Embodiment Construction

[0069] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0070] A parametric method applicable to the shape design of a wing-body fusion underwater glider includes the following steps:

[0071] Step 1, dividing the projection of the shape of the wing-body fusion underwater glider under the three-dimensional Cartesian coordinate system into a plane shape and a cross-sectional shape;

[0072] Step 2. The planar shape of the glider contains ten control points in total, and the profile line of the planar shape can be calculated by giving the coordinates of the control points;

[0073] Step 3, dividing the plane parameters of the glider into a curved airfoil and a straight airfoil along the span direction, wherein the curved airfoil section includes 8 position control points, and the straight airfoil section includes 4 position control points;

[0074] Step 4, the curved airfoil on the plane shape of the glider is controll...

Abstract

The invention relates to a parameterization method capable of being applied to wing body fusion underwater glider shape design. The method includes: dividing a glider parameterization shape into a plane shape and a section shape; generating parameter equations of a front-end Bessel curve, a front-end linear airfoil profile, a rear-end Bessel curve and a rear-end linear airfoil profile; calculatingthe variable quantity of the section airfoil profile, and applying the variable quantity to the selected section shape reference airfoil profile curve to obtain changed section airfoil profile parameters; calculating a span value and a height value corresponding to each section wing section to obtain a coordinate value of the actual section wing section of the parameterized appearance; and combining the glider plane shape parameters and the section airfoil parameters, and setting out the curve group to obtain the actual glider geometric shape. According to the parameterization method, parameterization of various similar types of gliders such as the wing body fusion underwater glider can be effectively carried out, the application range is wide, the parameter significance is clear, appearance design and optimization of the wing body fusion underwater glider are facilitated, and the parameterization problem is solved for research of hydrodynamic performance of the glider.

Description

technical field [0001] The invention belongs to the technical field of underwater glider design, and relates to a parametric method applicable to the profile design of a wing-body fusion underwater glider. Background technique [0002] As a new type of underwater vehicle, the underwater glider changes the state of motion by adjusting the buoyancy, and converts the lift on the wings into propulsion. It has the characteristics of long voyage time, long voyage distance, and low energy consumption, and provides convenience for monitoring the marine environment and exploring natural resources, so it has received extensive attention. As an unconventional underwater glider, the wing-body fusion underwater gliding wing adopts wing-body fusion technology to make the glider have a higher lift-to-drag ratio, and various performance indicators have been greatly improved, which can significantly improve Gliding efficiency. The shape of wing-body fusion underwater glider is composed of ...
