| 摘要 |
The invention relates to an acceleration apparatus comprising an accelerator surrounding an acceleration path with the exception of at least its mouth-side end and an acceleration body which is configured for guided and accelerated motion along the acceleration path and is formed by a missile and preferably a propelling housing at least partially surrounding said missile and in engagement therewith. According to the invention, in the accelerator at least two rectilinear guide rails or guide grooves are formed which preferably have a mutual identical angular distance with respect to the bore axis and which are adapted to be brought into constrained engagement with the acceleration body directly and/or indirectly via at least one respective slide shoe on the acceleration body. Furthermore, in the region of the mouth-side end a release means is disposed which is configured for constrained detachment and release of the missile from all other parts of the acceleration body by the movement thereof transversely of the acceleration direction. Preferably, the missile is configured as model for measurements outside the accelerator.
