Abstract: Methods of manufacturing of aerospace structures are disclosed. More specifically, methods of manufacturing relatively lightweight yet strong aerospace structures. In one embodiment, the method includes the addition of a volume of a rigid and flexible polyurethane mixture into a mold to create a composite structure. In one aspect, the method includes the integration of special structures within a larger structure to remove traditionally structurally weak or vulnerable areas.

Abstract: An electrically decoupled jet engine. The electrically decoupled jet engine includes a combustion chamber which creates a toroidal flow of air and a rotational electric motor which drives a fuel supply into the combustion chamber. The toroidal flow of air is mixed with the fuel and combusted in the combustion chamber to create thrust.

Abstract: Rotary-winged vehicle systems and devices are disclosed. In one aspect, one or more engine components are mounted within rotor blades of the rotary-winged system. In one embodiment, engines are mounted within the rotor blades, with exhaust ports positioned at the rotor blade tips. In another embodiment, the engine of a rotary-winged vehicle includes a centrifugal compressor co-axially mounted with a spindle of the rotor blades. In one aspect, the compressor of one or more engines is decoupled from the engine turbine and electrically driven. In one aspect, the rotary-winged vehicle may be operated autonomously.
