Hot Air Balloon

Hot Air Balloon

Hot air balloons are a leisure flying air vessel that uses warm air from burning propane, as energy. Hot air balloons have three main parts: an envelope or balloon, a basket, and burners. The envelope is a bag of strong nylon fabric with an opening at one end called a mouth. The basket is used to carry passengers and is attached to the envelope with very strong metal cables. These balloons can carry 2-24 people depending on their size. The burners of the balloon are the “engine”. A simple scientific principle powers hot air balloons: warm air rises in cooler air. The mass per unit of volume of warm air is less than cold air.

To keep the balloon moving, there must be a way to keep reheating the air; this is where propane comes in. Under the envelope there are burners positioned with propane tanks connecting to them. The propane tanks mix with pressurized oxygen and ignite it. The pilot directs the flames into the mouth of the balloon to heat the air through a small valve. To make the balloon move downwards, the pilot opens the parachute valve. The parachute valve is a circle of fabric cut at the very top of the balloon, or envelop, controlled by a long cord. The cord runs down the envelop to the basket. To land, the pilot pulls the cord to let the hot air escape. The cool air lets it ascend. Since they are not like helicopters or planes they cannot land in pre-designated places, this is the reason air balloons are flown in the countryside or empty plots of land.

The pilot asks the passengers to crouch down to avoid any injuries when landing the balloon. As the balloon approaches the ground, the pilot opens the parachute valve, as mentioned before, all the way to release all the hot air. Sometimes the landing is rough, but the modern technology of air balloons improves their landing. These balloons are an exciting experience from the serene view of the clouds and below, to the exhilarating launching and landing.

Hot air balloons have been enjoyed since the very late 1700’s. These flying vessels provide a very exciting experience from the serene view of the clouds to the landing and take off. Despite the accessibility of technology, the best way to learn about a hot air balloon is to ride on for yourself!
