Technical Field
The invention relates to an airship lateral pushing support structure, in particular to a semi-hard stratospheric airship lateral pushing support and a semi-hard stratospheric airship.
Background
The stratospheric airship has very wide military and civil values, and has great application values in aspects such as missile defense, anti-terrorism, communication, remote sensing, space observation, atmospheric measurement and the like. However, the flight altitude of the stratospheric airship is generally around 20km, the surrounding atmosphere is very thin, and the density is about 1/14 of the air density at the bottom edge, so that the size of the stratospheric airship is very large to meet the requirement of the load of the stratospheric airship, and the stratospheric airship has the phenomenon of over-temperature and over-pressure due to the influence of solar radiation, so that the structure of the airship is very easy to damage. The average wind speed of the stratosphere is 10m/s, the maximum wind speed can reach 40m/s, and the test is very large for the structural stability and flight control stability of the airship.
In a common medium and low altitude airship, a pod is put on the bottom, and a power system bracket is mounted on the pod. The method places the engine bracket at a position which is too large downwards from the floating center of the airship, and the efficiency of the airship propulsion system is seriously influenced due to unreasonable layout; meanwhile, the influence of the moment is easy to generate a wavy flying state which fluctuates up and down when the airship flies horizontally, and the wavy flying state needs to pay more energy compared with the horizontal-flying stratosphere airship. And because the bottom pod is protruded, the resistance coefficient of the airship is increased, and the airship needs to pay more energy.
At present, most of airships adopt a tail-pushing structural design, a propulsion support structure is provided in Chinese patent application with publication number CN105644762A, a lower rigid structure adopts a light composite truss structure, and non-vector propulsion propellers are arranged on the left side and the right side of the structure. By adopting the structure, the airship is easy to generate wavy flying jolt up and down during flying, the flying stability is poor, and the ground observation effect is influenced.
Therefore, it is highly desirable to provide an airship side-thrust support that can reduce the vertical heave of an airship during flight and improve the stability of flight control.
