When a rocket is launched by a rail launcher, the rocket receives tip-off angular velocity caused by the moment due to engagement of the tail hanger of the rocket on the rail after clearance of rocket C.G. from the tip of the rail. This paper analyses one occasion, when small test rocket launched from a rail launcher experienced unexpected large pitch-down tip-off angular velocity. The rocket had two hangers, one of which was constrained by a detent mechanism prior to launch. When the rocket motor was fired, detent action caused torsional deflection of the shaft, which supported teh rail launcher. When the hangers got free, the shaft started oscillatory motion, which amplified the tip-off angular velocity of the rocket. Analysis of the dynamics of the rail launcher and the rocket was performed and numerical calculation was made to simulate the tip-off velocity. Measures for improvement were summarized.
