Abstract
The control surface according to the present invention controls an attitude of a flying object, and includes a skin covering an internal space and a lattice structure supporting the skin in the internal space. The lattice structure has mechanical strength that is changeable in one or both of a surface length direction and a surface width direction. For example, the mechanical strength at a root of the control surface in the surface length direction may be made larger than the mechanical strength of other regions in the surface length direction, or the mechanical strength at a front edge and a rear edge in the surface width direction may be made larger than the mechanical strength of other regions in the surface width direction.
Claims15
A flying object, comprising:
- a main body of the flying object;
- and
- a control surface configured to control an attitude of the flying object, the control surface being mounted on a rear end part of the main body of the flying object,
- the control surface comprising:
- a skin covering an internal space;
- a lattice structure that is provided in the internal space and supports the skin;
- and
- a control shaft that is attached to the main body of the flying object,
- wherein:
- the main body of the flying object includes an engine that is configured to provide propulsion force to the flying object and an actuator that is configured to rotate the control shaft of the control surface;
- the lattice structure is constituted by a plurality of rectangular parallelepiped unit lattices;
- and
- a size of the lattice structure varies through variation of one or both of a lattice diameter and a length of each of the plurality of rectangular parallelepiped unit lattices.
