety, particularly in situations where conventional braking systems are insufficient or not available.
In summary, a parabrake is a mechanical or aerodynamic device that generates drag or air resistance, primarily used to slow down or stop the forward motion of flying objects, rockets, or vehicles, ultimately enhancing control and safety during landings, descents, or emergency scenarios.

Etymology of PARABRAKE
The word "parabrake" is a blend of two words: "parachute" and "brake".
1. Parachute: The term "parachute" originates from the French word "parachute", which was formed by combining the prefix "para-" (meaning "against" or "counter") with the noun "chute" (meaning "fall" or "drop"). The French term was created by André-Gustave Citroën and was initially used to describe a safety device that slows down the fall of an object or person through the air.
2. Brake: The term "brake" derives from Middle English "braken" and Old English "bracu", which mean "to break", "to slow down", or "impediment". In the context of vehicles, a brake is a device used to slow down or stop the motion of the vehicle.
