large aircraft ground starter

Abstract

The invention discloses a giant plane ground starting device which comprises a turboshaft engine, a centrifugal compressor and an alternating-current generator, wherein the turboshaft engine is used for outputting power; the centrifugal compressor is connected with the turboshaft engine and is used for supercharging the input air under the driving of the power output by the turboshaft engine and supplying the supercharged air to giant planes so as to realize multiple synchronous starting of the giant planes; the alternating-current generator is connected with the turboshaft engine and is used for converting the power output by the turboshaft engine into electricity and supplying the electricity to the giant planes for charging. According to the giant plane ground starting device, an airborne auxiliary power plant is removed, and thus the multiple starting of the giant planes is realized; the structure of the starting system of the giant plane is simplified, and thus the cost is reduced; airborne fuel is saved, the service life is long, and the economical efficiency is good; the maintenance is convenient, the giant plane ground starting device can be maintained on the ground or in a room and does not need to be disassembled and assembled or maintained on the giant plane; the range of application is wide, the giant plane ground starting device can start a carrier-borne aircraft and can also start a combustion gas turbine on a warship; the dead weight during the flight is reduced, and the tactical and technical index is improved.

Description

technical field [0001] The invention relates to the field of auxiliary power devices, in particular to a ground starting device for large aircraft. Background technique [0002] Modern aircraft have self-starting capabilities. There are three types of starters commonly used in aero-engines: electric starters, air turbine starters and gas turbine starters. Small and medium-sized aircraft generally only have one aeroengine (single engine), and most of them use direct electric starting, which is as simple as starting a car. Large aircrafts are generally equipped with two or more aero-engines, which cannot be started simultaneously by themselves, but one after the other. Because the energy density of power batteries is lower than that of fuel, the price is more expensive than fuel, the starting current of large engines is large, and the maintenance workload of batteries is large, etc., large aircraft do not carry a lot of power batteries, so direct electric starters are genera...
