碩士 / 國立成功大學 / 航空太空工程學系 / 83 / Except takeoff and landing, the airship doesn't contact the
water surface during the flight. Even though the airship is
named as ``ship'', it is really a kind of aircraft, because it
cruises at several feet height over the water surface. Due to
the ground effect, the airship possesses good aerodynamic
performance. No matter that it is used for business transport
or military supply, the airship is more flexible and efficient
than the traditional ship. For the country, which has large
terrorital water or many islands, the airship is a high-load,
low-fuel-consumption and new economical traffic vehicle. The
main purpose of this thesis is to study the aerodynamic
behaviors of the two-dimensional airship airfoil over the sea.
For the different values of flight speed, altitude, wave
magnitude and wave length , the interaction between airship
airfoil and sea wave is investigated. Meanwhile, the effects of
jet on the aerodynamic behaviors are studied when the jet is
located on the undersurface of airfoil. From the present
numerical study, the obtained aerodynamic coefficients can be
used as the reference of airship design.
