    Abstract: 本研究的概念主要是參考孢子囊表面張力驅動的原理,並且延續先前的設計來改良並製作出仿生尾舵,其主要的目的是將仿生尾舵應用於微飛行器(micro air vehicle﹐MAV),使之能夠達到轉向的功能,其次因裝上仿生尾舵會增加負載,因此也將對MAV的負載進行改良。
    仿生尾舵材料是使用40μm厚的不鏽鋼片,並委託外面雷射切割工廠製作,成功製作出仿生尾舵的成品。為了要使驅動的角度增大,故使用表面親水改質-沉積聚對二甲苯的方式,讓仿生尾舵的毛細結構間隙能完全吸附充滿工作液體,驅動的角度能夠提升。負載性能則是以國防大學升力較大的蝙蝠拍翼機做參考,之後將仿生尾舵裝置垂直尾翼上試看驅動的情形,期望裝上仿生尾舵能夠讓MAV達到轉向的功能,且能同時降低用電的需求量,以呈現仿生的樣貌。
    This thesis mainlu presents an animation of the sporangial motion for making bionic tail actuators of flapping micro-air-vehicles(FMAVs) regarding energy saving. A SUS-304 steel foil of 40μm thick is used as the working substrate. The actuation area of 40-50 comb-shaped cantilevers is designed to have the maximum actuating angle change about several degrees. Nd-YAG laser machining with air cooling and water cooling respectively are performed to cut off the surface tension-driven actuators. Surface modification including parylene coating and oxygen plasma treatment are added to enlarge the actuation stroke angles up to 10˚-12˚ for practical usage in flight direction control.
    Secondly, the payload modification of the FMAVs is also addressed. The added payload is for the make up of the bionic tail actuator. The design method is to assign the center of gravity in the middle of the FMAV. The tail area is so close to the flapping wing area as to generate the approximately equivalent lift to the flapping lift. The flight test of the new FMAV with wingspan of 25.5cm verifies the above design.
