prethrust
Prethrust refers to the initial phase of propulsion before a vehicle, such as a rocket or spacecraft, achieves full operational thrust. This period is characterized by lower engine output and can involve several distinct stages. For instance, in a rocket launch, prethrust might encompass the engine ignition sequence, where igniters are activated and fuel and oxidizer begin to flow and combust at a controlled rate. This controlled burn ensures a stable start and prevents damage to the engine or vehicle.
Following ignition, the engines gradually increase their power output. This gradual acceleration is often referred to
The concept of prethrust is not limited to rockets. In other fields of engineering, a similar initial
