It sets in cross-shaped empennage 6, includes symmetrical horizontal stabilizer and elevator, fixed fin and rudder, i.e. tail
A pair of of wing in the wing 6 is arranged in parallel with the lift wing 4, and another pair wing is vertically arranged with the lift wing 4, in the trailing edge of each wing
Place is respectively provided with a rudder face 7, to control the lifting of hull 1 and direction.Hull 1 be internally provided with control hull 1 float or under
Heavy power set 9, and be connected on 9 both sides of power set extend to 1 both ends of hull for its intake and exhaust
Pipeline, wherein, tip one end connecting pipeline is nozzle 10, is air inlet 8 with respect to tip one end connecting pipeline.The power
Device 9 includes main gasbag, compressor and gas bomb to charge and discharge air full of helium, and the buoyancy generated by helium makes
Dirigible lift-off is obtained, and passes through and compressed air and discharge air is filled in compressor gas bomb, to change the density of dirigible, is needed
It is noted that dirigible only starts compressor compresses air in peak, own wt and averag density are improved, so as to fulfill nothing
Power glides, and in minimum point without using the energy, only sprays compressed air generation onward impulse backward by opening nozzle, together
When reduce own wt and averag density and realize and float so that dirigible is according to zigzag flight path glide maneuver, such as Fig. 4
It is shown, but since dirigible has sinking or the speed to float always in entire flight course, posture and track are controllable,

Power set are compressor, which is used to be filled with compressed air to gas bomb, and when being charged to specified air pressure, full ship weight should be shown
It writes and is more than the gross buoyancy that the ship generates, conversely, after gas bomb releases air therein, full ship weight should be significantly less than this
The gross buoyancy that ship generates.When dirigible is on ground, the compressed air of certain pressure intensity is full of in gas bomb, the weight of air counteracts
The buoyancy that main gasbag generates.When dirigible takes off or glides upwards, drain tap is opened, backward by the compressed air in gas bomb
Discharge makes the gravity of dirigible be less than suffered buoyancy, and climbs under buoyancy, during floating, is controlled by empennage 6
