In traditional aircraft design, airframes and engines are designed separately and bolted together. This leads to inefficiencies due to additional drag. The approach also leads to propulsive inefficiencies via non-distributed propulsion. Hovering and VTOL requirements introduce even more complexity, size and weight to the system. Jetoptera’s design is a …

Traditional missiles powered by rocket motors typically carry both fuel and oxidizer. An air-breathing ramjet missile can dispense with the separate oxidizer payload, reducing the size of a propulsion package. Thanks to ramjets, smaller missiles use that space for other things, like a bigger warhead or more fuel. Ramjets, according to …

A miniature UAV or small UAV (SUAV) is an unmanned aerial vehicle small enough to be man-portable. Miniature UAVs range from micro air vehicles (MAVs) that can be carried by an infantryman, to man-portable UAVs that can be carried and launched like an infantry man-portable air-defense system. The term is …
