Abstract: A launch apparatus for launching a missile includes a launching tube extending in a longitudinal direction. The launching tube has an outlet opening at a first end. An acceleration device arranged in the region of a second end of the launching tube includes a gas generator to generate a gas mass flow, and a bag formed from a textile fabric. The bag is coupled to a diffuser of the gas generator via an end opening and inflates longitudinally by the gas mass flow generated by the gas generator to accelerate the missile. The bag has a gas permeability within a range of between 10 l dm?2 min?1 and 30 l dm?2 min?1. When inflated, a cross section of the bag alternatively or additionally tapers from the end opening to a minimal cross section along the longitudinal direction and increases in size to an end opposite the end opening.
