摘要：
In order to make the error of aero-engine reliability model smaller, error analysis was made for traditional aero-engine reliability model, the reason that reliability indexes over expand was pointed out, and the aero-engine reliability model based on failure modes in structural system considering aero-engine structural system and the failure mechanics characteristics was established. The reliability calculation method of each layer was given. Structural system reliability model of aero-engine based on failure modes, which considers relative independence, timeliness and time varying of failure rate, can avoid problems such as missing important failure modes and over expansion of reliability index, so it has great engineering application value. © 2016, Editorial Department of Journal of Aerospace Power.
