An emergency power unit for providing emergency on board power to an aircraft having apparatus for heating the oxidizing gas contained in the oxidizing gas bottle includes a fuel supply source (14) for supplying fuel, and oxidizing gas bottle (12) containing pressurized oxidizing gas, an oxidizing gas heating device (18) and (20) for heating the pressurized oxidizing gas within the oxidizing gas bottle (12) by using heat energy generated by a combustor (16) wherein the combustor (16) causes combustion of a mixture of fuel and oxidizing gas heated by the oxidizing gas heating device (18) and (20). Hot gases resulting from the combustion of the mixture of fuel and heated oxidizing gas drive the blades of a turbine (32) thereby producing emergency on board power to the aricraft.
