1.前言 L8飞机是中外合资,国际合作由南昌飞机制造公司(NAMC)研制的新型喷气教练机。主要用于基础训练。能担负起落、航行、编队、仪表飞行、复杂特技和攻击等训练任务。其研制的目标首先是打进国际市场,同时还要满足国内用户的要求。为了使L8在剧烈竞争的国际市场上具有很强的竞争力。NAMC经过认真、细致的调查分析后认为要使L8取得成功,必须对传统的设计思想进行改革。改革的核心之一是用效能取代单一的性能。即只有对L8进行性能、可靠性和维修性(R&M)、费用的权衡设计,才能保证L8具有良好的性能、安全性、战备完好性、任务成功性和较低的寿命周期费用。NAMC 1. Foreword The L8 aircraft is a new type of jet trainer developed by Nanchang Aircraft Manufacturing Corporation (NAMC) as a Sino-foreign joint venture. Mainly used for basic training. Can take up and landing training, navigation, formation, instrument flight, complex special effects and attacks and other training tasks. The goal of its development is first to enter the international market, but also to meet the requirements of domestic users. In order to make L8 in the highly competitive international market is very competitive. After careful and detailed investigation and analysis, NAMC believes that to make L8 a success, it must reform traditional design ideas. One of the core elements of reform is to replace single performance with performance. That is, only the L8 performance, reliability and maintainability (R&M) and cost trade-off design can ensure that L8 has good performance, security, readiness for completion, mission success, and low life cycle costs.
