Abstract: An auxiliary propulsion apparatus of an air vehicle may include an engine mounted in a fuselage of the air vehicle, a generator configured to be driven using power from the engine, a compressor configured to be driven by the engine or the generator, a battery configured to store electricity generated by the generator, an electricity distributor connected to the generator, the battery and the main propulsion apparatus and configured to distribute electricity generated by the generator to the battery and to a main propulsion apparatus, and at least one nozzle device configured to jet high-pressure gas, supplied from the compressor, to an outside of the fuselage.

Abstract: A method for processing an authentication failed/authorization denied subscribers by intelligent network is disclosed in which when a call originated by a subscriber is authentication-failed or authorization-denied in a communication service network, a phone communication is connected to a service center or to a phone number designated by the subscriber of the corresponding terminal, or connected to a special service equipment such as an Intelligent Peripheral (IP), or is processed as a normal call. The identity of the subscriber can thus be recognized, and the subscriber's legitimacy can be determined. Additionally, various announcements, suitable to certain situations can be provided, or a normal call service can be provided to the subscriber. Additionally, communication between the subscriber and a person in charge of the subscriber in a service center can be established.
