Abstract

Abstract:

The cartridge starting characteristics of the two spool turbofan engine were researched by computer simulation. A mathematical model is developed from the generalized model by modifying the method of accounting for the effect of the low pressure spool. Compared with the testing data, the simulation results can easily evaluate the main factors that affect the starting characteristics. The developed mathematical model is also useful for studying the starting characteristics of other types of gas turbine engines with cartridge starters.

Key words: turbofan engine, cartridge starting, cartridge starter, starting characteristics
