Research of Modeling and Simulation of Aviation Ignition Equipment
Abstract:
Ignition energy of aviation ignition equipment is an important parameter for reliable launch of air jet. The factors are quite more that influence ignition energy and increasing the charge voltage of capacitance with high efficiency is an approach which increasing ignition energy efficiently. The charge voltage is the output voltage of switching power of ignition device. A mathematic model was constructed for switching power, and a mathematic expression were deduced about output voltage uo with input voltage ui and other elements parameters of switching power supply. An important conclusion were obtained which uo mainly depended on input voltage ui, load RL, dynatron collector peak current ICM on certain condition through a smart transform. When increasing ui, RL, ICM , uo increasing observably. The PSpice circuit simulation software is used for simulation, and the results show that the above conclusion is valid and feasible.
