High Altitude Glider Solution for Returning From Space

Sammanfattning: Space exploration drives the human expansion inthe universe. Succeeding in this challenge demands familiarityof the near earth space environment, achieved through soundingrocket experiments that often are lost upon return from space. Afuture proof solution is needed and this study aims to investigatethe aerodynamics of a modular self returning glider attachment.To aid conceptual design, simulations were first performedusing potential theory in the software XFLR5. The resultingdesign was then analysed further using Computational FluidDynamics (CFD) in Simscale after which a glider prototype wasbuilt and tested.The study shows that while it is possible to fulfill the projectrequirements when only modelling the wing surfaces, the gliderfuselage contributes to a destructive drag and pitching moment.Consequently, future prototypes demand increasing the lift orreducing the drag, as well as ensuring longitudinal stability. Moreresources need to be invested into further CFD modelling andprototype testing.
