Hot air balloon is made up of five parts which are ball bag, burner, basket, gas bottle and fan. It can be equipped with height speed instrument, pressure increasing device and moorage rope etc.. And it also can be equipped with GPS, interphone, anemoscope and fast uninstall lock etc..

Flight theory

Flight theory of hot air balloon is rising action produced by the effect of hot air lighter than general air. Adjust the temperature in the ball bag to control the whole balloon’s rising or descending by commanding the interval time of burner’s burning or flameout. To control and adjust direction of going ahead by utilizing different wind direction of different height. The flight speed of hot air balloon is same as wind speed.

Specification division

The international balloon council divides the standard hot air balloon to four classes: ball volume is 2000-2400stere as seven class; ball volume is 2400-3000stere as eight class; ball volume is 3000-4000stere as nine class; ball volume is 4000-6000stere as ten class.

Technique specification

The main technique specification of domestic generally used hot air balloon which is seven class is as follows:

Ball bag volume:2000-2400stere　　 ball height:23metre
Ball max.: Φ17metre　　　　　　　 ball breadth quantity:24
Burner: double nozzle　　　　　　　steel bottle:20KGΧ4
Fuel: LPG or propane　　　　　　　 basket:1.4Χ1.1(m)
Fan: four stroke 5.5 horsepower　　system weight: 285kb
Effective load: 700kgf　　　　　suggestion using load:450kgf
Instant max. temperature:130℃ rising rate:›3.0m/s at 120℃
Gross rising rate: 715kgf at 130℃ flight max.height:7000metre

Weather condition

In the day-flight, wind speed is ≤6m/s, visibility is ≥1.5kilometre, no rain;

In the night-flight, wind speed is ≤3m/s, no rain.

Ground requirement

The ground for rising and landing will be plainness and wide, and the area is no smaller than 40MΧ40M.

The air condition of rising the balloon or entering the arena will be good. No barrier such as high-pressure wire and building etc. which are dangerous for flight.
