The gores, which extend from the base of the envelope to the crown, are made up of a number of smaller panels. Nylon works very well in balloons because it is lightweight, but it is also fairly sturdy and has a high melting temperature. The skirt, the nylon at the base of the envelope, is coated with special heat-resistant material. The hot air won't escape from the hole at the bottom of the envelope because buoyancy keeps it moving up.
If the pilot continuously fires the burner the balloon will continue to rise. Hot air balloons also have a cord to open the parachute valve at the top of the envelope. When the pilot pulls the attached cord, some hot air can escape from the envelope, decreasing the inner air temperature.
This causes the balloon to slow its ascent. If the pilot keeps the valve open long enough, the balloon will sink. Most hot air balloons use a wicker basket for the passenger compartment. Wicker works very well because it is sturdy, flexible and relatively lightweight. The flexibility helps with balloon landings: wicker material flexes a little, absorbing some of the energy. Balloons have set minimum and maximum loading capacities. Large balloon baskets are usually rectangular and are split into comfortable compartments for three or four people, giving everyone a fantastic view.
Surfaces are covered in smooth leather and there are foot holes in the side of the basket so passengers can climb in and out. Many of our Virgin balloon baskets have bench seats which can be used for landing. It is fixed to a metal frame attached above the basket under the mouth of the envelope.
The burner mixes liquid propane from pressurised gas tanks with oxygen and ignites it. The pilot pulls a small valve which fires the burner and aims the flame into the mouth of the balloon to heat the air inside. Our balloons have two burners including one which lets propane out more slowly making it quieter.
Our balloons generally also have specially-fitted heat shields below the burners which stop it getting too toasty for you but we still recommend a hat. Hot air balloons work because hot air rises. By heating the air inside the balloon with the burner, it becomes lighter than the cooler air on the outside. This causes the balloon to float upwards, as if it were in water. Obviously, if the air is allowed to cools, the balloon begins to slowly come down. Pilots have a great deal of control over the altitude of the balloon which they monitor with various instruments.
Balloons cannot be steered in the normal sense of the word so they travel in the direction of the wind, which varies at different altitudes. We often get asked these questions by guests and we are more than happy to share the ins and outs as to how hot air balloons work with you here: How does a hot air balloon work?
Our baskets are handwoven rattan, an extremely resistant, durable yet light material. While baskets can vary in size, some holding just two people, larger baskets can carry groups of up to 20 people. Our baskets are designed so that, even when carrying a large group, every individual is comfortable and has sufficient viewing space to enjoy the spectacular scenery and experience to the max. Envelope - Balloon- this is the colorful part of the hot air balloon and is the part that gives the structure that magical, colorful characteristic.
Made from a technical, specialized material, it has an opening which allows air density inside the balloon to change necessary for the balloon to rise and stay up.
Our choice of quality means you are in the safest hands when you chose Napa Valley Balloons for your spectacular ride. Burner - the burner is the mechanical part of the balloon and is basically what makes it work. Propane cylinders are used to produce hot air allowing the balloon to rise. The burner, which is positioned inside the envelope, heats the air and, as needed, the pilot allows the air to cool, if he wants the balloon to come down, or heat up, to make the balloon rise again.
