Abstract
An energy generation system for generating energy to be supplied to a chip zapping unit of for example a gas turbine engine comprises an ignition system, e.g. that of the gas turbine engine, the ignition system having an energy output and configured to supply operational energy to the energy output, and the chip zapping unit having an energy input, the energy input coupled to the energy output of the ignition system to receive the operational energy therefrom. Such an energy generation system generates the operational energy needed for the chip zapping unit directly from the ignition system thus avoiding pulse generation circuitry inside an electronic control unit.
