    Jet vanes

    Was watching a video about someone making a homemade surveillance drone using an edf propulsion. The drone looks like a Tomahawk missile but has an X tail configuration with internal jet vanes.

      Jet vanes don't work unless a significant portion of the surface is external of the nozzle.

        Old still useful concept. In 1942 The German A2 Rocket known (V2) used carbon thrust vanes for the 60 second burn time for steering by gyroscope the same ways since the rocket initially on takeoff needed very positive control in the very slow first seconds of the rockets flight since the exterior fins where useless at that portion of the vehicles flight.

        But that aside except as a fun intellectual exercise, I don't see the advantage vs its added complexity. Unless it needs rapid abrupt maneuvering to counter lasers? The exterior tail surfaces are ample enough. For normal aerodynamic use. Being used for drone vertical launch?

          One of those bloody V2 rockets blew up my Dad's house. Thankfully everyone was out at the time. They had to live in prefab for a few years after that.

            Meant for stability control during hand launches
