 The pyrofixing devices are
widely used in the space rocketry for locking of the lock systems of deployable objects and their release at deployment by an electric
signal. The pyrofixing devices are used for multiple mechanical deployment of the lock systems at ground preparation; they don't eject
the combustion products of the pyroelement and the elements of the locking device into the environment.
The pyrofixing devices solve the problem of reliable locking and release of the locking systems of deployable objects
by an electric signal; they are of small weight and high reliability P>0.99995 verified by experimental development and in the process
of multiple launches of the launch vehicles.
