Payload fairing

Payload fairing is one of the main components of a launch vehicle. The fairing protects the payload during the ascent against the impact of the atmosphere (aerodynamic pressure and aerodynamic heating). More recently, an additional function is to maintain the cleanroom environment for precision instruments.

Outside the atmosphere the fairing is jettisoned, exposing the payload. At this moment mechanical shocks and a spike in acceleration might be observed.
