Abstract

The invention seeks to provide emergency starters that allow responsiveness of this order of magnitude namely within a few seconds without having the disadvantages associated with the mass and size of the backup hydraulic or pneumatic starters mentioned hereinabove. To achieve this the present invention proposes coupling an instantaneous gas thrust of pyrotechnic type with a positive displacement transmission generator in conjunction with automatic coupling to/uncoupling from the set that is to be started. An emergency start up system (10) according to the invention comprises at least one pyrotechnic gas generator (5) connected to an electric initiator (3) itself connected to a computer a positive displacement motor (100) housing straight cut spur gears the pyrotechnic gas generator (5) being coupled to the motor (100) by an inlet (121) in the casing (120). The motor (100) comprises a means of connection capable of moving at one end of the transmission shaft (40b) so as to be able to couple this transmission shaft to a receiving shaft of the set that is to be started via a centrifugal clutch (170).
