大过载条件下无人机的发动机滑油系统

The Technical Analysis of UAV Engine Lubrication System Stabilization in the Condition of High Load Facor

与常规有人驾驶飞机相比,无人机除要求的高推重比外,还要具有抗高机动载荷能力等优点,可以主要以任务为中心来设计,而不用考虑人的因素。因而飞机的速度、高度和机动性可以有很大的突破,机动能力也可以成倍增长。润滑系统是发动机的重要组成部分,可决定发动机能否安全、可靠地工作。滑油系统的设计与发动机的用途和使用条件密切相关,本文针对无人机的使用特点和要求,对发动机滑油系统进行了简要的分析,并提出了一些设计方案。

Unmanned aircrafts, besides higher thrust-weight ratio compared with manned aircrafts,are characterized by high maneuverability and anti -G capability, which may be mission-focused designed without put in any consideration of man. Thus the flight speed, altitude and maneuverability will be a great breakthough that means its maneuverbility will be multiplied. As an important element of engine, the lubrication system will determine wheather the engine will work safely and reliably. The design of lubrication system has a strong connection with the purpose and service conditions of engine. This article, according to the characteristic and requirement of ummanned aircrafts, briefs on the lubrication system of the engine,and provides some design plans.
