Description
Technical field
The present invention relates to stratospheric airship technical field, more particularly to a kind of energy resource supply system of advection layer solar dirigible
System and control method.
Background technology
Dirigible is a kind of lighter-than-air craft, and difference lies in fly with propulsion and control with fire balloon maximum for it
The device of state, specifically by huge streamlined hull, the gondola below hull, the tail surface for playing stability contorting and
Propulsion device forms, and the small buoyance lift gas of density ratio air is filled with the air bag of hull（There are hydrogen or helium）So as to producing buoyancy
Dirigible is gone up to the air, gondola for personnel take and load cargo, tail surface then be used for control and go as course, the stabilization of pitching.With
The technological progress of Novel light high-strength degree composite material, the isostructural design of covering, skeleton and processing all there occurs great variety,
Modern dirigible mainly develops to three directions of flying height of the load benefit of bigger, longer hang time and higher.
Atmosphere is generally divided into six layers of troposphere, stratosphere, intermediate layer, heat zone, outer atmosphere and loss layer, from height above sea level
It is only stratosphere that 11 kilometers, which are played 32 kilometers, this atmosphere quality accounts for the 20% of total amount.Divided by flying height, dirigible can divide
For troposphere and stratospheric airship, stratospheric airship is generally in 20 kilometers or so of high-altitude flight or hovering, the flight range gas
Temperature, almost without condensation vapor, without meteorologies such as thunder, electricity, also without the convection current up and down of air, utilizes advection not with height change
Layer dirigible can stay empty platform progress telecommunication, earth observation, resource investigation and patrol early warning etc. as long-term.
Three kinds of modes below the energy supplyystem generally use of stratospheric airship in the prior art：
（1）Individually by the way of carrying the storage battery energy and power is provided, but since storage battery volume is larger in such mode,
Manipulate inconvenience, once be finished do not charge in time if energy can not be provided again, and also can be with without other power supplys in stratosphere environment
Give its charging.
