A hot air balloon refers to a kind of aircraft that consists of a bag and hot air. The bag is also referred to as the envelop and it is designed in a way that it can contain heated air. The bag is connected to a wicker basket or capsule beneath it for carrying passengers. When in need of hot air balloons Colorado is the best location to check out.
A wicker basket is usually used in ordinary short-distance, low-altitude models. However, if the balloon is designed to travel over long distances at high altitudes, a capsule is used in the place of a wicker basket. The air inside the bag is in most cases heated using an open flame. When the air is heated, its density lowers that he cold air around it, making it buoyant.
As is the case with any other kind of aircraft, a balloon cannot fly in the area above the atmosphere. Gas balloons usually feature a seal at the bottom, but the seal is absent in this versions. The seal is excluded because of the surrounding pressure outside the balloon is the same as that of the air near the mouth..
When the balloon is designed to carry people, it is made of a single-layer, fabric gas bag. A mouth or a throat refers to the opening at the base of the envelop through which air is heated. Heating of air is achieved using burners placed in the basket and heating the air below the opening of the envelop. Various kinds of fuel can be used to heat the air, including propane and liquefied gas.
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 gores in the envelop varies a lot, with some having only 4 panels while others having as many as 24 sections. There is usually a crown ring at the top of the envelop. The ring is usually made of aluminum in most cases, but other metals may also be used. Load tapes attach to the ring at the top. Load tapes are sewn into loops at the bottom to attach to the basket.
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.
The envelop is made impermeable to air by applying a coat over it. Most commonly used kinds of coats are polyurethane and silicone. When the coat weakens and degrades over time, it renders the envelop ineffective. Degradation of the coat is mostly caused by moisture, heat, and mechanical wear and tear.
