Brennschluss

Burnout referred to in rocketry the time of shutting off the engines of a missile or rocket stage. In this case, all of the fuel level is not necessarily consumed, but the point is reached in the advancement path of the missile, where the switching off of the engine is provided. In solid rocket but the engines are not suppressible. Burn until the fuel is consumed, however, takes in the final seconds ( - fraction ) of the thrust from. They have therefore no exact burnout, but burn out. Solid rocket boosters are usually already dropped during burnout before the thrust generated by them is covered by its curb weight.

For upper stages of launch vehicles residual fuel is used under circumstances for the specific crash the stage after the suspension of the payload. There are also reignitable upper stages, so that the stage can be used repeatedly after the first burnout for orbit maneuvers or bullet.

After burnout of the rocket motors follows the " free trajectory " (or passive path ). Act no other forces, the flying object continues to move at a constant speed burnout.
