Hot air balloons are categorized as aircraft. They have a bag, which is also called an envelope incorporated as one of the most important components. The design of the bad allows it to keep air when it is heated. As such, when in search of hot air balloons Colorado presents among the best locations to consider making a visit to.
Traditional low-altitude, short-distance models of these products incorporate wicker baskets. However, models that are designed to go long distances and achieve high altitudes incorporate a capsule instead. An open flame is usually used to heat interior air inside the balloon. Heating air reduces its density in comparison to the surrounding air, which makes it buoyant.
These balloons are incapable of flying beyond the atmosphere just like all kinds of aircraft. As opposed to gas balloons, these balloons do not need to be sealed at the bottom. The reasoning behind this design is that the air near the bottom of the envelop has the same atmospheric pressure as the surrounding environment. This technology is the first-ever human-carrying flight technology in the world.
A balloon that is meant for human flight is usually made using a single-layer, fabric gas bag. The bottom of the bag has an opening called a throat or mouth. The basket that is attached to the envelop is usually mounted with burners that are centered to the mouth of the envelop. The burner injects a flame into the bag to heat the air inside it. Liquefied gas and propane are some examples of fuels used in the burners.
Dacron and ripstop nylon are some of the materials used in making the envelop. During production of the envelop, the material is cut into smaller panels that are then sewn together to form the whole bag. Load tapes are also sewn together with the panels so that they can be used to hold the gondola. The names gores or gore sections are used to refer to the panels, which run from the crown of the bag to the bottom.
The number of gore sections included in the envelop vary a lot. Some have few gores such as four while others have large umber numbers of gores, reaching 24 in some cases. A metal ring is incorporated at the top of the envelop. Load tapes to which the basket is attached attach to the ring at the crown. At the bottom, load tapes are made into a loop for the basket to attach to.
A method called French fell, double lap seam, or French felled is used for sewing panels of the envelop together. In this method, fabrics are folded over one another at their edges, with the load tape included and then sewn using two rows of paralleled stitching. Other methods that may also be used instead of French fell are zigzag and flat lap.
Coating is applied on the envelope to render it water and air-tight. Coatings that are commonly used are silicone and polyurethane. When these coating wear out due to degradation, the effective life of the envelop ends. Degradation is caused by several different reasons including heat, mechanical wear and tear, and moisture.
