Wing parameter configuration and steady motion analysis of water-jet hybrid glider

The theoretical calculation, numerical simulation and tank towing test results were compared to verify the accuracy of the numerical simulation method for calculating hydrodynamics of water-jet hybrid glider. Considering the influence of the wing on the gliding efficiency and static stability of the water-jet hybrid glider, the wing parameter configuration was determined by designing the orthogonal simulation test and the Whicker formula. The dynamic model of a water-jet hybrid glider was established based on a rigid body six degree of freedom dynamics model, and the motion simulation was performed for the steady gliding motion and the horizontal rotary motion. The results showed that with the increase of the displacement of the centroid adjustment block during the gliding motion, the attack angle decreased, and the gliding angle and the gliding velocity increased; the rotation radius and rotation period decreased with the increase of the rudder angle during the horizontal rotary motion, and the faster the velocity was, the better the rudder adjustment effect was. The results make reference to the design and application of water-jet hybrid glider.
