The dual-spinning projectile consists of two parts, that is, a forebody
(with canards) and an afterbody, and the two parts are connected through a ball bearing.
The premixer/burner system was composed of three concentric axisymmetric disks connected along their axis with a vertical hollow tube, namely, a forebody
disk (C), a hollow fuel injecting disk (B in Figure 1), and the flame stabilizing afterbody (A) ([D.sub.b] = 0.025 m).
Oesophagus shorter than pharynx, intestinal bifurcation in posterior third of forebody
; caeca becoming wider in hindbody and terminate fairly close to excretory vesicle.

Here we are installing the upper forebody
blocks of syntactic foam.
Under normal circumstances, hypersonic vehicle is designed as the special slim construction such that the aerodynamic forces suffered from the forebody
section are large enough in comparison to the other parts.
Both the forebody
and the tail of the shape corresponding to the smallest thickness ratio D/L =0.1 are concave, while for less slender bodies (D/L = 0.21 and D/L = 0.3) only the tail is concave (see Figure 3).
The current aerodynamic design for hypersonic vehicles is mainly for the demonstration vehicles which focused on minimizing resistance and the optimal matching between airframe and engine, and the forebody
and engine inlet integrated design is the key issues for the configuration design.
Body divided into a relatively large, dorsoventrally flattened forebody
, much smaller hindbody with maximum width occurring pre-acetabular (Fig.
