Structure characteristics analysis of flying-wing vehicle

In order to research structural properties of flying-wing vehicle,half wing span static /dynamic model and all wing span static /dynamic model were established,and some dependent tests were done. The results show that the main structure bending and torsion deformation occur at the outer wing. The inner wing torsion is positive,and the outer wing torsion is negative. The spar axial force is increased from outer wing to inner wing. The spar axial force is the biggest at the separation between inner wing and outer wing,and then the spar axial force is decreased. The spar axial force also has central tendency from leading spar to rear spar.The structure flexural rigidity and torsional rigidity are enough,and the flutter can't happen.
