Flight height control system for unmanned hot-air balloon

Abstract

The invention belongs to the technical field of hot-air balloon control, and relates to a flight height control system for an unmanned hot-air balloon. Comprising a flight control computer, a GNSS receiver, a data radio station and a main driver. The GNSS receiver is arranged in a pod of the unmanned hot-air balloon and is used for receiving current longitude, latitude, height and speed data of the hot-air balloon and transmitting the received data to the flight control computer; the data transfer radio is arranged in an unmanned fire balloon pod, and the flight control computer communicates with the ground control station through the data transfer radio; the main driver is arranged in the pod and comprises a fuel tank, a combustor and an igniter; the fuel tank is used for storing and supplying fuel to the combustor; the igniter is used for igniting the combustor, and the combustor is used for heating air in the hot-air balloon; the flight control computer receives a height instruction sent by the ground control station, compares the height instruction with the current height of the unmanned hot-air balloon and controls the combustion time of the combustor according to a comparison result so as to control the flight height of the unmanned hot-air balloon.

Description

technical field [0001] The invention belongs to the technical field of hot air balloon control, and relates to a flight height control system for an unmanned hot air balloon. Background technique [0002] A hot air balloon is a common aircraft that uses hot air with a density lower than the ambient air inside the balloon to generate buoyancy. The bottom of the hot air balloon balloon is equipped with an opening for heating the cold air and a hanging basket. The opening is facing the flame injection port of the burner. The burner is erected directly above the hanging basket, and the hanging basket is loaded with high-pressure gas cylinders containing propane or liquefied petroleum gas. . Compared with other aircraft, hot air balloons not only have the advantages of long suspension time, stable state, and high economic efficiency, but also can use the thermal expansion characteristics of the air to heat the air in the balloon through the heater it carries to adjust the air te...

Problems solved by technology

[0005] Generally, hot air balloons are mainly used for sightseeing tours or air performances. Hot air balloon pilots manually control hot air balloons to fly. At present, unmanned hot air balloons are rarely seen, and there are basically no public documents on the flight control system for unmanned hot air balloons.
