<p>The brake system has an emergency brake (4) e.g. wedge brake, for firmly braking rotors of electric engines (5). The emergency brake is prestressed by force of spring elements in a non-operated state and held by a hook or an element having a predetermined breaking point in the non-operated state. The hook is moved or the element having the predetermined breaking point is destroyed by ignition of the pyrotechnic actuators so that the emergency brake is moved by the force of the spring elements and pressure of propellant charge in a direction of the rotors of the electric engines.</p> |
