We present a conservative occlusion culling algorithm for large environments. As part of a preprocess, we decompose the scene using a spatial subdivision and render the primitives at runtime in a front-to-back order. Our algorithm uses hardware accelerated occlusion queries to test the visibility of more distant volumes of space in a progressive manner. The resulting algorithm is simple to impl...

In conventional aircraft design, engine loads are transferred directly from the core and fan case to pylon via mounts. Literature is available on modeling of individual powerplant components, but limited work whole assembled system (engine, pylon, nacelle). The influence structural connections between components overall performance has not been investigated. Herein, a finite element model descr...

The conventional powertrain for ultralight aviation consists of a fixed pitch propeller connected to an internal combustion engine (ICE). Since ICEs have limited thermal efficiency (<40%), new and more efficient powerplant configurations recently been proposed in the scientific literature by adopting hybrid electric solutions. Hybridization has additional benefit increased safety thanks redu...
