Welcome to glypo.com
This is glypo.com, a technical blog and collection of tools focused on applied aerodynamics and amateur rocketry.
The site brings together literature review, numerical analysis, and personal research, with an emphasis on practical engineering insight.
Ground Effect Vehicle Aerodynamics
The airflow around a wing operating in close proximity to the ground differs significantly from that of a wing flying at altitude. The presence of the ground produces an aerodynamic effect that can increase lift without a corresponding drag penalty, thereby improving aerodynamic efficiency.
This phenomenon is known as ground effect (often referred to in the WIG literature as in-ground effect) and underpins a class of vehicles variously referred to as Wing-In-Ground-effect (WIG) craft, Ground Effect Vehicles (GEVs), or by the Russian term Ekranoplan. These vehicles occupy an unusual niche: neither conventional aircraft nor surface vessels, they operate within metres of the surface—typically water—at speeds far exceeding those of traditional marine craft. However, there are practical and operational limitations.
This site includes posts and tools exploring the aerodynamics of GEVs through a combination of literature review and original research using computational fluid dynamics (CFD).
Rocketry
The site also documents my amateur rocketry work, including design studies, simulations, and the development of supporting analysis tools.
