一种新型低压油气减震器的研究

The Development for a New Oleo-Pneumatic Shock Abserber of a Mini UAV

运用流体流经限流孔产生阻尼原理和气体弹性原理，研制出一种新型的低压油气减震器，它既能有效地减震又能可靠地收放，使用维护方便，是一种能保证无人机安全回收的新型减震器。

A new shock absorber of low pressure oleo-pneumatic was developed for a miniatureUAV to satisfy it's speign specification of Tetractable and shock absorber applied the pricipleof orifice damping and gas elasticity. lt absorbs the majority of landing impact energy mainlyby fluid resistance and retracts or extends by gas compressing or expanding Exnerimentsand flight tests showed that the shock sbsorber damping effectively and proved reliable extend and retraet as well as easy maintenance. It is a new shock. absorber which redues theUAVIS dynamic drag and guartees safe recovery.
