Objective To introduce and discuss the fundamentals of earned value project management Work Breakdown Structures Program plans and schedules Earned value management systems Cost and schedule variances Estimates at completion

How do you start? Assume the audience is technically competent, but isn't familiar with your project? What do they need to know first?

accelerations account for non-central forces(drag, thrust, etc. X-axis in zenith, y-axis in frames velocity, and z-axis in transverse directions 8 Free orbit solution where 'A and 'B' are lengths and'a andB are phase angles

Definitions What is Systems Engineering? the ensemble of coordinated analyses, simulations, and processes which lead to a technical product which best meets the needs of an identified customer What does it mean to manage systems engineering?

7.1概述 功用:保证发动机正常工作的所需的“神经”系统组成:主要有滑油、起动、燃油与调节系统,以及保证它们正常运行的传动系统。有的机种还有喷水、冷却系统等。(为防内容重复,本章主要介绍滑油、传动系统) 7.2滑油系统

发动机总体结构通常可分为转子、静子与附件及其传动三大部份。发动 机(转子)的支承就是指转子向静子传递负荷的必经的关键部位,也是发动机 的最薄弱环节之一。显然,它的布局(方案)对发动机总体结构至关重要

5.1燃烧室 (本节应注意与燃烧课程的协调,避免重复) 5.1.1概述 (1)功用:将燃的化学能转换成气体的热能并加热到涡轮前允许的温度。 (2)燃烧环境:

3.1概述 (1)功用 利用涡轮传来的旋转机械功,提高流过气体的压力,以提供发动机工作时所需要的压缩空气。 (2)结构形式 1 按气体流动方向

由结构完整性计划看出,载荷与载荷谱的确定是实现计划的首要条件。 2.1载荷、载荷谱及其在结构设计中的作用 2.1.1静载荷是发动机结构静强度设计的基础

1.1基本类型 1.1.1活塞式+螺旋桨 汽油机等容循环(OTTO循环) 柴油机—等压循环(Disel循环) 做功特点: (1)进气量小 (2)各冲(过)程在同一汽缸内按序完成(个体作业”)→功率(生产率)受限
