ABSTRACT:
The problem of excessive weight in an aircraft 10 powered by at least one turbine engine 12 as a result of the incorporation of both a starter for the turbine engine 12 and a source of emergency power is avoided by utilizing a turbine wheel 62 to alternatively start the engine 12 or drive an emergency power generator 102. The turbine wheel 62 may be driven either by compressed air from a ground source 34 or an engine bleed 32 or, in the alternative, by hot gases of combustion from a stored energy source 36 in an emergency situation.
