Abstract

The invention relates to a firing direction system for adjusting a rocket launcher, and includes a drive motor (9) that is connected via a safety brake (2-8) with a drive shaft (1) for adjusting the rocket launcher, whereby a rotation of the drive shaft (1) in a first direction effects a raising of the rocket launcher, and a rotation in the opposite direction effects a lowering of the rocket launcher, whereby the safety brake prevents a back-driving torque of the rocket launcher from effecting a rotation of the drive shaft (1) in the opposite direction. In addition, an electric motor (11) is disposed on the drive shaft (1) and is controlled is such a way that upon a rotation of the drive shaft in the first direction, the electric motor effects an additional torque of the drive shaft (1) in the first direction, and upon rotation of the drive shaft in the opposite direction effects a recovery of energy.
