Ground starting device for turbojet engine

Abstract

The invention relates to the technical field of auxiliary power devices, in particular to a turbojet engine ground starting device, comprising: an electrical system, the electrical system includes: a driver, an adjustable power supply, a voltage stabilized power supply, a relay, a fuel system, and the fuel system includes an ignition After the fuel pump, priority fuel pump and fuel filter, the ignition fuel pump and the priority fuel pump work, the fuel flows from the external fuel tank in two ways through the ignition oil input and priority fuel input interfaces on the ground starter panel, enters the internal two-way fuel filter, and then to the ignition oil pump and the priority oil pump, and then output from the panel ignition oil output interface and the priority oil output interface to the two-way oil inlet interface of the engine. The ground starting device of the turbojet engine has high starting efficiency and can be started in a special place without being affected by the terrain. , the device structure is simple, after the small-sized turbojet engine is put into flight, multiple sets of the ground starting device can be used on the test flight site so as to realize the tasks of simultaneous starting of multiple machines and simultaneous flight of multiple machines.

Description

technical field [0001] The invention relates to the technical field of auxiliary power devices, in particular to a ground starting device for a turbojet engine. Background technique [0002] For turbojet engines, in order to start the engine reliably and meet a certain starting acceleration, it is generally used to start with a ground air source vehicle or a windmill to achieve a suitable speed. This type of operation is complicated and the starting equipment is inconvenient to move, which has great limitations. The traditional starting method of starting the engine is easily restricted in outdoor operation, and the cost is high. Therefore, it is necessary to develop suitable starting equipment to realize the starting problem of the turbojet engine in the outdoor environment. [0003] At present, the starting device of small turbojet engines mainly adopts large equipment vehicles with built-in starting equipment, pipelines and cables. After the engine is matched to the flig...
