A vehicle is provided that is amphibious to include submersible operations. The vehicle has wings configured to generate a sufficient dive force to oppose buoyancy of the vehicle, when desired, which are disposed on opposing sides of a central hull. The vehicle is configured to enable easy transition from land operations to water operations, to include water surface travel as well as submerged travel.

A positioning system is provided for use in a wind tunnel that results in accurate and dynamic orientation for a model while reducing aerodynamic interference. The system includes a pitch-yaw sleeve having a generally cylindrical shape and a torque tube disposed askew within the sleeve and rotatable about its longitudinal axis to drive a shaft. The shaft is generally elongated and crooked. The sting, to which a model is affixed, is rotatably attached to a distal end of the shaft. Rotation of the pitch-yaw tube and/or the pitch-yaw sleeve provides precise pitch and yaw orientation of the model, and rotation of the sting relative to the shaft provides precise roll orientation.
