This paper examines the flight dynamics of an underwater glider using a passive flapping-foil glide concept. Therefore an analytical description of the gliding path, based on the acting hydrostatic and hydrodynamic forces is introduced. Afterwards, a study based on computational fluid dynamics for various flow cover geometries is conducted. Based on the simulations a suitable flow cover is selected. Lastly the chosen geometry is fabricated as a model and examined in wind tunnel tests. Based on the experimentally determined force coefficients and the before introduced theoretical relationships, the system's gliding movement can finally be calculated and statements regarding glide efficiency are made. The results are compared to the conventional glide concept used in today's legacy gliders and are discussed.
