**Abstract:**
In this paper, we obtain some relationships between the curvatures of $(r+1)$-dimensional generalized time-like ruled surfaces. We also calculate the drall of a generalized time-like ruled surfaces when the base curve is taken as an orthogonal trajectory of the generated spaces.

**Keywords:** Time-like ruled surface, Minkowski space.

**Classification (MSC2000):** 53B30
